St. Patrick’s Day is the one day a year that many people flock to the grocery store in search of ingredients for a corned beef dinner. This slow cooker corned beef and cabbage only has a few minutes of active prep work, and produces a festive and delicious meal that the whole family will love!

What is corned beef made of?

Corned beef is a beef brisket that soaks in brine and then cures with salt and seasonings. This cut of meat has a distinctive pink color from sodium nitrate which is an ingredient in the curing process. Corned beef comes in multiple cuts, and it’s always best to cook corned beef for a long period of time so that it becomes tender. Typical cooking methods include boiling, slow cooking or oven roasting the meat.

How do you buy corned beef?

The first step to this recipe is to choose your meat. Most stores sell pre-seasoned corned beef, especially in March. There are a few different cuts of corned beef to chose from, including corned beef round roast, flat cut brisket, and point cut brisket. The round roast tends to have the least fat, but is also much more prone to drying out for that same reason.

Flat cut brisket and point cut brisket tend to be the better corned beef options. I used a flat cut brisket for these photos, as you can see by the uniform size and shape of the slices. Point cut brisket is the fattiest cut, but can also sometimes be the most tender. So it’s really up to you which cut you use!

How do you make slow cooker corned beef?

Corned beef comes pre-brined and pre-seasoned, so all you have to do is put it in a slow cooker with carrots and potatoes, then walk away. I add the cabbage during the last part of the cooking process so that it doesn’t get overly soft. Slice your beef, then serve it on a platter with the potatoes, carrots and cabbage.

Crock Pot Corned Beef Tips

  • This recipe really works best on the low heat setting. I know the temptation is there to crank up the heat and have your meal done in half the time, but you run the risk of a tough corned beef if you do that. I recommend putting your meat in the crock pot first thing in the morning to ensure perfection by dinner time.
  • The potatoes and carrots get quite soft from cooking all day in the crock pot. If you prefer your veggies on the firmer side, try adding them halfway through the cooking time.
  • Corned beef makes for great leftovers, it’s great in sandwiches, hash or in a reuben dip.
  • Be sure to slice the meat against the grain for the most tender bites of beef.

You don’t need to add any extra seasoning to your crock pot other than the packet that comes with the corned beef; the meat is plenty salty to flavor the potatoes and vegetables. However, I prefer to add a little drizzle of garlic and herb butter over the top of the veggies. It adds a nice finishing touch that you typically don’t see with corned beef meals.

  1. “pat dry with paper towels”

    It’s being placed in a crock pot almost immediately with water. Does a type of oxidation occur when dried before being placed in a crock pot.

    1. You pat it dry to remove the excess salt from the surface of the meat because corned beef can be very salty.

    I’ve been loving all of your recipes! I make corned beef and cabbage every year and this is now my favorite recipe! I also made your Irish soda bread and shamrock shakes which were a huge hit. Thank you! ☘️

  3. I followed the recipe but I’m slightly nervous the three cups of water isn’t touching the meat. I hope it will cook properly. I don’t use the crock pot often. I put the veggies in first then the meat on top. I was thinking of adding a second piece of meat since this one is only about 2.5 pounds but I’d have to stack them. My crock pots is round not oval. Does anyone else notice the water doesn’t cover the meat. Even if I double the recipe it still only calls for 3 cups of water. I liked that this recipe didn’t call for beer like many others did. Looking forward to tasting it later.

    1. The meat does not need to be completely under water, but you do want the water to at least touch the meat. This may have happened because the crock pot is too small or meat is an awkward shape. It’s ok to add more water it won’t hurt anything!

  4. Just trying your recipe for corned beef & cabbage. Hope it’s as good as it sounds. (I added one bottle of Guinness to make it a little more Irish.)

    Made this for a “day before” St Pats day dinner. Also made soda bread. The corned beef was perfect. I will make it again for sure

  6. 5 stars
    I cook this meal more than just for St. Patrick’s Day events. My Family loves it. I use Maille Mustard, Old Style Mustard and it is the BOMB! Other than that I do not change a thing. Perfect Recipe!

    1. It’s to remove the excess brine that the corned beef sits in from the package, otherwise your meat can be overly salty.

    Add veggies at 1/2 point and while meat is cooking for 3 hrs potatoes were soaking in a little of garlic with water

    Delicious! Made this a few weeks ago & it was so good I’m doing it again tomorrow for company. I use beef broth instead of water & wait on the veggies until halfway point. It’s becoming my go to recipe.

    1. Thanks so very much for sharing, did you use low sodium beef broth? Thanks for your reply in advance.
      Sincerely Mrs Alexander.

    Delicious! Used 4 cups Amber Beer instead of water. Cooked cabbage separately in pot with broth from crockpot.
    Served with Irish Soda Bread

  10. 5 stars
    Delicious! Made this for St Patrick’s Day. Added the vegetables at the 4 hour point and the cabbage at 6 hours. Used a broth instead of water and omitted salt from butter after tasting the vegetables. Only cabbage needed any additional salt.
