01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
02 - Pat chicken breasts dry with paper towels. In a small bowl, combine salt, black pepper, garlic powder, and smoked paprika. Rub spice mixture evenly over both sides of each chicken breast.
03 - Heat olive oil in a large skillet over medium-high heat. Sear chicken breasts for 2 to 3 minutes per side until golden brown. Transfer to the prepared baking sheet.
04 - In a small bowl, whisk together mayonnaise, sour cream, ranch dressing, garlic powder, and onion powder until smooth and well combined.
05 - In a separate bowl, combine panko breadcrumbs, grated Parmesan, melted butter, shredded provolone, and shredded mozzarella. Mix until butter is evenly distributed.
06 - Spread approximately 1 tablespoon of the creamy ranch mixture evenly over the top of each seared chicken breast.
07 - Generously mound the Parmesan breadcrumb mixture over each chicken breast, pressing lightly to adhere the crust to the ranch coating.
08 - Bake for 15 to 18 minutes until chicken reaches an internal temperature of 165°F and the crust is golden brown and crispy.
09 - Remove from oven and garnish with chopped fresh parsley if desired. Let chicken rest for 2 to 3 minutes before serving to allow juices to redistribute.
