About National Slider Day
Ends: May 15, 2025
DESCRIPTION:
National Slider Day celebrates the two-inch circumference mini sandwich invented by White Castle nearly a century ago. Typically a slider is a small hamburger, but it can be any type of round-roll mini sandwhich.
The Library of Congress states the first hamburger sold in America was in 1900 by Louis Lassen, a Danish immigrant, and restaurateur in New Haven, Connecticut. White Castle hamburger chain states the hamburger is the invention of Otto Kuase of Hamburg, Germany. White Castle began in 1921.
Who created the ground meat sandwich may never be known. The US government gives Lassen official credit because the first sale can be proved.
What is known is that in 1904 at the St. Louis World's Fair, the humble hamburger sandwich caught the attention of the New York Tribune, gaining instant celebrity in American culture. Later, Roy Kroc would make hamburgers the definition of fast food affordable to the masses.
During both World Wars, due to Germany being the enemy, restaurants referred to the beef patties as Salisbury steak, a hamburger patty without the buns drenched in gravy.
Sliders are now a popular appetizer and can be found in most areas with local influences. This event was first celebrated in 2014.
