Ingredients

Instructions

  1. Step 1: Preheat oven to 300°F. In a small bowl, mix 3 tbsp finely chopped fresh rosemary, 6 minced garlic cloves, 4 tbsp olive oil, 2 tsp sea salt, 1 tsp black pepper, 1 tsp dried thyme, and 1 tbsp lemon zest to create an herb paste.
  2. Step 2: Pat dry 4 lbs bone-in lamb shoulder and rub the herb mixture all over the lamb, pressing to adhere evenly.
  3. Step 3: Place lamb in a roasting pan with 3 large chopped carrots and 1 large quartered yellow onion surrounding it. Pour 1 cup red wine into the bottom of the pan.
  4. Step 4: Cover loosely with foil and roast for 4 hours, basting every hour with pan juices, until lamb is fork-tender and pulls apart easily.
  5. Step 5: Remove foil and increase oven temperature to 425°F. Roast uncovered for an additional 15 minutes to brown and crisp the herb crust.
  6. Step 6: Let rest for 15 minutes before slicing and serving with the roasted vegetables and pan sauce.
