- 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.
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.
