You make the patties into a loose meatball shape(around 4 ounces). Ground beef 80/20 works best from what I’ve heard. Then when your pan is super hot, you throw them on and smash them super thin. Let them cook about 2 mins, then get a metal spatula to flip. Add cheese if you so desire and let it cook for another min.
The one in the pic is a double smash burger with 2 patties. Magnificent IMO. I just started this journey a couple weeks ago and I am hooked! Although I need to prob chill a bit since not exactly the most healthy thing.
