👨🍳 Instructions
- 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.
💡 Tip: Do not overwork the dough. - 2
Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
⏱️ 30 minutes - 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.

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💡 Tip: Slowly sautéing the onions brings out their sweetness. - 5
In a separate bowl, whisk together the eggs, cream (or milk), salt, pepper, nutmeg, and half of the grated cheese.

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.
💡 Tip: You can also press the dough directly into a tart pan. - 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.

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💡 Tip: The filling should not be jiggly when done. - 9
Let the Tierli Fladen cool slightly before slicing and serving.
