Ingredients
- 3 lbs lamb shoulder
- 4 sprigs fresh rosemary sprigs
- 6 cloves garlic cloves
- 3 tbsp olive oil
- 2 tsp sea salt
- 1 tsp black pepper
- 1 cup water
Instructions
- Step 1: Preheat your oven to 300°F (150°C). Finely chop 4 sprigs of fresh rosemary and mince 6 garlic cloves. Mix them with 3 tablespoons olive oil, 2 teaspoons sea salt, and 1 teaspoon black pepper to create a herb paste.
- Step 2: Rub the herb paste all over the 3-pound lamb shoulder, ensuring it is evenly coated. Place the lamb in a roasting pan and pour 1 cup of water into the base to keep the meat moist.
- Step 3: Cover the roasting pan with foil and roast the lamb in the preheated oven for 3 hours, checking occasionally to baste with pan juices. Remove the foil for the last 30 minutes to allow the crust to brown and become fragrant.
