01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or grease lightly.
02 - Pat chicken breasts dry with paper towels. Combine salt, pepper, garlic powder, and smoked paprika in a small bowl. 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 prepared baking sheet.
04 - Whisk together mayonnaise, sour cream, ranch dressing, garlic powder, and onion powder in a small bowl until smooth and fully combined.
05 - Combine panko breadcrumbs, grated Parmesan, melted butter, shredded provolone, and shredded mozzarella in a separate bowl. Mix until butter evenly coats crumbs.
06 - Spread approximately 1 tablespoon of ranch mixture evenly over the top of each seared chicken breast.
07 - Press Parmesan breadcrumb mixture generously onto each chicken breast, lightly pressing to adhere to the ranch layer.
08 - Bake for 15 to 18 minutes until chicken reaches internal temperature of 165°F and crust turns golden brown and crispy.
09 - Remove from oven and let chicken rest for 2 to 3 minutes before serving. Garnish with fresh chopped parsley if desired.
