How to Make Oklahoma Onion Smash Burgers Recipe

Step 1: Prepare the Meat and Onions

Start by dividing your ground beef into four equal parts and loosely roll each into balls; packing tight will make it harder to get that perfect smash. Thinly slicing the onion is key — the thinner, the better they’ll caramelize under heat, so slice them carefully and set aside. This prep makes all the difference for that classic onion-infused patty flavor.

Step 2: Heat the Skillet and Oil

Heat a sturdy cast iron skillet or griddle over medium-high heat, then add the vegetable oil. A hot skillet is essential for that crispy crust, so be patient and wait until the oil is shimmering hot before you start cooking. This step is what gives your Oklahoma Onion Smash Burgers Recipe that signature sear and texture.

Step 3: Smash and Cook the Burgers

Place one ball of beef on the skillet, then generously pile sliced onions on top. Using a heavy spatula, press the beef and onions firmly flat against the skillet, smashing everything together. Season with kosher salt and black pepper. Cook for 2-3 minutes without moving it, allowing the bottom to get nice and crispy. Flip the patty so the onions that were on top are now underneath, cooking another 1-2 minutes to finish caramelizing the onions and the beef.

Step 4: Melt the Cheese and Toast the Buns

Add a slice of American cheese on top of each burger and cover the pan briefly to help the cheese melt perfectly. While the cheese melts, toast your buns in butter on another pan or in the oven until golden and slightly crisp, adding a buttery richness that pairs wonderfully with the savory patties.

Step 5: Assemble and Serve

Place each cheesy, onion-packed patty on a toasted bun and dress with your favorite optional toppings like pickles, mustard, ketchup, or mayonnaise. Serve immediately so you can enjoy the burger hot and juicy, just like it should be!

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftover patties or extras, store them in an airtight container in the fridge for up to 3 days. Keep buns separate to avoid sogginess. Reassemble just before eating to preserve the burger’s texture and flavor.

Freezing

You can freeze cooked patties by wrapping them tightly in plastic wrap and placing them in a freezer bag. Freeze for up to 2 months. Thaw overnight in the fridge before reheating for best results. Avoid freezing assembled burgers to keep buns fresh.

Reheating

For reheating, use a skillet over medium heat to warm the patties gently. Add a small splash of water to the pan and cover it to keep the burgers moist while reheating. Toast the buns fresh to maintain that crunch. Avoid microwaving if you can, to keep the crisp edges intact.

FAQs

What makes this the “Oklahoma” Onion Smash Burgers Recipe?

The hallmark of the Oklahoma onion burger is that the sliced onions are smashed directly into the patties as they cook, infusing every bite with caramelized sweetness. This technique originated in Oklahoma and creates a unique texture and flavor profile distinct from other smash burgers.

Can I use a different type of onion?

Yellow onions work best due to their balance of sweetness and sharpness when cooked. You can try white onions for a milder taste or red onions for a bit more bite, but thin slicing is still crucial to mimic that authentic Oklahoma Onion Smash Burgers Recipe texture.

Why is a cast iron skillet recommended?

Cast iron holds and distributes heat evenly, which is essential for getting the perfect crispy crust on your smash burgers. It also withstands the high heat needed to caramelize onions without burning, making it ideal for this recipe.

Can I make these burgers ahead of time?

While you can prepare patties and slice onions ahead, the best flavor and texture come from cooking and assembling the burgers fresh. If needed, you can store patties cooked and reheat as described, but toast buns just before eating.

Are there vegetarian variations for this recipe?

This recipe is specifically designed for ground beef, but for a vegetarian twist, you could experiment with plant-based patties and caramelized onions pressed in similarly. Keep in mind, the classic Oklahoma Onion Smash Burgers Recipe’s charm comes from the beef-onion combination.
