01 - Preheat oven to 400°F. Line a baking sheet with aluminum foil or parchment paper.
02 - Pound chicken breasts lightly to an even thickness for uniform 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 the chicken for 3 to 4 minutes per side until a golden crust forms. Do not cook through. Transfer the seared chicken 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 this mixture evenly over the top of each seared chicken breast.
05 - In a separate bowl, toss panko breadcrumbs with melted butter and grated Parmesan cheese until the crumbs are evenly coated. Sprinkle the mixture generously over the Parmesan crust layer on each chicken breast.
06 - Bake for 12 to 15 minutes, until the chicken reaches an internal temperature of 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.
