Instructions
- Divide the beef mince into 4 equal loosely formed balls — don't compact them. Season generously on the outside with salt and pepper only.
- Slice the onion into thin rounds. Cook in a little oil in your skillet over medium heat for 8–10 min until golden and soft. Remove and set aside.
- Raise the heat to high until the skillet is very hot. Add the beef balls, spaced well apart. Immediately smash flat with a wide spatula pressed hard for 10 seconds — aim for thin patties.
- Cook undisturbed 2 min until a deep brown crust forms and the edges are visibly crispy. Flip, add a slice of cheddar to each, and cook 1 min more.
- Mix mayo, ketchup, and mustard together for the sauce.
- Split and lightly toast the brioche buns in the skillet. Spread the sauce on both halves.
- Layer: bottom bun, lettuce, smash patty with melted cheese, fried onions, pickles, top bun. Press and serve immediately.
Recipe notes
The key to the crust is a very hot pan and not touching the patty for the first 2 minutes.
