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