Instructions

  1. Step 1: Heat 3 tbsp olive oil in a large heavy-bottom pot over medium-high heat. Add 1.5 lbs lamb shoulder cubes and brown on all sides, about 6-8 minutes, until nicely caramelized, then remove and set aside.
  2. Step 2: In the same pot, add 1 large finely chopped onion, 4 minced garlic cloves, 2 sliced carrots, and 2 chopped celery stalks. Sauté over medium heat for 6 minutes until softened and fragrant.
  3. Step 3: Stir in 2 tbsp tomato paste, 1 tsp Aleppo pepper, 1/2 tsp ground cinnamon, and 1/2 tsp ground allspice. Cook for 2 minutes until the spices bloom and tomato paste darkens slightly.
  4. Step 4: Return the lamb to the pot and pour in 2 cups beef broth. Season with 1 tsp salt and 1/2 tsp black pepper. Bring to a simmer, reduce heat to low, cover, and cook for 1.5 hours until lamb is tender.
  5. Step 5: Remove the lid and simmer uncovered for an additional 15 minutes to thicken the sauce slightly. Stir in 1 tbsp sumac and 2 tbsp chopped fresh parsley just before serving to add brightness.

Frequently asked questions
