Cooking corned beef takes patience as it’s a tough cut of meat that benefits from a lengthy cook time. Here’s how long you should cook it:

Stovetop Cooking

For stovetop cooking, plan on at least three hours for a three-pound corned beef. Simmer it over low heat until it’s tender and cooked through.

Slow Cooker Cooking

For slow cooker cooking, plan on eight to 10 hours for a three- to four-pound cut of corned beef. Cook it on low heat to achieve tender and flavorful results.

Instant Pot Cooking

If you’re using an instant pot, plan on cooking your corned beef on high pressure for 90 minutes, followed by a natural release of at least 15 minutes. For larger cuts, add an additional 15 minutes of cook time per pound. Alternatively, you can use an instant pot corned beef recipe for more precise instructions.

Avoid These 5 Mistakes During Cooking Corned Beef

To ensure perfect results, avoid these common mistakes when cooking corned beef:

  1. Not Cooking the Meat Long Enough: Don’t rush the cooking process or the meat will be tough and chewy.
  2. Using High Heat: Don’t use high heat when cooking corned beef. It will cause the meat to toughen and dry out.
  3. Cutting Against the Grain: Always slice corned beef against the grain to ensure tender and juicy slices.
  4. Not Letting it Rest: Let the corned beef rest for 10-15 minutes before slicing it. This allows the juices to redistribute and the meat to become more tender.
  5. Overcooking the Vegetables: If you’re cooking cabbage with your corned beef, add it towards the end of the cooking process to avoid overcooking it.

Extra Tips for Perfect Corned Beef

Here are some additional tips to help you achieve the perfect corned beef:

  • Place corned beef fat side up: When cooking corned beef, always place it fat side up to allow the fat to melt and baste the meat as it cooks.
  • Add cabbage towards the end: If you’re cooking corned beef cabbage, add it towards the end of the cooking process to avoid overcooking it.

How do you cook corned beef so it’s tender?

To cook corned beef so it’s tender, it is best to cook it over low heat. A low, gentle simmer on the stovetop or in the slow cooker are two excellent methods for cooking up soft, tender slices of corned beef every time. It is also important to slice against the grain of the meat when you’re done cooking the corned beef, as this will produce a more tender result. Additionally, thinner slices of corned beef will be more tender than thicker slices.

How many minutes per pound do you cook corned beef?

The general rule for cooking corned beef is to allow about 45-50 minutes per pound. For example, if you have a 3-pound corned beef, it should take approximately 2.5-3.5 hours to cook. The cooking time may vary depending on the size and shape of the meat, so it’s important to check for tenderness with a fork before serving.

Can you overcook corned beef?

Yes, it is possible to overcook corned beef. When corned beef is overcooked, it can become tough, chewy, and dry. This is because corned beef is dense and can become tough when cooked for too long or at a temperature that is too low. To avoid overcooking corned beef, it is recommended to keep the temperature low and check the internal temperature of the meat.

How long does it take to cook corned beef on the stove?

To cook corned beef on the stove, place it in a stock pot and bring it to a boil. Then, cover and cook on low simmer for 2 1/2 to 3 1/2 hours until fork tender. Another source suggests cooking for approximately 3 hours or until tender. A recipe for corned beef and cabbage suggests cooking for 2 hours and 50 minutes. The USDA recommends cooking corned beef in a slow cooker for 10 to 12 hours on low or 5 to 6 hours on high.
