01 - Rinse the corned beef brisket under cold water and pat dry with paper towels. Place the brisket fat-side up in the bottom of a large slow cooker.
02 - Sprinkle the included spice packet or pickling spice evenly over the entire surface of the beef.
03 - Arrange the quartered potatoes, carrots, onion wedges, and smashed garlic cloves around and on top of the beef.
04 - Pour the beef broth and water into the slow cooker, ensuring the beef is just barely covered. Add bay leaves and several grinds of black pepper.
05 - Cover and cook on low heat for 8 hours or until the beef and vegetables are fork-tender.
06 - Gently place the cabbage wedges on top of the cooking ingredients during the last 2 hours of cooking time.
07 - Carefully remove the brisket to a cutting board and let rest for 10 minutes before slicing against the grain into thin slices.
08 - Arrange sliced beef and vegetables on serving plates. Ladle some of the cooking liquid over the top for added moisture and flavor.
