Ingredients
Method
- Make pastry — pulse flour, salt, cold butter to crumbs. Add cold water until dough coheres. Wrap and chill 30 minutes.
- Preheat oven to 200°C / 180°C fan / Gas 6. Roll pastry 3mm. Line 23cm tart tin. Prick. Chill 20 minutes. Blind bake with beans 15 minutes. Remove beans — bake 8–10 minutes until pale golden and dry. Reduce oven to 180°C / 160°C fan / Gas 4.
- Cook chestnut mushrooms in half butter and oil over highest heat — 3 minutes undisturbed until golden. Stir — 2 minutes. Add remaining butter and wild mushrooms — 3–4 minutes until all golden and dry. Add garlic and thyme — 1 minute. Add sherry if using — bubble until evaporated. Season.
- Whisk eggs, cream, and milk. Add cheese, nutmeg, and seasoning.
- Spread mushrooms over pastry base. Pour custard over — to within 5mm of the top. Place on baking tray. Bake 28–32 minutes until just set with a slight wobble.
- Cool in tin 20 minutes. Serve warm.
Notes
Cook mushrooms at the highest heat in batches — caramelisation not steaming.
Mushrooms must be completely dry before going into the quiche.
Use Gruyère if possible — it pairs better with mushrooms than Cheddar.
Blind bake pastry until pale golden and completely dry.
A slight central wobble is correct — do not overbake.
Serve warm not hot for the best texture and cleanest slices.
