Preheat the oven to 350°F (180°C). Set aside a baking sheet and a 9×13-inch baking dish.

Place one chicken breast on a cutting board and cover with wax paper, parchment paper, or plastic wrap. Using a meat mallet, rolling pin, or heavy pan, gently pound the chicken until it is uniformly ½-inch thick. Repeat with remaining breasts.
03 -
Arrange three shallow dishes. In the first, combine flour and ¼ teaspoon salt. In the second, whisk together eggs and milk until frothy. In the third, mix panko breadcrumbs, half the grated Parmigiano-Reggiano, ½ teaspoon pepper, and ¼ teaspoon salt.

Season both sides of each chicken breast lightly with salt and pepper. Dredge each breast first in the flour mixture, shaking off excess; then dip into the egg wash; finally, coat with the breadcrumb mixture, pressing gently to adhere. Place breaded breasts on the prepared baking sheet.

Heat oil in a skillet over medium heat until shimmering but not smoking. Add chicken breasts (in batches if necessary) and cook 3 to 4 minutes per side until golden brown and crispy. Transfer cooked chicken onto a paper towel-lined plate to absorb excess oil.
06 -
Spread approximately 3 cups of warmed marinara sauce evenly over the bottom of the baking dish. Arrange the pan-fried chicken breasts atop the sauce. Spoon a tablespoon of sauce over each breast, then top with fresh basil leaves. Evenly sprinkle remaining Parmigiano-Reggiano over the chicken and place one slice of provolone cheese on each breast.
07 -
Bake uncovered for 15 to 20 minutes until the provolone is golden and an instant-read thermometer inserted into the thickest part registers 165°F (74°C). Remove from oven and serve immediately.
