  • Remove the onions from the pan.
  • Place one of the ground beef patties into the center of the pan, use the burger press to spread the ground beef out into a thin patty. Cook for one minute.

Notes

  • Nutrition facts are just an estimate of the ingredients listed.
  • To easily use the press, place a piece of parchment paper on top of the burger before smashing. 
  • Don’t own a burger press, try using a flat measuring spoon to smash the burger flat
  • For double burgers, only place cheese onto one of the patties.
