01 - Preheat oven to 400°F (200°C).
02 - Combine olive oil, lemon juice, ground cumin, ground coriander, smoked paprika, ground cinnamon, ground turmeric, cayenne pepper, minced garlic, salt, and black pepper in a large mixing bowl. Mix until well blended.
03 - Add chicken thighs to the marinade and coat thoroughly. Cover and marinate for at least 30 minutes or up to overnight in the refrigerator for more depth of flavor.
04 - Line a baking sheet with parchment paper or foil. Remove chicken from marinade and arrange thighs skin-side up in a single layer on the prepared sheet.
05 - Roast in the preheated oven for 35 minutes, until skin is crisp and meat is fully cooked. The internal temperature should reach 165°F (74°C).
06 - Remove chicken from oven and let rest for 5 minutes. Sprinkle with chopped cilantro and serve with lemon wedges.
07 - Present hot alongside couscous, rice, or flatbread as desired.
