Using only 6 ingredients, this chicken comes together in no time, but is packed with flavor!
In a small bowl, combine the mayonnaise, parmesan cheese, seasoning salt, black pepper, and garlic powder.
Spread the mixture evenly on top of the chicken breasts.
Place chicken into a baking dish and bake in preheated oven, 375 degrees, for about 45 minutes, or until cooked through.
Remove from oven and serve!
