Slow cooker corned beef brisket is one of those dinners that feels a little special but couldn't be easier to make. The brisket simmers low and slow in a rich, savory broth with cabbage, carrots, and onions until it's juicy, fork tender, and practically falling apart. Add a drizzle of creamy Dijon mustard sauce on top and you've got a hearty, high-protein dinner that's simple, comforting, and always worth the wait.

The backstory.

Corned beef and cabbage always feels like a little event in our house. Maybe it's the Irish roots of the dish or maybe it's just the smell of that brisket slowly simmering away all day that makes it feel special. Either way, it's the kind of dinner that pulls everyone into the kitchen asking when it'll be ready. Years ago I tried making it in the slow cooker instead of the oven and never looked back. Slow cooking a corned beef brisket just makes sense - the meat turns incredibly tender, the vegetables soak up all that flavorful broth, and dinner practically makes itself.

It's a must-make.

Some dinners just feel like comfort the minute you smell them cooking. Slow cooker corned beef brisket is definitely one of those meals.

  • Effortless and delicious. This corned beef brisket crock pot recipe uses simple ingredients and minimal prep - just layer the brisket, cabbage, carrots, and onion in the slow cooker and let everything simmer together in a rich, flavorful broth.
  • Fork tender every time. Slow cooking a corned beef brisket low and slow creates juicy, fall apart meat while the vegetables soak up all that savory flavor.
  • A hearty one pot dinner. This classic corned beef cabbage crock pot meal is packed with vegetables and high protein brisket, making it satisfying while still naturally low carb.
  • Slow cooker or Instant Pot - your call. The slow cooker gives you deep, slow-simmered flavor, but the Instant Pot works great when you need dinner on the table faster.

Any dinner that quietly simmers all day and makes the kitchen smell amazing is already halfway to being my favorite.

Let's talk texture and flavor.

Slow cooker corned beef brisket is all about rich flavor and melt-in-your-mouth texture. As the brisket slowly cooks, it becomes incredibly juicy and fork tender. The cabbage softens and absorbs the savory broth, while the carrots add a touch of natural sweetness that balances the richness of the beef. Pearl onions cook down and add depth to the broth, creating a comforting, flavorful base for the whole meal. Then that creamy Dijon mustard sauce comes in with a little tang that brightens everything up.

What you'll need.

Customize it your way.

A classic corned beef and cabbage recipe is easy to tweak depending on what you're craving.

  • Replace the water with beef broth or a bottle of stout beer such as Guinness for a richer broth.
  • Add chunks of potatoes for the classic cornbeef cabbage and potatoes combination.
  • Toss in a few cloves of garlic for extra savory flavor.
  • Add a couple bay leaves while everything simmers.
  • Turn leftovers into a cozy corned beef casserole the next day.
  • Add herbs such as rosemary, thyme, or parsley.

Flexible dietary swaps.

One of the nice things about slow cooker corned beef brisket is how flexible it can be.

  • Dairy-free: Skip the creamy Dijon mustard sauce or make it with dairy-free sour cream.
  • Lower sodium: Soak the brisket in warm water for a couple of hours before cooking to draw out some of the salt.
  • Broth swap: Use low sodium beef broth instead of water.

How to make corned beef and cabbage recipe.

This slow cooker corned beef brisket dinner is mostly hands-off once everything goes into the pot.

  1. Place the carrots and pearl onions in the bottom of the slow cooker and set the brisket on top.
  2. Arrange the cabbage wedges around the meat so the vegetables cook in the flavorful broth.
  3. Mix the Worcestershire sauce with water and pour it over the brisket. Sprinkle with pepper.
  4. Cover and cook on low for 8 to 10 hours until the brisket is fork tender and the vegetables are tender.

How to serve it.

A slow cooker corned beef brisket dinner is best served family-style with plenty of the savory broth.

  • Slice or shred the brisket and serve it alongside the cabbage, carrots, and onions.
  • Drizzle the creamy Dijon mustard sauce over the top for extra flavor. You won't regret it - it's delicious!
  • Pair with classic corned beef sides like roasted potatoes, soda bread, or crusty bread.
  • Leftovers are great in sandwiches, hash, or turned into corned beef casserole.
  • 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.

Kori's tips.

  • Rinse the brisket before cooking to remove excess salt from the brine.
  • If sodium is a concern, soak the brisket in warm water for a couple hours before cooking.
  • The creamy Dijon mustard sauce can be made ahead of time and gently reheated.
  • Cooking on low heat gives you the best juicy, fall apart brisket.

FAQs

What is the best way to store it?

Store leftover corned beef and vegetables in an airtight container in the refrigerator for up to 4 days. Keep a little broth with the meat so it stays juicy.

Can I freeze it?

Yes. Slice or shred the brisket and freeze it with some broth for up to 3 months.

What's the best way to reheat it?

The best way to reheat corned beef and cabbage is gently with a little of the cooking broth to keep everything juicy. Place the brisket and vegetables in a skillet or saucepan, add a few spoonfuls of broth, cover, and warm over medium-low heat until heated through. You can also reheat it in the microwave in short intervals, covered, with a splash of broth to prevent the meat from drying out.

Do you rinse corned beef before cooking?

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.

Can I make corned beef and cabbage in the Instant Pot instead?

Yes! If you want a faster option, this corned beef and cabbage recipe can be made in the Instant Pot. I've included the instructions for the Instant Pot in the recipe below.

Ingredients
  

Corned Beef

  • 1 cup frozen pearl onions
  • 2 to 3 cups carrots (peeled and cut into 1 to 2" pieces)
  • 3 pound corned beef brisket (rinse the brisket and discard the spice packet)
  • ½ to 1 cabbage, sliced into wedges (depending upon the size of your crock pot)
  • 1 tablespoon worcestershire
  • water ½ cup slow cooker or 1 cup Instant Pot (you can also use beer or beef broth!)
  • ½ teaspoon pepper

Creamy Dijon Mustard Sauce (Optional)

  • ¼ cup mayonnaise
  • ¼ cup sour cream
  • 1 teaspoon lemon juice
  • 2 tablespoons grainy dijon mustard
  • ⅛ teaspoon paprika
  • Salt and pepper to taste

Instructions
 

Corned Beef in Crock Pot

  • Rinse corned beef in water and throw the seasoning packet away. Add carrots and onions to the bottom of a slow cooker that has been sprayed with nonstick spray or coated with oil/butter. Place roast on top of vegetables. Place cabbage around the corned beef brisket.
  • Mix water and worcestershire and pour of top of the roast. Sprinkle with pepper. Cook on low for 8 to 10 hours until the brisket and vegetables are tender. Serve with optional creamy dijon mustard sauce for a tasty twist.

Corned Beef in Instant Pot

  • Rinse the beef brisket and place 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 pound roast would take around 75 minutes, a 4 pound roast about 100 minutes. Once complete release pressure naturally.
  • Remove roast, leaving juices in pot, and set aside. Add cabbage, carrots, onions to the pot. Pressure cook on high for 4 minutes. Manually release pressure after 10 minutes.

Creamy Dijon Mustard Sauce

  • Mix all ingredients in a microwave-safe bowl. When ready to serve over corned beef and cabbage, warm on 50% power in your microwave. If you prefer runnier sauce add additional sour cream. Season with salt and pepper to taste.

Kori's Tips

  • Don't miss all of our helpful hints, substitution ideas, cooking tips, and other delicious recipes that can be found in our post. Check it out!
  • TIPS: The creamy dijon mustard sauce can be made well in advance. The sauce is great over chicken, pork, and fish. It also makes an easy hollandaise sauce too!
  • NOTES:
    • The sodium content in this recipe is challenging to calculate accurately since corned beef is salt-brined. The salt is infused throughout the entire brisket, making it difficult to determine exactly how much remains after cooking. If you are concerned about sodium content, soak the brisket in warm water for a couple of hours to draw out excess salt. Keep in mind that this will also draw out some of the flavors as well. In this case, you might consider using the flavor packet.

    Hello, I was just wondering where all that sodium (2828mg) comes from? I'm hoping that was just a typing error?

      I added some notes on sodium content of corned beef in the recipe card! 🙂 It is not a typo, this number comes from our nutritional calculator, and I doubled checked that we entered in the correct ingredients. I did, however, remove the optional sauce ingredients in the calculation so that lowered sodium, fat, and calories slightly.

      The 2,800 mg of sodium is coming from the recommended serving size of 4 ounces (prior to cooking) which contains 950 mg of sodium, and based on my estimation that this recipe will actually serve 6 people, maybe 8. Because corned beef will shrink significantly during the cooking process, the actual final amount, vegetables included, will likely serve 6 to 8 people, but probably not 12 (as per the corned beef package suggestion). This is all an estimate on my part of course. The per-serving sodium content includes the liquid in the package, which is not used in this recipe. The brisket is also rinsed of all surface salt brine as well. There is no way to avoid high salt content in corned beef. You can soak it in warm water for a few hours prior which will draw out the salt, but it will also draw out the flavor.
