What Kind of Onions Should I Use for Oklahoma Fried Onion Burgers?

Yellow onions are the classic choice for Oklahoma Fried Onion Burgers. Their natural sweetness intensifies as they cook, creating a deep caramelized flavor. For best results, slice the onions super thin (a mandoline is your friend here). If you prefer a bit of bite, try a mix of yellow and white onions. Red onions can be used in a pinch, but yellow will give you that signature sweet-savory finish.

How To Make the Oklahoma Fried Onion Burger

Step 1: Prep the Onions & Beef

Use a sharp knife or mandoline to slice the onions extremely thin. Divide the ground beef into 4 equal balls (about 4 ounces each). Have salt and pepper ready.

---

Step 2: Shape & Smash

Heat a cast-iron skillet or griddle over medium-high. Place each beef ball onto the hot skillet. Immediately top each with a mound of onions, pressing the onions firmly into the beef with a spatula until the patty is about 1/2-inch thick. Season generously with salt and pepper.

---

Step 3: Sear & Caramelize

Cook the patties (onion-side down) for 2-3 minutes without moving, until the onions are deeply golden and crispy around the edges. Flip the burgers so the onions are now on top.

---

Step 4: Add Cheese & Steam

Top each patty with a slice of American cheese. Add a splash of water to the pan and cover with a lid or baking sheet for 30 seconds to melt the cheese and soften the onions further.

---

Step 5: Toast the Buns

While the cheese melts, butter the buns and toast them in a separate skillet or under the broiler until golden brown.

---

Step 6: Assemble & Serve

Place each cheesy patty on a toasted bun. Add any desired toppings, then top with the other half of the bun. Serve hot and enjoy every juicy, oniony bite!

Frequently Asked Questions

1. Can I use a different type of cheese?

Absolutely! While American cheese is classic, feel free to swap in cheddar, Swiss, or pepper jack for a new twist. Just make sure it melts easily.

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

Any heavy-bottomed skillet or flat griddle will work. The goal is even, high heat to caramelize the onions and get crispy edges on the patties.

3. Can I make these burgers ahead of time?

You can prep the onions and shape the beef balls ahead, but for best texture, cook and assemble just before serving. Leftovers can be reheated, but the fresh-off-the-skillet taste is unbeatable.

4. Can I freeze Oklahoma Fried Onion Burgers?

It’s best to freeze the uncooked patties and onions separately. Thaw in the fridge, then cook as directed. Cooked burgers can also be frozen, but the texture is best fresh.

5. Are these burgers gluten-free?

Simply use gluten-free buns, and you’re set! All other ingredients are naturally gluten-free.
