White Castle is entering the chicken sandwich competition with a new menu item. The fast-food chain aims to challenge other brands in the fight for the best crispy chicken sandwich.
Jamie Richardson, White Castle’s vice president of marketing and public relations, announced the launch during the National Restaurant Association conference in May 2025. The new chicken sandwich will be available nationwide starting June 16.
The sandwich features extra-crispy buttermilk-fried chicken. It is topped with a sweet and tangy honeycomb mustard. The sandwich is served on White Castle’s signature buns. Customers can also add lettuce and tomato for an extra charge.
“We are introducing a bigger and crispier chicken sandwich,” Richardson said. “It tastes better and is more crave-worthy. Our secret advantage is the size of our sandwiches and sides. They are smaller, so they are easier to share. Having cheese sliders alongside chicken sandwiches makes a perfect meal.”
Richardson added that the company tested many options before deciding on the honeycomb mustard. “Customers really liked it. It has all the great flavors you expect from a crave-worthy Castle. It will be coming soon to White Castle locations everywhere.”
White Castle also announced plans to offer more value to customers this summer. The brand will provide money-saving deals alongside its focus on fresh and fast food.
The deals start during Memorial Day weekend and continue through Labor Day. Coupons are available on White Castle’s social media channels and website.
