US-based hamburger restaurant chain White Castle has announced the re-launch of its Sloppy Joe Sliders and Mac & Cheese Nibblers for a limited time.

The new additions are being offered across White Castle restaurants throughout the winter season, until 4 February 2024. 

White Castle’s seasonal Sloppy Joe Sliders product includes three sliders – Sloppy Joe, Smoky Joe and Spicy Joe. 

Available for $1.19, the Sloppy Joe Slider is made with lean ground beef, onions, tomatoes and bell peppers.

The Smoky Joe is an extension of the Sloppy Joe topped with cheddar cheese and crispy onions, while the Spicy Joe features spicy jalapeño cheese and jalapeño crisps.

Customers can purchase Smoky and Spicy Joe Sliders at $1.49 each.

White Castle is also offering the "Joe six-pack" for $6.99, allowing customers to mix and match any six sliders.

Mac & Cheese Nibblers are made by combining cheddar cheese and macaroni and coating with a crispy batter.

It is available in three sizes – small with five nibblers, a medium 12 nibblers pack or a sack of 20 nibblers.

White Castle vice-president Jamie Richardson stated: “There are certainly times when neatness is required, but this is the season when it's perfectly reasonable to be comforted with all things sloppy.

“Our line-up of Sloppy Joe Sliders strikes the right balance of comfort, flavour and crave-ability.”

Founded in 1921, White Castle is a Columbus, Ohio-based family-owned business.

It owns and operates 350 restaurants and a retail division.

In August 2023, White Castle announced the addition of two new offerings, French Toast Sliders and Cheddar Cheese Rings, to its all-day menu.
