Preheat oven to 425⁰F. Grease an 8x8 pan. Set aside.
Put a large pan on medium heat. When warm, spray cooking oil into the pan and add cutlets. Brown on each side for 1.5-3 minutes.
Lay down chicken cutlets in the 8"x8" pan. It might be a tight squeeze, but they will fit.
Add marinara sauce on top. Put cheese on top of sauce.
Place into the oven for 20 minutes, or until cheese is bubbly and the internal temperature of the dish is at least 165⁰F.
If you want crispy cheese, turn oven to broil and place the pan below the heat. Allow to cook until cheese is brown and bubbly, about 2-3 minutes.
Allow dish to cool slightly before serving. Do not allow to sit for too long; the breading on the inside can be prone to becoming soggy.
