The best I can tell the onion burger became popular during the Depression years. Restauranteurs searched for ways to make their expensive meat go further. Onions became a popular choice as filler because they were cheap and helped keep the burger moist. Eventually customers became accustomed to burgers with onion fried in, and the practice continued even after good times returned. Today the city of El Reno holds an annual Onion Burger Day each May and fries up a 700-pound burger. But onion burgers aren't the only thing to see.
