This slow cooker corned beef and cabbage is the easiest way to get the most ultra tender corned beef out there. Cooked low and slow with cabbage, potatoes, and carrots for an authentic Irish meal, I serve mine with a creamy horseradish sauce and plenty of dark beer!

🥬 What Makes This Recipe So Good

  • This is a whole meal, cooked right in the slow cooker! Savory meat with 3 types of veggies means you don’t have to scramble for sides to pair with your entrée.
  • It’s so easy to cook corned beef in the Crockpot, and thanks to the low and slow cooking method, it comes out unbelievably tender and juicy every single time.
  • Instead of tossing everything in the slow cooker right from the beginning, we stagger the veggies, adding the potatoes & carrots after 3 hours of cooking, and adding the cabbage after 7 ½ hours. It’s ever-so-slightly more involved that way, but it keeps the vegetables from getting mushy during the cooking process. Trust me, it’s worth the effort.

🗝️ Key Ingredients

Corned Beef – You want the whole she-bang here: a full corned beef brisket. If you’re really ambitious, you can buy a beef brisket and cure it in a brine yourself, but it’s easier to just pick up a ready-to-cook corned beef brisket. Make sure it includes the spice packet!

Cabbage – Boiled cabbage is a traditional corned beef side, and cooking it right in the Crockpot makes life (and dinner) so much easier. Cabbage doesn’t take long at all to cook, so don’t add it until the last 30 minutes!

Potatoes and Carrots – Rounding out this St. Patrick’s Day feast are savory, satiating potatoes and carrots. Cooking them in the Crockpot makes them unbelievably tender, plus they absorb those rich flavors from the corned beef. If you like your veggies a little more crisp, you might prefer these oven-roasted potatoes and carrots.

👩🏼‍🍳 Chef’s Tips

  • If you don’t want a chewy, tough corned beef (uhhh, who does??) then it’s important that you make sure the brisket is fully covered by water (and beer, if you’re using that). A good rule of thumb is to cover it completely with water, then add more so that the waterline sits about an inch above the top of the brisket.
  • The creamy horseradish sauce is totally optional, but I highly recommend it! It compliments the flavors in the corned beef SO well, and I love the creaminess with the tender veggies.
  • You’ll notice there’s no salt in the ingredients list. That’s not an oversight! The spice packet is typically pretty salty, so you really don’t need to add more. Trust me.

  • Thinly slice corned beef, cutting against grain of meat, and serve immediately with potatoes, carrots, cabbage, and creamy horseradish sauce (optional). If desired, garnish with fresh parsley before serving.
  • Spice Packet: Your corned beef should come with a spice packet. Make sure you’ve got that before leaving the store!
  • Water: Make sure the brisket is fully covered with water (and beer, if using that) and then add additional water so the waterline sits roughly 1″ above the top of the brisket. It’s important that the corned beef is fully covered so it doesn’t end up tough or chewy.

      Haha, we try to be as thorough as possible! So glad you enjoyed it, Laurie! Thank you for coming back and leaving a review ☺️

  4. What if I want to put 2 corned beefs in? Roughly 2.5 lbs each? Do I follow same steps and time?

    1. Megan | 40 Aprons Team Megan | 40 Aprons Team says:

      You would likely need to cook them longer to ensure they’re both completely cooked through. Make sure you adjust the number of servings until the recipe reflects at least 5 pounds of corned beef so you’ve got enough of the other ingredients!
