Season the Chicken
Preheat your oven to 180°C / 350°F.In a large bowl, mix olive oil, sumac, lemon juice, salt, black pepper, allspice, and cinnamon. Coat the chicken thoroughly, ensuring the seasoning reaches all sides. Roast the Chicken
Arrange the chicken pieces skin-side up on a baking tray. Roast uncovered for 50–60 minutes, turning once halfway, until the chicken is fully cooked and golden brown. Reserve the pan juices for assembly. Caramelize the Onions
While the chicken roasts, heat olive oil in a wide pan over medium heat. Add sliced red onions and cook slowly for 15–20 minutes, stirring frequently, until soft, glossy, and lightly caramelized.Season with salt, black pepper, and sumac. Remove from heat. Toast the Nuts
In a small dry pan, toast pine nuts or almonds over low heat until lightly golden. Set aside. Assemble the Musakhan
Place flatbread on a large serving platter. Spread a thick, even layer of the caramelized onions over the bread, allowing the olive oil to soak in. Add the Chicken
Arrange the roasted chicken pieces on top of the onion-covered bread. Spoon some of the reserved pan juices over the chicken for extra flavor and moisture. Garnish
Sprinkle toasted nuts generously over the dish for texture and visual appeal. Serve Warm
Serve immediately while warm. Musakhan is traditionally eaten by hand and shared family-style.
