01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Pat chicken breasts dry. Mix salt, pepper, garlic powder, and smoked paprika in a small bowl. 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 - Mix mayonnaise, sour cream, ranch dressing, garlic powder, and onion powder in a small bowl to create the ranch spread.
05 - Combine panko breadcrumbs, Parmesan, melted butter, provolone, and mozzarella in another bowl.
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 until chicken is cooked through (internal temperature 165°F) and crust is golden and crisp.
09 - Garnish with chopped parsley if desired. Let rest for 2–3 minutes before serving.
