From my Buttermilk Pie Crust to the hearty egg custard, you'll learn how to make quiche perfectly with all the fillings you love!
Preheat the oven to 350°F (180°C) and line a 9-inch (23 cm) deep dish pie pan with the buttermilk pie crust.
Line the crust with parchment paper, fill it with pie weights (rice, beans, etc.), and bake for 15-20 minutes.
Remove the paper and weights and continue baking for 5-10 more minutes until the bottom of the crust looks dry and just beginning to show a bit of color. Remove from the oven and lower the heat to 325°F (165°C). Set the crust aside while you prepare the filling.
In a large bowl, whisk together the eggs, cream, milk, salt, and pepper until smooth. Lastly, stir in your choice of cheese, protein, and vegetables.
Pour the filling into the crust and bake for 45-60 minutes, until the filling is slightly puffed and set in the middle. It will spring back slightly when done and feel firm under your finger.
Let cool down for 30 minutes before serving. This is best the day it is made, but you can store leftovers, loosely covered, in the refrigerator for up to 3 days.
