Begin by cutting each chicken breast into three equal pieces.
Place the chicken pieces in a bowl and let them marinate in the refrigerator overnight.
Preheat your oven to 375°F (190°C).
In a small bowl, combine mayonnaise (or Greek yogurt), half of the Parmesan cheese, garlic powder, seasoning salt, and black pepper. Mix until well combined.
Take a baking dish and arrange the marinated chicken pieces evenly.
Spread the mayonnaise mixture over each chicken breast, ensuring they are evenly coated.
Sprinkle the tops of the chicken breasts with the remaining Parmesan cheese.
Bake in the preheated oven for 40 to 45 minutes or until the chicken is cooked through.
Once cooked, remove from the oven and serve this delightful dish to your eagerly awaiting guests or family members.
