Equipment

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

Ingredients
  

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

Instructions
 

  • Remove the brisket from the package and discard the included spice pack.
  • Place the brisket in a pot of water and bring to a boil, then immediately remove to reduce excess salt.
  • Preheat the oven to 350°F.
  • Place the brisket fat side up in the center of a large piece of aluminum foil.
  • Rub the brisket evenly with Dijon mustard and sprinkle brown sugar over the top and sides, patting gently to adhere.
  • Loosely cover the brisket with the foil, leaving some space between the meat and foil, then set it in a rimmed roasting pan.
  • Bake the brisket for 2 hours, adjusting time if the brisket is larger, approximately 45-60 minutes per pound.
  • After baking, open the foil and broil on low or place on a lower oven rack to caramelize the topping, watching closely to prevent burning.
  • Remove the brisket from the oven and let rest for 10-15 minutes before slicing against the grain.

Notes

  • Boil briefly first to reduce saltiness from curing brine.
  • Add potatoes or cabbage towards the end for a full meal.
  • Store leftovers in an airtight container in the refrigerator for 3-4 days.
  • Reheat wrapped in foil in the oven at 350°F to keep meat juicy.
