Diners Say You Need To Try This Culver's Burger At Least Once

Culver's is the Midwestern chain to visit if you love buttery burgers and high-quality custard. Its menu is small but mighty, featuring classics like cheeseburgers with and without toppings, plus even some patty melts. It also has one fairly unique fast food burger fans are obsessed with: the mushroom and Swiss ButterBurger.

The sandwich starts off simple, with a choice of one, two, or three patties between the chain's signature buttered Kaiser buns (toasted, of course). Then things get interesting: Wisconsin-made Swiss cheese and buttery, garlicky, well-seasoned white button mushrooms sit atop the beef.

It's not a burger you see on many fast food burger chain menus, and fans — pun totally intended — eat up this unique item. On Reddit, people's thoughts on the burger are overwhelmingly positive, with one writing, "The mushroom Swiss is elite." Another Redditor said, "One time they got my order wrong and gave me the mushroom and Swiss instead of the Swiss melt. I wasn't even mad [because] I ended up loving the burger." A Yelp reviewer wrote, "My go-to is the mushroom and Swiss burger. It's perfectly buttery, savory, and just hits the spot every time."

Whether you're a longtime fan of the mushroom and Swiss or you're setting out to try it for the first time, customers have recommendations for how to make it even better. One Redditor recommended adding bacon, onions, and extra butter; multiple commenters agreed about the caramelized onions. Others suggested mayo or pickles. Some questioned the pickles, but another Redditor noted, "I never thought about putting pickles on a mushroom and Swiss burger, but that little kick of acid might actually be great!"

Unfortunately, Culver's isn't everywhere, leaving many unable to try this beloved burger at the chain. If that's you, don't fret. Culver's is fairly explicit with what's in the sandwich, so fans can make copycats, and no road trip is required to get a taste. First off, the butter in Culver's ButterBurgers doesn't go where you might think — pick up some hamburger buns, toast them, and butter the insides.

Then, as one TikTok user recommended, make super thin smash burger patties, and mix mushrooms with Culver's listed ingredients — butter, garlic, salt, pepper, and parsley — and a half cup of milk with one tablespoon of flour. Cook the mushroom mix and spoon it over your preferred number of patties with some melted Swiss cheese, and you've got yourself a copycat Culver's mushroom and Swiss ButterBurger.
