I could have called these Cornflake-Crunchy Chicken Cutlets as the crisp coating is provided not by breadcrumbs, but by cornflakes. Take the chicken out of the fridge so that it isn’t too cold ...

Transfer onions to a plate, rinse and wipe skillet clean. Season chicken cutlets with onion powder, salt, remaining 1 teaspoon thyme, and remaining 1/4 teaspoon pepper. Place flour in a shallow dish.
