Prepare the Chicken: If your chicken cutlets are thick, place them between two pieces of plastic wrap and gently pound them to an even thickness of approximately ½ inch using a meat mallet or rolling pin.
Set Up Breading Stations: In a shallow bowl, whisk together the eggs and Dijon mustard until well combined and smooth. In another shallow dish, mix the grated Parmesan cheese, whole-wheat breadcrumbs, garlic powder, Italian seasoning, salt, and pepper until evenly distributed.
Bread the Chicken: Take each chicken cutlet and first immerse it into the egg mixture, allowing any excess to drip off. Next, transfer the cutlet to the Parmesan-breadcrumb mixture and coat thoroughly.
Preheat the Pan: In a large skillet, heat a generous splash of olive oil over medium heat. Wait until the oil is shimmering before adding your cutlets.
Cook the Cutlets: Carefully place the breaded chicken cutlets into the skillet in batches, frying for approximately 4-5 minutes on each side, or until golden brown and reaching an internal temperature of 165°F (75°C).
Drain and Serve: Remove the cutlets from the skillet and lay them flat on a paper towel-lined plate to absorb any excess oil.
Garnish and Serve: Just before serving, sprinkle with freshly chopped parsley.
Notes
For a lighter version, use cooking spray instead of olive oil.
