National Cheeseburger Day 2025 was celebrated on Thursday, September 18, 2025, giving burger lovers across the United States another reason to enjoy one of America’s most recognizable comfort foods. From classic beef patties topped with melted American cheese to gourmet burgers loaded with specialty toppings, the day has become a popular occasion for restaurants, food brands and cheeseburger fans.
The celebration is particularly interesting because National Cheeseburger Day is not simply about eating a burger. It also provides an opportunity to explore the history of the cheeseburger, the competing stories surrounding its invention, the reason September 18 is associated with the celebration, and the restaurant promotions that made the 2025 event especially popular.
In 2025, major chains including McDonald’s, Burger King, Dairy Queen, White Castle, Five Guys, Whataburger, Carl’s Jr., Buffalo Wild Wings and others promoted special cheeseburger offers. Some were available only through loyalty programs or mobile apps, while others applied to participating restaurants for a limited time.
What Is National Cheeseburger Day?
National Cheeseburger Day is an annual food celebration dedicated to the cheeseburger, one of the most popular variations of the classic hamburger. In the United States, the occasion is observed on September 18 each year. National Day Calendar lists September 18 as the date and encourages people to celebrate by making, ordering or sharing a cheeseburger.
Unlike an official federal holiday, National Cheeseburger Day is a food themed observance rather than a government recognized public holiday. It does not generally mean a day off work or school. Instead, it gives restaurants an opportunity to promote cheeseburger specials while giving consumers a fun reason to try their favorite burger or discover a new one.
The basic idea is simple: take a hamburger patty, add cheese and enjoy the combination. However, modern cheeseburgers have developed into an enormous category of food. They can include cheddar, American, Swiss, pepper jack, blue cheese or other varieties, along with toppings ranging from lettuce and tomato to bacon, onions, pickles, sauces and specialty ingredients.
For people searching for national cheeseburger day 2025, the key date was September 18, 2025. Because that date has already passed, current searches are generally looking for information about the 2025 celebration, its deals, history and notable promotions rather than upcoming offers.
When Was National Cheeseburger Day 2025?
National Cheeseburger Day 2025 took place on Thursday, September 18, 2025. The date fell in the middle of September, continuing the annual tradition of celebrating the cheeseburger on September 18.
For consumers, September 18 was the main day to look for limited time restaurant promotions. Some offers lasted longer than the actual holiday. For example, Dairy Queen’s 2025 promotion extended across several days, while White Castle’s offer ran from September 18 through September 21.
The fact that many promotions were tied to mobile applications or rewards programs was also significant. Customers who wanted the best National Cheeseburger Day deals often needed to check a restaurant’s app, join its loyalty program or use a promotional code before placing an order.
Because restaurant promotions can vary by location, availability and participation, advertised offers should always be treated as limited time promotions rather than permanent menu prices. This was particularly important for 2025 deals, many of which were restricted to participating U.S. locations.
Why Is National Cheeseburger Day Celebrated?
National Cheeseburger Day celebrates the combination of two familiar American foods: the hamburger and cheese. Adding melted cheese to a burger may seem like a small culinary change, but it transformed the sandwich into one of the world’s most recognizable fast food and casual dining options.
The cheeseburger also represents the evolution of American roadside and restaurant food. Over the decades, a simple beef patty between a bun became a customizable meal that could be adapted to different tastes, budgets and regional food traditions.
For restaurants, the occasion has an additional commercial appeal. A food holiday creates a natural reason to introduce discounts, promote loyalty programs and encourage customers to visit restaurants or order through mobile apps. The 2025 promotions demonstrated how effectively food holidays can connect consumer interest with restaurant marketing.
There is also a social element. Cheeseburgers are easy to share at cookouts, family gatherings, casual dinners and restaurant outings. National Cheeseburger Day therefore works both as a marketing event and as an informal celebration of a familiar comfort food.
National Cheeseburger Day History
The history of National Cheeseburger Day itself is less certain than the history of the cheeseburger. National Day Calendar says it continues to research the origins of the food holiday, which means there is not a universally accepted historical explanation for why September 18 became the designated date.
Some secondary sources claim that the first National Cheeseburger Day was observed in 2000, but that claim should be treated cautiously because the origins of many national food days are difficult to document and are not necessarily tied to a formal government proclamation. The important point for consumers is that September 18 is now widely recognized as the annual date.
The cheeseburger itself has a much more interesting history. Several people and restaurants have claimed credit for creating it, and there is no single universally accepted inventor. Pasadena, California, is particularly associated with Lionel Sternberger, while other claims point to restaurants in Louisville and other parts of the United States.
This uncertainty does not make the cheeseburger’s history less interesting. Instead, it shows how quickly the idea of putting cheese on a hamburger could have developed in different places during the early decades of American burger culture.
Who Invented the Cheeseburger?
One of the most famous cheeseburger origin stories involves Lionel Sternberger, a young cook who worked at his father’s Rite Spot restaurant in Pasadena, California. According to the commonly repeated story, Sternberger was only 16 when cheese was added to a hamburger during the 1920s. National Today describes competing versions of the story, including one in which Sternberger experimented with adding cheese and another in which a passerby suggested the idea.
Pasadena has embraced this connection to cheeseburger history, but it is not the only place to claim the invention. Kaelin’s Restaurant in Louisville, Kentucky, has claimed that it created the cheeseburger in the 1930s. National Day Calendar also notes that the Humpty Dumpty Drive In in Denver received a trademark for the word “cheeseburger” in 1935.
These competing claims are why it is safer to say that Lionel Sternberger is one of the most frequently credited early cheeseburger pioneers, rather than stating that he is unquestionably the sole inventor.
The broader history suggests that adding cheese to hamburgers was an idea whose popularity grew during the 1920s and 1930s. As hamburger restaurants and drive ins expanded, the cheeseburger became a natural variation of an already popular meal.
How Did the Cheeseburger Become Popular?
The cheeseburger benefited from the growth of diners, drive ins, roadside restaurants and fast food culture in the United States. A hamburger was already convenient, inexpensive and easy to eat, while cheese added richness and flavor without fundamentally changing the structure of the meal.
As restaurant chains expanded, standardized burger menus helped make the cheeseburger familiar to consumers across different states. The combination of bun, beef patty, cheese and toppings became a foundation that restaurants could modify in countless ways.
The growth of fast food further strengthened the cheeseburger’s cultural importance. Major chains developed recognizable versions that could be ordered quickly and consistently, while independent restaurants created their own signature interpretations.
Today, cheeseburgers occupy almost every level of the restaurant market. A customer can buy an inexpensive fast food cheeseburger, order a casual dining burger with fries, visit a gourmet burger restaurant or make a customized version at home.
What Makes a Cheeseburger Different From a Hamburger?
The basic difference is straightforward: a cheeseburger is a hamburger served with cheese. A hamburger can contain a beef patty and various toppings without cheese, while a cheeseburger includes at least one type of cheese as part of the finished sandwich.
The cheese itself can dramatically change the character of the burger. American cheese is popular because it melts smoothly, while cheddar offers a stronger flavor. Swiss cheese can create a milder, nutty profile, and pepper jack adds heat and creaminess.
Beyond cheese, the toppings can transform the burger into entirely different styles. Pickles provide acidity and crunch, onions add sweetness or sharpness, lettuce contributes freshness, and sauces bring additional flavor.
That flexibility is one reason cheeseburgers remain so popular. There is no single required combination beyond the basic burger and cheese concept, allowing restaurants and home cooks to develop their own versions.
National Cheeseburger Day 2025 Deals and Promotions
National Cheeseburger Day 2025 generated substantial interest because several major restaurant brands announced special offers. Many were designed to attract customers through mobile applications, loyalty programs and digital ordering.
McDonald’s was among the most notable examples. On September 18, 2025, customers could get a Double Cheeseburger for 50 cents through the McDonald’s app, according to Time Out’s roundup of the day’s promotions.
Burger King also promoted a major offer for Royal Perks members, with a free cheeseburger available with a qualifying purchase at participating U.S. locations. Different sources reported variations in the exact burger and offer wording, so customers were advised to check the chain’s current app terms.
Dairy Queen offered Rewards members a free Double Original Cheeseburger Stackburger with an app or online order of at least $1. Its promotion covered multiple days around September 18, making it one of the longer National Cheeseburger Day promotions in 2025.
White Castle also participated with a buy one get one free Cheese Slider promotion using the code SAYCHEESE at participating locations from September 18 through September 21.
McDonald’s National Cheeseburger Day 2025 Offer
McDonald’s generated considerable attention with its 50 cent Double Cheeseburger promotion. The offer was available through the McDonald’s app on September 18, making it one of the most notable low price cheeseburger promotions of the day.
The promotion illustrated how restaurant chains increasingly use national food days to drive app engagement. Instead of simply offering a discount to everyone who walked into a restaurant, McDonald’s connected the deal to its digital ordering platform.
For consumers, this meant that checking the app before visiting was important. Promotional prices can depend on account eligibility, location and availability, so the exact offer shown in the customer’s app was the most relevant source at the time.
Burger King National Cheeseburger Day 2025 Offer
Burger King joined the 2025 celebration with an offer aimed at Royal Perks members. Reports described a free cheeseburger or Bacon Cheeseburger with a qualifying purchase, depending on the promotion and source.
The promotion demonstrated another major trend in restaurant marketing: loyalty programs have become central to food holiday discounts. Rather than relying only on traditional coupons, chains can now distribute offers directly to customers through apps and rewards accounts.
Anyone researching the 2025 promotion after the event should remember that these were limited time offers. They should not be interpreted as current Burger King menu prices or ongoing promotions.
Five Guys National Cheeseburger Day 2025 Promotion
Five Guys also celebrated National Cheeseburger Day in 2025. The company announced its first National Cheeseburger Day promotion, offering participating customers either a buy one get one free cheeseburger promotion or 50% off a cheeseburger with a qualifying purchase.
According to Five Guys, the promotion was valid on September 18, 2025, and was available through digital ordering for participating U.S. locations and selected Canadian locations. The company said promotional codes were distributed through its email program and social media channels.
Five Guys’ participation was notable because the chain is known for customizable burgers and a broad selection of toppings. Its 2025 campaign therefore fit naturally with the theme of celebrating cheeseburgers while encouraging customers to order digitally.
Dairy Queen National Cheeseburger Day 2025 Promotion
Dairy Queen extended its 2025 cheeseburger celebration beyond a single day. Rewards members could receive a free Double Original Cheeseburger Stackburger with a qualifying $1 or more app or online order during the promotional period.
The promotion was particularly appealing to customers who already used the DQ Rewards system. Instead of requiring a standalone cheeseburger purchase, the offer connected the free burger to a minimum qualifying order.
This type of promotion is increasingly common during food holidays because it encourages customers to use a restaurant’s digital ecosystem while also creating a strong perception of value.
Other National Cheeseburger Day 2025 Deals
Several other chains offered promotions around September 18. Whataburger, for example, offered a free fry or onion ring with the purchase of a number 5 Bacon & Cheese Whataburger, while Carl’s Jr. offered rewards members a half price Western Bacon Cheeseburger with the purchase of a large fountain drink.
Buffalo Wild Wings offered a buy one get one burger promotion to rewards members, while Smashburger offered selected burgers for a reduced price. White Castle’s BOGO Cheese Slider offer also extended beyond September 18.
Jollibee also promoted National Cheeseburger Day with a buy one get one Angus Cheeseburger reward for new Jollibee Rewards members who joined between September 18 and September 21. The company’s official promotion described the offer as applying to its Angus Cheeseburger.
Because restaurant promotions can change by market, the best practice for future food holidays is to verify the offer in the restaurant’s official app or website before ordering.
How to Celebrate National Cheeseburger Day
The easiest way to celebrate National Cheeseburger Day is to enjoy a cheeseburger you genuinely like. That could mean visiting a favorite restaurant, trying a new burger chain or making one at home.
A homemade cheeseburger can also turn the occasion into a fun cooking project. Start with a good quality beef patty, choose a cheese that melts well and add toppings based on your preferred flavor profile. Toasting the bun can provide additional texture and prevent it from becoming soggy.
Another option is to create a cheeseburger tasting night. Prepare several small burgers with different cheeses and toppings, then compare them with friends or family. American cheese, cheddar, Swiss and pepper jack can produce noticeably different results.
For people who prefer not to eat beef, the cheeseburger concept can also be adapted with chicken, turkey, vegetarian patties or plant based alternatives. The basic celebration is about enjoying the combination of a burger style sandwich and cheese rather than following one strict recipe.
Best Cheeseburger Topping Ideas
Classic toppings remain popular because they balance the richness of beef and cheese. Lettuce, tomato, onions and pickles add freshness, crunch and acidity, while ketchup and mustard provide familiar flavors.
Bacon is another popular addition, particularly when paired with cheddar or American cheese. Caramelized onions can add sweetness, while jalapeños or spicy sauces can give the burger a stronger kick.
For a more gourmet approach, consider toppings such as sautéed mushrooms, roasted peppers, avocado, fried onions or specialty sauces. The important thing is balance. Too many rich ingredients can overwhelm the beef and cheese.
A good cheeseburger does not necessarily need a long list of toppings. Sometimes a toasted bun, properly seasoned patty, melted cheese, pickles and a simple sauce provide everything needed for a satisfying meal.
Why Is National Cheeseburger Day Trending?
National Cheeseburger Day becomes particularly visible online because it combines a familiar food with limited time promotions. Restaurants have an incentive to promote discounts, while consumers have an incentive to search for them.
Social media also plays a role. Customers can share burger photos, restaurant recommendations, deals and homemade recipes. Food related content is naturally visual, making cheeseburgers particularly suitable for platforms built around images and short videos.
Search interest also increases because consumers often look for specific terms such as “National Cheeseburger Day deals,” “free cheeseburger,” “cheeseburger deals near me” and “National Cheeseburger Day 2025.” These searches combine the informational nature of a food holiday with a strong transactional element.
The 2025 event demonstrated this pattern clearly. Major media outlets published deal roundups, while restaurant chains promoted their own offers through websites, apps, email lists and social media.
National Cheeseburger Day vs National Hamburger Day
National Cheeseburger Day and National Hamburger Day are separate food observances, although the two naturally overlap. National Cheeseburger Day focuses specifically on burgers topped with cheese, while National Hamburger Day is broader and celebrates hamburgers generally.
This distinction matters for people searching for restaurant promotions. A chain may release different deals for different food holidays, and the dates do not necessarily match.
Cheeseburger Day is particularly appealing to consumers because cheese provides an obvious point of differentiation. Restaurants can promote classic cheeseburgers, bacon cheeseburgers, specialty burgers and limited time cheese based variations.
For content and search purposes, terms such as “National Cheeseburger Day date,” “National Cheeseburger Day deals” and “when is National Cheeseburger Day” are therefore more precise than generic hamburger related searches.
Are National Cheeseburger Day Deals Available Every Year?
Many restaurants participate in National Cheeseburger Day, but there is no guarantee that a particular chain will offer a discount every year. Promotions are determined independently by individual companies and can change according to marketing strategy.
Some restaurants repeat familiar types of offers, such as free burgers with qualifying purchases, discounted cheeseburgers, BOGO promotions or app only prices. Others may skip the occasion entirely or introduce a completely different promotion.
The 2025 offers show why customers should check official restaurant apps and websites rather than relying on old deal articles. A promotion from 2025 may no longer be valid even if an online page remains accessible.
When researching a future National Cheeseburger Day, always check the promotion date, participating locations, eligibility requirements and expiration time before making a special trip.
Are National Cheeseburger Day Promotions Available Outside the United States?
National Cheeseburger Day is primarily associated with the United States, although international restaurant brands may choose to participate in other countries. The availability of a promotion therefore depends on the local market.
Even when an international chain advertises a National Cheeseburger Day promotion, the offer may have different terms in different countries. Menu items, prices, loyalty programs and participating restaurants can vary significantly.
For this reason, consumers outside the United States should check their country’s official restaurant website or mobile app rather than assuming that a U.S. promotion applies locally.
Five Guys, for example, stated that its 2025 National Cheeseburger Day promotion was available at participating U.S. locations and selected Canadian locations, illustrating how promotional availability can differ by market.
How to Find the Best Cheeseburger Deals
The easiest way to find National Cheeseburger Day deals is to check restaurant apps and loyalty programs before the celebration begins. Many of the strongest 2025 offers were restricted to app users or rewards members.
It is also useful to check the official social media accounts of favorite restaurants. Some promotions are announced shortly before the event, while others are distributed through email newsletters or loyalty accounts.
Deal roundups from reputable food and lifestyle publications can also help consumers compare multiple restaurants. However, third party lists should be treated as a starting point because participating locations and terms can change.
Finally, check the fine print. A “free burger” may require a purchase, a discount may be app only, and a promotion may be limited to one item per customer. Understanding the conditions can prevent surprises at checkout.
What Should You Know Before Using a Cheeseburger Deal?
Before using a promotional offer, verify the expiration date and whether the restaurant location participates. National food day deals frequently have strict time limits.
Next, check whether the offer requires a rewards account, mobile app, promotional code or qualifying purchase. In 2025, several major cheeseburger promotions used exactly these restrictions.
You should also confirm whether the promotion applies to delivery, pickup, dine in or only one ordering method. Some offers are available through a restaurant’s own digital channels but not through third party delivery platforms.
Taking a few seconds to check these details can make the difference between successfully receiving a discount and discovering that the promotion does not apply to your order.
Latest Update on National Cheeseburger Day
The latest historical update for the keyword national cheeseburger day 2025 is that the celebration took place on September 18, 2025, with widespread participation from restaurant chains and food brands.

Among the most widely reported promotions were McDonald’s 50 cent Double Cheeseburger, Burger King’s rewards promotion, Dairy Queen’s free Double Original Cheeseburger Stackburger offer, White Castle’s BOGO Cheese Slider deal and Five Guys’ first dedicated National Cheeseburger Day promotion.
For future celebrations, September 18 remains the date to watch. Restaurant deals may differ from year to year, so consumers should rely on current official promotions rather than assuming that 2025 offers will return unchanged.
