Ingredients

Scale
  • 34 lbs corned beef brisket (with seasoning packet)
  • 4 cups water
  • 3 medium carrots, peeled and cut into chunks
  • 4 medium potatoes, halved or quartered (Yukon Gold recommended)
  • 1 large onion, quartered
  • 3 cloves garlic, smashed
  • 1/3 cup brown sugar (70 g)
  • 1/4 cup Dijon mustard (60 ml)
  • 2 tablespoons whole grain mustard (30 ml)
  • 1 tablespoon apple cider vinegar (15 ml)
  • 1 teaspoon black peppercorns
  • 2 bay leaves

Instructions

  1. Add 4 cups of water to the slow cooker pot. Toss in quartered onion, carrot chunks, garlic cloves, black peppercorns, and bay leaves to create a flavorful broth. (5 minutes)
  2. Rinse the corned beef brisket under cold water to remove excess brine and pat dry with paper towels. (5 minutes)
  3. Place the corned beef fat side up into the broth and vegetables in the slow cooker. (1 minute)
  4. Cover and cook on low for 6-8 hours until the meat is tender and fork-ready. Avoid opening the lid frequently. (6-8 hours)
  5. In a small bowl, whisk together brown sugar, Dijon mustard, whole grain mustard, and apple cider vinegar until smooth to make the glaze. (5 minutes)
  6. About 1.5 hours before the end of cooking, add halved potatoes around the meat in the slow cooker. (1.5 hours)
  7. When the corned beef is tender, brush the glaze generously over the top. Turn the slow cooker to high and cook uncovered for 15-20 minutes to caramelize the glaze. (20-25 minutes)
  8. Remove the corned beef from the slow cooker and let it rest for 10 minutes before slicing against the grain. Serve with cooked vegetables and extra glaze. (10 minutes)

Notes

Rinse the corned beef to reduce saltiness. Apply glaze near the end to avoid burning. Rotate meat halfway through cooking if your slow cooker cooks unevenly. Save extra glaze for leftovers and loosen with water if thickened.
