A comforting slow cooker corned beef recipe featuring a rich, slightly sweet Guinness glaze that makes the meat tender and flavorful. Perfect for busy days and cozy meals.

Ingredients

Scale
  • 34 pounds corned beef brisket (with spice packet included)
  • 1 cup Guinness stout (240 ml)
  • ½ cup brown sugar (100 g)
  • 2 tablespoons Dijon mustard
  • 1 tablespoon apple cider vinegar
  • 4 garlic cloves, minced
  • 2 bay leaves
  • 1 teaspoon whole black peppercorns
  • Optional vegetables for cooking: 2 large carrots, peeled and cut; 1 large onion, quartered; 2 celery stalks, chopped

Instructions

  1. Rinse the corned beef brisket under cold water to remove excess salt and spices. Pat dry with paper towels. (5 minutes)
  2. Place the optional chopped carrots, onions, and celery at the bottom of the slow cooker. (5 minutes)
  3. Place the brisket fat side up on top of the vegetables. Tuck in the bay leaves and sprinkle the whole black peppercorns evenly. (2 minutes)
  4. In a bowl, whisk together the Guinness stout, brown sugar, Dijon mustard, apple cider vinegar, and minced garlic until smooth. (5 minutes)
  5. Pour about half of the Guinness glaze over the brisket in the slow cooker. Reserve the other half for glazing later or serving. (2 minutes)
  6. Cover and cook on low for 8 to 10 hours, or on high for 4 to 5 hours until the meat is fork-tender. (8-10 hours)
  7. Carefully remove the brisket and place it on a baking sheet lined with foil. Brush the reserved glaze generously over the top. Optionally, finish under a broiler for 3-5 minutes to caramelize the glaze. (10 minutes)
  8. Allow the brisket to rest for 10 minutes before slicing against the grain into thin pieces. (10 minutes)
  9. Serve with cooked vegetables or your favorite sides. Pour any remaining glaze over the slices.

Notes

Rinse the corned beef to reduce excess salt. Cook on low for best tenderness. Optionally finish under broiler for caramelized glaze. Leftovers keep well refrigerated for 4 days or frozen for up to 3 months. Reheat gently to keep moist. Substitute Guinness with other dark beers or gluten-free alternatives. Brown sugar can be swapped with maple syrup. Add crushed red pepper flakes for a spicy kick.
