The secret to truly crispy Chicken Kiev lies in a robust, multi-layered breading and a precise cooking method. Apply a firm breading of seasoned flour, egg wash, and Panko crumbs to create a sealed, insulating crust. Then, deep-fry at 170-175°C to set the crisp exterior, followed by a short bake to ensure thorough cooking and melted butter without rupture, maintaining the crust's integrity.
