How to prepare the puff pastry with potatoes, onions, and bacon
To prepare the puff pastry with potatoes, onions, and bacon, start by peeling the potatoes, then cut them into slices a few mm thick (1). Peel the onion and cut it into slices of the same thickness (2).
With your hands, separate the onion rings. In a non-stick frying pan, pour 2 tablespoons of oil (3) and heat it well.
Then add the potatoes (4) and cook them over low heat for 7-8 minutes, turning them often, until they are slightly golden (5).
Lightly salt them and drain with a slotted spoon. Let them dry on a sheet of paper towel. In the same pan, add another tablespoon of oil, heat it well, and add the onions (6).
Let the onions sauté over low heat for a couple of minutes, then drizzle them with a cup of hot water (7), lightly salt them and let them stew for 7-8 minutes. When they are soft and slightly caramelized (8), drain and set aside.
Remove any remaining water from the pan and return it to the heat. When it is hot, add the diced bacon and let it fry over high heat for about 5 minutes (9). Drain it and let it dry on a sheet of paper towel.
In a bowl, crack the eggs and add a pinch of salt and a pinch of pepper (10). Beat them briefly with a fork or a hand whisk, then also add the milk (or cream), the parmesan, and the chopped parsley (11). Beat again for a few seconds to mix well (12).
Unroll the puff pastry and, keeping the parchment paper on which it is packaged below, place it in a 9.5-inch diameter pan, making sure it adheres well to the bottom and sides. Then prick it with the tines of a fork (13).
Now arrange first the potatoes, forming a layer that covers the bottom of the puff pastry (14). Then layer the onions on top (15).
Then add the bacon, distributing it evenly (16). Pour the beaten eggs over the top, making sure they cover all the ingredients.
Fold the edges of the puff pastry inward to form a crust (17). Bake the savory pie with potatoes, onions, and bacon in a preheated oven at 356°F (static) for about 40 minutes, until the puff pastry is puffed and golden (18).
Take it out of the oven and let it cool for at least 5 minutes before removing it from the pan. The puff pastry with potatoes, onions, and bacon is great served hot or at room temperature.
Storage
You can store the savory pie in the refrigerator for a couple of days and then briefly reheat it in the oven or microwave before serving.
Tips and Variations
If you do not like puff pastry, you can replace it with a roll of shortcrust pastry. Instead of onion, for a more delicate taste, you can use scallions or half a leek. Depending on your taste, you can use sweet or smoked bacon or, as an alternative, speck.
