In the bowl of a stand mixer fitted with the paddle attachment, combine flour, salt, olive oil, and water. Mix until a smooth dough comes together.
2 cups all-purpose flour, ¼ teaspoon salt, 2 tablespoons olive oil, ½ cup water
Coat the dough with some olive oil and cover with plastic wrap. Let rest at room temperature for about 30 minutes while you preheat the oven.
Preheat the oven to 480 degrees F (250 C).
Thinly roll out the dough and transfer it to a parchment paper-lined baking sheet.
Combine crème fraîche with salt, pepper, and nutmeg. Spread over the rolled-out dough. Sprinkle bacon cubes and onion evenly over the dough.
¾ cup crème fraîche, ½ teaspoon salt, ¼ teaspoon pepper, 1 pinch nutmeg, ⅔ cup bacon matchsticks, 1 medium onion
Bake in the middle of the oven for 10-15 minutes or until the crust is golden brown and the bacon cooked.
