How do I cook Corned Beef in a Slow Cooker without vegetables?
No vegetables are required to cook corned beef in a slow cooker. Proceed with the recipe and omit the vegetables. The onions add quite a bit of flavor so you may want to consider keeping those. If you still choose to cook the beef without vegetables I recommend that you add the seasoning packet that comes in the corned beef package.
Slow Cooker Corned Beef FAQs
Corned beef should be cooked in a slow cooker on low for 8 to 10 hours or until it is fork tender. According to the USDA, corned beef is done when its internal temperature reaches 145 degrees F when checked with a thermometer.
Absolutely. You can add 1 to 2 lbs of potatoes that have been cut into 1 or 2u0022 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.
To control the salt level, you should rinse the corned beef. In this recipe, we recommend that you rinse the corned beef brine before adding to the pot.
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.
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!

- The sodium content is very difficult to calculate in this recipe, and there is really no way to avoid it. According to the various brands producing corned beef, a serving size is 4 ounces prior to cooking. Each 4-ounce portion has 950 mg of salt, but it also includes the liquid within the package, which won’t be used. Corned beef is salt brined, and the flavor and salt are infused throughout the entire brisket. A 3-pound (48-ounce) brisket technically serves 12 people. Like all meat, corned beef shrinks when cooked in a crockpot or Instant Pot, making that final cooked amount of beef significantly smaller. We estimate this recipe to serve 6 people, maybe 8. Because of the serving size, our nutritional analysis is displaying 2,800 mg of sodium per serving. This number is probably high, but we are unable to provide an exact estimate.
- If you are concerned about sodium content, soak the brisket in warm water for a couple of hours to draw out excess salt. Keep in mind that this will also draw out some of the flavors as well. In this case, you might consider using the flavor packet.
