Ingredients
  

Main Ingredients
  • 1 lb Ground Chuck (80/20) 450g, cold and divided into 4 spheres
  • 1 large Yellow Onion 300g, shaved paper-thin
  • 4 slices Yellow American Cheese For maximum ooze
  • 2 total Brioche Buns Split and ready for toasting
  • 1 tbsp Neutral Oil 15ml, high smoke point
  • to taste Kosher Salt and Black Pepper Used generously for crust formation

Equipment

  • 1 Cast Iron Skillet Essential for high heat retention.
  • 1 Metal Spatula Must be stiff and without slots for smashing.
  • 1 Mandoline slicer Used to achieve paper-thin onion slices.

Method
 

Preparation
  1. Using a mandoline, shave the yellow onion into translucent, paper-thin slices.
  2. Gently roll the 80/20 beef into four loose balls (115g each). Do not press into patties yet.
Cooking
  1. Heat a cast iron skillet until smoking. Place beef balls in pan, top with a massive pile of onions, and smash completely flat with a heavy spatula.
  2. Season with salt and pepper. Cook for 2 minutes until lacy edges appear. Scrape and flip so onions are underneath.
  3. Add American cheese. Stack patties and place buns on top of the meat to steam for 1 minute before serving.

Notes

Keep the beef cold until the moment it hits the pan for the best crust.
Use a high-smoke point oil to avoid bitter flavors from burnt oil.
