Ingredients

Scale
  • 3 to 4 pounds corned beef brisket with spice packet
  • Half a medium head of cabbage, chopped into wedges
  • 4 medium carrots, peeled and cut into chunks
  • 2 medium yellow onions, quartered
  • 4 cloves garlic, smashed
  • 12 oz (355 ml) Guinness beer
  • 2 tablespoons brown sugar
  • 1 tablespoon Dijon mustard
  • 1 tablespoon apple cider vinegar
  • 2 cups (475 ml) beef broth
  • 2 bay leaves
  • 1 teaspoon whole black peppercorns
  • 1 teaspoon whole mustard seeds (optional)

Instructions

  1. Rinse the corned beef under cold water to wash away excess brine, then pat dry with paper towels. Trim any thick fat if desired.
  2. Chop the cabbage into wedges, peel and cut the carrots into large chunks, quarter the onions, and smash the garlic cloves.
  3. Place the onions, carrots, and garlic at the bottom of the slow cooker.
  4. Place the brisket fat side up on top of the vegetables. Scatter the spice packet contents, bay leaves, peppercorns, and mustard seeds over the brisket.
  5. Pour in the beef broth and Guinness beer carefully, ensuring the brisket is mostly submerged but not completely covered.
  6. Cover and cook on LOW for 8 to 10 hours, or until the meat is fork-tender.
  7. About 1 hour before serving, nestle the cabbage wedges into the slow cooker around the brisket. Recover and continue cooking until the cabbage is tender but not mushy.
  8. While the last hour cooks, whisk together the brown sugar, Dijon mustard, apple cider vinegar, and 1/4 cup (60 ml) Guinness in a small bowl until smooth.
  9. When the brisket is done, carefully transfer it to a baking sheet or dish. Brush the glaze generously over the top.
  10. Optional: place under a broiler for 3–5 minutes to caramelize the glaze, watching closely to prevent burning.
  11. Let the corned beef rest for 10 minutes before slicing against the grain into 1/4-inch (0.6 cm) thick slices.
  12. Serve with the tender cabbage, carrots, and onions spooned alongside.

Notes

Rinse the corned beef to reduce saltiness. Place brisket fat side up to baste meat during cooking. Add cabbage in the last hour to avoid mushiness. Glaze at the end to prevent burning sugars. Broil glaze for caramelization if desired. Rest meat before slicing for juiciness. For gluten-free, use gluten-free stout or beer. Can substitute Dutch oven if no slow cooker is available.
