White Castle sources certified sustainable wild Alaska Pollock for its signature fish fillets. Encased in crunchy Japanese panko breadcrumbs, fish sliders are served with melted American cheese and paired with custom zesty tartar or tangy cocktail sauces.
Sourced directly from the icy, pure waters of the Bering Sea and Gulf of Alaska, ensuring maximum freshness, tender flaky meat, and environmentally responsible fishing standards.
Unlike dense beer batter, White Castle coats each fillet in airy panko breadcrumbs, creating a light, shatteringly crisp outer crust that resists sogginess inside the steam bun.
Pair your fish or shrimp nibblers with complimentary squeeze packets of White Castle Creamy Tartar Sauce or bold Horseradish Cocktail Sauce on the sauces and condiments guide.
