Ingredients

Instructions

  1. Step 1: Preheat your oven to 325°F (165°C). In a small bowl, combine 6 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp lemon zest, 3 tbsp olive oil, 2 tsp sea salt, and 1 tsp freshly ground black pepper to make a fragrant herb paste.
  2. Step 2: Pat dry the 4 lbs bone-in lamb shoulder with paper towels. Rub the herb paste all over the lamb, making sure to coat every surface and gently massage the mixture into the meat.
  3. Step 3: Place the lamb shoulder fat-side up in a roasting pan and pour 1 cup of water into the pan to keep the meat moist during roasting.
  4. Step 4: Cover the roasting pan tightly with foil and roast in the preheated oven for 3 hours until the lamb is fork-tender and juices run clear.
  5. Step 5: Remove the foil and increase the oven temperature to 425°F (220°C). Roast the lamb uncovered for an additional 15 minutes to crisp the outer layer and deepen the flavors.
  6. Step 6: Let the lamb rest for 15 minutes before slicing to allow the juices to redistribute, then serve warm with your favorite Mediterranean sides.
