15 Historic Burger Joints Across America - Iqraa news

El Reno, Oklahoma

Established: 1926 

Oklahoma fried onion burgers were born in El Reno, and even though Robert’s isn’t the originator (that would be Homer and Ross Davis at the now-closed Hamburger Inn), it’s probably the place in town that’s been doing them the longest.  

The Oklahoma onion burger is, for those uninitiated to the regional burger style, a simple work of wonder: A whole lot of thin-sliced onions are smashed into a burger patty, and then when flipped, begin to caramelize in the grease. If done right, about half your patty is made of onion. Mouth watering yet?
