Step 1

Place a rack in the center of the oven and preheat to 425 degrees. Spray a baking sheet with cooking spray then set aside.

Step 2

Rinse the chicken breasts under cool water, pat dry with paper towels and place them on the baking sheet. Sprinkle each lightly with salt and pepper then set aside.

Step 3

In a small bowl, stir the mayonnaise, Parmesan cheese, pepper, garlic powder, green onion and parsley together until well combined. Spread an equal amount of the Parmesan cheese mixture evenly over the top surface of each chicken breast then bake 20–22 minutes, depending upon thickness—the thickest part of the chicken should register 165 degrees on a meat thermometer.

Step 4

Once cooked, remove from oven and allow the crust to set 5 minutes before transferring to a serving dish. Enjoy!
