01 - Preheat oven to 400°F. Line a baking sheet with aluminum foil or parchment paper.
02 - Flatten chicken breasts lightly for even cooking. Brush both sides of each breast with olive oil, then season generously with garlic powder, onion powder, paprika, salt, and black pepper.
03 - Heat a grill pan or skillet over medium-high heat. Sear chicken for 3–4 minutes per side until a golden crust forms. Do not cook through. Transfer seared breasts to the prepared baking sheet.
04 - In a small mixing bowl, combine mayonnaise, sour cream, grated Parmesan cheese, shredded provolone cheese, and dried Italian herbs. Stir until well blended. Spread the mixture evenly over the top of each seared chicken breast.
05 - In a separate bowl, mix panko breadcrumbs, melted butter, and grated Parmesan cheese until evenly combined. Sprinkle the topping generously over the Parmesan crust layer on each breast.
06 - Bake for 12–15 minutes until the internal temperature of the chicken reaches 165°F and the topping is golden and bubbly.
07 - Remove from the oven and let the chicken rest for 2 minutes before serving. Pair with mashed potatoes or a fresh garden salad.
