Ingredients
For the shortcrust pastry
- 175g plain flour
- 75g cold unsalted butter, cut into cubes
- 2 to 3 tablespoons cold water
For the mushroom filling
- 200g chestnut mushrooms, thinly sliced
- 1 tablespoon butter
- 3 large eggs
- 200ml double cream
- 50g mature cheddar cheese, grated
- Salt, to taste

How to Make Delia Smith Mushroom Quiche Recipe
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the quiche cooks evenly.
- Make the pastry: Rub the butter into the flour until it looks like fine breadcrumbs. Add cold water a little at a time and bring together into a dough.
- Line the tin: Roll out the pastry and line a greased 23cm tart tin. Chill for 15 minutes, then line with parchment and baking beans.
- Blind bake: Bake the pastry case for 15 minutes. Remove the beans and parchment, then return to the oven for 5 minutes until lightly golden.
- Cook the mushrooms: Melt butter in a pan and cook the mushrooms over medium heat until soft and any moisture has evaporated.
- Prepare the filling: Whisk the eggs and cream together in a bowl. Season well with salt and pepper.
- Assemble: Spread the mushrooms over the pastry base, sprinkle with cheese, then pour over the egg mixture.
- Bake: Bake for 30 minutes until just set with a slight wobble in the centre.
- Cool and serve: Leave to cool slightly before slicing. Serve warm or cold.
