Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 pounds baby potatoes, halved or quartered if large
  • 1 large yellow onion, cut into thick wedges
  • 3-4 large carrots, peeled and cut into 2-inch chunks
  • 1 small head of green cabbage, cut into 8 wedges core intact
  • 3 tablespoons olive oil, divided
  • 2 tablespoons whole grain mustard
  • 2 tablespoons brown sugar
  • 1 tablespoon apple cider vinegar
  • Kosher salt and black pepper, to taste
  • Fresh parsley, chopped for garnish

Equipment

  • Rimmed baking sheet (half sheet pan)
  • Wire rack (for the baking sheet)
  • Cutting board
  • Chef's knife
  • Mixing bowls (small and large)
  • Paper towels
  • Pastry brush (or spoon for glaze)
  • Measuring spoons and cups
  • Meat thermometer

Method
 

  1. Preheat oven to 400°F (200°C). Place a wire rack inside a rimmed baking sheet.
  2. Pat the corned beef brisket completely dry with paper towels. Place it fat-side up on the wire rack. Discard or save the spice packet.
  3. In a small bowl, mix the whole grain mustard, brown sugar, and apple cider vinegar to form a glaze. Brush it generously over the top and sides of the brisket.
  4. Roast the brisket alone on the center rack for 30 minutes.
  5. While the beef cooks, prepare vegetables. On a separate baking sheet or in a large bowl, toss the potatoes, onion wedges, and carrot chunks with 2 tablespoons of olive oil. Season lightly with salt and pepper.
  6. After the beef's initial 30 minutes, carefully remove the pan from the oven. Arrange the oiled potatoes, onions, and carrots around the brisket on the sheet pan, tucking them onto the pan around the wire rack.
  7. Add the cabbage wedges to the pan, nestling them in. Drizzle the cabbage lightly with the remaining 1 tablespoon of olive oil.
  8. Return the loaded sheet pan to the oven. Roast for another 25-35 minutes, or until the vegetables are tender and the internal temperature of the corned beef reaches at least 145°F (63°C).
  9. Transfer the corned beef to a cutting board and let it rest for 10 minutes. Optionally, return the vegetables to the oven to crisp further while the meat rests.
  10. Slice the corned beef thinly against the grain. Arrange on a platter with the roasted vegetables. Garnish with chopped parsley and serve.

Notes

For best browning, ensure the corned beef is patted very dry before applying the glaze. Do not overcrowd the pan; use two sheet pans if necessary to prevent steaming. The corned beef is already salty, so season vegetables lightly. For more fall-apart tender meat, cook to an internal temperature of 160°F (71°C). Leftovers make excellent hash. Variations: Add a tablespoon of orange marmalade to the glaze, scatter kielbasa sausage with the vegetables, or pop sliced beef under the broiler for 2-3 minutes for extra crispness.
