Ingredients
- ½ lb ground beef, 80/20
- 2 slice American cheese slices
- 2 bun hamburger buns
- ½ medium yellow onion
- 3 tablespoon mayonnaise
- 1 tablespoon ketchup
Instructions
- 1
Slice the onion crosswise into thin rings about the thickness of a coin, roughly 1/8-inch thick.
- 2
Stir together the mayonnaise and ketchup in a small bowl until evenly combined—this is your special sauce.
- 3
Divide the ground beef into 2 equal portions, then gently shape each into a loose ball about the size of a golf ball; do not pack or overwork the meat.
- 4
Place a 10-inch or 12-inch skillet over medium-high heat, then add 1 tablespoon of oil and let it heat until it shimmers and slides quickly across the pan, about 2 minutes.
- 5
Place both beef balls in the hot skillet, then use the bottom of a sturdy glass or metal spatula to press each down hard into a thin patty about 5 inches wide, applying firm downward pressure for 5 seconds without moving the spatula.
- 6
Scatter the sliced onions evenly over both patties, pressing them gently onto the meat with your spatula so they stick.
- 7
Cook without moving the patties for 2 to 3 minutes, until the bottom is deeply browned and crispy-looking around the edges.
- 8
Flip each patty with your spatula, pressing down once more to keep it thin and crispy.
- 9
Immediately lay one cheese slice over each patty and cook for another 1 minute until the cheese begins to melt and the underside is browned.
- 10
Transfer each patty to a clean plate and let rest for 30 seconds to set the cheese.
- 11
Spread 1.5 tablespoons of special sauce on the bottom half of each bun.
- 12
Place one cheeseburger patty on each bun, then close the burger with the top half of the bun, pressing down gently so the sauce seeps into the meat.
- 13
Serve immediately while the cheese and meat are still hot.
