What is the new White Castle slider made of? The restaurant chain adds a 1920s-inspired burger to its permanent menu

White Castle is paying homage to its very first burger by permanently adding it to its menu as “The 1921 Slider”.

This rollout celebrates 101 years of what is widely recognized as the world’s first hamburger fast food chain, which opened in September 1921.

The 1921 Slider is considered “the franchise’s most significant product innovation since adding a slice of cheese to its Sliders in 1962”. It dates back to the 1920s with the accompanying Coca-Cola Cream Soda.


White Castle’s ‘The 1921 Slider’ adds some twists to the original 1921 burger

The 1921 Slider is just White Castle’s fourth innovation since the turn of the century, a testament to its approach – “If it ain’t broke, don’t fix it.”

However, when the brand aims for innovation, it comes out with guns blazing. His pioneering Impossible Slider, released in 2018, was the first of its kind in the fast food industry.

In a press release announcing the launch of the Slider 1921, Lynn Blashford, Marketing Director of White Castle, said:

“The 1921 Slider closes the loop from our menu to the burger that started it all. It has been so popular in our limited release that we can’t wait for Cravers in all of our foodservice markets to take advantage of this new version of our 101-year-old old slider recipe.”

The sturdy slider does away with the chain’s signature square patties, returning to its original thicker, round beef patties.

The perfectly seared patty is then topped with cheddar cheese, grilled caramelized onions, a slice of Roma tomato, pickles and, first, lettuce.

Blashford added:

“We’re thrilled to offer our customers this additional menu option that reminds us of our early days. Although we’ve made many updates over 10 decades, the all-new 1921 Slider comes closer than ever to that very first slider. with some new twists.”

White Castle began market trials of the 1921 Slider in Cincinnati last year. Boosted by positive reviews, the product was introduced in St. Louis, Nashville and Louisville. The slider has already appeared in a number of states, but New York will have to wait until June to get a taste of this special burger.

Lisa Ingram, CEO of White Castle and a fourth generation member of the Ingram family, said in a press release:

“My great-grandfather had many brilliant ideas when he started White Castle in 1921 and in the decades that followed. Thanks to him, innovation has been part of our DNA from the very beginning, and he would so happy to see that our team members’ drive for innovation is stronger than ever.”

The fast-food chain‘s nostalgic efforts don’t end with the 1921 Slider. Their retro Coca-Cola Creme Soda was introduced only to complement the burger. The drink was the only soda on the menu alongside the chain’s handful of other offerings in 1921.

Coca-Cola Cream Soda, marketed as the classic Coke flavor paired with just the right amount of rich cream soda, could also consider a more substantial version.
