for the dough:

  • 2 cups flour 250g
  • 1/2 cup very warm water 120g
  • 2 tablespoons olive oil
  • 1/2 teaspoon fine sea salt

for the topping:

  • 1/2 cup creme fraiche 150g
  • 7 oz thick-cut bacon or Speck 200g
  • 1 small/medium onion
  • chives optional


Make the dough:

  • Preheat the oven to its highest setting (about 500°F/250°C).
  • In a medium/large mixing bowl stir the flour with salt.
  • Add the olive oil and very warm water (from the tap). Stir with a wooden spoon until roughly combined.
  • Knead the dough by hand or with a stand mixer fitted with a dough hook attachment for a couple of minutes until the dough is soft and smooth.
  • Wrap the dough in plastic foil and set aside to rest for 20-30 minutes.

Assemble the tart:

  • Prepare the ingredients: cut bacon into small cubes. Cut onions into thin slices and sprinkle them with a pinch of salt. Add the creme fraiche into a small bowl, season it with salt and pepper, stir until combined.
  • Roll out the dough very thinly into an oval or rectangle shape and place it on a baking sheet.
  • Spread the creme fraiche over the dough leaving some border, top with bacon and onion slices (if they released some water, squeeze it out).
  • Bake the tart for about 10-12 minutes or until golden brown. The baking time may be longer (up to 15-18 minutes) if your oven was not as hot as mine.
  • Sprinkle with thinly sliced chives (optional).
  • Cut into squares and enjoy!


  • You can use regular bacon, thick-cut bacon, or German Speck (not an Italian type of Speck) for this recipe.
  • You can substitute creme fraiche with Greek yogurt or sour cream mixed with 1-2 Tbsp of olive oil.
  • You can cook your bacon and onions before putting them on your flatbread but traditionally they are used raw (I prefer them both raw).
  • Storage: Store this tart in the fridge, wrapped in plastic foil, for up to 2 days. Reheat in the oven until crispy. It tastes best freshly made but it's also pretty good reheated.
  • Don't load your Flammkuchen with too many toppings - it will be soggy and not crispy.
  • If you have a pizza stone use it to get an even crispier result.
  • Calories = 1 serving (1/6 of the recipe). This is only an estimate!
