Flammkuchen is a traditional dish from the Alsace. If you do not now the Alsace, it’s located on France’s eastern border and the west bank of the upper Rhine adjacent to Germany and Switzerland. Everybody there eats flammkuchen (and a lot of it).
If you do not know it, it’s almost like a pizza. But the dough is thinner, and it’s typically spread with creme fraiche, loads of onions and bacon. This recipe for the vegetarian flammkuchen is made with creme fraiche and onions too, but instead of the bacon, you have to add some king oyster mushrooms and tomatoes. If you don’t like the king oyster mushrooms, just swap them with champignons.
Vegetarian Flammkuchen – Don’t forget to sprinkle the onions over the creme fraiche like I did…
And do not forget to sprinkle the onions over the creme fraiche as I did 🙂 It will get a bit messy if you have to sneak them under the king oyster mushrooms afterward….
