Preheat the air fryer to 375°F (190°C) for 5 minutes.
In a medium bowl, combine bread crumbs, grated Parmesan cheese, paprika, garlic powder, onion powder, dried oregano, dried thyme, salt, and black pepper. Mix well.
In a separate shallow bowl, whisk together the egg and water until fully combined.
Pat the chicken breasts dry with paper towels.
Dip each chicken breast into the egg mixture, coating completely.
Place the chicken breast into the bread crumb mixture, pressing gently to coat both sides evenly.
Lightly spray the air fryer basket with cooking spray to prevent sticking.
Place the coated chicken breasts in the air fryer basket in a single layer, ensuring they do not touch.
Lightly spray the tops of the coated chicken breasts with cooking spray to help crisp the coating.
Cook the chicken breasts in the air fryer at 375°F (190°C) for 9 minutes.
Flip the chicken breasts over, spray the other side lightly with cooking spray, and cook for an additional 9 minutes or until the internal temperature reaches 165°F (74°C) and the coating is golden brown and crispy.
Remove the chicken breasts from the air fryer and let rest for 3 minutes before serving.
