Preheat the oven to 375 degrees Fahrenheit and spray a 9 x 13-inch baking dish with nonstick cooking spray.
In a bowl, mix 1 cup light mayonnaise, ½ cup freshly grated parmesan cheese, 1 ½ teaspoons seasoning salt, 1 teaspoon garlic powder, and ½ teaspoon ground black pepper.
Place the 6 chicken breasts in the prepared baking dish and coat each piece with the mayonnaise mixture. Sprinkle the remaining ½ cup of parmesan cheese over the top of the coated chicken. Cover with aluminum foil and bake for 20 minutes.
Remove the foil and bake for another 15 minutes, until the chicken reaches an internal temperature of 165 degrees Fahrenheit and the cheese is browned.
Remove from the oven, garnish with fresh parsley, and serve warm.
