Method

Restated from the original video

1. 1

   Melt 20 g (3/4 oz) of the butter in a large skillet over medium-low heat. Add the onion and a pinch of salt.

2. 2

   Cook the onion, stirring now and then, until soft and deep golden, 20-25 min. Move it to a plate.

3. 3

   Divide the beef into 2 portions. Shape each into an oval patty a little larger than a slice of bread and about 1 cm (1/2 in) thick. Season both sides with the salt and pepper.

4. 4

   Wipe out the skillet and heat it over medium-high. Cook the patties 3-4 min per side, until browned and cooked through, 71 °C (160 °F) inside. Move them to a plate.

5. 5

   Spread the softened butter on one side of each bread slice. Set 2 slices butter side down on a board.

6. 6

   Layer each with a slice of Swiss, a patty, half of the onion and a second slice of Swiss. Close with the remaining bread, butter side up.

7. 7

   Wipe out the skillet again and set it over medium heat. Cook the sandwiches 3-4 min per side, pressing lightly, until the bread is golden and the cheese has melted.

8. 8

   Rest for 1 min, then cut in half on the diagonal.
