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.

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.

Before this recipe, I’d never had leeks before. I made this quiche 4 times over the holidays for various friend and family gatherings. It’s absolutely yummy. Now I keep a bag of frozen chopped leeks in the freezer and a wedge of parmesan so I can whip up this quiche again when the mood strikes.
I absolutely love this quiche! Made it as listed with just a bit more leeks than 1 cup. Fantastic flavor and the crust was not soggy! Absolutely perfect!
Hi Jenn, I’d like to make this for a friend, who needs to be on a low-carb diet. Would this quiche work without the pie crust? And could I just follow your recipe but leave out the crust? I’ve recommended your website to all of my friends. All of your dishes are great!
Hi Jane, You could make this without the crust (and yes just follow the directions minus the crust part) but I actually might recommend my Spinach & Gruyere quiche as a better option — it’s a bit more substantial.
YUMMY!! I followed the recipe exactly except made my own crust. I think I didn’t add enough S&P while sautéing the leeks, so I’ll remedy that next time.
We had this for dinner and it was wonderful !! Great flavor and easy to prepare (once you get the leeks clean). This will become part of our monthly meal rotation.
This recipe turned out beautifully for me, just like so many others on your site – thank you so, so much!
Just a quick question – I’ve just booked my first catering gig for an upcoming holiday party. The hostess sampled this quiche and absolutely loved it but she said she’d prefer mini quiches that guests can pick up and add to their plates.
Do I need to make any adaptations to the recipe or cooking process in light of this?
Thanks, again!

They would not need as much time to cook–maybe cut the cooking time in half and keep an eye on them :).
Thanks so much! 🙂
Just want to say that this is the best ever quiche I’ve ever made. It was just as good the next day. And it was so fluffy, too. Love, love, love this recipe! Thank you for sharing this Leek Parm recipe. R
I make this often. Easy breakfast and lunch item.
Fantastic recipe! At last, a quiche that turns out fluffy, without having to add any flour! I substituted 1 cup nonfat milk; 1/2 cup half & half to lower some fat. I also added 1/2 finely chopped fennel bulb, sauteed same as leeks, but with half butter, half olive oil. Last, I added 1 cup thinly sliced sautéed mushrooms. The blend of flavors was delightful! I use the same brand frozen wheat crust – our family’s fav! I’ve never prebaked the crust before, and loved the improved texture and flavor!Thank you for sharing, I can’t wait to explore your recipes further!
Loved this, even better than the spinach gruyere quiche which we thought was amazing. I did use 3/4 1% milk and 3/4 heavy cream to make it a little less calorie laden and it was still delicious!
