Ingredients

Scale
  • 34 pounds corned beef brisket, with spice packet included
  • 4 cups beef broth or water
  • 45 medium carrots, peeled and cut into chunks
  • 34 medium potatoes, quartered (Russets or Yukon Gold)
  • 1 large onion, quartered
  • 2 cloves garlic, smashed
  • 1 bay leaf
  • Fresh thyme sprigs (optional)
  • 1 cup Guinness stout
  • 1/4 cup brown sugar, packed
  • 2 tablespoons Dijon mustard
  • 1 tablespoon apple cider vinegar
  • 1 teaspoon Worcestershire sauce
  • Pinch of black pepper

Instructions

  1. Peel and chunk the carrots and potatoes. Quarter the onion and smash the garlic cloves. Set aside.
  2. Lay the corned beef brisket fat-side up in the slow cooker. Pour in the beef broth or water, then add the spice packet that comes with the brisket. Scatter the carrots, potatoes, onion, garlic, bay leaf, and thyme sprigs around the meat.
  3. Cover and cook on low for about 8 hours until the meat is fork-tender. Check for tenderness around 7.5 hours and cook an additional 30 minutes if needed.
  4. While the meat finishes cooking, whisk together Guinness, brown sugar, Dijon mustard, apple cider vinegar, Worcestershire sauce, and black pepper in a bowl until smooth.
  5. Carefully remove the brisket from the slow cooker and place it on a baking sheet lined with foil. Brush generously with the Guinness glaze.
  6. Set your oven to broil and broil the glazed brisket for 5-7 minutes until the glaze caramelizes and bubbles, watching closely to avoid burning.
  7. Let the corned beef rest for about 10 minutes before slicing against the grain into thick, juicy slices.
  8. Serve slices with the slow-cooked vegetables and drizzle any remaining glaze on top.

Notes

Rest the meat before slicing to keep it juicy. Add a splash of fresh lemon juice to the glaze before broiling for extra brightness. Save some cooking broth to serve as a dipping sauce. Use fat-side up for better flavor and tenderness. For gluten-free, use gluten-free stout or substitute with beef broth and balsamic vinegar in the glaze.
