Pat the chicken breasts dry with a paper towel. If they're uneven in thickness, pound them gently so they cook evenly.
Rub the chicken breasts with olive oil, then sprinkle both sides with garlic powder, paprika, onion powder, salt, and pepper.
Preheat your air fryer to 380 degrees F. Place the chicken breasts in a single layer in the basket and cook for 10 to 12 minutes, flipping halfway through, until the internal temperature reaches 165 degrees F.
Let the chicken rest for 3 to 5 minutes before slicing. This keeps the juices locked in instead of ending up on your cutting board.
