French Pastry Recipe: Onion Tart (Tarte à L’oignon)
For the pastry:
2 cups flour
70g cold unsalted butter, cut into small pieces
½ teaspoon salt
1 egg, lightly beaten
For the filling:
3-4 medium sweet white onions, sliced finely
100g grated cheese (ideally Gruyère)
50g unsalted butter
2 tbsp flour
1 tbspn dijon mustard
1 tsp sugar
2 egg yolks
150ml creme fraiche/light sour cream
pinch salt and pepper
Mix flour, salt and butter until it forms the consistency of breadcrumbs. Add the egg and just enough water to form a dough.
Wrap in clingfilm and put in the fridge for 30 minutes.
Preheat oven to 180C.
Cook the onions and bacon gently in the butter, sugar, and salt. Make sure the onions don’t brown – they should just soften. You will need to keep an eye on it and stir. Add the flour, continue to cook for one minute, then remove from heat. Add the rest of the filling ingredients.
Then, take the pastry out of the fridge, and roll out on a floured surface. Place the pastry in a springform tart tin, prick with a fork and chill in the fridge for around 20 minutes. Then take out from the fridge, line pastry case with greaseproof paper, add beans or rice to weigh down and bake in the oven for 10 minutes.
Take the pastry shell out of the oven and remove the paper and beans. Spoon filling into the pastry shell.
Turn the oven up to 190C and bake for approximately 30-40 minutes.
