Heat oil or butter in a large skillet over medium heat.
Add thinly sliced onions and cook, stirring occasionally, until they are deep golden brown and caramelized, about 15–20 minutes. Remove from pan and set aside.
Form the Burgers:
Divide ground beef into 4 portions and flatten each into a thin patty (Oklahoma-style burgers are thin).
Season both sides generously with salt and pepper.
Cook the Burgers:
In the same skillet with a bit of leftover oil from the onions, cook each patty over medium-high heat.
Once the first side is browned (about 2–3 minutes), pile a generous amount of caramelized onions on top of the patty and press down lightly.
Flip carefully so the onions are pressed into the beef and cook another 2–3 minutes.
Assemble the Burgers:
Place the onion-topped patties on buns.
Add optional toppings like cheese, pickles, or condiments if desired.
Serve:
Serve immediately with fries or a side of coleslaw for a true Midwestern experience.
💡 Pro Tip: For the ultimate Oklahoma touch, press the onions into the beef while cooking—it creates a crispy, flavorful crust and juicy burger interior.
If you want, I can also give a griddle version like the ones served in classic Oklahoma diners, which makes the onions even sweeter and the burgers extra juicy.
