Preparation

1

Peel and chop onions. Melt butter in a frying pan, add onions and sauté for a few minutes. Season with salt and pepper. When they start to turn golden, sprinkle with sugar and continue cooking, stirring regularly. When caramelized, keep warm.

Prepare the aioli sauce: place an egg yolk in a bowl and add the mustard. Season with salt and pepper. Whisk briskly, then drizzle in the oil while continuing to whisk the mixture. 

3

Peel and mince garlic, add to sauce and mix. 

4

Cut buns in half. Set aside.

5

Heat a frying pan with half the butter and cook the meat. Season with salt and pepper. 

6

Add cheese to each ground steak and cover with a lid. 

7

In another pan, heat remaining butter and lightly brown buns.  

8

Spoon a little sauce over each bun base, then place a steak on top. Cover with caramelized onions and add the salad. Place the other half of the bun on top and add a spade. Serve immediately.
