About National Double Cheeseburger Day
National Double Cheeseburger Day is celebrated every year on 15 September, and in 2026 it falls on Tuesday, 15 September. The day honours one of America’s most indulgent fast-food creations: two beef patties, two slices of melting cheese and all the trimmings stacked into a single burger. It is a light-hearted excuse to fire up the grill, visit a favourite burger joint or simply enjoy a classic comfort food.
How to Celebrate National Double Cheeseburger Day
This is a day made for eating, so the best way to mark it is to get stuck in. Here are plenty of ideas to make the most of it.
- Build your own at home – Grill two beef patties, melt a slice of cheese over each, and stack them with your favourite toppings for the ultimate homemade double.
- Visit a classic burger joint – Head to a local diner or chain known for its doubles, such as the famous Double-Double that helped popularise the style.
- Throw a backyard cook-out – Invite friends and family round, set up the barbecue and let everyone assemble their own double cheeseburger.
- Experiment with cheese – Swap the usual American cheese for cheddar, Swiss, blue or pepper jack to discover a new favourite combination.
- Go gourmet – Add caramelised onions, smoked bacon, a fried egg or a special sauce to elevate your double into a restaurant-worthy creation.
- Try a plant-based double – Use two meat-free patties and dairy-free cheese so vegetarians and vegans can join the celebration.
- Host a taste test – Order doubles from a few different places and rank them on flavour, value and that all-important cheese pull.
- Share the moment online – Photograph your creation and post it with the day’s hashtags to inspire fellow burger lovers.
What is National Double Cheeseburger Day?
National Double Cheeseburger Day is one of the many food-focused observances on the American calendar that celebrate beloved dishes. It is dedicated specifically to the double cheeseburger, a hearty variation on the classic cheeseburger built with two patties and two layers of cheese. The day is informal and unofficial, with no single organising body, and is embraced by burger fans, restaurants and home cooks alike as a reason to indulge.
When is National Double Cheeseburger Day?
National Double Cheeseburger Day takes place on 15 September each year, a fixed date that does not change. In 2026 it lands on a Tuesday, making it a perfect midweek treat. It sits within a busy September of food celebrations in the United States.
The History of National Double Cheeseburger Day
The precise origin of National Double Cheeseburger Day is unknown. Like many modern food holidays, it appears to have emerged in recent years as part of the wider trend of dedicating calendar days to iconic dishes, and no founder or sponsoring organisation has been definitively identified. What is far better documented is the history of the food itself.
The cheeseburger is widely credited to Lionel Sternberger, who is said to have added a slice of cheese to a beef patty in Pasadena, California, in 1926. The double version is harder to pin down. Bob’s Big Boy often gets the credit for an early double, beginning in 1937 with a burger that featured two patties separated by an extra slice of bun, though that differs from the traditional double cheeseburger we know today.
The modern double truly entered the spotlight thanks to In-N-Out Burger, which opened in 1948 and went on to popularise the format with its now-legendary Double-Double. From there the double cheeseburger became a fixture of American fast-food menus, and its enduring popularity is exactly what National Double Cheeseburger Day celebrates. If you enjoy this kind of food fun, you might also like National Hamburger Day, which honours the burger in all its forms.
