While your air fryer preheats, mince the 3 garlic cloves finely and zest the lemon, then juice it into a small bowl. In the same bowl, combine the olive oil, lemon zest, lemon juice, ras el hanout, smoked paprika, salt, and black pepper to create a fragrant marinade. Pat the chicken pieces dry with paper towels—this is crucial for better browning and crisping in the air fryer. Add the dried chicken to the marinade and toss thoroughly to coat every piece evenly, then let it sit for 15 minutes to allow the spices to penetrate the meat.
