During the Dust Bowl years that made many Okies into migrants (see John Steinbeck), Oklahoma grill cooks began serving onion burgers. El Reno, about 30 miles west of Oklahoma City, claims to be the birthplace. According to legend, cook Ross Davis invented the onion burger at the Hamburger Inn on Rte. 66 in downtown El Reno. He piled half a shredded onion on top of a nickel meat patty and smashed them together with a spatula. Presto! The onions transformed the wafer-thin patty into a substantial meal. Three diners in El Reno—Sid’s Diner, Johnnies Grill, and Robert’s Grill—specialize in the dish. The town also holds a Burger Day Festival in May.
The dust storms are gone, but a taste for onion burgers remains. In fact, one of the hottest chains in Oklahoma City is Tucker’s Onion Burgers (tuckersonionburgers.com), with three outlets. Tucker’s brings diner food into the 21st century with its polished modern settings that evoke the mythical malt shop past of the “Happy Days” era. That’s a familiar meme—think of the Sonic or Johnny Rocket chains.
Tucker’s is big on corporate responsibility. The beef is “ethically produced by regional growers” and the potatoes are hand-cut every morning and fried in peanut oil. The company goes to great lengths to reduce water use and electricity and recycles everything. The best modern twist is that every order slip is a paper bag. When the order is ready, the cooks slip it into the bag to go. Although Tucker’s does offer a salad and a turkey burger, most customers choose between single or double burgers, with cheese or without. Drinks include homemade lemonade and canned local craft beer. The burgers are delicious enough to live up to the hype.
Thrill of the grill
In fact, they were so good that when we got home we decided to adapt the onion burger idea to the charcoal grill, since meat always tastes better with a little smoke. Smashing thin-cut raw onions into burger on a hot grate was a non-starter. So we tried something different. We sliced a Bermuda onion 1/8” thick with an adjustable chef’s mandoline. Then we sweated the sliced onion with a little bit of oil and salt in a cast iron skillet until the pieces were soft. We drained them on a paper towel. When the onions were cool, we folded them into 12 ounces of ground beef (85 percent lean) and made two patties.
The onion made the burger a little “loose,” so we cooked them well on one side before flipping. A slice of cheese melted on top for the last 30 seconds helped to hold the burgers together to lift them onto buns. On balance, the onion was more distributed through the meat, and therefore a little more subtle than in a traditional onion burger. Those Dustbowl Okie grill guys were clearly onto something.
