How to Make Oklahoma Onion Smash Burgers Recipe
Step 1: Prep the Onions
Start by slicing your large yellow onion super thin—think paper-thin. Using a mandoline here can be a game changer. These delicate slices not only cook quickly but also develop into a sweet, caramelized base that sets this recipe apart from ordinary burgers.
Step 2: Form the Meat Balls
Divide your ground beef into 4 equal portions, rolling each into a loose ball without seasoning yet. This approach lets you get that perfect smashing action on the griddle to maximize crispy edges.
Step 3: Heat the Griddle or Skillet
Preheat a cast iron skillet or griddle over medium-high heat for that ideal cooking surface. Add a little butter or oil to prevent sticking and enhance flavor, ensuring your patties come out with a golden brown crust.
Step 4: Smash the Burgers
Drop a generous pile of those thinly sliced onions directly onto the hot griddle. Quickly place one beef ball on top and smash down hard with your spatula or burger press until thin and wide. Pressing the onions into the beef helps them cook right alongside the meat, infusing every bite with sweetness.
Step 5: Cook Until Crispy
Let your burger cook undisturbed for 2 to 3 minutes until the edges develop a deep brown crust. Then flip the patty so that the onions are now in contact with the griddle; cooking for another 1 to 2 minutes caramelizes the onions perfectly and helps them stick beautifully to the patty.
Step 6: Add Cheese
During the last minute of cooking, layer on a slice of American cheese. Cover the patty with a lid or metal bowl to trap heat and melt the cheese to gooey perfection—this step truly ties together all the flavors.
Step 7: Toast the Buns
Lightly toast your burger buns face-down on the griddle or in a separate skillet until golden and slightly crisp. This adds texture and helps prevent soggy buns when you assemble your masterpiece.
Step 8: Assemble
Place your onion-smashed burger patties carefully onto the bottom buns. Add any optional toppings like tangy pickles or a smear of mustard, then crown with the top bun. Serve immediately for an unforgettable burger experience.

FAQs
Can I use a different type of cheese in the Oklahoma Onion Smash Burgers Recipe?
Absolutely! While American cheese melts beautifully and has that classic burger vibe, feel free to experiment with cheddar, pepper jack, or even Swiss for unique flavor profiles.
Why do the onions need to be so thinly sliced?
Thinly slicing ensures the onions cook quickly and caramelize without burning, creating a sweet, tender layer that enhances the burger’s overall flavor and texture.
Is it necessary to smash the burger on top of the onions?
Yes, smashing the beef onto the onions presses their flavors together, helping the onions stick to the patty and caramelize perfectly alongside the meat.
Can I make these burgers without a griddle or cast iron skillet?
You can use any heavy-bottomed skillet that retains heat well. Just make sure it’s hot enough to create that crispy crust while cooking the onions simultaneously.
How do I prevent the buns from getting soggy?
Toasting the buns on the griddle or skillet before assembling helps create a barrier against moisture, keeping your burger perfectly handheld and deliciously satisfying.

Description
Oklahoma Onion Smash Burgers feature a unique technique of smashing thinly sliced onions and ground beef together on a hot griddle, creating a flavorful, crispy-edged patty layered with sweet caramelized onions. This quick and easy recipe yields juicy, cheesy burgers with a perfectly toasted bun, ideal for a satisfying homemade meal.
Ingredients
For the Burgers
- 1 lb ground beef (80/20 blend recommended)
- 1 large yellow onion, very thinly sliced (preferably using a mandoline)
- Salt and pepper, to taste
- 4 slices American cheese or cheese of choice
- Butter or oil for the griddle
For Serving
- 4 burger buns
- Optional toppings: pickles, mustard, ketchup, lettuce
Instructions
- Prep the Onions: Slice the large yellow onion as thin as possible, ideally using a mandoline for paper-thin slices. This ensures quick cooking and helps create that sweet caramelized onion layer under the burger.
- Form the Meat Balls: Divide the ground beef into 4 equal portions. Roll each portion into a loose ball shape without seasoning; this helps in achieving a thin, crispy patty once smashed.
- Heat the Griddle or Skillet: Preheat a cast iron skillet or griddle over medium-high heat. Lightly grease the surface with butter or oil to prevent sticking and promote even cooking.
- Smash the Burgers: Place a small pile of the thinly sliced onions directly onto the hot griddle. Immediately place one beef ball on top of the onions and smash it down firmly with a spatula or burger press until very thin and flat. Press the onions into the meat. Season generously with salt and pepper to enhance flavor.
- Cook Until Crispy: Allow the patties to cook undisturbed for 2 to 3 minutes until the edges turn brown and crispy. Flip the patty carefully so the onions are now on the bottom and cook for an additional 1 to 2 minutes. This step caramelizes the onions and ensures they stick beautifully to the patty.
- Add Cheese: Place a slice of cheese on top of each patty during the last minute of cooking. Cover the skillet with a lid or metal bowl to help the cheese melt evenly without drying out the burger.
- Toast the Buns: While the burgers finish cooking, toast the burger buns face-down on the griddle or in a separate skillet until golden brown for added texture and flavor.
- Assemble: Place the onion-smash patties on the bottom halves of the toasted buns. Add your preferred optional toppings such as pickles, mustard, ketchup, or lettuce. Top with the other bun halves and serve immediately for best taste.
Notes
- Using a mandoline for slicing onions ensures they are thin enough to cook quickly and caramelize properly.
- Pressing the onions into the meat helps to lock in flavor and texture, creating a signature crispy edge.
- Use an 80/20 ground beef blend for optimal juiciness and flavor balance.
- Covering the burger with a lid during cheese melting helps achieve a smooth, melty topping.
- Feel free to customize toppings based on personal preference including lettuce, pickles, or various condiments.
