Classic Quiche Lorraine

👨‍🍳 Method

For the Wrapping Dough

1. 1
   Mix the flour and salt in a bowl.

   Bowl
2. 2
   Add the cold butter in cubes and rub it in with your fingertips, until coarse crumbs form.

   💡The butter must stay cold: butter that melts in your hands gives a hard dough instead of a crumbly one. Work quickly, and if the dough warms up, put it back in the fridge.
3. 3
   Add the egg and cold water and quickly bring together with your hands, without kneading, just until the dough comes together.

   💡Knead as little as possible: long kneading develops gluten, and the dough comes out tough and shrinks in the oven.
4. 4
   Wrap in plastic wrap and chill at least 60 minutes.

   💡Chilling firms the butter and relaxes the gluten: the dough rolls out easily, doesn't stick to the counter and doesn't shrink in the oven.

For the Fried onion

1. 5
   Heat the oil in a pan over medium heat.

2. 6
   Add the onion and fry 5–8 minutes, stirring now and then, until the onion is soft and translucent and starts to turn golden at the edges. If it browns too fast, lower the heat.

   ⚙ Adding to the hot fat and fryingStove

   💡Add by cooking time: what needs long (onion, carrot, meat) goes in first, and what burns fast (garlic, dry spices) goes in last, only until fragrant.

To assemble

1. 7
   Preheat the oven to 180°C (355°F).

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 8
   Beat the eggs, cream and milk with the nutmeg, salt and black pepper.

3. 9
   Roll out the dough and line quiche pan with it. Prick the bottom of the dough with a fork.

   ⚙ Rolling Out DoughRolling pin

   💡Roll from the center outward and give the dough a quarter turn between rolls: this keeps it even in thickness and stops it sticking to the counter. If it springs back, cover for 10–15 minutes and try again.
4. 10
   Bake the crust on its own at 180°C (355°F) 15 minutes, until it is lightly golden.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
5. 11
   Scatter the cheese and onion over the crust and pour the egg mixture on top.
6. 12
   Bake at 180°C (355°F) 35–40 minutes, until the filling is set and golden.
