The famous fried onion burger in El Reno, Oklahoma started in the early 1900’s. During the depression, meat prices were high, as a way to beef up their patties a local place called the Hamburger Inn in El Reno started adding a handful of thinly-sliced white onions to a smaller meat patty as it cooked on the griddle. Before turning the patty, the onions would get pressed into the meat with a spatula. The addition of the onions added a ton of flavor, and poof, just like that an El Reno food tradition was born.
Before long, a handful of these places opened in El Reno, all serving the fried onion burger. Sid’s is one of the oldest places in El Reno to still make the famous burger, and they pack in customers daily.
I went to Sid’s to work on a story about hamburgers for Saveur Magazine.
Here’s my visual essay on Sid’s and the legendary fried onion burger.
Note: as an appetizer, a coney relish is added to many orders. it comes with Sid’s house-made mustard relish and is totally worth the splurge.
