On Friday, I received my “Cook’s Country” magazine in the mail and was very excited to see this recipe for ‘fried onion burgers’. We love caramelized onions, as well as a good burger, so I thought I’d give these a try.
Oklahoma Fried Onion Burgers are incredibly easy to make and insanely delicious. The key to making these mouth-watering burgers featured in Cooks Country is to smash thinly sliced onions into the ground beef before cooking. The result is golden caramelized onions embedded a perfectly cooked burger!
Preparing The Onions For The Oklahoma Fried Onion Burgers:
The most time-consuming part of making these burgers was prepping the onions to remove as much moisture as possible. The reason for doing this is that the onions won’t get hot enough to brown with all their liquid.
I started by cutting the onion in half, pole to pole, and slicing it into 1/8-inch slices. Then, I combined the sliced onions with some Kosher salt and placed them in a wire mesh strainer set over a bowl. After about 30 minutes, I dumped the onions into a clean dish towel and squeezed them dry. I was amazed at the amount of liquid that came out.
- 1 large onion, peeled, halved and thinly sliced
- salt and pepper
- 1 lb ground beef
- 1 tablespoon butter
- 1 tablespoon vegetable oil
- 4-8 slices American cheese
- Mayo, mustard and pickles, for serving
- 4 hamburger buns, toasted
- Combine the onion slices and 1 teaspoon of salt in a bowl and toss to combine. Transfer the onions to a colander and let sit for 30 minutes, tossing occasionally. Transfer the onions to a clean dish towel, gather the edges together and squeeze out as much liquid as you can from the onions. Do this over the sink or a large bowl since the onions will have quite a bit of liquid in them.
- Divide the onions into 4 separate mounds on a rimmed baking sheet. Form the beef into 4 lightly packed balls. Place the beef balls on top of the onion mounds and flatten the beef firmly (use your palm) so the onion adheres to the beef. The patties should measure 4 inches in diameter. Season the beef generously with salt and pepper.
- Melt the butter with the oil in a 12-inch skillet over medium heat. Using a large spatula, transfer the patties to the skillet, onion side down. Cook for 6-8 minutes, until the onions turn a deep golden brown and begin to crisp around the edges. Flip the burgers, then increase the heat to high and cook until well browned on the second side, about 2 minutes.
- Add 1 or 2 slices of cheese to each burger and allow to melt. Add mayo, mustard and pickles to the top buns, then place each burger on a bottom buns. Serve immediately.
