To prepare this delectable Persian Lemon Chicken, follow these simple steps:

1. Prepare the Marinade: In a bowl, combine lemon juice, lemon zest, garlic, cumin, coriander, turmeric, paprika, cayenne pepper, olive oil, salt, and pepper. Whisk until well mixed.
2. Marinate the Chicken: Place the chicken thighs in a large resealable bag or baking dish. Pour the marinade over the chicken, ensuring it’s well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes, or preferably up to an hour.
3. Preheat the Oven: Preheat your oven to 400°F (200°C) while you prepare the next steps.
4. Prepare the Onions: In a skillet, heat a little olive oil over medium heat. Add the sliced onions and sauté until translucent, about 5-7 minutes.
5. Arrange the Chicken: In a large oven-safe baking dish, spread the sautéed onions evenly. Place the marinated chicken thighs on top of the onions, pouring any remaining marinade over them.
6. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the skin is golden brown.
7. Baste Occasionally: Halfway through baking, spoon some of the pan juices over the chicken to keep it moist and flavorful.
8. Let Rest: Once cooked, remove from the oven and let the chicken rest for about 5 minutes to allow the juices to redistribute.
9. Garnish and Serve: Sprinkle fresh cilantro on top before serving for an added flavor boost.
