Preheat the oven to 350ºF and line a sheet pan or baking dish with parchment paper.
Place the chicken breasts on the prepared sheet pan, leaving an inch or more of space in between each one. Set aside.
Add the mayonnaise, parmesan cheese, salt, basil, oregano, thyme, garlic powder, and black pepper to a small bowl.
Mix the mayo, parmesan, and seasonings together until well combined.
Spread the mayo and parmesan mixture on top of each of the chicken breasts in an even layer.
Top with additional parmesan cheese if desired.
Bake the chicken in the preheated oven for 40-45 minutes, or until the juices run clear and the internal temperature reaches a minimum of 165ºF at the thickest part.
For an ultra-crispy topping, finish by broiling for 1-2 minutes.
