Heavy-duty aluminum foil
Sharp carving knife
Meat thermometer
- 3 –4 lbs corned beef brisket with spice packet
- 1 medium green cabbage cut into wedges
- 3 –4 large carrots peeled and cut
- 4 –6 small red or Yukon gold potatoes quartered
- 2 –3 cups beef broth or vegetable broth or water
- 3 –4 garlic cloves smashed
- 1 tbsp Dijon or yellow mustard optional, for glaze
- 1 tbsp brown sugar optional, for glaze
- Freshly cracked black pepper to taste
- Optional: parsnips Brussels sprouts, onions, bay leaf
Preheat oven to 325°F (165°C). Rinse the corned beef under cold water and place fat-side up on a rack in a roasting pan.
Sprinkle the seasoning packet over the brisket. For a glaze, mix mustard and brown sugar and rub it over the top.
Pour broth into the bottom of the pan, about ½ inch deep. Cover tightly with foil.
Roast for 2.5 to 3.5 hours (about 50 minutes per pound), until the internal temperature reaches 195–205°F.
In the final hour of roasting, remove from oven, add cabbage, carrots, and potatoes around the brisket, and re-cover with foil.
Roast for the remaining time until veggies are tender. Remove from oven, tent loosely with foil, and rest for 15–20 minutes.
Slice brisket against the grain and serve with veggies. Optional: brush glaze on and broil uncovered for the last 20 minutes for a crust.
Pro Tips
- Let the meat rest before slicing to lock in juices.
- Leave the fat cap on while roasting for flavor and moisture.
- For a low-carb version, skip the potatoes and use cauliflower or Brussels sprouts.
- Substitute beef broth with black tea or apple juice for depth.
