Pre-heat oven to 375 and lightly spray a cookie sheet with cooking spray
Pour the ranch dressing and dry bread crumbs onto two separate plates. I like to use pie plates.
Dip your chicken into the dressing to coat it, and then coat with the bread crumbs.
Bake for 35-45 minutes until the outside is golden brown, and the thickest parts are no longer pink when cut. **DO NOT turn the chicken while it's cooking. This will cause the breading to fall off.
Notes
You can also add 1/4 to 1/2 of a powder ranch packet to the bread crumbs for extra seasoning.
