Prep the Chicken: Pat the chicken dry with paper towels to remove excess moisture (this helps it get crispy). In a large bowl, drizzle the chicken with olive oil and toss to coat evenly.
Season the Chicken: In a small bowl, combine garlic powder, onion powder, smoked paprika, thyme, salt, pepper, and cayenne pepper. Sprinkle the seasoning mix over the chicken, ensuring it's well coated on all sides.
Air Fry: Preheat the air fryer to 380°F (193°C) for 3 minutes. Place the chicken pieces in a single layer in the air fryer basket (do not overcrowd).
Cook at 380°F (193°C) for 20-25 minutes, flipping halfway through. Internal temperature should reach 165°F (74°C) for doneness. If using drumsticks or thighs, cook for an additional 2-3 minutes if needed for extra crispiness.
Rest and Serve: Let the chicken rest for 5 minutes before serving. Garnish with chopped parsley or a squeeze of lemon juice (optional).
