01 - Rinse the corned beef brisket under cold water and pat dry. Place it, fat side up, in the bottom of a large slow cooker.
02 - Sprinkle the included spice packet or pickling spice, bay leaves, peppercorns, and garlic over the brisket.
03 - Scatter the onions, carrots, and potatoes around the brisket.
04 - Pour in the beef broth and water, ensuring the brisket is nearly covered with liquid.
05 - Cover and cook on LOW for 7 hours.
06 - After 7 hours, carefully add the cabbage wedges on top of the other vegetables. Re-cover and cook for 1 more hour, or until the cabbage is tender and the brisket is fork-tender.
07 - Transfer the brisket to a cutting board, tent with foil, and let rest for 10 minutes. Slice against the grain.
08 - Arrange the sliced brisket and vegetables on a platter. Spoon some cooking liquid over the top before serving.
