Slow cooker corned beef brisket is so good, you’ll be making it far more often than once a year.
Is there anything better than coming home to the smell of a meal that’s simmering in the crock-pot? Making corned beef in the slow cooker is so easy it practically makes itself.

Slow Cooker Corned Beef Brisket
Perfectly moist, sliceable or shreddable, slow cooker corned beef brisket is possible with just a few minutes of effort. All you have to do is place the corned beef in the crockpot, sprinkle it with seasonings and add a bit of water.
Then, just turn on the crockpot and wait. Cooking at low temperature for 8 hours yields the most tender, pull-apart forkfuls of corned beef you could hope for.
It’s great in this recipe, and you’ll find a use for the leftovers in many others.

Not sure how to cook corned beef in the slow cooker? There’s no reason to be intimidated. Cooking corned beef brisket doesn’t get any simpler than this crock-pot method!
The tender texture and meaty flavor of corned beef was always a treat for us as kids and it still feels like a special meal to me.
We like to eat our corned beef with Colcannon or roasted potatoes. If you’re lucky enough to have leftover corned beef, you’ll want to set some aside for a classic Reuben sandwich.
And speaking of Reubens, we love that flavor combination so much that we turned the famous NYC deli sandwich into this Reuben Soup.

Easy Corned Beef Recipe
- Place the corned beef in the crock-pot, fat side up. (Do not rinse first.) Sprinkle with the spice packet. Add 1 cup of water, or just enough to be about 1/2″ up the side of the roast.
- Cook on LOW for 8 hours, taking care not to overcook or the meat will begin to fall apart. (Still delicious, but not sliceable.) If you prefer your corned beef to fall apart, simply cook it a little longer.
- If desired, add cabbage to the crock-pot after about 6 hours of cooking. In the remaining 2 hours of cooking time, the cabbage will soften and cook through while also absorbing a bit of flavor from the beef.

Corned Beef in Crockpot
While you can certainly cook the corned beef on its own, we enjoy the traditional pairing of crockpot corned beef and cabbage.
If desired, you can add cabbage wedges to the crock pot after about 6 hours of cooking. In the remaining 2 hours of cooking time, the cabbage will soften and cook through while also absorbing a bit of flavor from the beef.
Slow cookers or crockpots are an appliance of which I have more than one. If you are an avid slow cooker user like I am, you might understand the need for more than one. So, let’s talk about my favorites:
First up is this 6-quart slow cooker that has a locking lid. These crockpots are fantastic for transporting foods. Mine has gone everywhere from church potlucks to barbecues, game nights to Thanksgiving dinner. However, fair warning, these slow cookers run crazy hot. Low is closer to a boil than a simmer, the warm setting actually simmers. So trust me when I say HIGH is high.
My everyday slow cooker is this 8-quart Crockpot. It’s my go-to appliance for cooking large roasts and big batches of chili. Fun fact: did you know that a full 4-quart cooker, actually cooks more slowly than a half-full 8-quart cooker?
For just cooking a few pounds of chicken to shred for enchiladas or other smaller recipes, this 3-quart version is perfect.
Thanksgiving has become a breeze since I have mastered how to hold all of the side dishes using these medium-sized round slow cookers.
If you aren’t a fan of the idea of keeping more than one slow cooker in the house, these CrockPockets are a game-changer when it comes to preparing and holding multiple dishes at the same time. They slide into a standard 6-quart crockpot, dividing it into two sections that are perfect for serving different side dishes or keeping taco fillings warm for parties.

With creamy potatoes, tender leftover meat, and savory broth, Corned Beef and Cabbage Stew is another go-to method for using cooked corned beef. I think it’s tasty enough to be worth baking corned beef the day before just for the opportunity to make this comforting stew.
Then there’s the hash I crave more than any other: Corned Beef and Red Potato Hash. This skillet-fried recipe is delicious with a fried egg on top or served just as is for breakfast, brunch or anytime you need a quick and satisfying meal.

What a brilliant idea to cook the corned beef in a slow cooker. Thank you for the addition of cabbage, too. Yummy and soooo easy.
I’m so glad you like the recipe!
What time period, in the crockpot, would I place red potatoes and carrots?
I would suggest adding them with the cabbage. Just make sure to dice them into 1-inch-sized pieces so they cook a bit more quickly.
Awesome it retained all of the moisture and flavor and melted in our mouths.
That is awesome, Jack.
Having 25 for St Patricks Day 3 large crock pots ??
That should work nicely, Marjorie.
Can I cook on high for 4 hours?
I have not tried that, Daniel. Corned beef usually does best when it is cooked low and slow.
Can I put 2 corn beefs in crockpot little over 3 lbs a piece. I have 7 quart crock pot ..
I would recommend separate crockpots, JoAnn.
Also how long would I have to cook 2 corn beef’s in crockpot on low?? Little over 3 lbs each
I would suggest putting them in separate crockpots on low for about 8 hours, JoAnn.
I have cooked 2 in the same crackpot many times, just pay closer attention and test for tenderness occasionally twards the end, I sometimes pull the smallest one out and leav the other in longer. Put small potatoes in for the last three hours, when I do this, I raise the temp to high because adding cold potatoes will lower the temperature. Patrick. Ps. The seasoning is basically pickeling spices.
I’m so glad you like it, Patrick!
Remove all that fat,add brown sugar and Guinness!Cheers!
Sounds amazing!
I love corned beef but I’m only one person. How long week l do i cook a 1 pound corned beef in the crock pot on Low?? Thanks.
Unfortunately, I don’t have the exact time for that, as I’ve never tried it myself, Holly. My guess would be about 4-5 hours on low, as a 2-3lb roast will usually be cooked in 7-8 hours on low or 3-4 hours on high.
love it
I’m happy to hear the corned beef is a win, Aaron!
Dang, I wish you would have said what kind of flavor packet I needed. I’m cooking this for the first time on Thanksgiving. I found your article informative otherwise.
The flavor packet is in the package with store-bought corned beef.
Way to salty, decided to TRUST your method and not to rinse as what other websites have recommend. Luckily, I bought two and will try again rinsing the corned beef
Corned beef is typically pretty salty, and we definitely enjoy our corned beef as written in the recipe here. Hopefully you’ll enjoy it more if you rinse before cooking.
