In a bowl, stir together your flour and salt. Using two butter knives, held against each other with one in each hand to form an “X,” cut your butter into your dough, with the knives pulling away from each other and back in, until you have a sand-like consistency.
Add in your water (I like to put a few ice cubes in a glass before filling it with cold water to make sure it’s extra cold), stir together, and then compress the dough into a ball. See notes below if you have a food processor!
Place your dough between two large pieces of parchment paper, and roll to ⅛” thickness - making sure your dough is an even thickness throughout.
Gently peel the parchment back from the top layer, lay it back onto the dough, flip all of it over, and repeat with the bottom (now top) layer of parchment.
Removing one side of the parchment, carefully lay that side face down into a 9-inch pie dish and remove the top layer of parchment
Carefully shift the dough to ensure it is lying flat within the pan and along the sides. If you have more than an inch excess, use a butter knife to cut away an extra and save for later.
Tuck under the remaining excess dough around the edges, to form your crust
Make a peace sign with your pointer and middle fingers on one hand, and place it along the edge of your crust. With the pointer finger of your other hand, pointing toward the center of the peace sign, pull back the dough in the center of your fingers. This will form a crimp. Repeat along the edge of your crust until complete.
Place your pie dish with the crimped crust in the fridge for 15 minutes.
Preheat your oven to 425F
Once chilled, remove your pie dish from the fridge and prick the bottom and sides of your crust with a fork to prevent the crust from puffing when you bake. Crinkle a piece of parchment paper and lay it carefully in your dish before pouring in your baking weights.
Bake your chilled crust for 10 minutes, remove from the oven, and carefully remove the parchment paper and baking weights before returning to the oven to bake an additional 6 minutes, until the inside bottom of your crust is no longer wet looking. Cool completely before adding your filling
Preheat your oven to 350F
In a bowl, whisk together your eggs, milk, yogurt, salt, and pepper. Stir in your three cheeses
Pour the mixture into your blind-baked pie crust and smooth out as needed
Bake for 40-45 minutes, until puffed and lightly browned in spots
Allow to cool for 15 minutes before slicing
Enjoy!
