Ingredients
- 3 lbs lamb shoulder
- 3 tbsp za'atar seasoning
- 2 tsp lemon zest
- 3 tbsp lemon juice
- 1/4 cup olive oil
- 4 cloves garlic cloves, minced
- 1 tsp salt
- 1 tsp black pepper
- 3 sprigs fresh rosemary sprigs
Instructions
- Step 1: Preheat oven to 300°F (150°C). In a small bowl, whisk together 1/4 cup olive oil, 3 tbsp za'atar seasoning, 2 tsp lemon zest, 3 tbsp lemon juice, 4 minced garlic cloves, 1 tsp salt, and 1 tsp black pepper until well combined.
- Step 2: Pat dry 3 lbs lamb shoulder and rub the za'atar marinade all over the meat, ensuring even coating. Place lamb in a roasting pan and tuck 3 fresh rosemary sprigs around it.
- Step 3: Cover roasting pan tightly with foil and roast in preheated oven for 3.5 to 4 hours, until the lamb is fork-tender and the meat easily pulls apart.
- Step 4: Remove foil and increase oven temperature to 425°F (220°C). Roast uncovered for an additional 15 minutes to develop a golden crust. Let rest for 15 minutes before slicing and serving.
