Key Ingredients

• 3 pounds corned beef brisket with spice packet
• 1/4 cup Dijon mustard
• 1/4 cup light brown sugar
• 1 tablespoon Worcestershire sauce
• 1/2 cup water
• 1 pound carrots, peeled and cut into 2-inch chunks
• 1 pound red potatoes, halved
• 1 head green cabbage, cut into 8 wedges

Step-by-Step Instructions

1. Preheat your oven to 350°F and prepare a large rimmed sheet pan.
2. Rinse the corned beef under cold water to remove excess brine, pat it dry with paper towels, and score the fat cap in a diagonal pattern.
3. Place the brisket inside a 15×17-inch oven roasting bag and whisk together the Dijon mustard, brown sugar, and Worcestershire sauce to brush over the meat.
4. Add 1/2 cup of water to the bag, secure the top with a tie, snip a few steam vents in the top, and bake on the sheet pan for 3 hours.
5. While the beef roasts, toss the carrots and potatoes in a bowl with olive oil, salt, and pepper to coat evenly.
6. After 3 hours, remove the beef from the oven, transfer it to a cutting board to rest under foil, and discard the roasting bag and juices.
7. Increase the oven temperature to 425°F, spread the prepared vegetables and cabbage wedges onto the sheet pan in a single layer, and roast for 20-25 minutes until tender.
8. Slice the rested corned beef against the grain into thin strips and serve on a platter surrounded by the roasted vegetables and mustard glaze.

This Corned Beef with Mustard Glaze is a stunning centerpiece that elevates the classic holiday brisket into something truly special. The combination of a slow, steady cook and a final pass under the broiler results in meat that is incredibly tender on the inside with a beautifully caramelized, zesty crust on the outside.

Whether you choose to prepare this in the oven, a slow cooker, or a pressure cooker, the secret to success lies in the low and slow approach and that final glazing step. Don’t forget to let the meat rest before slicing against the grain to ensure every bite is succulent and juicy.
