Step 1

Preheat oven to broil. Sprinkle chicken breasts with salt and pepper. Heat oil in a large (12-inch) nonstick skillet over medium-high. Cook chicken until a thermometer inserted in the thickest portion of each breast reaches 160°F, about 8 minutes per side. Place chicken on a baking sheet lined with aluminum foil.

Step 2

Stir together ranch dressing and 2 tablespoons of the Parmesan in a small bowl. Spread ranch mixture evenly over each chicken breast. Place 1 provolone slice over each breast.

Step 3

Stir together panko, melted butter, and remaining 4 tablespoons Parmesan in a small bowl. Sprinkle mixture evenly over provolone on each breast. Broil until cheese is melted and panko is golden brown, about 2 minutes. Remove from oven, and sprinkle with chopped parsley.
