01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper and set aside.
02 - Place chicken breasts between two sheets of plastic wrap. Using a meat mallet or rolling pin, pound to an even 1/2-inch thickness for uniform cooking.
03 - Arrange three shallow bowls: place flour in the first, beaten eggs in the second, and combine panko, 1/2 cup Parmesan, oregano, garlic powder, salt, and pepper in the third.
04 - Dredge each chicken breast in flour, shaking off excess. Dip into egg mixture, then press firmly into panko mixture to coat evenly on all sides.
05 - Heat 1/4 cup olive oil in a large skillet over medium-high heat. Fry chicken breasts for 3-4 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to prepared baking sheet.
06 - Spread a thin layer of marinara sauce over each chicken breast. Top evenly with mozzarella, remaining Parmesan, and red pepper flakes if desired.
07 - Drizzle with 1 tablespoon olive oil and bake for 10-12 minutes until cheese is fully melted and bubbly with golden spots.
08 - Remove from oven, scatter fresh basil over the top, and let rest for 2 minutes before slicing and serving.
