freezer-friendly, make ahead, oven, stove top

1 9" deep dish pie crust (for a single crust pie, homemade or store-bought (refrigerated or frozen))
6 slices bacon (cut into lardons (or 1/4" matchsticks) (I prefer a low-sodium variety))
2 leeks ((white + a bit of the light green part) cleaned + sliced into half moons)
2 cloves garlic (minced)
2 ounce gruyere cheese (shredded)
1 ounce grated parmesan (divided)
4 large eggs
1½ cups low fat buttermilk
2 tablespoon chives or thyme (chopped (or a combo))
kosher salt + fresh cracked black pepper

Preheat oven to 450°F.
For homemade/refrigerated pie dough: Transfer the crust to a pie plate and crimp the edges. Chill in the fridge for 20 to 30 minutes.For frozen pie crust: Remove from the freezer to counter for 10 minutes.
Prick the bottom and sides of the pie crust with a fork, then bake for 10 to 12 minutes. Keep and eye on it; prick any areas that start to puff up.
Remove from the oven; reduce the oven temperature to 325°F.
Add bacon pieces to a cold skillet and place over medium heat. Cook the bacon until crisp, then transfer to a paper towel to drain. Remove all but 1 tbsp of the rendered fat. Add the leeks and garlic and cook until the leeks are tender, only about 2 to 3 minutes. Drain the leeks on a paper towel as well. Distribute the bacon and leeks across the bottom of the precooked pie shell. Sprinkle with gruyere and half the parmesan.
Whisk the eggs, buttermilk and herbs together in a mixing bowl. Season with kosher salt and fresh cracked black pepper. Pour the mixture over the filling. Sprinkle the top with remaining parmesan.
Bake for 45 to 50 minutes or until a knife inserted into the center comes out clean. Rest for 10 minutes before slicing.

You can use broccoli and stilton cheese instead of bacon and leek as a meat free option
