Leek and Stilton is one of the great British flavour combinations — the sweetness of properly softened leeks against the bold, slightly pungent, creamy character of good Stilton. In a quiche, with a rich egg and cream custard holding everything together in a crisp pastry case, it is genuinely outstanding.
This is the quiche I make for Christmas — it appears at the Boxing Day table alongside cold meats, pickles, and bread, and it disappears completely regardless of how much other food is available.
It is also the quiche for any occasion when something particularly British and particularly distinctive is wanted. The Stilton is assertive and should be — this is not a subtle quiche.
The leeks must be properly softened — the same instruction that appears throughout this site whenever leeks are involved, because it is always equally important.
Twelve minutes of gentle cooking turns leeks from slightly harsh and slightly raw to completely tender, sweet, and silky. That transformation is what gives the quiche its gentle, elegant filling to balance the bold Stilton.

- 250ml double cream
- 100ml whole milk
- 150g Stilton, crumbled — not too finely

How to Make Mary Berry Leek and Stilton Quiche
Step 1 — Make the Pastry
Pulse flour, salt, and cold butter in a food processor until fine breadcrumbs. Add cold water one tablespoon at a time until the dough just comes together. Flatten into a disc, wrap, and refrigerate for 30 minutes.
Step 2 — Line and Blind Bake
Preheat your oven to 200°C / 180°C fan / Gas 6. Roll the chilled pastry to 3mm on a lightly floured surface. Line a deep 23cm loose-bottomed tart tin. Prick the base. Refrigerate for 20 minutes.
Line with baking parchment and baking beans. Blind bake for 15 minutes. Remove beans and parchment — bake for a further 8 to 10 minutes until pale golden and completely dry. Trim the pastry edges. Reduce oven to 180°C / 160°C fan / Gas 4.
Step 3 — Cook the Leeks
Melt the butter in a large frying pan over a medium-low heat. Add the sliced leeks and cook, stirring occasionally, for twelve to fifteen minutes until completely soft, slightly collapsed, and beginning to turn sweet. Add the garlic and thyme and cook for two more minutes. Season lightly — remembering the Stilton will add significant saltiness. Remove from the heat and cool slightly.
Step 4 — Make the Custard
Whisk the eggs, double cream, and milk together until smooth. Add the nutmeg and a little white pepper. Taste before adding any salt — the Stilton in the filling will season the custard significantly during baking.
Step 5 — Assemble
Spread the softened leeks evenly over the base of the blind-baked pastry case. Scatter the crumbled Stilton over the leeks — distribute it in generous, irregular pieces rather than a fine even layer. Scatter the parsley.
Pour the egg and cream custard carefully over the leeks and Stilton — fill to within 5mm of the top of the pastry.
Step 6 — Bake
Place on a baking tray. Bake at 180°C for 30 to 35 minutes until the filling is just set with a very slight central wobble and the top is pale golden with the Stilton pieces visible on the surface.
Leave to cool in the tin for 20 minutes. Serve warm.
My Top Tips
Cook the leeks for twelve to fifteen minutes — not less. The sweet, silky quality of properly softened leeks is the counterpoint to the bold Stilton. Undercooked leeks give a slightly raw, slightly harsh edge that does not suit the gentle character of the custard filling.
Do not crumble the Stilton too finely. Larger, irregular pieces of Stilton give pools of melted cheese throughout the filling — some bites will be more strongly Stilton than others, which is pleasant and interesting. Finely crumbled Stilton distributes more evenly but gives a more uniform, slightly less dramatic flavour.
Taste the custard before adding salt. Stilton is extremely salty — one of the saltiest ingredients in British cooking. The custard for this quiche needs little or no additional salt. Always taste the custard before seasoning and add salt very cautiously if at all.
Use white pepper not black. Black pepper specks are visible in a pale, elegant custard and look slightly messy. White pepper gives clean, invisible warmth.
Blind bake the pastry until completely dry. A Stilton filling has significant salt and moisture. The pastry must be completely dry and golden before any filling goes in — even slightly underdone pastry will be soggy in the finished quiche.
Serving Suggestions
At room temperature as part of a Christmas or Boxing Day spread — alongside cold meats, chutneys, and good bread. Warm as a lunch with a simple watercress salad dressed with walnut oil and lemon. Cold the next day — leek and Stilton quiche is outstanding cold.

Notes
Frequently Asked Questions
Can I use Gorgonzola or Roquefort instead of Stilton?
Yes — both give a similarly bold, blue cheese character. Gorgonzola is slightly creamier. Roquefort is slightly sharper. Both work beautifully with the sweet leeks.
Can I use a milder cheese if Stilton is too strong?
Yes — mature Cheddar gives a more familiar, less assertive result. The combination of leek and Cheddar is very good — simply different in character. Gruyère gives a nutty, more French character.
Can I add walnuts?
Yes — 50g of roughly chopped walnuts scattered over the leeks before the Stilton give a pleasant crunch and a slight bitterness that suits the Stilton pairing beautifully. Leek, Stilton, and walnut is a classic trio.
Can I make the pastry case the day before?
Yes — blind bake the pastry case and store it at room temperature overnight. Add the filling and bake on the day of serving. This is the ideal approach for stress-free entertaining.
