White Castle introduced National Slider Day in May 2015 to honor the iconic, steamed-grilled-on-a-bed-of-onions hamburger. The Original Slider is well-known for its hot, juicy flavor, but the 100% beef patties are equally popular for their 2-by-2 inch size. This makes it easy to eat, and it is also highly regarded.

Here are some more facts about White Castle sliders.

  • White Castle’s founder invented the slider in 1921. He used a spatula to smash a meatball onto a griddle.
  • White Castle introduced square sliders in 1954 to maximize the griddle area.
  • White Castle also added five holes in the slider pat that year to help it absorb the flavors of the grilled onions.
  • White Castle introduced Cheese Sliders to its standard menu in 1962, 40 years after the original slider was first served.
  • The Original Slider was named by Times magazine as the “most influential burger” in 2014.

National Slider Day is right in the middle of National Hamburger Month. This White Castle creation was created to honor the pioneering fast-food hamburger industry.
