| 500 g | ground beef |
| 4 slices | melting cheese |
| 4 | burger buns |
| ½ head | iceberg lettuce |
| mayonnaise (for serving) | |
| ketchup (for serving) | |
| dill pickle (for serving) | |
| salt | |
| pepper | |
| vegetable oil |
Heat a cast-iron pan over medium-high until very hot, then lightly brush with vegetable oil. Divide ground beef into equal portions.
Place half the portions in the pan and smash flat with a spatula to form patties approx. ½ in. (1.5 cm) thick. Season with salt and pepper and let cook until edges are very brown, approx. 2 min. Flip, season again with salt and pepper, and place a slice of cheese on top of each patty. Cook until cheese melted and burgers are medium-rare, approx. 1 min.
In the meantime, toast the buns in a toaster or in the oven. Slather the bottom bun with mayonnaise, and the top bun with ketchup. Shred the iceberg lettuce with a knife. Place the patties on the bottom bun and top with pickles, lettuce, and the top of the bun. Serve immediately and enjoy!
