    Flamiche

    Published Mar 18, 2025; Modified Sep 14, 2026 by Sylvie Taylor

    Jump to Recipe Print Recipe

    This classic Leek Flamiche or Flamiche aux Poireaux comes from the Northern region of France and Belgium has creamy softened leeks and bacon. It can traditionally be made as a quiche style dish or a double crusted pie which shows in the many different recipes found online.

    How to make Flamiche

    Flamiche is one dish that has many different iterations and this is but one take from a number of different resources both linked in the recipe and omitted due to the sheer number of options that pop up when searching for a traditional take on this.

    Ingredients for Flamiche sit in a series of bowls and plates on a gray surface.

    Ingredients and substitutions for Flamiche

    • Leek: The base of this dish, this smooth allium gives a light, but full bodied flavor to the tart. If you don't love leek, you could substitute with 6 finely sliced shallots or 10 finely sliced spring onions or scallions - whilst they won't produce the exact flavor, they are cousins of the leek so will give you the most similar result here.
    • Eggs: They add structure and bind everything together so are essential in this recipe.
    • Puff pastry: Traditionally this is made with either a Pâte Brisée or shortcrust type pastry, though it can also be substituted with puff pastry as seen in this recipe. The best option is store bought to make life easier!
    • Creme Fraiche: Because this is made in a variety of ways, there are recipes that use a mixture of milk and cream or simply one of these two or creme fraiche which lends itself perfectly to this savory dish. The creme fraiche also helps set this perfectly thanks to its thicker texture.
    • Bacon: Back bacon was used as it has the most 'meat' and least fat, but you do you, use whatever bacon you want.
    • Parmesan: Salty Parmesan takes this dish to the next level, unless you are lactose intolerant, it’s best not to omit here. You could replace with Asiago or Manchego cheeses.

    See recipe card for quantities.
