Tips for Perfect Corned Beef
- Always slice against the grain. This keeps the brisket tender instead of stringy.
- Don’t skip the spice packet: Those pickling spices give corned beef its signature flavor.
- Add cabbage last: Cabbage cooks quickly and can become mushy if added too early.
- Rest the meat before slicing: Let it sit for about 10 minutes so juices redistribute.
Cooking Methods
- Slow Cooker: Add the corned beef and ingredients as directed and slow cook on high for 6 to 8 hours and low for 8 to 10 hours.
- Instant Pot or Pressure Cooker Mode: Place the corned beef in the pot, set for 1 hour and 10 minutes on pressure cook mode for 2 to 3 lbs. Close the valve. Let it rest after cooking for 10 minutes before releasing the steam.
- Oven: in a covered Dutch oven, add all the ingredients and set the oven to 275 degrees for 5 hours.
- Stovetop: In a large covered deep 8-quart saucepan, add all ingredients, and simmer on low heat for 4 hours. Continue to add more beer, water, or apple juice and check to see if the liquid is evaporating.

Slow Cooker Guinness Corned Beef
Few meals feel as comforting and celebratory on Saint Patrick's Day as a slow-cooked pot of tender corned beef with cabbage, potatoes, and carrots
Prep time: 10 MinCook time: 7 HourTotal time: 7 H & 10 M
Ingredients
- 1- 4-pound or larger corned beef brisket and seasoning packet ( I prefer flat cut)
- 2/3 cup brown sugar ( I have used less before, depending on how big the roast is, use 1/4 cup for less than a 4-pound beef)
- 1 bottle stout beer or beef stock ( 12-ounce bottle)
- Optional: 1 head of cabbage, cut up, 1 cup fingerling carrots, and 4 potatoes, cut into cubes
- Refer to notes for other suggestions
Instructions
- Place the beef in the slow cooker, rub it with the sugar, then pour the beer on top.
- If using vegetables, add them on top of the meat.
- Note: We prefer to cook them in a pot just before serving on the stovetop instead of in the slow cooker.
- Cook on low for 8 to 10 hours or on high for 4 to 6 hours.
- Make sure you test this with a fork so that it pulls apart easily and is tender.
