👨‍🍳 作り方

1. 1

   For the dough: Combine flour and salt in a bowl. Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Gradually add cold water, mixing until the dough just comes together.

   💡 プロのコツ: Do not overwork the dough.
2. 2

   Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.

   ⏱️ 30 minutes
3. 3

   While the dough chills, prepare the filling. If using bacon, cook it in a skillet until crisp. Remove bacon and set aside, leaving the rendered fat in the skillet.

4. 4

   Add the sliced onions to the skillet with the bacon fat (or butter/oil) and sauté over medium-low heat until very soft and golden brown, about 15-20 minutes.

   ⏱️ 15-20 minutes

   💡 プロのコツ: Slowly sautéing the onions brings out their sweetness.
5. 5

   In a separate bowl, whisk together the eggs, cream (or milk), salt, pepper, nutmeg, and half of the grated cheese.

6. 6

   Preheat your oven to 200°C (400°F). Roll out the chilled dough on a lightly floured surface into a large circle or rectangle, about 0.5 cm thick. Transfer to a baking sheet lined with parchment paper.

   💡 プロのコツ: You can also press the dough directly into a tart pan.
7. 7

   Spread the sautéed onions evenly over the dough, leaving a small border. Sprinkle the cooked bacon (if using) and the remaining grated cheese over the onions.

8. 8

   Pour the egg and cheese mixture evenly over the toppings. Bake for 30-35 minutes, or until the crust is golden brown and the filling is set and lightly golden.

   ⏱️ 30-35 minutes

   💡 プロのコツ: The filling should not be jiggly when done.
