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.
