Description
This Oklahoma Onion Smashburger features crispy beef smashed over sweet, thinly sliced onions, melted American cheese, and a tangy homemade sauce on a soft brioche bun. It’s a diner-style burger packed with flavor and texture that’s easy to make at home.
Ingredients
- 680 grams ground beef (80/20 blend)
- 2 large onions, thinly sliced
- 12 slices American cheese
- 6 brioche burger buns
- Pickles, sliced, to taste
- Kosher salt, to taste
- 1 teaspoon ground black pepper
- For the burger sauce:
- 120 ml mayonnaise
- 45 ml ketchup
- 30 ml yellow mustard
- 22 ml sweet relish
- 22 ml hot sauce
Instructions
- Thinly slice the onions using a mandolin. Toss with kosher salt and let rest for 20 minutes, then squeeze out excess moisture.
- Divide ground beef into 6 loose balls (about 110g each) and refrigerate for 15 minutes.
- Preheat griddle or cast iron skillet on high heat for 10 minutes. Lightly oil if necessary.
- In a bowl, whisk together all burger sauce ingredients until smooth. Set aside.
- Place beef balls on the hot griddle, top with a handful of onions, and smash flat using a spatula. Season with salt and pepper.
- Cook for 4 minutes, then flip so the onions are on the griddle. Cook another 2 minutes.
- Add a slice of cheese to each patty and top with brioche buns. Cover briefly to melt the cheese and warm the buns.
- Assemble burgers by spreading sauce on buns, adding pickles, and stacking one or two patties per burger.
- Serve immediately.
Notes
- Use a hot skillet or griddle to get crispy edges on the patties.
- Salted onions caramelize better than raw, unsalted ones.
- Try cheddar or pepper jack instead of American cheese for variation.
- Use a cast iron pan if a griddle isn’t available.
- Keep sauce refrigerated for up to one week.
