Tarte Flambée or Flammekueche, is a traditional dish from Alsace, similar to a thin-crust pizza topped with crème fraîche, onions, and lardons or bacon. If you're dining in Alsace, the dough may be cracker-crisp and made with no yeast. Sadie, however, enjoys a puffier pizza-style crust. She also can't resist adding cheese. It's also yummy without the meat for a vegetarian version.
In a largish bowl, mix the flour and salt. Dissolve the yeast and sugar in warm water an let sit for a few minutes until bubbly.
Add the yeast mixture and the olive oil to the dry ingredients. Mix until a dough forms.
Knead the dough on a floured surface for about 7 to 10 minutes, until smooth and elastic. You can also knead in a food processor or mixer, according to their dough instructions.
Place the dough in a lightly oiled bowl, cover with a damp cloth or plastic wrap, and let rise in a warm spot until doubled. A microwave with a mug of steaming hot water inside makes a great proofing box.
Slice the onion as thinly as possible.
In a skillet, cook the lardons or bacon until crispy. Drain on paper towels
Add the crème fraîche to a mixing bowl. Season with salt, pepper, and a pinch of nutmeg, if desired.
Stir in the onions.
Preheat your oven to its highest setting (around 500 degrees (F) if possible). If you have a pizza stone, place it in the oven to heat up for at least half an hour.
Stretch the dough very thinly on a floured surface. Transfer the dough to a pizza peel (if using a pizza stone) or to your pizza pan.
Spread the crème fraîche and onion mixture evenly over the dough, leaving a small border around the edges.
Scatter the cooked lardons or bacon on top. Add cheese if using.
Bake in the preheated oven for 10 to 15 minutes, or until the crust is golden and crispy and the onions and cheese are lightly browned.
If using a pizza stone, your Tarte Flambée may cook faster, so keep an eye on it.
Remove from the oven, garnish with herbs if desired, and serve immediately. Bon appétit!
If you can't find crème fraîche, sour cream (regular or full-fat) will work in a pinch. With a bit of googling, you could also experiment with making your own crème fraîche with the simple ingredients of cream, buttermilk and time.
