Tarte Flambée (Alsatian Bacon and Onion Tart)

Originally known as "Flammekueche" or "Tarte Flambée" (flame tart). In Alsace, bakers used this to test the oven temperature before baking bread: if the thin dough cooked in minutes and blistered, the oven was ready. This isn't pizza in the Italian sense: no tomato, no cheese (traditionally), just crème fraîche, onions, and bacon. Light, crispy, and smoky.

Instructions

1

Combine flour, water, oil, and salt. Knead briefly. No rising needed, just rest it for 15 mins to relax the gluten.

Tip: Resting hydrates the flour and relaxes the dough so it can be rolled paper-thin.
2

Preheat oven to max (480-500°F). Slice onions into paper-thin half-moons and cut bacon into strips.

Tip: Onion thickness is critical: they must be thin enough to soften in the short baking time.
3

Roll the dough out paper-thin (approx 2mm) on parchment paper. Spread with crème fraîche (seasoned with salt, pepper, nutmeg).

Tip: Full-fat cream won't make the dough soggy; it creates a creamy layer against the flash heat.
4

Scatter with onions and bacon. Bake for 8-10 minutes until edges are dark brown and crispy.

Tip: Don't worry if the edges char slightly; that rustic look is part of the style.
5

Serve immediately with fresh pepper.

Tip: This dish is only good fresh; as it cools, the crust loses its crunch.

Recipe FAQ

Why no yeast?
This is a quick, yeast-free version for extra crispiness (though yeasted versions exist).
Can I use red onion?
Yes, but the traditional recipe uses yellow/white onion for a sharper bite.
