Step 1

Preheat oven to 400°F.

Step 2

If your chicken breasts are particularly thick and large, cut them in half lengthwise. Working with one chicken breast at a time, place the chicken in between two pieces of wax paper or plastic wrap. Use a meat mallet or rolling pin to pound the chicken to ¼-inch thickness. Generously season both sides of the chicken with salt and pepper. Set aside.

Step 3

Place flour in a shallow bowl and season the flour with salt and pepper. In a separate shallow bowl, combine eggs and garlic salt. In a third shallow bowl, combine breadcrumbs and Parmesan cheese.

Step 4

Working with one piece of chicken at a time, lightly coat both sides of the chicken with the flour, shaking off the excess. Dip the chicken in the egg, shake again, and then coat with the Parmesan breadcrumbs.

Step 5

In a large skillet, heat 1 tablespoon of oil over medium heat. Add 2 pieces of the chicken and cook until the coating is crispy and golden brown, about 3-4 minutes per side. Remove to a sheet pan. Repeat with the remaining 1 tablespoon of oil and 2 chicken breasts.

Step 6

Transfer the sheet pan to the oven and bake until the chicken is cooked through and an instant-read thermometer reads 165°F, about 5-7 minutes.

Step 7

Remove from the oven and spoon marinara sauce on top of each piece of chicken. Sprinkle with mozzarella and return to the oven until the cheese melts, about 2 more minutes.
