Prepare the Marinade: In a mixing bowl, combine olive oil, ground cumin, paprika, coriander, turmeric, garlic powder, onion powder, cinnamon, ginger, lemon juice, salt, and pepper. Whisk everything together until well combined.
Marinate the Chicken: Place the chicken thighs into the bowl with the marinade, ensuring that all pieces are well-coated. Cover the bowl with plastic wrap and let it marinate in the refrigerator for at least one hour, or overnight for deeper flavor.
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C). This ensures that the chicken will cook evenly and crisp up perfectly.
Cook the Chicken: Once preheated, place the marinated chicken thighs into the air fryer basket in a single layer. Cook at 375°F (190°C) for 20-25 minutes, flipping halfway through the cooking time. The chicken should be golden brown and crispy on the outside while remaining juicy inside.
Rest and Serve: Once the chicken is cooked, remove it from the air fryer and let it rest for a few minutes. Slice the chicken into thin strips and garnish with fresh parsley if desired. Serve with pita bread, rice, or a fresh salad.
