What is a slider burger?

White Castle’s Original Slider is made with 100% beef, and is known for its compact size—about 2 x 2 inches (5 x 5 cm)—earning the nickname “Slider” because of how easily it goes down. Since its debut over a century ago, White Castle’s slider lineup has grown significantly.

Today, the chain offers a wide variety of sliders to suit all tastes, including the Bacon Cheese Slider, Chicken Ring Slider, Double Cheese Slider, and the Breakfast Slider made with fresh eggs. These mini sandwiches are available any time of day—morning, noon, or night.

White Castle Offers

To make National Slider Day even more special, White Castle has launched a new promotion: six Original Sliders for just $4. This offer, available since May 9, brings the price of each slider down to less than 67 cents.

More than two-thirds of White Castle locations are open 24/7, and many others stay open past midnight, allowing customers to enjoy tasty and affordable options at any hour—whether it’s day or night.

History of White Castle

White Castle is known as the first fast-food hamburger chain in the United States, serving its iconic Sliders—small burgers with a big flavor—since 1921. Based in Columbus, Ohio, this family-owned business now operates around 340 restaurants and also offers its famous food in the frozen aisles of grocery stores nationwide. Dedicated to high-quality standards, the company manages every step of its production. It operates its own meat processing plants (Slider Provider), bakeries, and facilities for frozen Slider products.

Over the years, the brand has earned numerous accolades. In 2014, Time magazine named the Original Slider the “Most Influential Burger of All Time.” In 2019, Thrillist awarded the Impossible Slider as the “Best Plant-Based Fast-Food Burger.” And in 2021, Fast Company recognized White Castle as one of the “10 Most Innovative Restaurant Companies.”

The company is also praised for its workplace culture. It was certified as a Great Place to Work for four consecutive years (2021–2024), reflecting the dedication and pride of its team members. The brand’s loyal fan base, known as Cravers, shows its passion annually by competing to enter the Cravers Hall of Fame, celebrating the most devoted White Castle enthusiasts.

What is National Slider Day?

National Slider Day is celebrated every year on May 15, a day when many restaurants offer discounts and special promotions on their popular slider-style burgers. It’s believed that White Castle originated the celebration in May 2015 as a tribute to its iconic Original Slider. A year earlier, in 2014, Time magazine named the Original Slider “the most influential burger of all time”, highlighting its historic impact on the fast food industry.
