Fast-food hamburger chain White Castle is introducing the newly formulated plant-based Impossible Slider recipe at all menus at its restaurants across the US.
The fast food chain initially introduced the Impossible Slider on 12 April last year at 140 restaurants in New York, New Jersey and Chicago. This was later released to 13 states across the country in September 2018.
White Castle has upgraded the menu item for the latest launch and introduced it at CES 2019 in Las Vegas, Nevada. According to the company, the new recipe is a source of ‘high quality protein’ and is available to customers for $1.99.
White Castle vice-president Jamie Richardson said: “As a 98-year-old family-owned business, White Castle has a number of milestones that are very important to us.
“But the launch of the Impossible Slider is particularly special because of the immediate impact it had. Adding this burger made from plants has been a huge leap in establishing White Castle as a slider provider for all tastes and preferences.
“Now that we’ve accomplished what many thought was impossible, we can’t wait to see how customers respond to an even juicier, beefier and tastier version.”
In addition, the restaurant chain is experimenting with Impossible Slider to offer it in different flavour combinations.
In January this year, White Castle added the plant-based burger to its menu at three locations in Las Vegas.
Called the White Castle Impossible Slider, the vegetarian burger is made from cheese, pickles and onions, and is available in White Castle’s Strip, Downtown, and Jean stores.
