In a mixing bowl, whisk together the flour and salt. Cut in the cold butter with a pastry cutter or your hands until the mixture resembles coarse crumbs. Gradually add ice water, one tablespoon at a time, until the dough comes together. Shape into a disc, wrap in plastic, and refrigerate for 30 minutes.
Roll and Blind Bake
Preheat your oven to 375°F (190°C). Roll out the dough on a floured surface to fit a 9-inch pie pan. Press it into the pan, trimming excess dough. Prick the bottom with a fork, line with parchment paper, and fill with baking weights. Bake for 15 minutes, remove the weights, and bake for another 5 minutes. Let cool slightly.
Make the Filling
In a bowl, whisk together eggs, milk, cream, salt, pepper, and nutmeg. Stir in shredded cheese and any additional fillings like bacon or vegetables.
Assemble and Bake
Pour the filling into the pre-baked crust and bake for 35-40 minutes, or until the center is just set. Let the quiche cool for 10 minutes before slicing.
Serve and Enjoy
Serve warm or at room temperature with a simple side salad for a perfect meal.
