Preheat the air fryer to 380°F (193°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, whisk together the olive oil, lemon juice, lemon zest, minced garlic, Italian seasoning, garlic powder, onion powder, paprika, oregano, salt, and black pepper.
Brush or spoon the lemon mixture over both sides of the chicken breasts, coating them evenly.
Place the chicken breasts in the air fryer basket in a single layer, leaving space between each piece.
Air fry for 10 minutes, then flip the chicken and brush with any remaining lemon mixture.
Continue cooking for 8 to 10 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Let the chicken rest for 5 minutes before serving.
Garnish with fresh parsley and serve with fresh lemon slices if desired.
