01 - Rinse the corned beef brisket under cold water to remove excess brine. Place it in a large Dutch oven or heavy-bottomed pot.
02 - Add the seasoning packet, garlic, bay leaves, black peppercorns, mustard seeds, and coriander seeds. Pour in beef broth and water to cover the meat.
03 - Bring to a boil over medium-high heat. Reduce heat to low, cover, and simmer for 2 hours.
04 - Add potatoes, carrots, and onion to the pot. Cover and cook for 30 minutes.
05 - Place cabbage wedges on top of the meat and vegetables. Cover and cook for another 30 minutes, or until vegetables are tender and meat is fork-tender.
06 - Remove the corned beef from the pot and let it rest for 10 minutes. Slice across the grain.
07 - Serve sliced corned beef with vegetables and a ladle of cooking broth.
