Equipment

  • Large slow cooker (6–8 quart)
  • Cutting board and knife
  • Measuring Cups and Spoons
  • Tongs or slotted spoon
  • Serving platter

Ingredients
  

  • 3–4 lb corned beef brisket (with seasoning packet)
  • 1 small head of cabbage, cut into wedges
  • 4–5 carrots, peeled and chopped
  • 6–8 small potatoes (Yukon Gold or red), halved
  • 1 large onion, quartered
  • 2–3 garlic cloves, smashed
  • 2 bay leaves
  • 1 tsp whole peppercorns
  • Optional: 2 cups low-sodium beef broth or Guinness beer
  • Optional: 1 tsp mustard seeds

Instructions
 

  • Layer vegetables: Place potatoes, carrots, and onions at the bottom of the slow cooker.
  • Add brisket: Rinse corned beef under cold water to remove excess salt. Pat dry and place fat side up on top of vegetables.
  • Season: Sprinkle seasoning packet over meat. Add garlic, bay leaves, peppercorns, and mustard seeds if using. Pour in broth or beer.
  • Cook:
    On low for 8–10 hours
    On high for 4–6 hours
  • Add cabbage: During the last 2 hours, tuck cabbage wedges around the meat.
  • Slice and serve: Remove brisket and let rest 10 minutes. Slice against the grain. Serve with vegetables and broth.

Notes

  • Flat-cut brisket slices more evenly and stays juicy.
  • Don’t skip the seasoning packet — it’s key to flavor.
  • Add cabbage late to avoid mushiness.
  • Slice against the grain for tender meat.
  • Make-ahead: Cook brisket a day ahead and reheat gently.
  • Storage: Refrigerate leftovers up to 4 days. Freeze brisket (without cabbage) for 2 months.
