National Cheeseburger Day

Saturday, September 18, 2027 Every year on September 18

A juicy burger patty topped with melted cheese is a match made in heaven. National Cheeseburger Day, on September 18, celebrates the cheeseburger, one of America's most iconic foods. From classic American cheese on a soft bun to gourmet versions with blue cheese, pepper jack or Swiss, there's a cheeseburger for every taste. It's a perfect day to fire up the grill one more time before fall.

History of National Cheeseburger Day

The hamburger became popular in the United States in the early 1900s, but who first added cheese is debated. One popular story credits Lionel Sternberger, a teenager working at his father's sandwich shop, The Rite Spot, in Pasadena, California, in the mid-1920s. He reportedly dropped a slice of American cheese on a burger.

Other claims include Kaelin's Restaurant in Louisville, Kentucky, which says it served a cheeseburger in 1934. In 1935, Louis Ballast of the Humpty Dumpty Drive-In in Denver applied for a trademark on the name 'cheeseburger'.

After World War II, cheeseburgers became a fast-food staple. Regional variations include Minneapolis' 'Juicy Lucy', with cheese stuffed inside the patty, and New Mexico's green chile cheeseburger. Who created National Cheeseburger Day is not documented.

Why National Cheeseburger Day Matters

Its competing origin stories show how food history is often shaped by local pride and legend.

Cheeseburgers are also endlessly customizable, letting cooks experiment with cheeses, toppings and buns. Regional variations are a fun way to explore American food traditions.

The cheeseburger is also a great example of how a small change can create a classic. Adding a single slice of cheese transformed the hamburger into one of the most-ordered foods in America. Today, cooks continue to experiment with cheeses, sauces and buns, keeping this simple idea fresh.
