White Castle celebrates their self-created holiday–National Slider Day–on May 15, 2023 by offering anyone who stops by a free Cheese Slider at participating locations (no purchase necessary).
To take advantage of the freebie, you’ll need to show a digital coupon that can be found on the White Castle website.
White Castle’s Cheese Slider is the chain’s Original Slider with the addition of cheese. As such, it consists of a beef patty steamed on a bed of onions topped with a choice of American, Jalapeno, or Smoked Cheddar cheese and served on a steamed slider bun.
