The exact origins of cheeseburger sliders are somewhat elusive, but they are believed to have evolved from the traditional hamburger. Sliders are often associated with White Castle, the renowned American fast-food chain that popularized the concept of small, square-shaped burgers. White Castle introduced its signature sliders in the 1920s, offering affordable and convenient meals during a time of economic hardship. These sliders became a cultural icon and paved the way for the widespread popularity of miniature burgers.
