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. Brush both sides of each breast with olive oil and season 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 to 4 minutes per side until golden brown. 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. Spread the mixture evenly over the top of each chicken breast.
05 - In a separate bowl, mix panko breadcrumbs, melted butter, and grated Parmesan cheese. Sprinkle generously over the Parmesan crust layer on each breast.
06 - Bake for 12 to 15 minutes until the chicken is cooked through to an internal temperature of 165°F and the topping is golden and bubbly.
07 - Let the chicken rest for 2 minutes before serving. Pairs well with mashed potatoes or a fresh garden salad.
