Preheat the oven to 425 degrees F. Spray a large baking dish with nonstick cooking spray. Gently pound the chicken breasts between two sheets of plastic wrap so the pieces are even in thickness.
Pat chicken dry, then arrange in the pan. Sprinkle with salt and pepper
Mix cream cheese, mayo, Parmesan cheese, garlic powder and paprika in a medium bowl, then spread over chicken breasts. Sprinkle panko breadcrumbs and dried parsley over the cheese mixture.
Bake uncovered for 18-25 minutes. Time will vary based on the size of your chicken breasts. Garnish with fresh minced parsley.
