May is National Burger Month, a time to celebrate your favorite patty and bun combo. That could mean beef, turkey, plant-based, or whatever other ingredient the food industry is pushing next (just, please, leave cauliflower out of this). When food “holidays” like National Burger Month roll around, we expect to see free food deals. That was the case on National Slider Day, May 15, 2023. (National Hamburger Day was May 28.) Every year, White Castle sliders get their moment in the spotlight, with the chain offering a free slider to customers for White Castle free slider day.
Fortunately, this year was no different. White Castle offered a free cheese slider on May 15, no purchase necessary. Plus, there plenty of other savings for National Slider Day, that we expect will return for 2024.
