Ingredients

Scale
  • 34 pounds corned beef brisket (with spice packet)
  • 1 large yellow onion, peeled and quartered
  • 4 garlic cloves, peeled and smashed
  • 3 medium carrots, peeled and cut into chunks
  • 4 medium Yukon Gold or red potatoes, halved
  • 1 medium head green cabbage, cut into wedges
  • 2 bay leaves
  • 10 whole black peppercorns
  • 4 cups water or beef broth
  • 3 tablespoons Dijon mustard
  • 1 tablespoon honey or maple syrup
  • 1 teaspoon apple cider vinegar
  • Pinch of smoked paprika (optional)

Instructions

  1. Rinse and prep your corned beef: Rinse brisket under cold water to remove excess brine and pat dry with paper towels. (5 minutes)
  2. Layer the slow cooker: Place quartered onion, smashed garlic, carrots, and potatoes at the bottom of the slow cooker. (5 minutes)
  3. Add the corned beef brisket: Place fat side up on top of the veggies. Sprinkle black peppercorns and add bay leaves around the meat. Pour in enough water or beef broth to cover about two-thirds of the brisket. (3 minutes)
  4. Cook low and slow: Cover and cook on low for 7 hours. (7 hours)
  5. Add cabbage wedges: Nestle cabbage wedges around the meat and vegetables. Cover and cook on low for another 1 hour. (1 hour)
  6. Make the mustard glaze: Whisk together Dijon mustard, honey, apple cider vinegar, and smoked paprika in a small bowl. Adjust sweetness or tanginess to taste. (5 minutes)
  7. Glaze the meat: Remove corned beef from slow cooker and place on a foil-lined baking sheet. Brush mustard glaze all over the top. Optionally broil for 3-5 minutes for a caramelized finish. (10 minutes)
  8. Slice and serve: Let meat rest for 5 minutes before slicing against the grain into thin slices. Serve with cabbage, carrots, and potatoes, spooning some cooking liquid on the side. (5 minutes)

Notes

Rinse the brisket to reduce saltiness. Add cabbage in the last hour to avoid mushiness. Broiling the glazed meat is optional but adds a nice texture. Use a slow cooker liner or spray to ease cleanup. Adjust glaze sweetness and tanginess to taste. Substitute potatoes with parsnips or rutabaga for variation. For a low-carb option, replace potatoes with turnips or cauliflower. Vegetarian version possible with smoked tofu or seitan and vegetable broth.
