Flammkuchen (French – German Pizza)

When most people think pizza, they think Italy, but Flammkuchen (also called Flammekueche or tarte flambé in French), the crispy and smoky pizza from the France / Germany border, is definitely worth your time!

Bacon, caramelized onions, and a creamy base make up this classic German pizza, Flammkuchen, all on top of a cracker-thin, crispy crust.

We do love a big slice of saucy, mozzarella-laden, classic, Italian pizza. But, it’s also fun to explore the way that pizza has taken on a life of its own in regions outside of Italy.

Like this specialty of Alsace, France and southwestern Germany: Flammkuchen (sometimes spelled Flammenkuchen in German and known as Flammekueche or tarte flambé in Alsace, France).

What is Flammkuchen?

Translated ‘flame cake,’ flammkuchen really aren’t pizza at all, in their own right. They were originally used by bakers to test the temperature of their ovens. A bit of dough was taken and rolled flat, topped with crème fraîche, and baked in the wood-fired bread oven for a few minutes.

The amount of time it took for the flammkuchen to bake to nearly-blistered crispness told them the oven’s temperature. If the flammkuchen came out just right, then the ovens were ready to bake their bread!

This baker’s oven test became a hit, and now can be found made with numerous toppings of its own!

Is Flammkuchen French or German? 

Flammkuchen (pronounced flam-KOOK-en) in German, or Flammekueche (pronounced flam-KOOCHE) or tarte flambé in French, comes from the Alsace region of France (just across Germany’s the southwestern border with France).

The Alsace region, while currently a part of France, has bounced back and forth under German and French control through the centuries. So, understandably, there is a lot of German influence in this region, and a lot of Alsatian, French influence on the German side across the border. 

You will find this specialty on both sides of the current border. It is thought that it originated as Flammekueche (tarte flambé) with bakers in Alsace. (But, when it originated, and whether Alsace was a part of France or Germany at that time, is up for debate.)

Crispy Thin Crust Pizza

Thin and crispy crust pizza lovers, this pizza is for you!

Flammkuchen is characterized by its incredibly thin, crisp, and blistered crust.

We’re talking cracker-like here folks.

What Is Crème Fraîche?

Rather than a tomato sauce, the dough for flammkuchen is spread with crème fraîche (KREHM fresh), a thick, French, soured cream.

Crème fraîche is less sour than American sour cream, so if you can’t find crème fraîche, we recommend using plain, strained yogurt. (Yogurt is naturally thinner than crème fraîche, so we strain it through a fine mesh sieve or cheesecloth to thicken it to a more proper consistency.)

When the crème bakes with the crust, it creates a slightly tart, creamy contrast to the crust’s crispness.

Bacon and Caramelized Onion German Pizza

While you can use any toppings that you like for you flammkuchen, the most traditional combination includes bacon and caramelized onions. These are seasoned only with a bit of nutmeg and black pepper.

Other common variations include

  • gruyère (or Swiss) cheese
  • mushrooms
  • Munster cheese

You can even find sweet versions of flammkuchen that are typically made with apples, cinnamon, and a sweet liqueur.

We went for the classic caramelized onion and bacon version today. Because, really, how can you go wrong with those toppings?

Crisp, creamy, smoky, with a hind of caramelized sweetness.

This pizza makes for a perfect light dinner or appetizer.

Our Flammkuchen Recipe

As far as making pizza goes, this flammkuchen recipe is fairly straightforward.

The dough is a simple mixture of flour, salt, water, and oil that mixes together well and kneads nice and smooth. (Kneading to a smooth dough is important because you want your dough to be able to stretch out nice and thin.)

While the dough rests, it’s time to prepare the toppings. 

  • Mix the crème fraîche and nutmeg for your ‘sauce’.
  • Saute up some bacon. 
  • Caramelize some onions in the bacon grease. 

Then, it’s time to stretch the dough. We like to stretch it right onto a baking sheet, that way once it is stretched, we don’t have to move it and risk tearing the dough.

Finally top and bake ’till crispy!

How many days can you leave the dough in the refrigerator before using?

Hi Jackie. You could refrigerate the dough for a day or two before using, if necessary.

Hi, I’m Wondering if this could be made a day or 2 ahead and reheated? Want to make for our families German day party! Thanks In advance, Can’t wait to try!

Hi Dawne. In our experience, flammkuchen leftovers do reheat fairly well in a toaster oven. But, it's still not quite as good as fresh from the oven. (You just can't quite get that fresh from the oven crisp while maintaining the creaminess of the crème fraîche when re-heating.) You could make your dough ahead of time, and keep it wrapped in plastic or in an air-tight container in the refrigerator until a few hours before you are ready to use it. You could also, pre-cook the bacon and the onions and mix your crème fraîche mixture all ahead of time. That way you would just need to roll out your dough, top, and bake before serving. And, you would still be enjoying it fresh and crispy from the oven.

For a suggestion...saute the leaves if Swiss Chard, add to the bacon and onions. Top with the Swiss Cheese. Also, use the Roggenbrot recipe for the crust....
