Step 1

First thing, slice all of the onions using a mandolin. Be sure to slice them as thin as possible. Toss them in a bowl with kosher salt and let sit for 20 minutes. Remove the onions and squeeze all of the excess water from the onions.

Step 2

During the 20 minute waiting period, roll your ground beef into equally portioned balls. About a 1/4 of a pound per. Place them in the fridge for 15 minutes.

Step 3

Fire up the griddle by turning the knobs on high, let it heat up for about ten minutes and add some oil if needed.

Step 4

While the griddle is heating up, make the burger sauce by adding mayo, ketchup, mustard, sweet relish, hot sauce, pepper and salt into a bowl and whisking it.

Step 5

Add the burger balls onto the hot griddle surface and top them with a handful of the onions. Don’t be shy, the more the better. Smash each one down where the patty is as thin as you can make it and season with your desired seasoning.

Step 6

Cook for 4 minutes and flip, once flipped, season them and after 2 minutes add the American Cheese on top. Place the top bun on top and the bottom bun on top of the top bun. Close the lid and let it steam for a few minutes.

Step 7

Remove the bottom bun off the top and add the burger sauce with pickles. Top it with a single patty, or two, and complete the burger.

Step 8

Serve and enjoy!
