Rip the bread and place it in a food processor or blender for a few seconds to make fresh bread crumbs.
Beat the egg in a small dish.
Pour breadcrumbs into a shallow dish and add ½ of the Parmesan cheese and Italian seasoning.
Season chicken cutlets with salt & pepper, then dip into the egg mixture, followed by the breadcrumb mixture.
Place on a large greased baking sheet and spray with cooking spray. Bake for 10 minutes. Top each chicken cutlet with ⅓ cup pasta sauce, ¼ mozzarella cheese, and sprinkle with the remaining Parmesan cheese.
Bake an additional 5-6 minutes or until the chicken reaches 165°F. Do not overcook.
Broil 1 minute to brown the cheese, if desired.
Notes
Note: Chicken cutlets are thin and cook quickly, so watch them closely to check when they are done. A digital meat thermometer works best for this.
If using full chicken breasts, cut them in half horizontally to make thin cutlets.
Low carb or keto bread gives the best results, but if unavailable, use crushed pork rinds instead. Or replace with ¼ cup almond flour.
