Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with aluminum foil.

Combine Italian bread crumbs, panko bread crumbs, Parmesan cheese, seasoning salt, pepper, and garlic powder in a bowl.

Combine spicy ranch dressing and buttermilk ranch dressing in a separate bowl. Dip chicken into dressing until both sides are coated, then coat in bread crumb mixture. Place chicken in a single layer on the prepared baking sheet, leaving space between pieces. Lightly drizzle chicken with melted butter.

Bake in the preheated oven until chicken is no longer pink in the center and the juices run clear, 30 to 35 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
