Ingredients

  • ¼ cup honey

  • 3 cloves garlic, minced

  • 2 tablespoons chopped fresh rosemary

  • 2 tablespoons prepared Dijon-style mustard

  • 1 teaspoon lemon zest

  • 1 teaspoon freshly ground black pepper

  • 5 pounds whole leg of lamb

  • 1 teaspoon coarse sea salt

Directions

  1. Mix honey, garlic, rosemary, mustard, lemon zest, and pepper together in a small bowl. Place lamb in a flat dish; rub mixture over lamb. Cover with plastic wrap and marinate in the refrigerator 8 hours to overnight.

  2. Preheat the oven to 450 degrees F (230 degrees C). Transfer lamb onto a rack in a roasting pan and sprinkle with salt to taste.

  3. Bake in the preheated oven for 20 minutes, then reduce heat to 400 degrees F (200 degrees C) and roast for 55 to 60 more minutes for medium rare. An instant-read thermometer inserted into the center should read at least 120 degrees F (50 degrees C). Let lamb rest for about 10 minutes before carving.

Editor's Note:

USDA recommends cooking all raw lamb steaks, chops, and roasts to a minimum internal temperature of 145 degrees F (63 degrees C) as measured with a food thermometer before removing meat from the heat source.
