Preheat the oven to 375°F (190°C).
In a mixing bowl, combine mayonnaise, grated Parmesan cheese, garlic powder, onion powder, salt, black pepper, and Italian herbs. Mix well until smooth.
Lightly season both sides of the chicken breasts with a pinch of salt and pepper.
Coat each chicken breast generously with the mayo and Parmesan mixture, ensuring they are fully covered.
Place the coated chicken breasts in a baking dish. Lightly spray the top with cooking spray or drizzle with olive oil for added crispness, if desired.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the top is golden brown.
Remove from the oven and let the chicken rest for about 5 minutes before serving.
For a crispier texture, broil the chicken for an additional 2-3 minutes after baking.
