🧅 What is Tarte aux Poireaux?

Tarte aux poireaux is a traditional French savoury tart made with leeks sautéed in butter, often mixed with cream, eggs, and cheese, then baked in a shortcrust or puff pastry base. It's similar to a quiche but with a more prominent leek flavour.

This dish is popular across France, especially in the north and Alsace-Lorraine regions. It's enjoyed warm or cold, making it an ideal choice for lunchboxes, brunch, or a light supper with a salad.

👩‍🍳 How to Make Tarte aux Poireaux – Step-by-Step

1. Prepare the Pastry (Skip if using pre-made)

Place the flour and salt in a bowl. Rub in the butter until the mixture resembles breadcrumbs. Add the egg yolk and enough cold water to bring it together into a smooth dough. Wrap and chill for 30 minutes.

Roll out the pastry and line a 23cm tart tin. Trim the edges and chill again for 15 minutes. Prick the base with a fork, line with baking paper and baking beans, and blind bake at 180°C (fan 160°C) for 15 minutes. Remove the paper and beans, and bake for another 5 minutes until golden.

2. Cook the Leeks

Melt the butter in a frying pan over medium heat. Add the sliced leeks and cook gently for about 10–12 minutes, until soft and sweet but not browned. Season with salt, pepper, and a pinch of nutmeg if using. Set aside to cool slightly.

3. Make the Filling

In a bowl, whisk together the eggs, cream, and milk. Stir in the cooled leeks and grated cheese (if using). Adjust seasoning to taste.

4. Assemble and Bake

Pour the filling into the baked pastry case. Smooth the top and sprinkle extra cheese if desired. Bake in a preheated oven at 180°C (fan 160°C) for 30–35 minutes, or until the tart is set and lightly golden on top.

Let it rest for 5–10 minutes before slicing.

🧑‍🍳 Tips for Success

Don’t skip blind baking the pastry—it ensures a crisp, non-soggy base.
