Pat the chicken breasts dry with paper towels.
Brush both sides of each chicken breast with olive oil.
In a small bowl, mix garlic powder, paprika, salt, and black pepper.
Sprinkle the seasoning mixture evenly over both sides of the chicken breasts.
Preheat the air fryer to 375°F (190°C) for 3 minutes.
Place the chicken breasts in the air fryer basket in a single layer, making sure they do not overlap.
Cook the chicken breasts for 15 minutes, flipping halfway through at 7-8 minutes.
Check the internal temperature with a meat thermometer; it should read 165°F (74°C).
If the chicken has not reached the proper temperature, cook for an additional 2-3 minutes and check again.
Remove the chicken breasts from the air fryer and let rest for 5 minutes before slicing and serving.
