Recipe: Onion Tart

The day before:

1- In a pot, melt the butter then add the sliced onions. Salt, pepper, add a grating of nutmeg and let sweat covered very gently without browning for 10 minutes.

2- Then pour in the beer, adjust the seasoning and let "stew" for an hour covered gently.
If there is still liquid, continue cooking a little until it evaporates.

3- Transfer to a bowl and let cool in the open air.
The next day

4- Preheat the oven to 200°c (th6).
Roll out your pastry base then fill with the onion puree.

5- In a bowl, break the eggs, add the cream, season and give a quick blend (5 seconds) then pour this mixture over your onions and bake for 30 minutes at medium heat in the oven.
Serve this magnificent onion tart with a nice salad such as chicory or small endives for example.
