In a small bowl, mix together the parmesan cheese, breadcrumbs, garlic, Italian seasoning, salt and pepper.
Dip the top of each chicken breast into the melted butter, then press the top of the chicken into the breadcrumb mixture to coat.
Place the chicken breasts on the prepared sheet pan.
Scatter the potatoes around the chicken. Drizzle the remaining butter over the potatoes and chicken. Season the potatoes with salt and pepper.
Bake for 25-30 minutes or until chicken is cooked through and potatoes are tender. Cook time may vary depending on the thickness of your chicken.
