Ingredients

Scale
  • 3 to 4 pounds corned beef brisket with spice packet
  • 1/4 cup yellow mustard
  • 2 tablespoons brown sugar
  • 1 tablespoon apple cider vinegar
  • 3 large garlic cloves, minced or smashed
  • 4 medium carrots, peeled and cut into chunks
  • 1 pound baby potatoes, halved or whole if small (Yukon Gold or red potatoes)
  • 2 medium parsnips, peeled and sliced into thick pieces (optional)
  • 1 large onion, quartered (yellow or white)
  • 2 bay leaves
  • 1 teaspoon whole black peppercorns
  • 4 cups water

Instructions

  1. Prep your vegetables: peel and chunk the carrots, parsnips, and potatoes. Quarter the onion. Set aside.
  2. Rinse the corned beef brisket under cold water to reduce excess saltiness. Pat dry with paper towels.
  3. Place the corned beef fat side up in the slow cooker insert.
  4. Scatter the carrots, potatoes, parsnips, and onion around and on top of the brisket. Add bay leaves, peppercorns, and minced garlic.
  5. Pour enough water to cover about half of the brisket (around 4 cups) into the slow cooker.
  6. Cover and cook on LOW for 8 to 10 hours until the meat is fork-tender and vegetables are soft but not mushy. Skim off any foam or scum that appears.
  7. About 30 minutes before serving, whisk together yellow mustard, brown sugar, and apple cider vinegar in a small bowl to make the mustard glaze.
  8. Carefully remove the brisket from the slow cooker and place it on a baking sheet or ovenproof dish. Spread the mustard glaze evenly over the top.
  9. Place under a preheated broiler for 10–15 minutes until bubbly and caramelized, watching closely to avoid burning.
  10. Slice the corned beef against the grain and serve alongside the cooked vegetables. Spoon some cooking liquid over the meat for extra juiciness.

Notes

Rinse the brisket to reduce saltiness. Cook low and slow for tender meat. Skim foam during cooking. Broil the glaze carefully to avoid burning. Let meat rest after broiling to redistribute juices. Leftovers store well in the fridge for up to 4 days. For gluten-free, verify mustard and spice packet ingredients.
