Instructions for making corned beef in crock pot and an Instant Pot are below. Happy cooking!
Make Sauce (Optional)
Mix all the creamy sauce ingredients in a small bowl and refrigerate until ready to serve.
Rinse corned beef and throw the pickling spice packet away.
Add carrots and onions to the bottom of the crockpot that has been sprayed with nonstick spray or coated with oil or butter.
Add Corned Beef Roast to Pot
Place corned beef on top of vegetables. Place cabbage around the brisket.
Mix water and Worcestershire and pour on top of the roast. Sprinkle with pepper.
Slow cook corned beef and vegetables on low for 8 to 10 hours until the brisket and veggies are tender.
Serve sliced corned beef over vegetables and top with warmed dijon mustard sauce (see recipe card) if desired.
How To Make Instant Pot Corned Beef
Here's how to make the Instant Pot corned beef version. Don't miss the video below!
Place Corned Beef in Instant Pot
Rinse the whole brisket and throw the pickling spice packet away. Place corned beef brisket in the pressure cooker.
Pour 1 cup of water and Worcestershire, (or you could use 1 bottle of beer - any kind) over brisket. Sprinkle with pepper.
Secure lid and cook on high pressure for 25 minutes per pound. (A 3 lb roast would be 75 min, a 4 lb roast 100 min.)
Once the pressure cooking cycle is complete allow pressure to release naturally.
Remove roast, leaving juices in pot, and set aside.
Add cabbage, carrots, and onions to the pot. Pressure cook on high for 4 minutes.
Manually release pressure after 10 minutes.
🥗 How To Serve It
- Serve with the creamy dijon mustard sauce (recipe below). You won't regret it - it's delicious!
- Garnish with fresh parsley or chives.
- If you're going Irish, serve with soda bread or other crusty bread. Biscuits, breadsticks, and beer bread go well with this recipe.
- Slow cooker corned beef and cabbage go well with potatoes, mashed potatoes, and rice. Low carb keto followers use riced cauliflower or mashed cauliflower.
- A fresh side salad with a favorite salad dressing is always a nice addition. If you want a make-ahead solution try my Layered Salad - it can serve a crowd or make great lunch leftovers.
- Got leftovers? Make corned beef hash by dicing the corned beef, some potatoes, and onion. Brown the potatoes and onions in a skillet then add diced corned beef until warmed through. Serve with eggs over the top!
There are several ways you can vary or make substitutions to this slow cooker corned beef recipe. Here are some ideas:
- Use water, beef broth, or a stout beer such as Guinness for your liquid - or any combination thereof.
- Add herbs such as rosemary, thyme, or parsley.
- Use garlic if desired. I like to add whole cloves - they are delicious!
- If you have enough room in your slow cooker add potatoes. You can certainly add any favorite potato if you still have room in your slow cooker or pressure cooker. My favorite are the tiny baby potatoes.
Corned beef should be cooked in a slow cooker on low for 8 to 10 hours or until it is fork tender. According to the USDA, corned beef is done when its internal temperature reaches 145 degrees F when checked with a thermometer.
Absolutely. You can add 1 to 2 lbs of potatoes that have been cut into 1 or 2" pieces. Add to the bottom of the slow cooker with your carrots and onions.
By adding potatoes you will have less room for cabbage, however.
I found my 6 qt slow cooker too small for potatoes and cabbage, however.
To control the salt level, you should rinse the corned beef. In this recipe, we recommend that you rinse the corned beef brine before adding to the pot.
Corned beef brisket and beef brisket are not the same things. Corned beef brisket is made with a beef brisket but has been brined with special seasoning. Beef brisket has not been seasoned or brined.
Actually, there is some debate about this. Most people say that corned beef and cabbage is an Irish American recipe, and the tradition of having it on St. Patrick's Day also developed here in the U.S. Corned beef and cabbage is not as frequently served in Ireland. Sorry!
When visiting Ireland a few years ago, we specifically asked what was traditionally served on St. Patrick's Day and were told they serve a variety of dishes such as steak and Guinness pie, shepherd's pie, lamb roast, fish, and other delicious recipes!
