Corned beef and cabbage, synonymous with American St. Patrick’s Day celebrations, is the ideal hearty meal for a chilly mid-March night. Though this slow cooker version can be completed in 4 to 4 1/2 hours on high, the brisket is best cooked low and slow.

Cooking Tips

  1. Replace the malt vinegar with apple cider vinegar to make this recipe gluten-free.
  2. While it is possible to cook vegetables in the poaching liquid, I would not recommend it. The vegetables will be very soft and may have a slight vinegar flavor. Cooking some sides in another slow cooker is a better option.
  3. You may require less fluid if you have a smaller slow cooker or piece of meat. If this happens, then you need to cut the amount of vinegar in half.
  4. The carrot and onion can be omitted, but they do add flavor to the dish. It is entirely up to you whether you want to eat these at the end or simply discard them.
  5. Allowing the meat to cool will help keep it from falling apart when cutting thin slices.

 Corned Beef Side Dishes

There are numerous side dishes that complement this corned beef. If you have an extra slow cooker or crockpot lying around, a dish like the cheesy hash brown casserole is a great one to try. Cauliflower cheese is another great side dish to serve with this. It takes some time to cook and prepare, but it is well worth it. Personally, I like to serve this delicious beef with crunchy roast potatoes and gravy.

 Corned Beef Cooking Time

Often when I choose to prepare corned beef in a slow cooker, I start very early in the morning before departing for work, then leave it to cook while I’m away at work.
