Start by making the crust: mix flour, sugar and salt. Then add the diced butter and mix until the butter pieces are quite small. Then start by adding a bit of water, then work the dough. Keep adding the water until the dough is soft and smooth.

Transfer dough to a lightly floured work surface to roll it out; transfer to a pie dish. Gently press the dough into the pie dish and trim excess dough around the edges. Put the crust in the fridge

Dice the onion, chop the asparagus (after removing the end). Cook the onion in a pan with a bit of olive oil until tender, then add the asparagus. Cook for a few minutes, until tender and crispy

Make the custard by whisking the eggs,the milk, salt and pepper

Remove the crust from the fridge, add the onion and the asparagus, crumble the goat cheese and then add the custard

Bake in a preheated oven at 190°C for 35/45 min. Let it stand for 5 min before serving
