Vegetarian Leek & Cheese Quiche Recipe | Aline Made (1)

This flaky, creamy, and cheesy vegetarian quiche is best served warm out of the oven! It makes for outstanding finger food at any party, savory brunch, or served as a weeknight family dinner alongside this green salad.

Leek and cheese harmonize very well together and do taste incredibly delicious served in a homemade quiche crust. This recipe is very similar to Quiche Lorraine, only that it’s vegetarian and therefore made without bacon. No worries, you won’t miss the bacon.

The combination of sautéd leeks, aged cheese, and the typical French quiche filling made with heavy cream and eggs comes with a decent amount of flavor and is a tasty treat for all veggie quiche fans!

What to love more about this leek quiche recipe is that you can prepare and bake it in advance – once your guests arrive, reheat it for a few minutes in the oven, and it tastes as if freshly baked!

Homemade Quiche Crust

Quiche should always be prepared with a homemade crust – just my two cents! Why? Homemade crust tastes better than any store-bought version – buttery, crispy, flaky!

Plus, it’s not super complicated nor time-consuming. You can even prepare the crust one day in advance if stored in the refrigerator = even less stress when baking!

I won’t judge if you are lazy or just not that much into baking but still want to serve a hearty meal for your family! Go for the store-bought pie crust in this case! 😉

Recipe FAQ & Tips

How long does it stay fresh?Leftovers can be stored for up to 3-4 days in the refrigerator. Store it in an airtight container, or wrap the cold quiche pan with plastic wrap/aluminum foil (easiest to reheat).

How do I reheat quiche?Reheat for 15-20 minutes in the preheated oven at 390°F (200°C).

Gluten-Free?Prepare the dough with gluten-free flour or use a store-bought gluten-free pie crust.

Looking for a dairy-free quiche recipe?Go for plant-based butter, dairy-free heavy cream, and a dairy-free cheese alternative (make sure it’s one that’s melting). → I usually bake my quiche with plant-based butter & heavy cream but opt-in for regular Gruyère cheese.

Egg Replacement: The egg for the quiche crust can be replaced with 3-5 tablespoons of cold water – although the crust won’t turn out as crispy as when using an egg. Unfortunately, you can’t replace the eggs in the quiche filling as they are needed for the texture!

FAQs

Should vegetables be cooked before putting in quiche? ›

Cook the Veggies First

"Vegetables will take longer to cook than your egg custard, so always sauté onions, steam broccoli, etc. before you add them to your egg mixture to ensure every bite of quiche will be perfectly cooked," says Kristin Beringson, executive chef at Henley in Nashville.

What is the formula for quiche? ›

Quiche Ratio: 1 large egg to 1/2 cup of dairy

You'll need to increase the amount of eggs and milk based on the size of your quiche, so knowing the basic ratio makes it really easy to scale up or down. For a standard 9-inch quiche: Use 3 large eggs (6 ounces) 1 1/2 cups of whole milk or cream (12 ounces)

Can you use 2 milk instead of heavy cream in a quiche? ›

For gluten-free crust, try making a sweet potato crust. The Custard: For your custard to set properly in the oven, use this easy ratio: 1 part dairy to 2 parts eggs. Classic custards use heavy cream, but 2% milk contains a fraction of the saturated fat and is still plenty rich.

What not to put in quiche? ›

Using too many eggs in the custard. The best quiche consists of a custard that's the perfect ratio between eggs and milk. Using too many eggs in the custard results in a quiche that rubbery and too firm when baked, while not using enough will prevent the custard from setting.

Should quiche be cooked at 350 or 375? ›

BAKE in center of 375°F oven until center is almost set but jiggles slightly when dish is gently shaken and knife inserted near center comes out clean, 30 to 40 minutes.

What is the ratio of milk to eggs in a quiche? ›

The key to a foolproof quiche is the ratio of eggs to liquid – 2:1. I used 3 eggs and 1 1/2 cups liquid ( a mix of whole milk and heavy cream) – this is enough for a deep dish crust.

What is the best cheese for quiche? ›

Cheese: Some favorites include feta cheese, goat cheese, cheddar cheese, white cheddar cheese, Swiss cheese, and gruyere. Add-Ins: Add up to 2 cups add-ins including vegetables and meat/seafood. Most quiche add-ins should be pre-cooked and can still be warm when mixing into the egg filling.

Why do you put flour in quiche? ›

Add flour to your filling: Adding a bit of flour to your quiche filling helps absorb moisture and stabilize things in general.

Why does my quiche sink when I take it out of the oven? ›

Excess moisture is one reason why quiches collapse in a watery pool on your plate. Vegetables and meats like ham give off tremendous amounts of water when they're cooked. Therefore, if you're using vegetables in your quiche, it's imperative that you cook them first.

Do you need to prebake pie crust for quiche? ›

Some recipes like quiches recommend partially cooked pie shells because the baking time wouldn't be long enough to fully cook the dough otherwise. Pre-baking a crust can ensure that your pie or tart crust will be fully baked and browned, and not soggy.

Why is there liquid at the bottom of my quiche? ›

If the bottom crust doesn't set before the filling soaks in, it's going to be gummy. A metal pie pan placed on a preheated surface will set the bottom crust quickest; once cooked, the liquids from the filling above won't soak in, and as a result: no soggy bottom.

What is a vegan substitute for heavy cream in quiche? ›

Coconut cream

Coconut cream is a versatile ingredient that makes an excellent vegan substitute for heavy cream. While it can be purchased pre-made, it's also simple to make at home using coconut milk.

What is a substitute for heavy cream in a quiche recipe? ›

Use half-and-half as a 1:1 substitute for heavy cream. It can work nearly as well for bringing creamy texture and flavor to sauces, soups and stews, mashed potatoes, quiches, and casseroles.

What is a good substitute for heavy cream in quiche? ›

Recommended substitutes: Evaporated milk, whole milk, coconut milk, cashew cream, onion cream.

Why is my quiche always soggy? ›

Instead of using raw vegetables in quiche, the outlet recommends roasting or sautéing vegetables with a high moisture content before adding them to quiche: That way, they'll release the majority of their water before landing in the egg custard and reducing the chances that it will become soggy.

Should quiche crust be prebaked? ›

And yes, as you'll see, you should always prebake quiche crust to avoid a gummy pastry. Preheat the oven to 450°F. Roll out your homemade or purchased refrigerated dough into a 12-inch circle.

Why is my quiche watery? ›

Why does my quiche go watery? If your quiche appears watery it may just need to set for a little longer. The recipe may also contain too much dairy, so make sure that the recipe you are following has the ratio of 4 eggs to 1 cup dairy.

Should you cover a quiche while baking? ›

At 375F, it requires 25 minutes of baking time uncovered. At that point, you'll want to check things out because you don't want the crust to get too brown. If it's looking a bit well-done, cover it with aluminum foil and continue cooking for 10 more minutes.
