Set the oven temperature to 425 degrees.
Place a cooking rack on top of a baking sheet that has been lined with parchment paper.
Put mayo, Dijon mustard, and a few pinches of salt and pepper in a shallow bowl.
Put the Panko breadcrumbs, Parmesan, Italian seasoning, garlic powder, paprika, and a few generous pinches of salt and pepper in a separate shallow bowl.
Coat the chicken on both sides by tossing it in the mayonnaise mixture.
Gently press the breadcrumb mixture into the chicken after dredging it in it.
On a baking sheet with a wire cooling rack on top or on a pizza pan with holes, arrange the chicken about an inch apart.
Apply cooking spray with olive oil.
Bake for 20 to 25 minutes, or until the breadcrumbs are rich golden brown and the chicken is cooked through.
If desired, garnish with parsley, cut into slices, and savor!
