A beef patty pressed onto shredded onions on an Oklahoma City flat-top griddle, caramelizing into a salty, sweet crust that defines Depression-era ingenuity.

The Oklahoma onion burger dates to the 1920s, when short-order cooks in western Oklahoma pressed shredded onions into thin beef patties on a flat-top griddle to stretch ground beef during hard times. The technique gained wide recognition in El Reno, where diners codified the style: onions smashed into raw beef so they caramelize into the meat. Tucker's Onion Burgers brought that tradition to OKC, preserving the flat-top method. El Reno hosts an annual onion burger festival, and Tucker's keeps the style alive with thin patties, American cheese, and a soft white bun.

Oklahoma Fried Onion Burger · Tulsa

A loose-ball of ground beef pressed flat on a hot griddle with a handful of thinly sliced raw onions pushed directly into the surface of the patty as it cooks. The onions caramelize into the meat, and the underside develops a lacquered crust. It is served on a toasted white bun with yellow mustard, dill pickles, and optional American cheese.

The fried onion burger was born in Depression-era Oklahoma around 1926 in El Reno, where a cafe owner discovered that pressing onions into the beef stretched a small amount of ground meat further. The technique spread across Oklahoma and became a regional standard. Tucker's Onion Burgers carries the tradition to Tulsa with a smash-burger interpretation on a flat-top griddle.
