Inspired by the very first hamburger White Castle made when it opened its doors in 1921, the 1921 Slider features a thick, 100 percent beef patty, seared and seasoned, then topped with cheddar cheese, grilled caramelized onions, a slice of Roma tomato, lettuce and pickles on the brand’s signature bun.
In addition to the new Slider, White Castle is also introducing a new soft drink option from Coca-Cola to complement the new 1921 Slider. New Coca-Cola Crème Soda features a blend of creme soda with Coca-Cola and can be found exclusively at White Castle before anywhere else.
To celebrate the launch of the new 1921 Slider, members of the brand’s Craver Nation loyalty program can access a special buy-one-get-one-free offer for The 1921 Slider through the White Castle app. The offer is good for new and existing Craver Nation members and will be available systemwide through May 30, 2022, with the exception of New York and New Jersey.
It’s also worth noting that White Castle restaurants in New York will begin offering The 1921 Slider in June 2022.
