Oklahoma Onion Burgers

Divide the beef into 8 equal portions and form into balls.

Heat a heavy bottomed pan/skillet over medium-high heat, place the balls into the pan, smash them down to about 1/3 inch thick, and season with salt and pepper to taste. (You may need to do this in batches.)

Spread the onions on top and let the meat cook until the meat gets golden brown and caramelized before flipping.

Let the onions cook until they start to get tender, about 1 minute, place the cheese on top, followed by the buns, cover, and let cook until the onions start to brown, 1-2 minutes.

Assemble the burgers and enjoy!

Tip: Slice the onions thinly using a mandoline.

Option:
Place the sliced onion in a wire mesh strainer, mix with some salt, and let it sit for 30 minutes before squeezing out the excess moisture and patting dry. This step helps remove moisture from the onions and helps them to caramelize quicker.
