Instructions
Burger Sauce:
If desired, prepare the burger sauce before you start on the burgers, up to a few days in advance. Simply combine all of the ingredients in a small bowl or jar and store it sealed in the fridge until you are ready to use.
Preheat your griddle on medium-high heat until it is smoking and reaches 425°
While the griddle is heating divide the beef into 3-ounce portions (about ¼ cup). Shape each portion into a ball. Use a mandolin or a knife to slice the onion into super thin slices. Prepare the cheese slices, buns, and be sure to have the salt and pepper close by. These burgers cook really quickly so having all of your tools and ingredients ready to go is key!
Lightly oil the griddle surface. Make 4 piles of about ¼ cup of sliced onion on the griddle, then set a ground beef ball on top of each pile. Season each ball liberally with salt and pepper.

Use a burger press to smash the meat into the onion. Hold the press while applying pressure for a few seconds then remove the press. If you find that the press is sticking to the beef, place a layer of parchment paper over the beef before pressing it.
- When the burgers are just a little more than halfway cooked through (the tops will be mostly brown, with some pink spots), use a spatula to flip the burgers to the second side. Be sure to scrape under the burger So the crispy ‘crust’ and onions stay with the burger.
- Immediately after flipping, top the burger with a slice of American cheese. and cook for an additional 1-2 minutes.8 slices American Cheese
