Instructions

  1. Step 1: In a large bowl, combine 2 lbs lamb shoulder cubes with 2 tbsp chopped fresh rosemary, 5 minced garlic cloves, 3 tbsp olive oil, 1 tbsp lemon juice, 1 1/2 tsp salt, and 1 tsp black pepper. Toss well to coat and marinate for at least 1 hour in the refrigerator.
  2. Step 2: Preheat oven to 300°F (150°C). Spread the marinated lamb evenly on a roasting pan and roast uncovered for 2 hours, turning once halfway through, until the lamb is tender and edges are caramelized.
  3. Step 3: While the lamb roasts, prepare the herb sauce by mixing 1/4 cup chopped parsley, 1/4 cup chopped cilantro, 1 finely chopped small green chili, and 2 tbsp water in a small bowl.
  4. Step 4: Remove lamb from oven and drizzle the fresh herb sauce over the warm meat before serving, enhancing the tender lamb’s flavor with bright herbal notes.
