01 - Preheat the oven to 400°F.
02 - In a large bowl, combine olive oil, lemon juice, cumin, coriander, smoked paprika, cinnamon, turmeric, cayenne, garlic, salt, and pepper. Mix well to create a smooth marinade.
03 - Add the chicken thighs to the bowl and toss to coat thoroughly. Cover and let marinate for at least 30 minutes, or refrigerate overnight for deeper flavor development.
04 - Line a baking sheet with parchment paper or foil. Arrange the chicken thighs skin-side up, ensuring even spacing for proper heat circulation.
05 - Roast in the preheated oven for 35 minutes, or until the skin is crispy and golden brown. The chicken is done when an internal temperature of 165°F is reached.
06 - Remove from the oven and let the chicken rest for 5 minutes to allow juices to redistribute. Garnish with chopped fresh cilantro and lemon wedges before serving.
