Ingredients
Units
Scale
For the Burger
- 1.5 pounds ground beef 80/20
- Salt (to taste)
- 1 teaspoon pepper
- Oil (for griddling)
- 12 slices American cheese
- 4 brioche buns
- Pickles (sliced)
For the Onions
- 2 large onions, thinly sliced
- 1 teaspoon kosher salt
For the Burger Sauce
- 1/2 cup mayonnaise
- 3 tablespoons ketchup
- 2 tablespoons yellow mustard
- 1.5 tablespoons sweet relish
- 1.5 tablespoons hot sauce
- 1 teaspoon pepper
- 1 teaspoon kosher salt
Instructions
- Prepare Onions: Slice all the onions using a mandoline to ensure thin, even slices. Toss the sliced onions in a bowl with 1 teaspoon of kosher salt and let sit for 20 minutes. Afterward, squeeze out excess water to caramelize better on the griddle.
- Form Patties: During the 20-minute onion resting period, divide the ground beef into four equal balls, approximately 1/4 pound each. Place the meat balls in the fridge for 15 minutes to help keep their shape.
- Heat the Griddle: Turn your griddle or flat-top skillet to high heat. Let it heat for about 10 minutes. Add a small amount of oil if necessary to prevent sticking. This ensures a hot surface for smashing.
- Make Burger Sauce: In a bowl, whisk together mayonnaise, ketchup, mustard, sweet relish, hot sauce, pepper, and salt until smooth. Set aside.
- Cook Patties and Onions: Place the beef balls on the hot griddle. Immediately smash each ball down as thin as possible using a spatula or burger press. Top the patties with a handful of onions. Season each patty with salt and pepper. Cook for about 4 minutes until edges are crispy and browned.
- Flip and Add Cheese: Flip the patties carefully, season the other side, and cook for another 2 minutes. During the last minute, place a slice of American cheese on each patty, allowing it to melt.
- Assemble Burgers: Remove the patties and onions from the griddle. Toast the brioche buns slightly if desired. Spread burger sauce on the bottom buns, add pickles, then place one or two cheese-topped patties. Cover with the top buns and serve immediately.
Notes
- Use a heavy-duty spatula or burger press to smash the meat as thin as possible for crispy edges.
- Ensure the griddle is very hot to achieve the characteristic seared, crispy edges of a smash burger.
- Caramelize the onions properly for a sweet, savory flavor that complements the burger.
- For extra flavor, toast the buns lightly before assembling.
- The burger sauce can be made ahead and stored in the fridge for up to 3 days.
