❤️About This Recipe
Gruyère is a hard yellow cheese, sweet but slightly salty, with a flavor that varies widely with age. It is often described as creamy and nutty when young, becoming more assertive, earthy, and complex with age.
When fully aged (which can take up to a year) it tends to have small cracks which impart a slightly grainy texture. It is traditionally used in French onion soup, and Croque-monsieur, but in a quiche such as this it introduces a savoriness without dominating the other ingredients.
Where Does Gruyère Cheese Originate?
Gruyère is named after the town of Gruyères in Switzerland, and originated in the cantons of Fribourg, Vaud, Neuchâtel, Jura, and Berne.
Before 2001, when Gruyère gained Appellation d'Origine Contrôlée (AOC) status as Swiss cheese, some controversy existed about whether French cheeses of a similar nature could also be labeled Gruyère (French Gruyère style cheeses including Comté and Beaufort, so if you want to be purist then substitute one of those).
📝Ingredient List
- shortcrust pastry (store bought or use my Pate Brisée Recipe)
- leeks
- butter
- crème fraiche, sour cream, or heavy cream
- milk
- eggs
- Gruyère cheese
🔢Instructions
- Roll out the pastry on a floured surface to about 3mm/1/8in. thickness, and use it to line a 23cm/9in. flan case, ensuring that the lining comes up above the top of the case (do not trim it).
- Line with foil and then rice, pasta, or ceramic beans, and bake blind for 10 minutes.
- Remove the foil and its contents, and bake for a further 4 minutes.
- Meanwhile, cut the leeks into approximately ½cm/1/4in. slices.
- Melt butter in a pan, add the leeks, and stir to coat.
- Cover and cook over on low heat for 8 minutes.
- Uncover and cook for a further 4-5 minutes.
- Lightly beat the crème fraiche, milk, and eggs. Stir in the leeks and most of the cheese, and season well.
- Pour into the flan case.
- Sprinkle with the rest of the cheese and bake for 25 minutes, or until set. (A knife blade when inserted into the flan filling, careful not to pierce the crust, will come out clean when cooked.)

❄️Storage
- A cooked and cooled flan can be covered with clear wrap and kept in the fridge for up to 3 days.
- A flan "well wrapped" can be frozen for up to 4 months, but it may not be the same consistency when thawed as before frozen and the crust may be soggy.
Top Tip
Cook the flan at a low, even temperature to prevent lumping and no peaking while cooking which cools down the oven.
