You Won't Believe How These 14 Restaurants Top Their Burgers (Slideshow)

This Boston restaurant and tavern offers a burger featuring one of their signature dishes: White Trash Dip. The dip includes American cheese, green chiles, jalapeños, diced tomatoes, diced onions, and corn tortilla chips — the White Trash Burger is topped with the dip plus a stack of beer-battered onion rings. 

Daniel Boulud is the godfather of offering high-end burgers in fine dining restaurants, and his DBGB serves a burger so luxurious it demands a spot on this list. The Frenchie begins with premium beef expertly cooked and topped with crispy pork belly, caramelized onions, arugula, cornichons, and mustard. 

This burger is topped with bacon, fried banana slices dusted with cinnamon sugar, and a slather of creamy peanut butter. 

This Chicago hot spot specializes in serving up badass burgers in a hard-rock-inspired setting. The Megadeth is just one of many outrageous burgers on Kuma's menu, but between the chorizo, red potato hash, pico de gallo, cayenne avocado cream, and tortilla strips, it's one that takes creativity to the next level.

Wiener and Still Champion is upping the ante with their newly unveiled deep-fried gravy burger. When you order this ⅓-pound burger, a disk of gravy will be breaded and fried to order, so that when you take your first bite, the warm, molten gravy oozes out and coats the burger. Think of it as the burger equivalent of a soup dumpling.

Another burger hailing from Kuma's Corner, the Brujeria is topped with cream cheese- and chorizo-stuffed jalapeño poppers, Cheddar cheese, and charred tomato salsa. It's certainly messy to eat, but the cleanup is well worth it.

This spirited spot, with restaurants in 11 other locations ranging from Orlando, Fla., to Portland, Ore., serves mammoth-sized burgers. One of their unique specialties is the Daddy Mac, which begins with their giant patty layered with Mary's special sauce, lettuce, pickles, and a serving of macaroni and cheese. As if the creation isn't cheesy enough, they top it off with slices of melted American cheese.

This ¾-pound burger, comprised of Black Angus beef, is topped with a scoop of vanilla ice cream and drizzled with hot fudge sauce. It's not unheard of to dip French fries in a milkshake (in fact, Wendy's fries dipped in a Frosty is a cult classic combination), but combining the whole burger and fries meal with a sundae? That's a whole new concept.

This outrageously large burger is big enough to share... with plenty of friends. It starts with a burger topped with melted provolone cheese, then topped with a mountain of French fries, tomato, and sweet-and-sour coleslaw, all piled into crusty Italian bread. It's a complete meal in a single bite. 

So this burger cheats the list a little bit because the star of the show is stuffed inside the burger rather than perched on top. That said, this burger has plenty to offer by way of toppings as well — the patty is stuffed with a combination of sautéed shrimp and Gouda cheese, then topped with a grit cake, Andouille sausage, and tomato beurre blanc sauce.

26 Beach claims to be the originator of the sushi hamburger, and this surf-and-turf combination is quite a feat. Chef Katsu's Original California Roll Burger includes an Angus beef burger topped with snow crab, avocado, pickled ginger, baby mixed greens, tomato, nori strips, and shoyu-wasabi aioli. 

PYT is renowned for its amazing burgers and wild toppings, but the everyday menu is actually rather straightforward and not too crazy. If you're looking for the truly outlandish creations, you'll need to check out their weekly specials. For example, take the Beerger: a beef patty topped with cheddar, pickles, mustard-dill aioli, and pretzel-coated "fried PBR." How do you deep-fry beer? Good question. First, a small cup of beer gets frozen, then it's sealed inside a wonton wrapper with a slice of cheese. Next comes a dip in eggs, flour, and garlic, onion, and sesame pretzel crisps before it hits the deep-fryer. You need to be over 21 if you want to order this!

This super-popular food truck (now with a brick-and-mortar location as well) makes some wild burgers, but did you ever consider topping yours with peanut butter, jelly, bacon, and sriracha? It's sweet, spicy, smoky, nutty, and absolutely insane. 

Matt's has been around for so long (84 years) that it's on the National Register of Historic Places, and their "nutburger" is one of the original crazy-topped burgers. It's simple, but still super-creative. A fresh beef patty (seared on the original cast iron griddle) gets placed on a bun, then a combination of chopped salted peanuts and Miracle Whip gets spooned on top. Believe it or not, all the flavors work perfectly together.
