Ingredients
  

Corned Beef
  • 3-4 lb corned beef brisket (with spice packet if included)
  • 1 tsp freshly ground black pepper
  • 1 tbsp Dijon mustard optional
Cooking Liquid
  • 4 cups water or beef broth
Vegetable Base
  • 1 large onion cut into thick wedges
  • 3 cloves garlic finely chopped
  • 3 large carrots cut into large chunks
  • 3 medium potatoes peeled and cut into bite size pieces
Final Addition
  • 0.5 head green cabbage cut into wedges

Method
 

  1. Place onion wedges in the bottom of the slow cooker. Add the chopped garlic, carrots, and potato pieces on top to create a vegetable base.
  2. Set the corned beef brisket on top of the vegetables with the fat side facing up so the melting fat naturally bastes the meat during cooking.
  3. Sprinkle the spice packet over the brisket and add the black pepper. Spread the Dijon mustard lightly over the top if using.
  4. Pour the water or beef broth into the slow cooker so the liquid surrounds the vegetables and reaches partway up the brisket.
  5. Cover and cook on low for 8 to 9 hours or on high for 4 to 5 hours until the meat becomes very tender and a fork slides in easily.
  6. About 45 to 60 minutes before the end of cooking, add the cabbage wedges to the slow cooker so they stay tender without becoming overly soft.
  7. Remove the brisket and let it rest for about 10 minutes on a cutting board. Slice the meat against the grain into thin slices.
  8. Serve the sliced corned beef with the cooked vegetables and spoon some of the flavorful broth over the top.

Notes

Rinse the brisket briefly under cold water if you prefer a milder salt level. For extra flavor, use half beef broth and half water as the cooking liquid. Always slice the brisket against the grain to keep the texture tender and easy to chew.
