Cooking it in the slow cooker guarantees fork-tender beef with infused flavors that melt in your mouth.

Ingredients
For the Corned Beef:
- 3-4 lbs corned beef brisket (with spice packet)
- 4 cups beef broth or water
- 1 onion, quartered
- 3 cloves garlic, minced
- 2 bay leaves
- 1 teaspoon black peppercorns
- 1 teaspoon mustard seeds
- 1 teaspoon dried thyme
For the Vegetables:
- 4 large carrots, peeled and cut into chunks
- 6 baby potatoes, halved
- 1 small head of cabbage, cut into wedges
Optional Add-Ins:
- 1 tablespoon Worcestershire sauce for extra depth
- ½ teaspoon red pepper flakes for a little heat
Instructions
Step 1: Prepare the Slow Cooker
Place the onion, garlic, bay leaves, peppercorns, and mustard seeds at the bottom of the slow cooker.
Step 2: Add the Corned Beef
Rinse the corned beef under cold water to remove excess brine, then place it fat-side up in the slow cooker. Sprinkle the spice packet over the top.
Step 3: Pour in the Liquid
Add beef broth or water until the brisket is nearly submerged. Cover and cook on LOW for 8-10 hours or HIGH for 4-5 hours.
Step 4: Add the Vegetables
With 2 hours left, add the carrots and potatoes. With 45 minutes left, add the cabbage wedges so they don’t overcook.
Step 5: Slice and Serve
Once done, remove the beef and let it rest for 10 minutes before slicing against the grain. Serve with vegetables and a ladle of the flavorful broth.

Tips & Substitutions
- Don’t Skip Rinsing: Washing off excess brine prevents the dish from becoming overly salty.
- Low and Slow is Best: Cooking on LOW for 8-10 hours results in the most tender corned beef.
- Beer for Extra Flavor: Swap 1 cup of broth for a dark stout beer like Guinness for a richer taste.
- Add More Veggies: Try adding parsnips, turnips, or celery for extra texture.
- Leftovers Make Great Sandwiches! Use leftovers for Reuben sandwiches or corned beef hash.
