Prepare the chicken: Ensure the cavity is empty and pat the chicken dry thoroughly with paper towels to help the skin crisp up.
Season: Rub the chicken all over with olive oil, then coat evenly with the seasoning mix (or your preferred chicken seasoning).
Air fry breast-side down: Place the seasoned chicken breast-side down in the air fryer basket. Set the air fryer to 350°F (175°C).
Cook for 30 minutes: Air fry the chicken for 30 minutes to begin the crisping process.
Flip and continue cooking: Carefully flip the chicken breast-side up and continue to air fry for another 20 to 30 minutes. The internal temperature should reach 165°F (74°C) in the thickest part of the meat.
Rest before serving: Remove the chicken from the air fryer and let it rest for 10 minutes before carving to allow juices to redistribute.
