Corned beef rewards the same low-and-slow patience as a good pot roast — the crockpot breaks down the tough brisket into something that shreds apart with a fork.
Adding the cabbage only for the last hour is the one timing detail that keeps it from turning into mush by serving time.
Hold the cabbage back until the final hour of cooking — added at the start alongside the tougher vegetables, it turns completely mushy well before the meat is done.
Save this recipe for later — pin it to your crockpot board.
Place carrots, potatoes and onion in the bottom of the crockpot. Set the corned beef brisket on top, fat-side up, and sprinkle with the included spice packet.
Pour in beef broth or water until it comes about halfway up the sides of the meat. Add bay leaves.
Cover and cook on low for 7 hours.
Nestle the cabbage wedges into the liquid around the meat. Cover and cook 1 more hour until the beef is fork-tender and cabbage is soft.
Remove the beef and let rest 10 minutes, then slice against the grain. Serve with the vegetables and cabbage.
Cabbage cooks much faster than the tougher root vegetables and the brisket — adding it for just the last hour keeps it tender instead of turning to mush over the full 8-hour cook.
Corned beef brisket has long muscle fibers — slicing across them shortens the fibers and makes each bite noticeably more tender than slicing with the grain.
Yes — the packets are portioned for the brisket they come with regardless of size; it's meant to season the cooking liquid, not coat the meat directly.
