The Most Outrageously Huge Fast-Food Burgers of All Time

If you thought the Big Mac was big, wait until you see these beefy behemoths.

If you're going to eat a burger, go big or go home. At least that's the philosophy that many fast-food lovers embrace. Of course, the biggest burger you can possibly find doesn't exist on a typical menu, but rather through the option available at many restaurant chains to concoct custom burgers with any number of patties and toppings. This DIY route allows ambitious fast-food enthusiasts to create Frankensteinian burger towers with belt-breaking calorie counts. If you're wondering how out-of-hand that gets, take a look at In-n-Out's secret menu monstrosities, the 4×4 burger, and the mythical 100×100 burger.

These burgers are undoubtedly impressive, and their sizes and calorie counts are the stuff of legend and lore. If you're wondering where to find the biggest burgers, feast your eyes on these beefy behemoths from your favorite fast-food chains. Then, go ahead and take a trip down memory lane with the 15 Classic American Desserts That Deserve a Comeback.

1,686 calories, 96.5 g fat (33.5 g saturated fat, 6.5 g trans fat), 2,179 mg sodium, 69 g carbs (4 g fiber, 12 g sugar), 129.5 g protein

Typically "challenge" burgers like the XXXL are restricted to secret menus or one-off food competition events, but this 1.5-pound behemoth—comprised of 3 towering 1/2 pound burger patties and toppings—can be ordered straight from the menu. It would take quite a few people to finish this bad boy, that's for sure!

1,080 calories, 63 g fat (21 g saturated fat, 3 g trans fat), 1,720 mg sodium, 62 g carbs (4 g fiber, 12 g sugar), 65 g protein

While other massive burgers proudly tout their weight as their defining feature, the Triple Meat flies under the radar and blends in with its third- and half-pound competitors. At 1,080 calories, the total weight listed on its nutritional information is 484 grams, or just over a pound, and it's not the lettuce that's tipping the scales.


SuperSONIC Bacon Double Cheeseburger

1,030 calories, 58 g fat (23 g saturated fat, 2 g trans fat), 1,880 mg sodium, 54 g carbs (3 g fiber, 12 g sugar), 58 g protein

Its neat and tidy presentation might give a customer the impression that this burger from SuperSONIC is somehow less indulgent than its competitors. But don't be fooled—each of its patties weighs a substantial quarter pound, and the total calorie count after including the bacon, cheese, and mayo is an impressive 1,030.


Fuddruckers 1lb Original Burger

1,390 calories, 26 g saturated fat, 1,190 mg sodium, 72 g carbs

The most gluttonous thing on the Fuddruckers menu also sounds the most innocent: the Original Burger. The trick here is selecting the diet-busting one-pound option. The concept at Fuddruckers is to dress your own burger at their produce bar, but given that a burger and a bun alone will run you 1,387 calories, this is far from the innocuous meal that its name suggests.

Wayback may be a lesser-known fast-food chain, but if you should happen to come across one of these, you're in luck.

It included nine beef patties and nine slices of American cheese with a whopping calorie count of 1,780. It's no longer on the menu, but we couldn't resist looking back at this monstrous burger that once was.
