Mushroom Swiss Burger Returns to Whataburger

After a three-year hiatus, the Mushroom Swiss Burger returns to Whataburger for a limited time starting April 1, 2025.

Whataburger's Mushroom Swiss Burger features two grilled beef patties, melted Swiss cheese, creamy au jus sauce, and two layers of grilled mushrooms, served on a toasted bun. For those with a lighter appetite, a Jr. version is also available.

Starting tomorrow, you'll be able to find it at participating Whataburger locations chain-wide through June 2, 2025.
