Preheat your oven to 375°F and grease a baking dish like you mean it.
Pat those chicken breasts dry — nobody likes soggy seasoning.
In a bowl, stir together the mayo (or yogurt), Parmesan, garlic powder, onion powder, paprika, salt, and pepper.
Slather that creamy mixture generously over the tops of each chicken breast. Don’t be shy.
Pop them into the oven and bake for 25–30 minutes, or until the internal temperature hits 165°F and the tops are golden.
Let them rest a few minutes before serving. Trust me, it’s worth the wait.
Sprinkle with chopped parsley if you want to impress someone.
