Prepare the Dough: In a large mixing bowl, combine the all-purpose flour and salt. Add water and olive oil to the dry ingredients. Mix until a rough dough forms, then knead on a floured surface for about 5 minutes until smooth.
2 cups all-purpose flour, ½ cup water, 1 tsp salt, 2 tbsp olive oil
Preheat the Oven: Preheat your oven to 500°F (260°C). Place a baking sheet or pizza stone inside to heat up.
Roll Out the Dough: Divide the dough into two equal portions. Roll each portion out on a floured surface until paper-thin. Transfer the rolled-out dough onto parchment paper for easy handling.
Assemble the Flammkuchen: Spread half of the crème fraîche evenly over each dough base. Sprinkle with a pinch of nutmeg and freshly ground black pepper. Distribute the sliced onions and bacon evenly over the two flatbreads.
1 cup crème fraîche, 1 medium onion, Pinch of nutmeg, Freshly ground black pepper, 4 oz bacon
Bake: Carefully slide the parchment paper with the assembled Flammkuchen onto the preheated baking sheet or pizza stone. Bake for 10-15 minutes, or until the edges are golden brown and crispy.
Serve: Remove from the oven, slice, and serve hot. Prost!
