🍔 The History of Sliders
Updated July 2026
Sliders — small, thin, soft burgers eaten a few at a time — are closely linked to the early standardization of American fast food. But even a food this simple carries a disputed history, especially around where the word "slider" came from.
The small burger and White Castle
The small, square, onion-steamed burger is strongly associated with White Castle, founded in 1921. Selling little burgers cheaply and by the sackful, White Castle helped make the small-format burger a fixture of American eating and pointed the way toward standardized fast food. See our history of fast-food burgers.
Where the word "slider" comes from
The nickname's origin is disputed. One account traces "slider" to U.S. Navy slang for the small, greasy burgers served aboard ship that "slid" down easily. Another simply describes how a soft, small, onion-steamed burger slides down in a bite or two. The term became widely popular in later decades, but pinning down a single first use is difficult.
Sliders today
Today "slider" has broadened well beyond the steamed original to mean almost any mini burger or small sandwich on a soft roll — pulled pork sliders, chicken sliders, party sliders baked in a tray. The word outgrew its origins, much as "burger" did. Make a batch with our sliders recipe.
