Place the roast fat side down in the center of the Dutch oven or pot. If using potatoes and carrots, place them on the sides of the roast.
Sprinkle the seasoning packet over the beef, then pour in 1 inch of water or broth. Cover the pot with the lid.Add wedges of cabbage (optional) during the last 5 minutes of cooking so they do not get soggy.
Roast for 50 minutes per pound (about 3 hours for a 3.5-pound corned beef brisket roast) in the preheated oven until the meat is so tender that it can be flaked apart with a fork. Check the internal temperature of the meat to ensure it's 155℉.
Let meat rest for 30 minutes, then slice against the grain before serving.

Notes
Let the meat rest before slicing – Allowing it to rest for 10-15 minutes keeps the juices locked in for maximum flavor.
Recipe Variations:
Guinness braised: Replace some of the cooking liquid with Guinness beer for a deep, malty flavor.
Spicy: Add red pepper flakes or extra black pepper for a little heat.
Sweet and savory glaze: Brush the cooked meat with a brown sugar and Dijon mustard glaze before broiling for a caramelized crust.
Garlic and herb: Add fresh garlic, rosemary, and thyme for an herbaceous flavor boost.
