Instructions

Step 1: In a large bowl, combine 3 tbsp olive oil, 2 tbsp za'atar, 4 minced garlic cloves, 2 tbsp lemon juice, 1 tsp salt, and 1/2 tsp black pepper. Add 6 bone-in chicken thighs and coat thoroughly. Marinate for at least 30 minutes.
Step 2: Preheat the oven to 400°F (200°C). Arrange the marinated chicken thighs on a baking sheet lined with parchment paper, skin side up.
Step 3: Bake the chicken for 35-40 minutes until the skin is golden and juices run clear when pierced.
Step 4: While the chicken bakes, toss 1 large thinly sliced red onion with 1 tbsp sumac powder and a pinch of salt. Let it sit for 10 minutes to soften and absorb the tangy flavor.
Step 5: Remove the chicken from the oven and top with the sumac onions and 2 tbsp chopped fresh parsley before serving.
