By the late 19th century, the vast grasslands of the
Great Plains had been opened up for cattle ranching. This made it possible for many Americans to consume beef almost daily. The hamburger remains as one of the cheapest forms of beef in America. Adding cheese to hamburgers became popular in the 1920s. There are several competing claims as to who created the first cheeseburger. Lionel Sternberger is reputed to have introduced the cheeseburger in 1924 at the age of 16. He was working as a fry cook at his father's
Pasadena, California, sandwich shop, "The Rite Spot", and "experimentally dropped a slab of American cheese on a sizzling hamburger." An early example of the cheeseburger appearing on a menu is a 1928 menu for the Los Angeles restaurant O'Dell's, which listed a cheeseburger smothered with chili for 25 cents, or about 4.7 dollars in 2025 after inflation. Other restaurants also claim to have invented the cheeseburger. For example, Kaelin's Restaurant in
Louisville, Kentucky claims they invented the cheeseburger in 1934. One year later, a
trademark for the name "cheeseburger" was awarded to Louis Ballast of the Humpty Dumpty Drive-In in
Denver, Colorado. According to
Steak 'n Shake archives, the restaurant's founder, Gus Belt, applied for a trademark on the word in the 1930s. Dale Mulder, the owner of an
A&W Restaurants franchise in
Lansing, Michigan, has been credited with inventing the bacon cheeseburger in 1963, putting it on the menu after repeated requests from the same customer. This was highlighted in a 2014 ad campaign for the chain featuring Mulder, who had since become the president of the A&W chain. However, there are earlier examples of a restaurant selling bacon cheeseburgers, including a menu for a
Harrisburg, Pennsylvania restaurant from 1941. The
steamed cheeseburger, a variation almost exclusively served in central
Connecticut, is believed to have been invented at a restaurant called Jack's Lunch in Middletown, Connecticut, in the 1930s. The largest cheeseburger ever made weighed . It is said to have included " of bacon, of lettuce, of sliced onions, of pickles, and of cheese." This record was set in 2012 by Minnesota's Black Bear Casino, smashing the previous record of .
