How to Make Depression Era Cheeseburgers
- Heat the skillet
Lightly spread the oil inside a large cast iron skillet using a paper towel. Heat over medium-high until the skillet is hot and just beginning to smoke. - Smash the burgers
Add both balls of beef to the skillet and immediately top with a large handful of the sliced onions on top of the burger. Using the back of a sturdy spatula, press everything down firmly until the burger balls are very thin and fully flattened. - Season and sear
Season generously with salt and pepper. Cook undisturbed until the meat begins to brown and crisp around the edges. You want a good sear on the beef patties. - Flip carefully
Using a stiff spatula, carefully flip each burger, making sure to scrape up all the browned bits from the skillet. Reduce heat to medium. - Steam and melt
Let the burgers cook for about 1 minute until the onions begin to soften. Add a slice of American cheese to each burger. Place the bottom bun directly on top of the cheese, then rest the top of the top bun upside-down over the bottom bun so it can steam in the onion vapors. - Finish cooking
Cook for 3–4 minutes, until the onions are deeply caramelized and the buns are soft and warm. - Assemble and serve
Transfer the top buns to a plate and add burger sauce or condiments if desired. Lift the onions, burger, and bottom bun together and place on the plate. Top with the bun and serve immediately.

Frequently Asked Questions
Why is it called a Depression Era burger?
These burgers stretch a small amount of beef by smashing it thin and pairing it with onions, making them filling and affordable—perfect for lean times.
Can I make these without cast iron?
Yes, but cast iron gives the best crust. A heavy stainless steel skillet works well too.
Can I double the recipe?
Absolutely—just work in batches so the skillet stays hot.
Storing & Reheating Leftovers
These burgers are best enjoyed fresh, but leftovers can still be saved with good results.
To store:
Allow the burgers to cool completely. Store the cooked single patty with onions in an airtight container with lid in the fridge for up to 3 days. For best texture, store the buns separately.
To reheat:
Reheat the burger and onions in a skillet over medium heat until warmed through. Add a splash of water and cover briefly to help re-steam the meat without drying it out. You can also microwave in short bursts, but the skillet method keeps the edges crisp.
Freezing:
Freezing is not recommended for assembled burgers, but the cooked smashed patties with onions can be frozen for up to 2 months. Thaw overnight in the refrigerator and reheat in a skillet before serving on fresh buns.
Tip:
If you know you’ll have leftovers, hold off on adding condiments until reheating to keep the buns from becoming soggy.
