Divide the beef into 4 even balls. Mold so cohesive and tacky, Shape into balls. Refrigerate until ready to cook.

Shape each ball into disk shape patty about 3“ across. Season with salt and pepper, flip over and create large mound of onions on top.

Place patties in heated skillet. Smash the burger and onion with stiff spatula to form 4 1/2 - 5” patty. Replace stray onions back on top. Season lightly with salt and pepper.
