Tips & Variations
- If you don’t have a roasting pan with a rack, place the brisket on a bed of chopped onions or an oven-safe rack inside a rimmed baking sheet.
- Use a meat thermometer to check doneness; the internal temperature should reach between 180°F and 195°F for tender meat.
- For extra flavor, brush on additional mustard halfway through baking or add sliced garlic to the water in the pan.

FAQs
Can I cook the corned beef without the spice packet?
Yes, but the spice packet adds essential flavors. You can substitute with a mixture of mustard seeds, coriander, peppercorns, and bay leaves.
Should I boil the corned beef before baking?
Boiling isn’t necessary for this recipe. Baking the brisket covered with water allows it to cook slowly and stay moist while developing a flavorful crust.

Description
This Baked Corned Beef recipe offers a tender, flavorful brisket cooked low and slow in the oven with a tangy Dijon mustard crust and traditional spices. Perfect for a comforting meal, the method ensures juicy meat that slices beautifully and pairs well with your favorite side dishes.
Ingredients
Main Ingredients
- 1 corned beef brisket with spice packet (about 4 pounds)
- 1/4 cup Dijon mustard
Instructions
- Season the Corned Beef Brisket: Begin by spreading the Dijon mustard evenly over the fat side of the corned beef brisket. Then, sprinkle the contents of the provided spice packet over the top, ensuring the spices adhere well to the mustard-coated meat.
- Preheat the Oven and Prepare the Roasting Pan: Set your oven to 350°F (175°C). Place the seasoned corned beef, fat side up, on a rack inside a roasting pan. If you don’t have a roasting pan with a rack, use an oven-safe rack placed inside a rimmed baking sheet or set the meat on a bed of chopped onions to keep it elevated.
- Add Water and Cover Tightly: Pour 1/2 inch of water into the bottom of the pan to create steam during baking. Then cover the pan tightly with aluminum foil to trap moisture and ensure even cooking.
- Bake Until Tender: Place the covered pan in the preheated oven and bake for 2 to 3 hours, or until the corned beef is fork-tender. Check periodically, adding more water as needed to maintain moisture. For best results, use a meat thermometer and cook until the internal temperature reaches between 180°F and 195°F (82°C to 90°C).
- Rest the Meat: After baking, remove the corned beef from the oven and let it rest, still covered, for 10 minutes to allow juices to redistribute.
- Slice and Serve: Uncover the meat and cut diagonally against the grain into thin slices. Serve immediately with your preferred sides.
Notes
- If you don’t have a roasting pan with a rack, an oven-safe wire rack or a bed of chopped onions can be used to elevate the meat.
- Adding water to the pan during cooking helps keep the meat moist by creating steam.
- Letting the meat rest before slicing helps retain its juices for a more tender bite.
- Use a meat thermometer to ensure the meat is cooked to the ideal internal temperature of 180°–195°F.
