What Makes Culver's ButterBurgers A Delicious Fan-Favorite

ButterBurgers are Culver's signature dish, triumphing as a core part of the restaurant's menu since the very start. Deriving its name from its buttered-up buns, ButterBurgers look like any other fast casual chain restaurant burger from the outside. Two smash patties are topped with slices of American cheese, pressed freshly into the grill at every location. The patties' home becomes the interior of a buttered, toasted bun, further housing a variety of toppings and condiments, different depending on the order.

It's a simple preparation method on the surface. But, since Culver's humble beginnings, ButterBurgers have stood out to customers as a favorite. Not just at Culver's either. Some have declared that there's nothing better. It's a serious claim, and one that can only be substantiated by looking into the burger itself. This includes taking a glance at its historical roots, where its ingredients are sourced, and how it all comes together to deliver a memorable meal that leaves customers raving.

ButterBurgers have been a Culver's staple since the chain's very first restaurant opened its doors. Operating out of Sauk City, Wisconsin, the debut Culver's was opened in 1984 by Craig and Lea Culver. The pair were aided by Craig's parents, George and Ruth Culver, who themselves were restaurant owners. Craig was inspired by his parents running an A&W in the 1960s, deciding to follow in their footsteps with a restaurant carrying their namesake. Upon its opening, the restaurant touted two signature items: frozen custard and ButterBurgers. Culver's originally used an ice cream scooper to measure just the right amount of burger meat for the ButterBurger before pressing it onto the restaurant's grill.

By 1990, Culver's had franchised in Wisconsin. The following decades saw its success bloom across the United States, with locations now in 27 states, most recently adding Virginia in early 2026. By 2024, it had grown into the seventh biggest limited-service burger chain in the U.S., making larger sales than In-N-Out Burger and Five Guys. While its growth over the decades can be attributed to plenty of factors, the most common is the ButterBurger. It's been a signature of the restaurant since it began, and is served at every one of its over 1,000 locations. Culver's family-focused history is but the groundwork for why its signature burger is so beloved.

The most important ingredient in a ButterBurger is, of course, the beef patties. Culver's sources its beef from trusted farmers, with some of the restaurant's closest partners having supplied beef for decades. While the business doesn't publicly state its partners, the restaurant is dedicated to ensuring all beef is fresh and never frozen when it's pressed down onto the grill. This commitment to freshness is a core part of the chain's mission to deliver high-quality food to customers at all of its locations across the country.

This approach helps Culver's stand out, especially because of how forward the restaurant is about the meat's freshness. It's not just a slogan to tout, though. Customers say it has a genuine impact on the taste of the beef. Some are quick to call ButterBurgers the best chain restaurant burgers ever made because of how fresh-grilled and seasoned the patties are. The novelty of the meat's preparation methods matches the cleanliness of the restaurant too. It's clear the freshness of the meat is a strong reason why customers adore the ButterBurger so much, keeping true to Culver's promises about the way it prepares its patties.

ButterBurger patties aren't just prepared fresh. The meat also consists of a unique combination of cuts, giving every patty the rich flavor it's known for. Culver's ButterBurger patties consist of three cuts. The first is sirloin, offering a rich, strong beefy flavor. The second, chuck, affords a richness that, fittingly, goes well with butter. Finally, plate adds a fattiness with similar flavors as the other two cuts. All three are ground together into fresh beef patties before getting pressed into the grill.

The combination of meats has remained an important aspect of Culver's ButterBurger preparation. The burger patties are all the more unique because of both the meat's freshness and the specific sirloin, chuck, and plate cuts. Without the restaurant's staple combination and unique approach, the ButterBurger wouldn't have the taste that's turned it into a generational favorite. Blending three cuts of beef together may be simple, but it's an important part of how Culver's signature burger is crafted.

Butter is vital in a ButterBurger. But before it makes it onto the toasted bun, it first needs to be created somewhere. Culver's prides itself on using real dairy products sourced from farmers the restaurant has built trustworthy partnerships with over the decades. This includes its butter and the slices of American cheese used on ButterBurgers and grilled cheese.

But the restaurant's dedication to dairy farmers goes far beyond the table. Culver's shows appreciation for its farmers and highlights their achievements through its Thank You Farmers Project. Formed in 2013, the project raises money for education in and the production of agriculture, alongside feeding those in need. Funding has a local, Wisconsin focus. According to the website, over $8 million has been raised by Culver's and customers since the project began.

While it doesn't directly impact the taste of a ButterBurger, it's an important aspect of keeping its delicious butter and cheese around for generations to come. It also helps Culver's stand out as a company that deeply cares about its partner farms. The sources of its dairy are vital to the company's success and a crucial part of the ButterBurger's long-standing favor.

With a solid source for its dairy, it's not a surprise ButterBurgers have such a high level of quality for the sandwich's namesake. But it's the way butter is used that really drives home the dish's success. Culver's gently butters its burger buns, adding a slight creaminess to the interior of its rolls. ButterBurgers are traditionally served on Kaiser buns, lightly toasted to give the dish a complementary crunch. Buttered buns are a signature element of the burger, and one the chain restaurant pays rapt attention to when cooking every dish.

But don't just take Culver's word for it: Customers also attest to how important buttered buns are to the flavor of a ButterBurger. While a multitude of aspects go into making the sandwich, from the beef patties to the savory cheese, attendees say the burger wouldn't taste the same without a buttery, toasted bun. There's a passionate streak to customers who talk about the buns. It's primarily because the bun is toasted so lightly that its crunchy flakiness doesn't overwhelm the burger. The buttery bun makes the ButterBurger stand out from other fast casual restaurant offerings.

A blend of savory meats, people-first dairy sourcing, and delicious buns are some of the best qualities of a ButterBurger. But none of those attributes matter if the preparation method isn't pristine. Luckily, Culver's continues to put customers first with every patty. Every ButterBurger is made to order, meaning prep work doesn't start until after a customer places an order. Fresh, raw beef is pressed onto the grill, butter is spread across buns, and cheese is placed atop cooked patties — but only once the customer has made their order.

It's a very simple approach to burger preparation that does wonders for the freshness factor. There's a dedicated mission to ensure ButterBurgers are delicious that starts with a made-to-order approach. Customers say it's what makes Culver's unique in contrast to other fast food or fast casual locations. The freshness is apparent in every bite. It's all thanks to a preparation approach that puts quality first.

Culver's doesn't just serve up one version of the ButterBurger. Instead, Culver's carries multiple types of beef ButterBurgers that guarantee a variety for its customers to choose from. There's the classic ButterBurger, which contains pickles, onion, ketchup, and mustard, as well as the ButterBurger Cheese, which adds two slices of American cheese to the mix. The Culver's Deluxe substitutes mayo for the prior condiments, while also adding lettuce and tomato, while the Mushroom & Swiss changes the makeup entirely: two patties, two slices of Swiss cheese, and a scoop of sautéed mushrooms. There's also the Melt sandwiches, which stuff patties, cheese, and grilled onions between grilled slices of bread.

The menu variety means customers have plenty of choices, all of which are still freshly prepped and made with high-quality ingredients. It's worked wonders for the restaurant's praise. A number of customers single out the Mushroom & Swiss as the best alternative on the menu, praising it for a unique deliciousness in contrast to other ButterBurgers. But even a classic substitute like the Culver's Deluxe is considered deliciously tender, while the Sourdough Melt produces a familiar yet more sandwich-oriented experience. By producing many different types of ButterBurgers, Culver's is able to provide a wide array of customers the same high level of quality no matter the toppings.

A ButterBurger meal isn't whole without a delectable side and sweet-tasting drink to round it out. That's where Culver's Value Baskets come into play. These meal deals apply to every entree on Culver's menu, with the ButterBurgers being a core highlight. The meal consists of a burger, crinkle cut fries, and a regular drink. However, one unwritten rule of Culver's is to always upgrade one's sides and drinks to try out some of the restaurant's other classic menu items.

For sides, this includes fried pickles, onion rings, and highly-praised Cheese Curds, the latter's dairy sourced from Wisconsin farms. Customers can even substitute classic hand food for Clam Chowder or a variety of soups, from Chicken Noodle to Stuffed Green Pepper. Drinks, on the other hand, include a number of sugary-sweet options, like shakes or the restaurant's custard-infused root beer float.

The Value Basket puts a metaphorical bow on the ButterBurger as a meal. The variety of side and drink options ensures a filling serving that rounds out the customer experience. Many restaurant-goers are happy about the sides and drinks being procured. There's significant praise for the taste of Cheese Curds, while the root beer float is exceptional thanks to its use of custard. Both are just two additions to a ButterBurger meal that can elevate the sandwich. By offering customers the choice to turn the ButterBurger experience into a full-fledged lunch or dinner, Culver's bolsters the burger without directly changing the main course.

The high quality of Culver's ButterBurgers is also bolstered by how well the restaurant chain treats customers and the businesses it partners with. Everyone should know Culver's has a people-first approach to its business model. While the previously mentioned Thank You Farmers Project is one of its most generous for the agriculturalists it works with, it's not the only organization under the company's banner. The chain also offers money via sponsoring and donating to various organizations, including schools. There's also the Culver's Foundation, which includes assistance and scholarship programs for its workers. For Culver's, people are a priority — and it only makes its ButterBurgers all the better.

These programs have been in place for decades, but continue to be successful in the franchise's modern era. Since former marketing VP Julie Fussner was promoted to CEO in 2025, the restaurant has maintained a consistent, positive attitude toward being helpful in the communities it's part of. While this isn't a direct influence on the taste of the ButterBurger, Culver's generosity makes eating there feel even more preferable. Patrons can rest easy knowing the money spent on ButterBurgers is going to a good cause. And with a delicious dish as the exchange, it only furthers how dedicated Culver's is to its customer base.
