Step 1

In a large bowl, combine the ranch dressing and chicken breasts. Toss to coat evenly. Cover and refrigerate for at least 30 minutes or up to a few hours for a more intense flavor.

Step 2

Preheat oven to 350°F. Grease a baking sheet with vegetable oil.

Step 3

In a shallow dish, mix together the panko breadcrumbs and grated Parmesan cheese.

Step 4

Remove the chicken from the marinade, allowing excess dressing to drip off. Dip each chicken breast into the panko-Parmesan mixture, pressing to coat evenly on all sides. Gently toss between your hands so any breadcrumbs that haven't stuck can fall away. Arrange the coated chicken onto the prepared baking sheet.

Step 5

Bake in the preheated oven until the chicken is no longer pink in the center, and the juices run clear, about 30 minutes. An instant-read thermometer inserted into the center should read at least 165°F.

Step 6

Remove from the oven and let the chicken rest for 5 minutes before serving. Enjoy!
