Prepare the chicken by patting it dry.
In a bowl, mix olive oil, garlic powder, paprika, oregano, salt, and pepper.
Coat the chicken breasts with the marinade and allow them to sit for 5 minutes.
Place the seasoned chicken in the air fryer basket.
Cook for 12 minutes, flipping halfway through.
Check for doneness using a meat thermometer.
Allow the chicken to rest for 5 minutes before slicing.
