Stove-Top (Dutch Oven) Instructions:
Prep the beef
Rinse the corned beef brisket under cold water to remove excess salt. Place it fat-side up in a large Dutch oven.
Add seasoning and liquid
Sprinkle in the spice packet, bay leaves, peppercorns, and onion. Pour in enough beef broth (or water) to just cover the meat.
Simmer the brisket
Bring to a boil, then reduce to low heat. Cover and simmer for 2.5 to 3 hours, or until the meat is fork tender.
Add the potatoes and carrots
Once the beef is nearly done, add the potatoes and carrots to the pot. Cover and cook for another 20 minutes, or until vegetables are just tender.
Add the cabbage
Add the cabbage wedges on top and continue to cook 15 more minutes, or until soft but not falling apart.
Rest and slice
Remove the brisket and let it rest for 10 minutes before slicing across the grain. Serve with the vegetables and some ladled cooking broth.
Slow Cooker Instructions:
Follow the same ingredient prep.
Place the brisket, onion, spices, and broth in the crockpot.
Cook on LOW for 8–9 hours or HIGH for 4–5 hours.
Add potatoes and carrots during the last 2 hours, and add the cabbage during the last hour.
