Equipment

  • 1 oven
  • 1 rimmed roasting pan
  • 1 aluminum foil
  • 1 pot

Ingredients
  

  • 2-4 lb corned beef brisket
  • 3-4 tablespoons Grey Poupon Dijon mustard
  • 3-4 tablespoons brown sugar

Instructions
 

  • Remove the corned beef brisket from the package and discard the spice packet.
  • Place the brisket in a pot of water and bring to a boil, then immediately remove it to reduce excess salt.
  • Preheat the oven to 350°F.
  • Place the brisket fat side up on a large piece of aluminum foil.
  • Rub the top and sides of the brisket evenly with Dijon mustard.
  • Sprinkle brown sugar over the mustard-coated brisket and gently pat it on.
  • Wrap the brisket loosely with the foil, leaving some space inside, and place it in a rimmed roasting pan.
  • Bake the covered brisket for 2 hours, adjusting time for larger cuts (about 45-60 minutes per pound).
  • Uncover the brisket, turn on the oven broiler (low setting if available), and caramelize the top for a few minutes, watching carefully to prevent burning.
  • Remove the brisket from the oven and let it rest for 10-15 minutes before slicing against the grain.

Notes

  • Boiling before baking removes excess salt from the corned beef.
  • Add baby potatoes or cabbage around the brisket for a complete meal; adjust cooking times accordingly.
  • Store leftovers in an airtight container in the fridge for 3-4 days.
  • Reheat slices wrapped in foil in a 350°F oven to retain juiciness.
