Ingredients
- 4 lbs lamb shoulder bone-in
- 4 sprigs fresh rosemary sprigs
- 1/4 cup chopped fresh mint leaves
- 6 cloves minced garlic cloves
- 3 tbsp olive oil
- 2 tsp sea salt
- 1 tsp freshly ground black pepper
- 1 tsp lemon zest
- 1 cup beef broth
Instructions
- Step 1: Preheat oven to 300°F. In a small bowl, combine 3 tbsp olive oil, 6 minced garlic cloves, 1/4 cup chopped fresh mint leaves, 4 sprigs chopped fresh rosemary, 2 tsp sea salt, 1 tsp freshly ground black pepper, and 1 tsp lemon zest. Rub this mixture evenly all over the 4 lbs bone-in lamb shoulder.
- Step 2: Place the lamb shoulder fat side up in a roasting pan and pour 1 cup beef broth into the pan to keep the meat moist. Cover loosely with foil and roast in the oven for 3.5 to 4 hours, basting every hour with pan juices, until the meat is tender and pulls easily from the bone.
- Step 3: Remove the foil for the last 30 minutes of cooking to allow the lamb to develop a golden brown crust. Let rest for 15 minutes before slicing and serving with the pan juices spooned over.
