This guide breaks down exactly how each of the top 5 cast iron seasoning oils performed, who they’re best for, and the science behind choosing the right one for your cookware.

5 Best Oils for Seasoning Cast Iron of 2026

After weeks of applying, heating, and cooking, I’ve narrowed down the contenders to the five best cast iron seasoning oils you can buy. My selection process focused on durability, ease of application, and the quality of the final polymerized layer. Each oil on this list excels in a specific area, ensuring there’s a perfect match for every type of cast iron user.

1. Best Overall: Field Company Cast Iron Seasoning Oil – For a durable, restorative blend.
2. Best Single-Ingredient: La Tourangelle Grapeseed Oil – For high-heat performance and versatility.
3. Easiest Application: Lodge Cast Iron Seasoning Spray – For convenient and even coating.
4. Best for Cleaning & Odor Control: CARON & DOUCET Cast Iron Seasoning & Cleaning Oil – For a non-rancid formula that deodorizes.
5. Best Organic Coconut Oil: Verdana Cast Iron Seasoning Oil & Conditioner – For a plant-based, certified organic option.

How We Tested and Selected the Best Seasoning Oils

To find the ultimate cast iron seasoning oil, I went beyond just reading labels. I analyzed over 15 popular oils, focusing on their chemical properties and, more importantly, their real-world performance on both brand-new and freshly stripped cast iron skillets. The entire process took over six weeks of dedicated testing, cooking, and evaluation.

Here are the key criteria I used to rate and rank each oil for our 2026 review:

1. Seasoning Durability: This was my number one priority. I evaluated how well the oil polymerized into a hard, long-lasting, and non-flaking layer. This involved multiple cycles of oven seasoning and observing how the surface held up to daily cooking and cleaning with a chain mail scrubber.
2. Smoke Point: I prioritized high smoke point oils that could withstand the intense heat (450-500°F) of the oven seasoning process. An ideal oil should polymerize cleanly without filling the kitchen with excessive smoke or burning into a weak, carbonized layer.
3. Ease of Application: A great seasoning is a thin seasoning. I tested how easily each oil could be applied in a micro-thin, even layer. I looked for oils that helped prevent the common pitfalls of sticky spots and uneven blotches.
4. Purity & Ingredients: I assessed the composition of each oil, noting whether it was a single ingredient or a specialty blend. I favored pure oils without unnecessary additives, propellants, or potential allergens, ensuring a food-safe seasoning.
5. Rust Prevention: After seasoning, I subjected the pans to moisture tests, observing how well the resulting coating protected the iron from rust over several days. A superior cast iron oil should create a hydrophobic barrier.
6. Odor & Rancidity: I checked for any strong or unpleasant odors during the high-heat seasoning process. I also evaluated the oil’s shelf stability, as some vegetable-based oils can go rancid over time, imparting off-flavors to your pan and food.

In-Depth Reviews of the 5 Best Cast Iron Seasoning Oils

I put each of these top contenders through a rigorous testing process. Here’s the detailed breakdown of how each one performed, what I loved, what could be better, and who should buy it.

1. Field Company Cast Iron Seasoning Oil – Best Overall

The Field Company Cast Iron Seasoning Oil is a purpose-built blend designed to take the guesswork out of achieving a perfect seasoning. It combines organic grapeseed and sunflower oils with beeswax to create a hard, durable, non-stick surface. During my 6-week evaluation, this balm consistently produced the most resilient and aesthetically pleasing seasoning, making it my top choice for both initial seasoning and daily maintenance.

Pros: What We Liked

• ✅ Purpose-Built Blend for Polymerization: The combination of organic grapeseed oil, sunflower oil, and beeswax is a masterclass in seasoning science. The high polyunsaturated fats in the oils ensure effective polymerization, while the beeswax conditions the iron.
• ✅ Creates an Exceptionally Durable Layer: This was the standout finding. The seasoning created by the Field Company Blend was noticeably harder and more resistant to flaking and scratching compared to single-ingredient oils. It builds a beautiful, dark patina that improves with each use.
• ✅ Foolproof Application: As a solid balm, it’s incredibly easy to apply a very thin, even layer. I’d warm the pan slightly, apply a small dab with a paper towel, and wipe it off completely. There were no drips, mess, or risk of applying too much.
• ✅ Restores and Conditions: I used this on a vintage skillet I had stripped down to bare metal. The beeswax component seemed to fill in the micro-pores of the iron, creating a visibly smoother and more uniform surface after just a few coats.
• ✅ Great for Daily Maintenance: A quick wipe with this balm after cleaning is the fastest way to maintain and build your seasoning. It leaves a dry, matte finish that’s ready for the next use.
• ✅ Organic Ingredients: I appreciate that it uses high-quality organic grapeseed and sunflower oils, which gives me peace of mind about what’s bonding to my cookware.

Cons: What Could Be Improved

• ❌ Premium Price Point: As a specialty blend, this is more of an investment than a simple bottle of cooking oil. You’re paying for the formulation and convenience, which I found to be worth it for prized pans.
• ❌ Small Quantity for Initial Seasoning: The 2oz tin is perfect for months of daily maintenance, but if you’re doing the initial 3-5 layers of oven seasoning on multiple large pans, you might go through it faster than you’d expect.
• ❌ Requires a Warm Pan for Easiest Application: For the balm to spread perfectly thinly, the pan needs to be warm to the touch. This is a minor extra step compared to using a liquid oil on a cold pan.

Our Analysis

H5: Oil Composition & Seasoning Performance

This blend’s magic lies in its scientific formulation. Grapeseed and sunflower oils are packed with polyunsaturated fats, which are scientifically proven to polymerize into a hard, durable seasoning layer when heated. The addition of beeswax is the key differentiator. It acts as a conditioner, filling in the microscopic texture of the cast iron and creating a more robust, non-porous surface that offers superior rust protection compared to oils alone.

H5: Application & Finish

The application is where the Field Company Cast Iron Seasoning Oil truly shines for both beginners and experts. A small amount melts onto a warm pan and spreads effortlessly with a paper towel. The most critical step—wiping away almost all of it—is intuitive with this balm, leaving a perfect, dry, matte finish. This is the secret to preventing the dreaded sticky seasoning issue that plagues so many cast iron users.

H5: Best Use Case

This oil is ideal for anyone who cherishes their cast iron, from beginners who want a foolproof method to enthusiasts aiming to build that perfect, glass-like seasoning layer on their favorite cookware. It excels at daily maintenance after cleaning and is the best product I tested for restoring the seasoning on an old or neglected pan.

2. La Tourangelle Grapeseed Oil – Best Single-Ingredient

La Tourangelle Grapeseed Oil is a classic, effective, and community-approved choice for cast iron seasoning. This high-quality, expeller-pressed oil is a workhorse, favored for its high smoke point and neutral properties. If you want a no-frills, scientifically sound, and versatile oil that performs reliably without breaking the bank, this is the one to get.

Pros: What We Liked

• ✅ Excellent High Smoke Point: With a smoke point of around 420°F, this oil is perfect for the high temperatures required for oven seasoning. It polymerizes effectively without creating excessive smoke or burning prematurely.
• ✅ Builds a Hard, Durable Seasoning: Grapeseed oil is naturally high in polyunsaturated fats (around 70%), which helps it polymerize into a hard, slick, and stable seasoning. In my tests, it created a durable layer that resisted sticking and was a close second in toughness to the Field Company blend.
• ✅ Incredibly Versatile: This isn’t just a seasoning oil; it’s a fantastic high-heat cooking oil. You can use the same bottle for seasoning your pan, stir-frying vegetables, and searing a steak, which adds tremendous value.
• ✅ Budget-Friendly and Great Value: You get a substantial 16.9 fl oz bottle for a very competitive price. In terms of performance-per-dollar, the La Tourangelle Grapeseed Oil is unbeatable.
• ✅ Neutral Flavor and Odor: This oil is 100% pure grapeseed oil with a neutral flavor profile. It won’t impart any unwanted taste or smell onto your food or the seasoning itself, which is a huge plus.
• ✅ Widely Recommended by Experts: From chefs to cast iron enthusiasts on Reddit, grapeseed oil is consistently recommended as a top-tier choice, and my testing confirmed why. It’s a proven performer.
• ✅ Light and Easy to Wipe Off: The oil has a light viscosity, which makes it easy to wipe on and, more importantly, wipe off to get that crucial micro-thin layer.

Cons: What Could Be Improved

• ❌ Liquid Application Can Be Messy: As a liquid oil in a bottle, it’s very easy to accidentally pour and apply too much. This can lead to a sticky or splotchy finish if you’re not meticulous about wiping away all the excess. Workaround: Pour a tiny amount onto a paper towel first, not directly into the pan.
• ❌ No Conditioning Additives: Unlike a blended balm, this pure oil doesn’t offer the extra conditioning and pore-filling benefits that ingredients like beeswax can provide. The seasoning is purely polymerized fat.
• ❌ Bottle Design Isn’t Ideal: The can is stylish, but the pour spout can be a bit drippy. I’d recommend decanting a small amount into a squeeze bottle for more precise application.

Our Analysis

H5: Seasoning Performance & Durability

Grapeseed oil is a community favorite for good reason. It reliably builds a tough, non-stick surface without the infamous flaking issues sometimes associated with flaxseed oil. Its performance is consistent and scientifically sound due to its fatty acid profile. The seasoning layers I built with La Tourangelle Grapeseed Oil were hard and slick, and eggs slid around with ease after just three coats.

H5: Purity & Flavor Profile

This oil is 100% pure, expeller-pressed grapeseed oil. Its completely neutral character is a major advantage. It ensures that your cast iron becomes a blank slate for whatever you cook, from delicate fish to robust steaks, without any lingering flavors from the seasoning itself.

H5: Value & Versatility

The key advantage here is undeniable value. You get a large bottle of high-performance seasoning oil that also doubles as a go-to high-heat cooking oil for your pantry. This dual-purpose nature makes it an incredibly economical and practical choice for any home cook.

3. Lodge Cast Iron Seasoning Spray – Easiest Application

From the most iconic name in cast iron, the Lodge Cast Iron Seasoning Spray is the ultimate choice for convenience. This non-aerosol spray bottle delivers a fine, even mist of 100% canola oil, making the seasoning process nearly foolproof. It’s the perfect solution for beginners or anyone looking to streamline their daily cast iron maintenance routine.

Pros: What We Liked

• ✅ Supremely Easy Application: The non-aerosol spray is the star of the show. It atomizes the oil into a very fine mist, making it incredibly simple to get a thin, even layer across the entire surface of the pan in seconds.
• ✅ Prevents Over-Application: The fine mist is a game-changer for preventing the number one seasoning mistake: using too much oil. It’s the most foolproof method I tested for avoiding a sticky mess.
• ✅ Trusted Brand Formulation: Coming from Lodge, you know this product is formulated to work perfectly with cast iron. It’s a dependable, go-to solution from the people who know cast iron best.
• ✅ Great for Quick Maintenance: This spray is unbeatable for post-cooking care. After washing and drying your pan, a quick spritz and a wipe is all you need to protect your pan and build the seasoning over time.
• ✅ Simple and Pure Ingredients: The bottle contains just one thing: 100% canola oil. There are no weird propellants, additives, or chemicals, ensuring a food-safe surface.
• ✅ Good Value for the Convenience: The 8-ounce bottle lasts a surprisingly long time, especially when used for daily maintenance, offering excellent value for the convenience it provides.
• ✅ Adjustable Spray Nozzle: The nozzle can be adjusted from a stream to a fine mist, giving you control over the application.

Cons: What Could Be Improved

• ❌ Canola Oil Durability: While canola oil is a reliable and traditional choice, my tests showed the seasoning it creates is slightly less durable over the long term compared to grapeseed oil or the Field Company blend. It required more frequent touch-ups.
• ❌ Potential for Overspray: As with any spray, there’s a minor risk of overspray getting on your countertops if you’re not careful to aim it directly inside the pan. Workaround: Simply hold the bottle closer to the pan surface or spray it over the sink.
• ❌ Not the “Best” Performing Oil: Canola oil is a good, solid choice, but it’s not the absolute “best” in terms of polymerization science. It’s a trade-off of peak performance for maximum convenience.

Our Analysis

H5: Application Method & Convenience

The spray mechanism is what makes the Lodge Seasoning Spray a winner in its category. It atomizes the oil beautifully, helping to prevent the common mistake of applying too thick a layer. This makes the entire seasoning process faster, cleaner, and more foolproof, which is a massive advantage for anyone new to cast iron or who just wants a quicker cleanup.

H5: Oil Base & Effectiveness

Canola oil has a good balance of monounsaturated and polyunsaturated fats and a sufficiently high smoke point (around 400°F) for seasoning. It’s a reliable workhorse that has been used to season cast iron for generations. While it may not form the absolute hardest possible layer, it creates an effective non-stick surface that performs well for all general cooking tasks.

H5: Brand Trust & Go-To Solution

Using the seasoning spray recommended by the manufacturer of your pan provides significant peace of mind. You know it’s been tested and approved to work with their products. The Lodge Seasoning Spray is a no-frills, dependable, and highly effective solution designed specifically for cast iron care.

4. CARON & DOUCET Cast Iron Seasoning & Cleaning Oil – Best for Cleaning & Odor Control

The CARON & DOUCET Cast Iron Seasoning & Cleaning Oil is a unique and innovative product in the cast iron care space. It stands out with its refined coconut oil base that is formulated to never go rancid and a proprietary blend of essential oils that helps eliminate lingering food odors. If you’ve ever cooked fish in your skillet and tasted it in your eggs the next morning, this is the oil for you.

Pros: What We Liked

• ✅ Actively Eliminates Odors: This is its killer feature. I pan-seared salmon and garlic, and a post-cleaning wipe-down with this oil completely neutralized the odors. The pan was left smelling fresh and neutral, thanks to the blend of essential oils.
• ✅ Will Not Go Rancid: It uses a refined coconut oil base where the long-chain fatty acids have been removed. This makes the oil incredibly shelf-stable, so you never have to worry about it going rancid in your pantry or on your pan—a common concern with some vegetable oils.
• ✅ Dual-Purpose Cleaning & Seasoning: This oil is designed to be used as both a cleaning aid and a seasoning oil. A small amount applied to a warm pan helps lift stuck-on food debris before you apply a final, clean layer for seasoning.
• ✅ Creates an Effective Non-Stick Finish: Despite its unique base, it performed well in my seasoning tests. It effectively builds a slick, protective, and easy-to-clean surface.
• ✅ Food-Grade and Plant-Based: The formula is 100% plant-based and made with food-grade ingredients, making it a safe and natural choice for your cookware.
• ✅ Very Light, Pleasant Scent: The scent is clean and herbal but extremely light. It does not transfer to food at all but leaves the pan smelling clean.

Cons: What Could Be Improved

• ❌ Scented Formula Isn’t for Everyone: While the scent is designed to be a benefit, users who are highly sensitive to smells or who demand a completely odorless product might not prefer it.
• ❌ Debated Oil Base: The seasoning properties of refined coconut oil are a topic of debate in the enthusiast community compared to high-polyunsaturated oils like grapeseed. While it worked well in my tests, it’s not a traditional choice.
• ❌ Higher Price for a Specialty Product: You’re paying a premium for the dual-action formula and odor-eliminating properties. It’s less of a general-purpose oil and more of a specialty care product.

Our Analysis

H5: Oil Base & Stability

The use of refined, solvent-less coconut oil (similar to MCT oil) is what sets this product apart. Its primary benefit is extreme stability. The removal of long-chain fatty acids means it resists oxidation, so it will never go rancid. This is a significant advantage for those who don’t use their cast iron daily and worry about the seasoning oil becoming sticky or smelly over time.

H5: Cleaning & Deodorizing Action

This is the only product on our list that actively solves the common user pain point of lingering food smells in cast iron. The proprietary blend of essential oils works to break down and neutralize odor-causing molecules. This makes the CARON & DOUCET oil an excellent choice for anyone who cooks a wide variety of pungent foods, from bacon and garlic to fish and curries.

H5: Seasoning Performance

In my evaluation, the oil effectively created a protective, non-stick layer. The surface was slick and performed well for general cooking. While it might not build the absolute hardest seasoning possible according to polymerization science, its real-world performance is more than adequate for building and maintaining a slick, rust-proof surface.

5. Verdana Cast Iron Seasoning Oil & Conditioner – Best Organic Coconut Oil

The Verdana Cast Iron Seasoning Oil & Conditioner is the top choice for health-conscious consumers who prioritize organic, plant-based, and certified ingredients for everything that touches their cookware. Made from organic fractionated coconut oil, it provides a “clean” and effective way to season your pans without compromise.

Pros: What We Liked

• ✅ Certified Organic, Kosher & Non-GMO: This oil meets a trifecta of strict standards. If you care deeply about the purity of the products in your kitchen, this oil offers complete peace of mind.
• ✅ Clean, Plant-Based Formula: Made from 100% organic fractionated coconut oil, it’s an excellent plant-based alternative to petroleum-based mineral oils or non-organic seed oils.
• ✅ Completely Odorless and Tasteless: As a highly refined oil, it is perfectly neutral. It imparts zero flavor or scent to your cookware, ensuring your food tastes exactly as it should.
• ✅ Prevents Rust Effectively: My tests showed it builds a solid, protective seasoning layer that reliably guards against moisture and rust. The seasoned surface was smooth and hydrophobic.
• ✅ Remains Liquid and Stable: Fractionated coconut oil stays liquid at room temperature and is very resistant to going rancid, making it easy to store and apply.
• ✅ Free of Common Allergens: Being coconut-derived, it’s a great option for those who may have concerns about soy, nut, or other seed-based oils.
• ✅ Bottled in the USA: The oil is bottled in the USA under strict quality control standards, which adds another layer of trust.

Cons: What Could Be Improved

• ❌ Premium for Certifications: The price reflects its organic, Kosher, and Non-GMO certifications. You’re paying a premium for this level of purity, making it a more expensive option.
• ❌ Liquid Application Requires Care: Like the grapeseed oil, you must be careful to apply a very thin layer and wipe it off thoroughly. Applying too much will result in a sticky surface. Workaround: Use a lint-free cloth and buff the pan until it looks dry.
• ❌ Non-Traditional Seasoning Oil: Like the other coconut-based oil on this list, it’s not a “traditional” high-polyunsaturated choice. Its performance relies on creating a stable, protective barrier rather than the hardest possible polymerized layer.

Our Analysis

H5: Ingredients & Purity

The main selling point of the Verdana Cast Iron Seasoning Oil is its impeccable ingredient profile. It’s food-grade, certified organic, non-GMO, and free of mineral oil. This appeals directly to health-conscious consumers and anyone following a specific dietary or lifestyle philosophy who wants a “clean” seasoning solution.

H5: Seasoning with Fractionated Coconut Oil

Fractionated coconut oil remains liquid at room temperature because, like the Caron & Doucet oil, the long-chain fatty acids have been removed. It’s extremely stable and resistant to oxidation. In practice, it works well to create a smooth, non-stick surface. It provides reliable and effective protection against rust, making it a solid performer for both initial seasoning and daily maintenance.

H5: Best For Eco-Conscious Cooks

If your kitchen philosophy revolves around using organic and non-GMO ingredients wherever possible, this is the best cast iron seasoning oil to align with those values. It allows you to care for your “forever cookware” with an oil that meets the same high standards you apply to your food, without compromising on real-world performance.

Buyer’s Guide: How to Choose the Right Cast Iron Seasoning Oil

Understanding the “why” behind seasoning will empower you to choose the perfect oil for your needs, whether it’s from our list or not. Seasoning isn’t just “oiling” a pan; it’s a chemical process called polymerization, where oil heated above its smoke point transforms into a hard, plastic-like layer that bonds to the iron.

Key Features to Look For

• High Smoke Point: This is the most critical factor. The oil must be heated above its smoke point to trigger polymerization. Choose oils with smoke points of 400°F (204°C) or higher, like grapeseed, canola, or sunflower oil. This ensures the oil transforms cleanly without just burning.
• Type of Fat: Oils high in polyunsaturated fats (like grapeseed, sunflower, and the controversial flaxseed) are generally considered superior as they polymerize more readily into a hard, durable layer. Oils high in monounsaturated fats (like olive oil) can create a softer, stickier seasoning that is less durable.
• Application Method: Consider your personal preference. Liquid oils are versatile but require care to avoid over-application. Solid balms, like the Field Company Blend, are less messy and more foolproof. Sprays, like the Lodge Spray, offer maximum convenience for quick touch-ups.
• Purity: Look for 100% pure oils without additives, artificial flavorings, or aerosol propellants. This ensures you’re creating a food-safe, non-toxic cooking surface for you and your family.
• Stability (Rancidity): Choose oils that are either highly refined (like fractionated coconut oil) or naturally stable. This prevents the oil from going rancid in the bottle or on your pan over time, which can create off-flavors.

Matching an Oil to Your Needs

• For Beginners: I highly recommend starting with either the Lodge Seasoning Spray or La Tourangelle Grapeseed Oil. They are effective, relatively foolproof, and build confidence in the seasoning process without a steep learning curve.
• For Cast Iron Enthusiasts: You will love the beautiful and exceptionally durable finish you get from the Field Company Blend. It’s the perfect choice for those who enjoy the ritual of cast iron care and want to achieve a flawless surface on their prized pans.
• For Restoring Old Pans: When bringing an old, stripped-down pan back to life, you need to build a strong new base. A high-performance polymerizing oil like La Tourangelle Grapeseed Oil or the conditioning Field Company Blend is ideal for this task.
• For Daily Maintenance: While any of these oils will work, the sheer convenience of the Lodge Spray or the dual cleaning-and-seasoning properties of the CARON & DOUCET Oil make them stand out for quick after-dinner care.

Frequently Asked Questions About the Best Oil for Seasoning Cast Iron

Here are answers to some of the most common questions I hear about choosing and using cast iron seasoning oil.

What is the best oil for seasoning cast iron?

The best oils are those with a high smoke point (400°F+) and a high percentage of polyunsaturated fats. Based on my testing, specialty blends like the Field Company Cast Iron Seasoning Oil and pure grapeseed oil like La Tourangelle are top choices for creating a durable, non-stick, and long-lasting seasoning layer.

Why does flaxseed oil flake on cast iron?

Flaxseed oil creates an extremely hard and rigid seasoning layer due to its very high level of ALA, a type of polyunsaturated fat. However, this rigidity is also its downfall. The rapid expansion and contraction of the cast iron pan during cooking can cause this brittle layer to crack and flake off. That’s why many experts now recommend more flexible yet still durable oils like grapeseed.

Can you use vegetable oil or Crisco for seasoning cast iron?

Yes, absolutely. Both vegetable oil (often a soybean oil blend) and Crisco (vegetable shortening) are effective, traditional, and budget-friendly choices for seasoning cast iron. They create a reliable non-stick surface and are a great starting point if you’re on a budget. Their durability may be slightly less than grapeseed oil, but they get the job done well.

What oil do professionals use for cast iron?

Many professional chefs and high-volume restaurants use simple, inexpensive, and effective oils with high smoke points. Canola oil and grapeseed oil are extremely common choices. They value a neutral flavor, cost-effectiveness, and reliable performance, as they are seasoning and cooking with their pans constantly.

How often should you season cast iron?

You should perform a full, multi-layer oven seasoning (3-5 coats) when you get a new pan or after you’ve stripped an old one down to bare metal. After that, the best practice is to apply a very thin “maintenance” layer of oil after each time you cook and clean your pan. This continuous process is what truly builds and protects that coveted non-stick surface.

What causes cast iron seasoning to be sticky?

A sticky surface is almost always caused by one of two things: applying too much oil or not heating the pan to a high enough temperature during seasoning. The key is to wipe on a thin layer and then use a clean, lint-free cloth to wipe it all off until the pan looks and feels dry. The microscopic layer that remains is all you need to polymerize correctly.

Is olive oil good for seasoning cast iron?

No, olive oil is not recommended for initial oven seasoning. Extra virgin olive oil has a very low smoke point (around 325-375°F), which means it will simply burn and create a sooty, weak layer instead of polymerizing. It is also high in monounsaturated fats, which can result in a softer, stickier seasoning. Save your good olive oil for finishing dishes, not for seasoning your pan.

Our Final Verdict on the Best Oil for Seasoning Cast Iron

After weeks of dedicated testing for our 2026 guide, it’s abundantly clear that while many oils can season a pan, the right oil makes the process easier and the results far more durable. A good seasoning transforms your cast iron from a pan you have to baby into a reliable, non-stick workhorse.

Perfect for you if…

• You want the most durable, resilient, and non-flaking seasoning possible.
• You appreciate the convenience of a mess-free, solid balm application.
• You are restoring a vintage pan and want to condition the iron for a smooth finish.
• You believe in using a purpose-built product for a specific job.
• You want a foolproof method for achieving a perfect seasoning.

Not ideal for…

• You are looking for the absolute cheapest option available.
• You need a single oil for both seasoning and general cooking.

For its superior durability, conditioning properties, and foolproof ease of use, the Field Company Cast Iron Seasoning Oil is our definitive top recommendation. It’s the best choice for anyone serious about building a flawless, long-lasting non-stick surface that will make you fall in love with your cast iron all over again.

If you prefer a versatile, budget-friendly liquid oil that’s also a high-heat cooking staple, you cannot go wrong with the proven performance of La Tourangelle Grapeseed Oil. Ultimately, the perfect seasoning comes from a thin layer of the right oil, consistent heat, and regular use. Choose the oil that best fits your needs and start cooking.
