McDonald's most diet-busting burger looks tame in comparison to the rest of this list, but it's no less a contender. Your quarter-pound patty will be topped with sharp white cheddar, smoked bacon, fried onion strings, sweet mustard, and a decadent-sounding smoky bacon-onion sauce.
A double-decker bun and a big dollop of tartar sauce crank up the calorie count on this otherwise simple half-pounder with cheese, lettuce, and pickles. Watch the sides at Frisch's: Your two choices could easily add 500 calories or more to this already hefty plate.
We reckon you'll need quite an appetite to plow through Red Robin's Southern Charm Burger. It's made with a half-pound of brown-sugar-glazed beef that's slathered in honey barbecue sauce, then topped with candied bacon, caramelized onions, mayo, and extra-sharp cheddar.
As its name suggests, BJ's Hickory Brisket and Bacon Burger features a heap of smoked brisket, barbecue sauce, and bacon atop the beef patty. But don't forget the mayo and two types of cheese, pepper jack and cheddar, to round out your indulgence.
At Hardee's, the only thing more extreme than the racy commercials is the burgers. Case in point: the Monster Thickburger, with two 1/3-pound patties, two slices of smoked bacon, cheese, and mayo. Go for the gold and make it a 1-pounder by adding another patty (and another 290 calories).
If you're "eatin' good in the neighborhood" tonight, beware of this Mexican-American mashup. The Quesadilla Burger is served up on a tortilla stuffed with beef, pepper jack cheese, smoked bacon, pico de gallo, lettuce, and Mexi-ranch sauce. Adding fries brings you to 1,770 calories — and perilously close to the 2,000-calorie daily recommendation for most people.
Clocking it at almost 1,500 calories, the Rodeo King is among the most over-the-top fast-food burgers. It's not exactly road food you can easily eat on the go, as you'll get more than a half-pound of beef, three half-strips of smoked bacon, onion rings, barbecue sauce, mayo, and cheese piled onto a sesame-seed bun.
Some evil genius at Buffalo Wild Wings decided that you can never have too much of a good thing, topping this massive cheeseburger with Wisconsin cheese curds in all of their fried glory. Rounding out your heart attack: bacon and a dollop of "cool heat sauce."
One look at the gut-busting Boss Beef Burger – "the burger all other burgers report to" – and you'll be frantically searching your purse for some Pepto. It features smoked brisket, rib meat, jalapeno-cheddar smoked sausage, bacon, cheddar cheese, barbecue sauce, and homemade ranch.
Hooters might be famous for its wings (and certain other things), but it has its own slate of outrageous burgers. The king of 'em all is the simple but massive Big Hootie, which serves up not one but two half-pound patties on a toasted brioche bun with lettuce, tomato, onions, and cheese.
If you can't decide between a burger and wings, now you don't have to. With the Buffalo Wing Burger, Dave and Buster's has topped an already-massive angus-blend patty with chicken tenders tossed in buffalo sauce, then added blue cheese and onion straws. There's also celery, so this totally counts as health food, right?
Shield your eyes, nutritionists. The Whole Hog burger features four different kinds of meat — ground beef, sausage, bacon, and pepperoni — for more than a pound in total. There are also three cheeses, pickles, and a generous dollop of garlic mayo. Add fries and you're taking in close to 3,600 calories in a single meal, not to mention more than 250 grams of fat.
