Step 1

Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.

Step 2

Combine corn flakes, Parmesan cheese, and ranch dressing mix in a bowl. Dip chicken in melted butter; roll each chicken breast in corn flake mixture until evenly coated. Place coated chicken in the prepared baking dish.

Step 3

Bake in the preheated oven until chicken is no longer pink in the center and the juices run clear, about 45 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
