Chicken Pizzaiola

3 cups tomato sauce, homemade or jarred
4 boneless, skinless chicken breasts
2 ounces (1 cup) Parmesan cheese, grated
4 ounces (1 cup) mozzarella, shredded
2 ounces pepperoni, sliced thin

Adjust an oven rack to the middle position and preheat to 450 F. Spread the tomato sauce in a 9x13-inch baking dish.

Pat the chicken dry with paper towels and season with salt and pepper. Spread the Parmesan in a shallow dish, then add the chicken, turning to coat. Lay the chicken on top of the tomato sauce. Bake for 15 minutes.

Remove the chicken from the oven and sprinkle the mozzarella and pepperoni over it. Increase the oven temperature to 475 F and continue to bake until the cheese melts and the chicken is cooked through (an instant read thermometer should read 160 F), about 5 more minutes.
