Pat dry the chicken and combine the cajun spices with the salt and pepper, then rub the spices all over the chicken.
Select Air Fry and adjust the temperature to 350°F/180°C and the time 60 Minutes. Preheat until display indicates Add Food.
Spray the air fryer with cooking spray, then place the whole chicken inside. When prompted to Turn Food, turn the chicken over and continue cooking. With 10 Minutes left on the timer, open the tray and turn the chicken over again.
When the cooking program has finished, use a meat thermometer to check the internal temperature of the chicken is at 165°F/75°C. If it isn’t quite to temperature put back in the air fryer for a few more minutes. Let the Air Fryer Roast Chicken rest for 5-10 Minutes before serving.
