Preheat your oven to 375°F (190°C) to ensure even baking.
If using a homemade crust, prepare it according to the recipe. If using a store-bought crust, place it into your pie dish and press it firmly against the sides.
In a mixing bowl, whisk together the eggs, whole milk, heavy cream, salt, and pepper until well combined.
Stir in your choice of shredded cheese and any cooked vegetables, meats, or herbs you’d like to include.
Carefully pour the egg mixture into the prepared pie crust, making sure the fillings are evenly distributed.
Place the quiche in the preheated oven and bake for 35-45 minutes, until the top is golden and the center is set.
Allow the quiche to cool for about 10 minutes before slicing.
