Fast-casual burger chain Culver's is turning up the flavor this fall with the return of its CurderBurger. This limited-time item will be front and center during this year's first annual Curdtoberfest, a monthlong celebration of all things cheese curds and Midwest tradition.

The CurderBurger, which began as an April Fools' joke in 2021 and quickly became a customer favorite, is back for its fifth year from Sept. 29 through Oct. 14, 2025, or while supplies last. This menu item features a Deluxe ButterBurger topped with a crown of golden-fried cheese made of a blend of yellow and white cheddar, breaded and fried.

Culver's is paying tribute to the cheese curd during the first ever Curdtoberfest. The new celebration is centered around cheese curds and Midwest tradition, coming to life across Culver's restaurant locations throughout October 2025. Customers can experience Curdtoberfest-themed decor at their local restaurant and enter an online sweepstakes to win free Wisconsin Cheese Curds for a year or other exclusive themed prizes.

"Curdtoberfest is our way of saying, 'Let's celebrate cheese curds!' by taking the spirit of Oktoberfest and adding our own Culver's twist on the tradition," said Emily Patterson, Culver's VP of marketing. "It's a month packed with cheesy goodness, Midwest pride and a lot of fun. Whether you're a CurderBurger loyalist or ready to try something new, we hope guests feel the magic every time they walk through our doors."
