Preparation

Step 1

Place onion slices in a small bowl and cover with salt.

Mix the onions and salt well, separating the onions into rings, and set aside for at an hour.

For quicker assembly, separate buns and place them together with the middle of the bottom bun facing down, and the middle of the top half touching the brown bottom of the bun.

Form meat into equal size balls and place on a plate near your griddle.

Squeeze onions to remove any remaining liquid. Dump salty liquid from the bowl. Rinse the onions if desired, just make sure to squeeze them once more to remove excess water. I do not rinse.

Set electric griddle to high and allow griddle to get very hot. If using a skillet, use medium high heat and preheat skillet.

Once griddle is screaming hot, add 4 to 6 burger balls spaced about 4 inches apart on griddle. Top meat with onions.

Let meat and onions sit for about a minute on the hot griddle.

Smash the burgers as flat as possible with a spatula. This is where a sturdy spatula comes in handy. You want the burger thin so they cook rather quickly.

Once the burgers look like they are mostly cooked through, flip them over.

Cover each burger with one bun, inside of the bottom half touching the burger, inside of top half touching the bottom of the bottom half.

Cover with an inverted cake pan or large lid.

Cook burgers for another 2 minutes.

Carefully remove the cake pan or lid. Use kitchen tongs if necessary, this covering will be very hot.

Slide spatula under the burger and onions.

Carefully remove the top half of the bun and place it under the spatula and slide the burger with the bottom half of the bun onto the top bun.

Place on a plate and quickly cover with mustard and pickles. Add cheese now if using.

Eat while hot.
