Oklahoma Fried Onion Burgers are a nostalgic, crispy-edged burger staple from the heartland. A Depression-era creation that maximized flavor and minimized cost, these burgers are made by smashing thin-sliced onions directly into the beef patty and cooking them until beautifully browned. The result? A juicy, flavorful burger with crispy onion edges that will transport you straight back to Grandma’s kitchen!
