4 Restaurant Chains With the Best Butter Burgers, According to Diners

Culver’s, Jack in the Box, Steak ‘n Shake, and Smashburger are bringing a Wisconsin tradition to the national stage, offering butter burgers that lean on a rich, regional preparation method of melting butter directly into the toasted bun or onto the patty.

The Wisconsin Blueprint

The butter burger is a Midwest specialty defined by its rich flavor profile. While the technique originates in Wisconsin, several nationwide chains have integrated the method into their menus to appeal to broader markets, according to reports from Eat This Not That.

Culver’s and the ‘Elite’ Standard

Culver’s relies on fresh, never frozen beef for its ButterBurgers, which are made to order. The approach has resonated with diners; reviews cited by Eat This Not That describe the offering as perfect and underrated, with one customer labeling the burgers elite.

Smashed and Buttery Variations

Other chains have adapted the style to fit their own branding. Jack in the Box serves the Buttery Smashed Jack, which one diner claimed was the BEST hamburger I have ever tasted after multiple visits.

Smashburger takes a different route, achieving the flavor by toasting its buns in butter. One customer review cited by Eat This Not That described the result as delicious, served hot with American cheese, lettuce, and tomatoes.

Steak ‘n Shake’s Traditional Approach

Steak ‘n Shake offers two specific versions: the Butter Single and the Butter Double Steakburger. According to reports by Eat This Not That, one diner noted that this version aligns closely with the traditional Wisconsin style, treating butter as a topping in a manner similar to cheese.
