US-based fast food restaurant brand White Castle has added French Toast Sliders and Cheddar Cheese Rings to its all-day menu offerings.

The company added that the two items will be rolled out for a limited time period.

White Castle vice-president Jamie Richardson said: “White Castle has been innovating for more than 100 years, starting with the Slider that remains an inspiration for Cravers everywhere.

“We are fortunate to have the best restaurant operations leaders in the business and we can't wait to serve up these new additions to our Anything, Anytime menu. But come and try 'em quick – they are here for a limited time only.”

The new French Toast Slider features slices of cinnamon swirl French toast bookend a freshly cracked egg.

It is offered to the guests with American cheese and the choice of savoury sausage or hickory smoked bacon.

White Castle’s said that its new Cheddar Cheese Rings are Crispy from the outside and are filled with creamy cheddar cheese.

Customers can purchase them in three, five and ten pieces.

White Castle Product Innovation director Chef Phillip Bach said: “As a culinary team, we believe innovation can start by looking at something people love and considering how to deliver it in a new way.

“In this instance, we started with a slider-sized version of French Toast and worked on re-imagining it as a complete breakfast Slider sandwich.

“After testing first with internal team members and then customers, we returned to the kitchen to refine the sandwich to ensure we were serving up a Craveable Slider that people can't get anywhere else.”
