Smashed Patty Burger

Instructions

1. 1

   Divide the ground beef into 4 equal portions (about 125g each). Roll each portion into a loose ball - don't overwork the meat.

2. 2

   Slice the onion very thinly into rings. Butter the inside of each burger bun.

3. 3

   Heat a cast iron skillet or heavy griddle over high heat until smoking hot.

4. 4

   Place the beef balls on the hot surface, leaving plenty of space between them. Immediately use a sturdy spatula to smash each ball down firmly, pressing for about 10 seconds to create a thin patty about 5mm thick.

5. 5

   Season the smashed patties generously with salt and pepper while the first side cooks.

6. 6

   Cook for 2-3 minutes until the edges are crispy and brown. You'll see the juices pooling on top.

7. 7

   Flip the patties and immediately place a cheese slice on each. Cook for another 1-2 minutes.

8. 8

   While the cheese melts, quickly toast the buttered buns on another part of the griddle until golden.

9. 9

   Assemble the burgers: spread mayo on the bottom bun, add mustard, then the patty with melted cheese, pickles, onion, lettuce, and top bun.

10. 10

    Serve immediately while the patties are hot and the cheese is still melty.
