Step One: Remove corned beef brisket and seasoning packet from the package. Blot excessive slime from corn beef.

Step Two: In a large Dutch oven, place the corned beef with fat side up, in the Dutch oven. Pour the beer and water around the corned beef. Note: The liquid should just come to the bottom of the top fat layer. Sprinkle seasoning packet on top, fresh crushed black pepper, smashed garlic cloves, and rosemary. Over medium-high heat, bring the corned beef brisket in the Dutch oven to a boil, then reduce to medium-low and cover with a tight lid.
12 oz beer, 2 cup water, 4 cloves garlic, 2-3 sprigs fresh rosemary
Step Three: Allow the corned beef to simmer gently for 1.5 - 2 hours, or until it is fork-tender. Check periodically to ensure the liquid is simmering gently; adjust the heat as needed. Chop the vegetables
Step Four: Heat the oven to 350. Place the corned beef on a plate. Discard 1/2 the cooking liquid in the Dutch oven. Make a platform out of the chopped carrots and onions on the bottom of the Dutch oven. Place the corned beef on top of the carrot-onion platform. Nestle the cabbage wedges and potatoes around the corned beef. Sprinkle with salt and pepper on top of vegetables and corned beef roast.
1 large onion, 3 large carrots, 5 potatoes, small to medium, 1 head green cabbage
Step Five: Put the lid back on the Dutch oven and place in the oven. Bake for at least an hour or until the vegetables are fork tender. Note: Cooking time will vary according to the size of the corned beef.
Step Six: Once done, remove the corned beef brisket from the Dutch oven and transfer it to a cutting board. Allow it to rest for a few minutes before slicing. Slicing against the grain, cut into slices to your desired thickness.
