Parmesan & Leek Quiche

A variation on the classic French cheese quiche, this Parmesan and leek quiche is rich and flavorful.
When I was studying abroad in France, every day for lunch I would walk to the pastry shop near my university and treat myself to an individual quiche fromage — a delicious little habit that quickly cost me all my skinny jeans. Over 20 years later, it is still one of my favorite things to eat. This parmesan and leek quiche is a wonderful variation on the classic French cheese quiche; the leeks impart a mellow, almost sweet onion flavor while Parmesan cheese makes the custard filling extra flavorful.
What You’ll Need To Make Parmesan & Leek Quiche
I use a good-quality store-bought crust to save time but feel free to make your own if you prefer. The secret to success, whether you make the crust yourself or use pre-made, is to pre-bake it so it won’t be soggy.
For the cheese, it’s important to use authentic Parmigiano Reggiano cheese for this recipe. You can always tell if it’s authentic by looking at the rind, which is embossed with the name over and over. If the cheese is already grated, it should be labeled “Parmigiano Reggiano,” not “Parmesan.”
Leeks are part of the onion family, but they have a milder flavor. They’re notoriously sandy and dirty (and very good at hiding it) so it’s important to wash them well. To clean them, cut off and discard the root ends and thick dark green parts, then cut the leeks in half lengthwise. Rinse each half under cold water, pulling apart the layers to remove any grit that’s tucked inside.
How To Make Parmesan & Leek Quiche
To begin, preheat the oven to 400°F. Remove the pie shell from the freezer and thaw it until just soft enough to easily prick with a fork (10 to 20 minutes). Prick the bottom and sides all over with a fork and bake on the center rack until lightly golden, 10 to 15 minutes. Turn the oven down to 325°F.
While the crust bakes, melt the butter in small sauté pan over medium-low heat. Add the leeks and season with a bit of salt and pepper.
Cook over medium-low heat, stirring occasionally, until very soft, about 15 minutes. Do not brown. Taste and adjust seasoning (they should be well-seasoned). Set aside to cool.
In a medium bowl, combine the heavy cream, eggs, thyme, nutmeg, Parmigiano Reggiano cheese, 1/4 teaspoon salt and 1/4 teaspoon pepper.
Whisk well.
Spread the cooked leeks over the pre-baked pie shell, taking care not to puncture the crust. 
Pour the egg mixture over top.
Bake at 325°F for 45 to 55 minutes, or until the custard is set and puffed.
The quiche will deflate as it cools. Slice into wedges and serve hot or warm.

Parmesan & Leek Quiche
A variation on the classic French cheese quiche, this Parmesan and leek quiche is rich and flavorful.
Ingredients
- 1 frozen deep-dish 9-inch pie shell
- 1½ tablespoons butter
- 1 cup finely chopped leeks, white and light green parts only, from 1-2 leeks
- 1½ cups heavy cream
- 4 large eggs
- 2 teaspoons finely chopped fresh thyme, or ½ teaspoon dried
- Pinch ground nutmeg
- 1¼ cups grated Parmigiano-Reggiano
- Salt and freshly ground black pepper
Instructions
- Preheat the oven to 400°F. Remove the pie shell from the freezer and thaw it until just soft enough to easily prick with a fork (10 to 20 minutes). Prick the bottom and sides all over with a fork and bake on the center rack until lightly golden, 10 to 15 minutes. Don't worry if the crust cracks while baking; see note below on how to fix it. Turn the oven down to 325°F.
- Melt the butter in small sauté pan over medium-low heat. Add the leeks and season with a bit of salt and pepper. Cook over medium-low heat, stirring occasionally, until very soft, about 15 minutes. Do not brown. Taste and adjust seasoning (they should be well-seasoned). Set aside to cool.
- In a medium bowl, whisk together the heavy cream, eggs, thyme, nutmeg, Parmigiano Reggiano cheese, ¼ teaspoon salt and ¼ teaspoon pepper. Mix well.
- Spread the cooked leeks over the pre-baked pie shell, taking care not to puncture the crust (it may be fragile around rim, or where there are air bubbles). Pour the egg mixture over top. Bake at 325°F for 45 to 55 minutes, or until the custard is set and puffed. The quiche will deflate as it cools. Slice into wedges and serve hot or warm.
- Notes: Be sure to clean the leeks well, especially between leaves where there can be a lot of grit.
- Note: Don't panic if your crust cracks -- you can easily fix it. Make a smooth paste by mixing 1 tablespoon of flour with 1 tablespoon of water. Use your fingers to patch up and fill any cracks, then place the crust back in the oven for a minute or so to set. It should be good as new.
- Make-Ahead/Freezer-Friendly Instructions: This quiche can be made up to a day ahead of time and refrigerated. To reheat: Cover the quiche with aluminum foil and bake in a preheated 300°F oven for 35 to 45 minutes, or until hot in the center. It can also be frozen for up to 3 months. Remove the quiche from the freezer about 24 hours prior to serving and reheat it, covered with foil, in a 300°F oven until hot in the center.

Delicious, and I never used a frozen crust before in my life! Jenn is exposing me to all sorts of wonderful short-cuts, and I’m totally grateful. I did change the recipe, though. More leeks, and wonderful aged Gruyère instead of Parmesan. Oh, and I served it with the yummy roasted beet salad.
Made this today, and it was everything I wanted from a quiche. I had some fresh chives I needed to use up so I added them along with the cooked and cooled leeks. My new favorite quiche recipe. Thank you for another winner!
I made this almost as written but for the leeks – I used more, as I needed to use them up 😉
Even the sometimes picky kids came for seconds, so this is definitely a keeper!
I combined it with your french grated carrot salad and a basic green salad with just a drizzle of real balsamico and good quality italian olive oil.
Superb!
I used sliced Yukon gold potatoes on the bottom instead of a pie crust. Baked them first, then spread the leeks on top then the mixture. Really delicious. A definite redo.
Hello! Love your recipes!! Can this be made crustless, like the broccoli quiche?
Thanks and Happy New Year.
So glad you like the recipes! And this should work as a crustless quiche — it will just be a little more delicate. I’d love to hear how it turns out!
I have made this recipe many times–it’s stellar. Over the years I have shared portions with my neighbours–they love it too! This past weekend, my neighbour made it (I had given her the recipe) and it was such a joy to receive a portion of it without expending time/energy in putting it together myself.
We make a two-inch deep version using a large, 2-piece tart tin with removable bottom, about 9.5″ – 10″ diameter, 2″ high. Ingredients and baking time are adjusted to allow for the larger baking pan.
If you are looking for a fabulous quiche recipe, look no further.
I have made all your quiches and my husband and I loved them all however this was our favorite! The silky custard with the sweet leeks and parmesan cheese smelled heavenly while in the oven. My husband said this was as good as a pizza. Quite a compliment from a Chicago guy!
This was my first-time making quiche, and it has turned out fantastic. I doubled the amount because I wanted a tall pie, and I made it crustless (following the cream/eggs ratio for your crustless broccoli quiche).
Thank you so much for the recipe – this was the best tasting quiche I have ever had. Smooth, fluffy, delicious, creamy perfection. My brunch guests were raving as well.
Made this today for my visiting adult sons. They loved it! I made two and to the second one I added chunks of ham. Very tasty! Definitely will make again.
Made this pie exactly as stated in recipe except I used 1/2 cup each or Parmigiano -Reggiano & Pecorino-Romano, …and it is wonderful. Absolutely delicious.
Thank you,
Richard Schinella
