Place chicken cutlets between plastic wrap and pound to an even 0.5-inch thickness to ensure even cooking.
Set up a standard breading station with three shallow bowls: one containing flour seasoned with salt and pepper; one with beaten eggs; and one with a mixture of Panko, Parmesan, oregano, and garlic powder.
Dredge each chicken cutlet in the flour, shaking off excess, then dip into the egg wash, and finally coat thoroughly with the breadcrumb mixture, pressing firmly to adhere.
Heat vegetable oil in a large skillet over medium-high heat until it reaches approximately 350°F (175°C).
Fry chicken in batches for 3 to 4 minutes per side until the coating is golden brown and the internal temperature reaches 165°F (74°C).
Transfer the fried chicken cutlets to a parchment-lined baking sheet.
Top each cutlet with 3 tablespoons of marinara sauce and a generous portion of shredded mozzarella cheese.
Place the baking sheet under a preheated broiler for 2 to 3 minutes, or until the cheese is melted, bubbling, and slightly browned.
Garnish with fresh basil and serve immediately.
