01 - Whisk together olive oil, lemon juice, garlic, cumin, coriander, paprika, turmeric, cinnamon, ginger, black pepper, cayenne pepper, and salt in a large mixing bowl until well combined.
02 - Add chicken thighs to the marinade, turning to coat completely. Cover and refrigerate for at least 30 minutes or up to 4 hours for deeper flavor penetration.
03 - Preheat oven to 400°F. Arrange marinated chicken thighs on a parchment-lined baking sheet, positioning skin side up.
04 - Roast for 35 minutes until skin is crispy and golden, and internal temperature reaches 165°F when measured with a meat thermometer.
05 - Sprinkle with fresh cilantro and accompany with lemon wedges. Serve immediately with couscous, rice, or flatbread.
