The Only 5-Ingredient Quick Pickled Red Onion Recipe You’ll Ever Need

For the perfect quick pickled red onions, you simply need one sliced red onion, a 1:1 ratio of water and vinegar, a touch of sweetener, and salt. You just combine the liquids, sweetener, and salt in a saucepan, heat the brine until everything dissolves, and pour it over the onions in a jar. It’s a foolproof method for creating delicious refrigerator pickles every time.

This is the foundational recipe, the one I come back to week after week. It’s incredibly simple and relies on the “no-canning-required” method, which makes it accessible to everyone. The key to the best texture is slicing the onion as thinly as possible. In my experience, a simple mandoline is the best tool for achieving uniform, paper-thin slices, but I’ll also share my tips for getting great results with just a sharp chef’s knife.

This recipe is more of a blueprint than a strict rule. Feel free to play with the types of vinegar or sweetener to find your perfect combination. Now, let’s get pickling!

1. Gather & Prep Your Ingredients

The essential ingredients for perfect pickled onions are a large red onion, water, vinegar (like apple cider or white), a sweetener, and fine sea salt. These five components work in harmony to create the ideal balance of tangy, sweet, and savory flavor with a crisp texture.

• Ingredients:
  • 1 large Red Onion, sliced thin (about 1/8-inch)
  • 1/2 cup Water
  • 1/2 cup Apple Cider Vinegar (or Distilled White Vinegar)
  • 2 tbsp Maple Syrup or Granulated Sugar
  • 1 tsp Fine Sea Salt

Pro Tip: For the best color and a slightly sweeter, more complex tang, use apple cider vinegar. For a sharper, more neutral pickle that lets the onion flavor shine, stick with distilled white vinegar. In my own kitchen, I often use a mix of both to get the best of both worlds!

2. Create the Perfect Tangy Brine

Making the pickling brine involves gently heating the water, vinegar, sweetener, and salt in a saucepan just until the sugar and salt have completely dissolved. The key is to create a homogenous and flavorful liquid to pour over the onions without over-boiling it.

• Step-by-Step Directions:
  1. In a small saucepan, combine the water, apple cider vinegar, maple syrup (or sugar), and salt.
  2. Heat over medium heat, stirring occasionally, just until the mixture comes to a gentle simmer and the sugar and salt are completely dissolved. You don’t need a rolling boil.
  3. Remove from heat immediately.

Lesson Learned: Don’t over-boil the brine. I learned early on that a quick simmer is all you need to dissolve the solids. Boiling it for too long can cook off some of the vinegar’s potency and result in a less tangy, less flavorful pickle.

3. Combine, Cool & Store

The final steps are to pack the sliced onions into a jar, pour the hot brine over them, let them cool to room temperature, and then store them in the refrigerator. This simple process ensures the onions become perfectly pickled, crisp, and ready to eat in under an hour.

• Step-by-Step Directions:
  1. Tightly pack the thinly sliced red onions into a pint-sized glass jar.
  2. Carefully pour the hot brine over the onions until they are fully submerged. Use a spoon to gently press the onions down to release any air bubbles.
  3. Let the jar cool on the counter for 20-30 minutes, or until it reaches room temperature.
  4. Secure the lid and transfer to the refrigerator. They are ready to eat in as little as 30 minutes, but are best after a few hours.
  5. Store in the refrigerator for up to 3 weeks.

Pro Tip: For the absolute best flavor and color, let them marinate in the fridge overnight. I’ve found that this extra time allows the brine to fully penetrate the onions, deepening the flavor and creating that signature, jaw-dropping fuchsia color.

5 Flavor Variations to Customize Your Pickled Onions

You can easily customize your pickled onions by adding whole spices, fresh herbs, or other aromatics to the jar before pouring in the brine. For a spicy kick, add sliced jalapeños and peppercorns. For a savory flavor, toss in smashed garlic and fresh dill. For a Mexican-style twist, use lime juice and oregano.

Once you’ve mastered the basic recipe, the fun truly begins. Think of the brine as a blank canvas for your culinary creativity. The capsaicin from something like a jalapeño will slowly infuse into the brine, giving a pleasant, lingering heat to every single onion slice. It’s a simple way to create complex flavors.

Here are five of my absolute favorite variations to get you started.

1. Spicy Jalapeño & Peppercorn

To make spicy pickled onions, simply add thinly sliced jalapeño and whole black peppercorns to the jar with your red onions. For an extra layer of heat, you can also toss in a pinch of red pepper flakes.

• Materials Needed:
  • Basic Pickled Red Onion Recipe (above)
  • 1/2 Jalapeño, thinly sliced
  • 1 tsp Whole Black Peppercorns
  • 1/4 tsp Red Pepper Flakes (optional, for extra heat)
• Step-by-Step Directions:
  1. Add the sliced jalapeño, peppercorns, and red pepper flakes to the jar along with the sliced red onions.
  2. Proceed with the standard recipe by pouring the hot brine over the top.

Pro Tip: For more heat, include some of the jalapeño seeds. For a milder spice that still has that great jalapeño flavor, make sure to discard all seeds before adding the slices to your jar. I personally like to live on the edge and keep a few seeds in!

2. Savory Garlic & Herb

For a wonderfully savory version, add a few lightly smashed garlic cloves and sprigs of fresh herbs like dill or thyme to the jar. This infusion creates an aromatic pickle that is perfect for sandwiches and salads.

• Materials Needed:
  • Basic Pickled Red Onion Recipe (above)
  • 2-3 Garlic Cloves, lightly smashed
  • 2 sprigs of Fresh Dill or Thyme
• Step-by-Step Directions:
  1. Place the smashed garlic cloves and fresh herb sprigs into the jar with the sliced onions.
  2. Complete the recipe by pouring the hot brine over the contents.

Pro Tip: From experience, I recommend lightly smashing the garlic cloves with the side of a knife rather than slicing them. This releases their essential oils for a deeper, more infused flavor that permeates the entire jar without becoming harsh or overpowering.

3. Mexican-Style with Lime & Oregano

To make authentic Mexican-style pickled onions, add fresh lime juice to the brine and toss dried Mexican oregano and whole cumin seeds into the jar with the onions. This version is the absolute best topping for tacos, burritos, and nachos.

• Materials Needed:
  • Basic Pickled Red Onion Recipe (above)
  • Juice of 1/2 Lime (add to the brine)
  • 1 tsp Dried Mexican Oregano
  • 1/2 tsp Whole Cumin Seeds
• Step-by-Step Directions:
  1. Add the dried oregano and cumin seeds to the jar with the sliced onions.
  2. Add the fresh lime juice to the brine mixture in the saucepan before heating.
  3. Proceed with the recipe as directed.

Lesson Learned: Using Mexican oregano makes a noticeable difference. I once substituted it with standard Mediterranean oregano and the result wasn’t the same. Mexican oregano has a more floral, citrusy, and earthy flavor, while the Mediterranean variety is more minty and savory. It’s the key to that authentic taqueria taste.

4. Sweet & Warm with Maple & Cinnamon

For a unique, warm-spiced version, add a whole cinnamon stick and a star anise pod to the jar, using maple syrup as the sweetener in your brine. This creates a sweet and fragrant pickle that pairs beautifully with rich meats and cheese boards.

• Materials Needed:
  • Basic Pickled Red Onion Recipe (using Maple Syrup)
  • 1 Cinnamon Stick
  • 1 Whole Star Anise
• Step-by-Step Directions:
  1. Break the cinnamon stick in half and add it to the jar with the star anise and sliced onions.
  2. Ensure you use maple syrup as the sweetener in the brine for the best flavor pairing.
  3. Complete the recipe as directed.

Pro Tip: This variation is absolutely incredible on a holiday charcuterie board or served alongside roasted pork or brisket. The warm spices of cinnamon and anise are a perfect counterpoint that balances the richness of fatty meats and creamy cheeses.

5. Bright & Zesty with Citrus & Ginger

To create a bright, zesty, and slightly Asian-inspired pickle, add wide strips of orange and lemon peel along with a few slices of fresh ginger to the jar. Using a neutral white vinegar allows these bright flavors to truly shine.

• Materials Needed:
  • Basic Pickled Red Onion Recipe (using White Vinegar for neutrality)
  • 2 wide strips of Orange Peel (pith removed)
  • 2 wide strips of Lemon Peel (pith removed)
  • 3 thin slices of Fresh Ginger
• Step-by-Step Directions:
  1. Use a vegetable peeler to get wide strips of citrus peel, making sure to avoid the white pith.
  2. Add the citrus peels and ginger slices to the jar with the onions.
  3. Proceed with the recipe, preferably using distilled white vinegar to let the bright citrus and ginger flavors stand out.

Pro Tip: Avoiding the white pith on the citrus peel is absolutely crucial. The pith is very bitter and can throw off the entire balance of your brine, making it unpleasant. I always take an extra moment to scrape off any pith with a paring knife to ensure a clean, zesty flavor.

FAQs About Pickled Red Onions

What are some common mistakes when pickling onions?

The most common mistakes are slicing the onions too thick, which results in a less tender pickle, and boiling the brine for too long, which can diminish its tangy flavor. Other errors include not allowing the jar to cool completely before refrigerating, which can impact the final texture, and not ensuring the onions are fully submerged in the pickling liquid, which leads to uneven pickling.

Do pickled red onions have any health benefits?

Yes, they do offer some health benefits, primarily because red onions themselves are a great source of antioxidants, Vitamin C, and prebiotic fiber, which is beneficial for gut health. While the quick-pickling process doesn’t create probiotics like traditional fermentation, it is a very low-calorie and low-fat way to add a huge amount of flavor to your meals. Using a natural sweetener like maple syrup can further enhance its profile compared to many store-bought condiments.

What kind of vinegar do you use for pickled red onions?

The best and most popular vinegars are apple cider vinegar, for a slightly sweeter and more complex flavor, and distilled white vinegar, for a cleaner, sharper, and more neutral taste. White wine vinegar also works wonderfully as a mild option. You can use a single type or create a custom blend. It is generally best to avoid very dark and powerfully flavored vinegars like balsamic or malt, as they can overwhelm the onion’s flavor and muddy its beautiful pink color.

Final Thoughts

This one simple, 10-minute recipe can fundamentally change the way you approach everyday cooking. It’s more than just a condiment; it’s a tool in your culinary arsenal that adds a pop of vibrant fuchsia color, a burst of tangy flavor, and a satisfyingly crisp texture to countless meals.
