National Cheeseburger Day Deals and Freebies Announced

National Cheeseburger Day, observed annually on September 18, 2026, presents an opportunity to explore the origins of this iconic American dish and take advantage of numerous promotional offers from major fast-food chains. The cheeseburger's evolution is deeply intertwined with American culinary history, drawing inspiration from German Frikadellen, a dish of cooked chopped beef brought by immigrants in the late 1840s. The adoption of the bun, possibly influenced by the popularity of hot dogs in the late 1800s, further shaped the burger's form. Its presence at the 1904 World's Fair in St. Louis solidified its American legacy, coinciding with the increasing availability of meat grinders as common household items and the rise of industrial food production that fast-food chains would later leverage.

The addition of cheese to the hamburger is credited to Lionel Clark Sternberger, who was 16 years old and working at his father's restaurant, The Rite Spot, in Pasadena, California, in 1924. While the exact circumstances remain debated, with one account suggesting Sternberger burned a burger and used cheese to cover the mistake, and another attributing the innovation to a customer's request, the "Aristocratic Burger: the Original Hamburger with Cheese" was created. The term "cheeseburger" itself has competing claims for its first use. Charles Kaelin of Louisville, Kentucky, is noted for being the first to call the creation a cheeseburger in 1934. The following year, in 1935, Louis Ballast, the owner of Humpty Dumpty Drive-In in Denver, officially trademarked the name "cheeseburger."
