Put the chicken breasts that have been seared into the baking dish. Over the chicken, pour the leftover marinara sauce.
On top of the chicken, sprinkle the grated Parmesan and shredded mozzarella.
Cook the chicken for 20 to 25 minutes in a preheated oven, or until it's cooked through and the cheese has melted and browned.
To let the flavors to combine, set it alone for a few minutes before serving.
Changes and Hints
To get a variety of tastes, feel free to combine various cheeses. You may use a combination of provolone and mozzarella, or you can add some sharp cheddar for a more robust flavor. Add some red pepper flakes to the Italian seasoning if you're looking for a little heat. To add extra vegetables without drawing attention to yourself, try layering sliced bell peppers or spinach beneath the cheese.
