Preparation Phase & Tools to Use

To execute these burgers just right, you’ll want to prep your kitchen like a short-order cook. Here are the essentials:

• Cast Iron Skillet or Heavy Griddle: This is key to achieving the deep crust on your patty and the proper browning of the onions. Cast iron holds high heat and distributes it evenly, making it ideal for frying.
• Mandoline or Sharp Knife: Getting the onions sliced ultra-thin is critical. A mandoline ensures consistent thickness, but a sharp chef’s knife will do in a pinch.
• Spatula (Preferably Metal): You’ll need this to press the onions into the beef and later to flip the burger. A firm metal spatula also helps get under the crusty edge for a perfect release.
• Mixing Bowl & Paper Towels: Use the bowl to toss your onions with a pinch of salt to draw out moisture. Paper towels are handy for patting them dry to avoid steaming.
• Burger Press or Small Plate (optional): Pressing the onions and beef firmly into the skillet gives you that signature texture. A burger press helps but isn’t essential.

With these tools in hand, you’re set to bring Oklahoma’s most iconic burger to life with crispy edges, sweet onion flavor, and gooey cheese in every bite.

Ingredients for the Oklahoma Fried Onion Burgers

Each ingredient in an Oklahoma Fried Onion Burger has a clear purpose, delivering texture, moisture, and deep, savory flavor:

• Ground Beef (80/20): The higher fat content is key to juicy patties that crisp beautifully on the outside. Leaner blends won’t deliver the same crust or flavor.
• Yellow Onions: Sliced super thin, these are the soul of the burger. When pressed into the patty, they caramelize and become sweet, crispy, and golden.
• Salt and Pepper: Simple seasoning lets the beef and onions shine without distraction.
• American Cheese: Classic melty goodness that pairs perfectly with the savory beef and sweet onions.
• Burger Buns (preferably soft brioche or potato buns): Soft buns soak up the juices without falling apart, giving just the right bite.
• Butter (optional): Toasting the buns with a little butter adds richness and texture.

How To Make the Oklahoma Fried Onion Burgers

Step 1: Prep the Onions

Use a mandoline or sharp knife to thinly slice your onions into translucent slivers. Toss them with a pinch of salt and let them sit for 10 minutes to release moisture. Pat dry with paper towels.

Step 2: Form the Patties

Divide the ground beef into loose balls (about 3 oz each). Don’t overwork them—you’ll be smashing them flat in the skillet.

Step 3: Smash with Onions

Preheat your cast iron skillet over medium-high heat. Place a beef ball in the hot skillet, then immediately pile a generous handful of onions on top. Using a spatula, press the onions into the beef, smashing it flat. Let it cook undisturbed for 2-3 minutes.

Step 4: Flip and Add Cheese

Flip the burger when the edges are brown and crispy. Cook for another 1-2 minutes. Top with a slice of American cheese and let it melt while the bottom finishes cooking.

Step 5: Toast the Buns

(Optional) In another pan or the same skillet, lightly butter the cut sides of the buns and toast until golden.

Step 6: Assemble and Serve

Place the burger patty with melted cheese and onions onto the bottom bun. Top with the other half and serve immediately—no condiments required, though a touch of mustard works great if you like.

How to Serve and Store Your Oklahoma Fried Onion Burgers

Oklahoma Fried Onion Burgers are best served hot off the skillet when the cheese is gooey, the onions are crispy, and the patty is still sizzling. Plate them up with a side of classic crinkle fries, potato wedges, or even a crunchy pickle spear for that diner-style finish.

For storing leftovers, let the patties cool completely before placing them in an airtight container. Separate layers with parchment to prevent sticking. Store in the refrigerator for up to 3 days. To reheat, use a skillet on medium heat to bring back that crust—microwaving will soften the texture too much. Avoid storing assembled burgers, as buns tend to get soggy.

Frequently Asked Questions

How thin should I slice the onions?

As thin as possible—almost translucent. This allows them to cook quickly and caramelize right into the beef. A mandoline slicer is your best tool here.

Can I use a different type of cheese?

Yes! While American cheese is traditional for its meltiness, cheddar or Monterey Jack can work if you prefer a sharper flavor.

What if I don’t have a cast iron skillet?

Any heavy-bottomed skillet can work, but cast iron really helps with achieving that browned, crispy edge. If you’re using stainless steel, make sure it’s fully preheated.

Can I make this burger with turkey or plant-based patties?

You can, but expect a different texture. Ground turkey is leaner and might dry out, while plant-based patties won’t develop quite the same crust but can still taste great with the onions.

Are condiments necessary?

Not really. These burgers are full of flavor on their own. However, a smear of mustard or a thin layer of mayo can add a bit of zip if you like.

Do I need to press the burger down when cooking?

Yes! The “smash” is key. Pressing the onions into the beef maximizes the crispy edges and allows the flavors to meld together beautifully.
