This leg of lamb is marinated overnight with fresh rosemary, garlic, mustard, honey, and lemon zest. Be prepared for many requests for seconds!
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
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.
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.
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.
