It’s the first Saturday in May, and the air in downtown El Reno, Oklahoma, doesn't just smell like spring—it smells like caramelized onions and nostalgia.

In this episode of the Only in OK Show, we’re previewing the 38th Annual El Reno Burger Day Festival (May 2, 2026). As the "Official Birthplace of the Fried Onion Hamburger," El Reno turns a Great Depression-era necessity into a world-renowned delicacy. We dive deep into the history of how Ross Davis of the Hamburger Inn used paper-thin onions to stretch meat during the 1930s, creating a culinary icon in the process.

What’s on the menu for this episode:

The 850-Pound Beast: Discover the engineering marvel behind the world's largest fried onion burger, featuring 250 lbs of beef, 150 lbs of onions, and a custom-baked 350 lb bun.

The Science of Flavor: We talk the "Maillard reaction"—why smashing onions into beef fat creates the ultimate Oklahoma flavor profile.

More than Just Meat: From the USTAF Sanctioned Bun Run to the massive car show on Rock Island and the Main Stage music, we cover the full festival experience.

The Fried Onion Burger Holy Trinity: While at the fest, you have to visit the legends: Sid’s Diner, Robert’s Grill, and Johnnie’s Hamburgers & Coneys.

Route 66 News: We also discuss the neon glow returning to the Mother Road as the Cotton Boll Motel sign gets a new lease on life.

Whether you're a foodie, a Route 66 road-tripper, or a local looking for a "Bun Run," this episode is your ultimate guide to El Reno Burger Day.
