  • 4 lb corned beef
  • 1/4 cup honey mustard
  • 1/4 cup whole grain mustard
  • 1 Tbsp brown sugar light
  • Cabbage and Potatoes


  • Preheat oven to 325°F.
  • Remove the meat and spice packet from the package.
  • Lay the meat, fat side up, on a large piece of heavy-duty aluminum foil (large enough to fold seals on top and 2 ends).
  • Evenly sprinkle peppercorns from package over the beef.
  • In a small bowl, whisk together honey mustard, whole grain mustard, and brown sugar until combined.
  • Spread half of the mustard mixture over the top of the meat.
  • Reserve remaining mustard to serve on the side
  • Wrap the corned beef with foil so that space is left on top in between the corned beef and the foil
  • Place foil-wrapped corned beef in a shallow roasting pan and bake for 2 hours.
  • Open the foil wrapping and bake another 30 minutes, until the top is lightly browned.
  • Let the meat rest for 10 to 15 minutes, then place on cutting board and cut at a diagonal, across the grain of the meat, into 1/2-inch thick slices.
  • Serve with reserved mustard on the side.
