Rub the chicken breasts with sesame oil. Sprinkle salt, pepper and the rest of ingredients all over. Pat down and rub gently to ensure even coverage.
Place chicken breasts on the rack inside the air fryer, ensuring some space between the chicken breasts, skin side up.
Plug in your air fryer, set the temperature to 380F and the time to 20 minutes. When the 20 minutes of cooking is up, flip the breasts and continue cooking for another 10 minutes. See notes.
Remove chicken breasts from the air fryer and set on a plate. Let rest for 5 minutes, then serve.
Cooking time will depend on the size of your chicken breasts. Also, some air fryers cook hotter (food positioned closer to the heating element, etc.) so check the temperature after 20 minutes to prevent overcooking.
