Preheat the air fryer to 380°F.
In a small bowl, mix together garlic powder, onion powder, smoked paprika, salt, and black pepper.
Pat the chicken breasts dry with paper towels. Rub the olive oil over the chicken, then coat both sides with the spice mixture.
Place the chicken breasts in the air fryer basket in a single layer. Cook for 10 minutes.
After 10 minutes, flip the chicken breasts and brush BBQ sauce on top. Cook for an additional 5-7 minutes, or until the internal temperature reaches 165°F.
Remove the chicken from the air fryer and let it rest for 5 minutes before slicing. Serve with extra BBQ sauce if desired.
