You'll ❤️ Cooking Corned Beef in Crock Pot
"So I came up with this corned beef recipe slow cooker version on the fly as an attempt to use up stuff in my freezer and fridge! It was simple and delicious - my favorite kind of recipe." -Kori 🙂
Whenever I think of cabbage I think of corned beef! I just happened to have a corned beef brisket in the freezer, as well as a bag of frozen pearl onions that I really needed to cook, and cabbage! Voila!
From there a recipe was created...I LOVE trying to make up recipes from things that need to be eaten up or they'll be wasted! It's like a game.
Easy
Only five ingredients! It's so easy cooking corned beef in crock pot! You really just layer the ingredients, turn it on low, and forget about it for 8 to 8 hours. Nice!
Low Carb and Keto Friendly
Crockpot corned beef and cabbage is a low-carb and keto-friendly recipe. The nutritional analysis below includes a small portion of carrots and a few onions. If you are concerned, you can choose not to eat the onions and carrots, and leave them for the non-low carb/keto followers in your house (like I do)! 🙂
Many (if not most) of my recipes are made with not only low carb and keto followers in mind, but also those NOT following a low carb or keto diet. This is because a normal family is not all following the same diet, right?
Having a flexible recipe that can serve everyone in your house, or any of your guests is the best kind of recipe. It makes life much easier that way!
Instant Pot or Slow Cooker
You can make this corned beef recipe in either a slow cooker or in your instant pot. Both are easy, but I will be honest and say that the crockpot method is the easiest. It is hands-off and has fewer steps. I have included instructions for both methods below.
Make-Ahead
I often will make this recipe ahead of time by placing everything in the slow cooker and getting it ready to cook (but don't actually cook). I then cover and refrigerate until I am ready to make it during the week. It makes it super easy to make a delicious dinner during the week. Just pull it out of the fridge and turn it on Low. Yay!
How To Serve It
- Serve with the creamy dijon mustard sauce (recipe below). You won't regret it - it's delicious!
- If you're going Irish serve with a soda bread or other crusty bread. Biscuits, breadsticks, and beer bread go well with this recipe.
- Slow cooker corned beef and cabbage goes 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!

FAQ's
Is corned beef and cabbage Irish?
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!
Can I add potatoes to corned beef and cabbage?
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.
Do you rinse corned beef before cooking?
In this recipe, we recommend that you rinse the corned beef before adding to the pot.
Is corned beef and beef brisket the same thing?
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.
