Panko Breaded Fish Slider FAQs

What kind of fish does White Castle use for the Panko Fish Slider? ▼

White Castle uses 100% wild-caught Alaska pollock fillets coated in coarse Japanese-style panko breadcrumbs and fried golden in 100% vegetable oil.

Is the Panko Breaded Fish Slider available year-round or only during Lent? ▼

Yes, the Panko Breaded Fish Slider and Fish Nibblers are permanent, year-round menu items at White Castle, whereas Shrimp Nibblers and Clam Strips rotate onto the menu as seasonal Lenten seafood specials each spring.
