Start by slicing the chicken breasts in half horizontally to create thin cutlets. I season both sides with salt and pepper so the flavor goes all the way through. This step makes a huge difference in taste.
I place flour in one bowl, beaten eggs in another, and panko mixed with Parmesan in the third. Dredge the chicken in flour, dip it in egg, then coat it well in breadcrumbs. Press gently so the coating sticks.
Heat olive oil in a large skillet over medium heat. Fry the chicken for about 3–4 minutes per side until golden and crispy. I transfer the chicken to a paper towel-lined plate to remove excess oil.
I spread a thin layer of marinara sauce in a baking dish and place the fried chicken on top. More marinara goes over each piece, followed by slices of fresh mozzarella. This layering keeps everything moist.
Bake in a preheated oven at 400°F (200°C) for about 15 minutes. The cheese should melt and bubble without burning. I finish it with fresh basil right before serving.
