Crispy Smash Burgers

• 300g beef mince (20% fat)
• 2 brioche buns
• 2 slices cheddar
• 1 onion
• Lettuce
• 2 tbsp mayo
• 1 tbsp ketchup
• 1 tsp mustard
• Pickles

1. 1

   Divide the beef mince into 4 equal loosely formed balls — don't compact them. Season generously on the outside with salt and pepper only.

2. 2

   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.

3. 3

   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.

4. 4

   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.

5. 5

   Mix mayo, ketchup, and mustard together for the sauce.

6. 6

   Split and lightly toast the brioche buns in the skillet. Spread the sauce on both halves.

7. 7

   Layer: bottom bun, lettuce, smash patty with melted cheese, fried onions, pickles, top bun. Press and serve immediately.
