Oklahoma Burger Ingredients

Simple ingredients and a hot griddle are all you’ll need to make an irresistible juicy burger! Also known as depression burgers or smash burgers, this classic diner fare is mouthwatering no matter the name.

You’ll need:

For The Hamburger:

½ tablespoon of vegetable oil
1 yellow onion, sliced into thin-cut half-moon shapes
1 pound of lean ground beef
Hamburger buns
Sliced American cheese
Salt and pepper
Cooked bacon, optional
Pickle chips, optional

For The Secret Burger Sauce:

¼ cup of mayonnaise
⅛ cup of ketchup
¼ teaspoon of garlic powder
⅛ teaspoon of ground red pepper
⅛ teaspoon of kosher salt
¼ teaspoon of yellow mustard
½ teaspoon of dill pickle juice
⅛ teaspoon of ground black pepper

Best Type of Onion for Delicious Burgers

WHITE ONIONS: With a strong onion flavor and crunchy texture, white onions are the perfect choice for the best burgers.

YELLOW ONIONS: With a more mild flavor and softer texture, yellow onions are a great choice for these juicy burgers as well.

VIDALIA ONIONS: This type of large onion has a sweeter flavor due to its higher sugar content. It’s considered one of the most mild onion flavors.

Onion Burger Recipe Substitutions and Additions

GROUND BEEF: Other ground meats such as lamb or venison could be used instead of beef for these onion burgers if you prefer.

SLICED AMERICAN CHEESE: Don’t like American cheese? Try cheddar cheese slices instead.

BACON: Fried bacon goes well with almost all burgers, and the Oklahoma burger is no exception.

DILL PICKLES: Add a few dill pickles to the top of the burger for an extra tangy taste.

How to Make a Fried Onion Burger

STEP ONE: Make the burger sauce by whisking together all the secret burger sauce ingredients in a small bowl. Set aside.

STEP TWO: Heat a large skillet over medium heat.

Add the vegetable oil and sliced onion. Stir.

OUR RECIPE DEVELOPER SAYS

If you choose to mix the meat with your bare hands, I highly recommend using disposable gloves. That way, you reduce the risk of cross-contamination, and it’s a lot less messy.

STEP THREE: Divide the hamburger meat into four equal parts.

Roll each part into a ball and then use your hands to flatten it into a patty.

You could also use a burger press.

Season both sides of hamburger patties with salt and pepper.

PRO TIP:

Handle the meat as little as you possibly can. The more you work the meat, the tougher it will get.

STEP FOUR: Place the hamburger patties directly on top of the onions in the hot nonstick skillet.

Apply pressure with your spatula to press the hamburgers and onions together.

STEP SEVEN: Add the optional bacon and pickles if using them.
