White Castle has introduced two new limited-time menu items - a Chicken Fajita Slider and Jalapeño Cravioli. The Chicken Fajita Slider features a crispy chicken patty topped with grilled onions and peppers, jalapeño cheese, and green chili aioli. The Jalapeño Cravioli are fried pockets of cream cheese and diced jalapeños, served with a green chili aioli dipping sauce. Both items are available nationwide through June 14 or while supplies last.

Why it matters

White Castle is known for pioneering fast-food innovations, and these new spicy offerings continue that tradition. The Chicken Fajita Slider brings a Tex-Mex twist to the classic White Castle slider, while the Jalapeño Cravioli puts a unique spin on fried ravioli. These limited-time menu items give customers new reasons to visit White Castle and try something different.

The details

The Chicken Fajita Slider is priced between $2.59 and $2.99, depending on location, making it one of White Castle's more expensive slider options. The Jalapeño Cravioli come in two sizes - a 5-piece order for $1.99 or a 14-piece shareable sack for $4.99. Both automatically include the green chili aioli dipping sauce. The Chicken Fajita Slider features a crispy chicken patty, grilled onions and peppers, jalapeño cheese, and the zesty aioli sauce, all on a traditional White Castle slider bun. The Jalapeño Cravioli have a cornmeal breading and are filled with a creamy blend of cream cheese and diced jalapeños.

• The new menu items launched nationwide on April 6, 2026.
• The Chicken Fajita Slider and Jalapeño Cravioli will only be available through June 14, 2026, or while supplies last.
