Ingredients

Instructions

  1. Step 1: In a bowl, combine 1/4 cup extra virgin olive oil, 2 tbsp chopped fresh rosemary, 2 tbsp chopped fresh oregano, 5 minced garlic cloves, 3 tbsp lemon juice, 1 tsp dried thyme, 2 tsp sea salt, and 1 tsp freshly ground black pepper to create a fragrant marinade.
  2. Step 2: Rub the marinade all over the 4 lbs bone-in lamb shoulder, making sure to coat it evenly. Cover and marinate in the refrigerator for at least 4 hours or overnight for best flavor.
  3. Step 3: Preheat your oven to 325°F (160°C). Place the marinated lamb shoulder in a roasting pan and pour in 1/2 cup water to keep the meat moist.
  4. Step 4: Roast the lamb uncovered for 3 to 3.5 hours, basting every 45 minutes with pan juices, until the meat is tender and pulls easily away from the bone.
  5. Step 5: Remove from oven and let rest for 15 minutes before slicing. Serve warm, spooning pan juices over the lamb for extra moisture and flavor.
