How to prepare a flakey Keto-friendly pie dough?

The crust starts with 2 Keto-friendly flours: almond flour and coconut flour. They are mixed with psyllium husk powder and xanthan gum, which prevent the crust from falling apart. Cold butter is then incorporated into the dry ingredients. Using cold butter is crucial for a flakey crust. Using room temperature or melted butter will yield a hard crust. Finally, an egg is added to form a dough. You can use this low-carb crust in many Keto recipes, including sweet ones. To prepare a sweet pie crust, simply mix a couple of tablespoons of powdered sweetener with the dry ingredients.

What type of cheese is used in this Keto quiche Lorraine?

Traditionally, quiche Lorraine is made with Gruyere cheese, and just like many French Keto recipes, it is best to keep it authentic. However, if you don’t have Gruyere or don’t mind switching things up, you can use parmesan, mozzarella, white cheddar, or provolone.
