In a separate bowl, mix together the ingredients, which include mayonnaise or Greek yogurt, parmesan cheese, seasoning salt, black pepper, and garlic powder.
Spread the mixture uniformly over each chicken breast.
Place the chicken into a baking dish and bake in an oven preheated to 375 degrees Fahrenheit for around 45 minutes or until fully cooked.
Once done, remove from the oven and serve immediately.
