All the White Castle Deals You Can Score in March and April 2026

1921 was a big year. Einstein won a Nobel Prize for his work on general relativity. The first radio broadcast of a World Series game occurred. Chanel No. 5 debuted in Paris. Never mind all of that. In 1921, White Castle was born, making this year the chain’s 105th birthday. Appropriately, they’re celebrating by loading March and April with deals, discounts, promos, and excuses to grab some grub from the iconic purveyor of square sliders.

About White Castle

At 105 years young, White Castle is America’s first fast-food restaurant, predating McDonald’s by almost 20 years! They’re also the innovator of The Original Slider, and a family-owned business that now operates upwards of 300 restaurants in addition to stocking freezers with their iconic product, running Slider Provider meat plants, and feeding Harold and Kumar.

The deals

The deals they’re offering fall in line with warm weather — Jamie Richardson, chief marketing officer at White Castle, said, “As we head into spring, people are ready to shed their winter coats, soak up a little more sunshine and find simple, budget-friendly ways to gather and celebrate.” So, it’s great news if you’re totally over soup season, or haven’t meal-prepped all winter due to fully hibernating. In either case (or in the theoretically possible case that you’re a normal person and just want a slider), this is your chance! Some deals are available for the general public, others are more specific, but you can check out the offerings and plan accordingly.
