Preheat the oven to 425°F. Line a baking sheet with parchment paper.
Slice the chicken breasts in half lengthwise into cutlets. Then, pat the cutlets dry with paper towels. Season both sides with salt and pepper.
In a shallow bowl, combine the breadcrumbs, grated Parmesan, garlic powder, onion powder, oregano, dried basil, and smoked paprika.
Beat the egg in a separate shallow bowl.
Dip each seasoned cutlet into the egg mixture, letting excess drip off, then press into the breadcrumb mixture, coating both sides thoroughly.
Place the coated cutlets on the prepared baking sheet. For extra crispiness, lightly spray the tops with olive oil spray. Then, bake at 425°F for 18-22 minutes, or until golden brown and fully cooked, when the internal temperature reaches 165°F.
Remove from the oven. Spoon marinara sauce over each cutlet and sprinkle with freshly shredded mozzarella cheese. Place a fresh basil leaf under the cheese, or top with fresh chopped basil before serving.
Return the baking sheet to the oven and bake for another 5 minutes, or until the cheese is melted and bubbly. Serve warm, and enjoy!
