Prepare the chicken and marinate it by mixing olive oil, ranch dressing, Worcestershire sauce, white vinegar, lemon juice, and minced garlic in a bowl. Pound chicken breasts to ½ inch thickness, season with salt and pepper, place in a resealable bag, pour the marinade, seal, and refrigerate for 30 minutes or overnight.
Heat oil in a skillet over medium-high heat, sear the marinated chicken for 4-5 minutes on each side until golden brown. Transfer chicken to a baking sheet, cover with foil to keep warm.
Make the Parmesan crust by microwaving a bowl of chopped Parmesan, provolone cheese, and ranch dressing, stirring until melted. Fold in melted butter, garlic powder, and panko breadcrumbs.
Preheat the broiler, spread the cheese mixture on top of the chicken, and broil for 3-4 minutes until bubbly and golden brown.
Serve hot on a platter with sides like mashed potatoes or roasted vegetables.
