Instructions

  1. Step 1: Preheat oven to 400°F. Pat dry 8 lamb chops, then rub each with 2 tbsp za’atar, 3 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper, coating evenly.
  2. Step 2: Arrange the lamb chops on a baking sheet and roast for 15-18 minutes, flipping halfway, until cooked to medium doneness and juices run clear.
  3. Step 3: While lamb cooks, toss 1 thinly sliced red onion with 1 tbsp sumac powder and 2 tbsp lemon juice in a bowl; let marinate for 10 minutes until the onions soften and become tangy.
  4. Step 4: Remove lamb chops from oven and rest for 5 minutes. Plate and top with the sumac onions and sprinkle 2 tbsp chopped fresh parsley before serving.
