When I grill burgers, I usually go the Ron Swanson route. As the legendary meat-lover once said when he served dinner, “ It’s a hamburger made out of meat on a bun with nothing. Add ketchup if you want. I couldn’t care less.”  

I am firmly anti-gimmick burger. A well-grilled patty on a soft bun is already a fine dish that needs little embellishment. So every time I see a new version with foie-gras filling or doughnut buns, I cringe. 

But I will always hold a place in my heart for the slugburger. A Depression-era hack meant to stretch meager meat supplies, the recipe combines ground beef or pork with potato flour. While that might sound unappetizing, the result is a beautifully crispy-yet-juicy patty. 

The slugburger is not alone. From a Prohibition-era speakeasy that still slings bitters-filled patties to a roadside stand that’s carrying on a century-old tradition of steaming burgers, American history is filled with unusual burgers born of unusual times.

Yes, an unadorned burger can be a beautiful thing. But for anyone looking to mix things up at their July Fourth barbecue, here are six unique burgers that come with flavor and history.

Including Lummis Home (“El Alisal”), Old Zoo Picnic Area, and Ferndell Nature Museum
