Ingredients
  

Protein

  • 4 to 5.5 pounds corned beef brisket, rinsed in cool water

Aromatics & Seasoning

  • 1 large yellow onion, halved and cut into 1/4-inch slices
  • 4 large garlic cloves, peeled and lightly smashed
  • 1 large dried bay leaf
  • 2 tablespoons pickling spice

Liquid

  • 8 ounces beer
  • 2-4 cups water (add as needed during cooking)

Vegetables

  • 1.5 to 2 pounds baby potatoes
  • 1 pound baby carrots
  • 1 medium green cabbage, cut into 6–8 wedges

Finishing & Serving

  • melted butter, chopped parsley, salt, and pepper (for garnishing, optional)
  • whole grain mustard or horseradish sauce (for serving, optional)

Instructions
 

Preparation

  • Place the rinsed brisket fat-side up in the slow cooker.
  • Scatter the onion, garlic, bay leaf, and pickling spice around it.
  • Pour the beer and 1 cup of water into the cooker—liquid should come about halfway up the brisket.
  • Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until fork-tender.
  • If the liquid level looks low partway through cooking, add up to 1–2 cups more water.

Cooking

  • About 2–3 hours before serving on LOW (or 1 hour on HIGH), add the baby potatoes and carrots around the brisket. Replace the lid.
  • Add the cabbage with about 30–45 minutes left, cooking until tender but still holding shape.
  • Transfer the brisket to a cutting board, tent with foil for 10 minutes, then slice against the grain into 1/4-inch slices.
  • Serve with the cooked potatoes, carrots, and cabbage. Spoon some cooking liquid over for extra flavor.

Notes

Rinse the brisket well to remove excess brine for balanced saltiness. For a lightly spicy flavor, stir some horseradish into the cooking liquid before serving. Leftovers are great for sandwiches.
