01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Pat chicken breasts dry. In a small bowl, mix 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 to create the ranch spread.
05 - In another bowl, combine panko breadcrumbs, Parmesan, melted butter, provolone, and mozzarella.
06 - Spread a tablespoon of the creamy ranch mixture over each chicken breast.
07 - Top each breast generously with the Parmesan breadcrumb mixture, pressing lightly to adhere.
08 - Bake for 15–18 minutes or until the chicken is cooked through (internal temperature 165°F) and the crust is golden and crisp.
09 - Garnish with chopped parsley, if desired. Rest for 2–3 minutes before serving.
