Instructions

  1. Step 1: Preheat your oven to 325°F. Pat dry 3 pounds of spring lamb shoulder and rub it all over with 3 tablespoons olive oil, 1.5 teaspoons kosher salt, 1 teaspoon ground black pepper, 6 minced garlic cloves, 2 tablespoons chopped fresh rosemary, and 1 teaspoon lemon zest until evenly coated.
  2. Step 2: Place the lamb shoulder in a roasting pan fat side up and pour 1 cup of water or lamb stock into the bottom of the pan to keep the meat moist during roasting.
  3. Step 3: Roast uncovered for about 3 hours, basting every 45 minutes with the pan juices, until the lamb is fork-tender and an internal thermometer reads 195°F.
  4. Step 4: Remove from oven and let rest for 15 minutes before carving to allow juices to redistribute, serving warm with the pan juices spooned over.
