The Mushroom Swiss Burger at Whataburger is a relatively new menu item that comes with two all-beef patties, two slices of melted cheese, and two layers of grilled mushrooms topped with creamy Au Jus Sauce and served on a soft warm bun.

Whataburger’s Mushroom Swiss Burger has a whopping 1080 calories and 69 grams of total fat. For comparison, Burger King’s Big King XL has 980 calories and just 27 grams of fat. And Jack in the Box’s Double Jack, which is about the same weight as the Mushroom Swiss, only has 830 calories.

Now, 980 calories is a lot, granted, and so is 830. But anything over 1000 calories is too much. And we haven’t even added the fries yet. Speaking about French fries, the Mushroom Swiss Whatameal is 1900 calories, but you can order it with lower calorie sides for a grand total of 1120 calories.

If you’re trying to lower your calorie intake and you also want to enjoy a Mushroom Swiss, then go with the Mushroom Swiss Jr. which only contains 650 calories and 40 grams of fat. That’s still a lot, but it’s better than consuming over a thousand calories in a single sitting.

One thing is for certain, this burger is delicious. So if you don’t care about the extra calories, go for it.
