Preheat the oven to 420 degrees F. Combine the parmesan cheese with seasoned breadcrumbs.
Melt the butter, and using a brush, coat the chicken breasts on both sides.
Dip the chicken breast in the breadcrumb mixture and place it on a flat plate.
Line a tray with baking paper and place the chicken breasts. Spray oil on top and bake for 20 minutes.
