After reading an article on the Depression Burger of Route 66, I decided to make one. I didn't search for any recipes but used the information in this article to figure it out. It took a couple of tries, and if you like carmelized onions with your hamburger then I recommend trying this recipe.
In my experimenting with recipe, I found a successful onion burger requires five things: thinly sliced onions, thin hamburger patties, a wide blade spatula like those used to flip homemade pancakes, a flat, smooth and sided cooking surface with a cover like a fry pan or electric skillet, and cooking burger to medium-well/well doneness.
Onion Burgers (makes 5-6 burgers)
One large onion, thinly sliced
One pound ground beef
Non-stick cooking spray if using non-stick fry pan or cooking surface
1) Peel and thinly slice onion.
2) If using non-stick fry pan or cooking surface, spray with non-stick cooking spray.
3) Arrange onion slices into 5 – 6 circles on cooking surface.
4) Bring cooking surface to medium heat level.
5) Shape hamburger into 5-6 very thin patties approximately the same size of the onion circles on the cooking surface. Once each patty is shaped, place it atop corresponding onion circle.
6) Using wide blade spatula, gently press each patty.
7) Cover cooking surface and let burgers cook for 25-45 minutes or until there is no more grease/fat.
8) Remove patties from cooking surface. Serve.
9) Store any leftovers in airtight container in refrigerator.
