Get ready to sink your teeth into one of America’s most iconic creations—because September 18th is National Cheeseburger Day! From backyard grills to gourmet gastropubs, this juicy classic has earned its place as the king of comfort food. Whether you like it piled high with toppings, smothered in melty cheese, or kept simple and traditional, today is the perfect excuse to indulge.

The cheeseburger’s exact origins are debated, but most food historians credit Lionel Sternberger, a 16-year-old fry cook in Pasadena, California, who supposedly topped a sizzling hamburger with a slice of cheese back in the 1920s. That simple addition transformed a good sandwich into a legendary one. Since then, cheeseburgers have grown into a cultural staple, with countless variations around the world.
Restaurants across the country often celebrate with special deals, making it the ultimate time to try something new—or stick with your tried-and-true favorite. So gather your friends, bring your appetite, and honor the timeless marriage of beef and cheese. After all, nothing brings people together quite like a perfectly cooked cheeseburger.

Lionel Sternberger was 16 years old in 1926, flipping burgers inside his dad’s sandwich shop, the “Rite Spot,” in Pasadena, California. But, here’s where things get interesting. Consistent with most how-it-got-started stories, there are two versions. In one, Lionel, out of curiosity, added a piece of American cheese onto a hamburger frying on the griddle. In version two, a homeless passerby saw Lionel working those burgers and suggested adding cheese. Either way, the rest is mouth-watering, delicious history. Prepare to enjoy an American food icon — a cheeseburger oozing warm cheesy deliciousness on top of a moist, juicy patty.
