Classic Smash Burgers

Instructions

1. 1

   Divide the beef into 8 loose balls (about 3 oz each); do not pack them tight. Stir mayo and ketchup together for a quick burger sauce.

2. 2

   Butter the cut sides of the buns and toast them in a large cast-iron skillet over medium heat until golden, then set aside.

3. 3

   Turn the heat to high. Add 2-3 beef balls, then press each one flat with a sturdy spatula until about 1/4 inch thick. Season with salt and pepper.

4. 4

   Cook 2 minutes until the edges are deeply browned and crispy, scrape under each patty, flip, and top with half a cheese slice. Cook 1 minute more.

5. 5

   Stack two patties per bun with sauce, thin-sliced onion, and pickles. Kids can skip the onion and pickles and keep it plain with ketchup.
