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 top of the corned beef.
03 - Arrange the quartered potatoes, carrots, onion wedges, and smashed garlic cloves around and on top of the beef.
04 - Pour in the beef broth and water, ensuring the beef is just barely covered. Tuck in the bay leaves and add 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 - Arrange the cabbage wedges on top of the cooking mixture during the last 2 hours of cooking time.
07 - Transfer the brisket to a cutting board and let rest for 10 minutes before slicing against the grain into thin slices.
08 - Serve the sliced beef accompanied by the tender vegetables. Ladle some of the cooking liquid over each portion for added moisture and flavor.
