Preheat your air fryer to 375°F (190°C) for 3 to 5 minutes.
Pat the chicken breasts dry with paper towels. If they are thick, pound them to an even thickness.
In a small bowl, combine the olive oil, garlic powder, onion powder, paprika, Italian seasoning, salt, black pepper, smoked paprika, dried parsley, and lemon juice.
Rub the seasoning mixture evenly over both sides of the chicken breasts.
Place the chicken breasts in the air fryer basket in a single layer, leaving space between them.
Air fry for 10 minutes, then flip the chicken.
Continue cooking for 8 to 10 minutes, or until the internal temperature reaches 165°F (74°C).
Remove the chicken from the air fryer and let it rest for 5 minutes before slicing.
Garnish with fresh parsley and serve immediately.
