Place the almonds in a food processor and pulse until fine crumbs form. Scrape the almond crumbs into a shallow bowl, then mix in the Parmesan cheese, onion powder, paprika, parsley, salt and pepper.

Place the egg in a separate shallow bowl and beat with a whisk. Pat the chicken dry with paper towels, then working with one cutlet at a time, dip in the egg. Let the excess egg drip off of the cutlet, then dip in the almond mixture, pressing the crumbs onto each side of the cutlet to ensure that they adhere. Place the coated cutlet on the prepared sheet pan. Repeat the process with the remaining chicken.

Spray the chicken with more nonstick cooking spray, then bake for 18-20 minutes, flipping the chicken halfway through cooking time, or until the cutlets are cooked through and the almond mixture is golden brown and crisp.
