What makes this recipe for gluten free quiche so perfect
Whether you call it a gluten free breakfast for dinner, brunch or just a lovely French-style breakfast, mastering the art of the perfect gluten free quiche will come in very handy indeed. There's not a lot you need to know, but whatever I know, I've detailed right here.
The most lovely quiches start with a light and flaky pie crust. I have a favorite pie crust recipe here on the blog, my extra flaky gluten free pie crust. You'll need a single recipe, not a double one, since we are only making a single crust.
What's in the filling of this delicate, savory quiche?
I've made this quiche with a mushroom and cheese filling, since it's a classic, lovely combination. The key to any proper quiche filling, though, is in the ratio of eggs to milk or cream (see below)—and in the absence of too much moisture in the remaining filling.
If you're using mushrooms as I have, you must cook down the mushrooms so they release their moisture, and then leave the moisture behind. If using a blanched vegetable (frozen broccoli and/or cauliflower work beautifully), be sure to blot it dry before adding it to the filling. Failure to heed these moisture warnings will result in a sad, soggy quiche that never quite sets up!

How to make gluten free quiche
There are two main elements to any quiche: the crust, and the filling. The crust is light, flaky and buttery. The filling is smooth, creamy, rich with milk and cheese with some texture from lightly sauteed vegetables.
A single gluten free pie crust recipe
To make a quiche, you need a single 10-inch pie crust. A good pie crust is made with very cold butter and water, plus all purpose gluten free flour, baking powder, and salt.
Pie crust, like all pastry, is a combination of flour and water, and cold layers or chunks of fat, like butter. When the cold butter is surrounded by flour and water, it will expand and push out the dough and create flaky, crispy layers of pastry.
Here, we shape the pie crust, chill it to ensure it's very cold before it goes in the oven, then bake it half way without any filling. This is called parbaking, and it's the reason that the crust stays light and flaky even after we add the moisture of the filling.
To parbake a shaped and chilled pie crust in a pie plate, pierce the shaped pie crust to ensure that it doesn't bubble in the oven. Line the crust with a piece of parchment paper, and weigh it down with some dried beans or ceramic pie weights.
Bake the lined and weighted pie crust at 425°F for about 15 minutes or until it's beginning to brown.

The 4 main quiche filling ingredients
Once you've baked the crust, set it aside to cool a bit. It's time to prepare the filling. The proper quiche filling is a simple ratio or formula, much like a cheesecake filling is made of eggs, granulated sugar, and cream cheese.
A quiche filling has only 4 main ingredients in proper proportion, each related to how many eggs are in the filling. For each egg in your quiche filling, you'll need:
- 1/4 cup (2 fluid ounces) milk or 1/3 cup (2 2/3 fluid ounces) half-and-half;
- 1/2 cup not-too-wet cooked (or at least blanched) vegetable; and
- 2 ounces semi-hard cheese, grated.
The vegetables are cooked in some sort of butter or oil just until they're tender. If you don't saute the vegetables, they'll be too hard, especially as compared to the rest of the egg, milk and cheese filling.
Plus, cooking the vegetables first means that they will release at least some of their moisture, which can then be drained or cooked off. If you don't cook the vegetables a bit before baking them in the filling, you'll have a watery quiche.
Assembling the quiche
Once the crust is parbaked and the vegetables are cooked, it's time to assemble the quiche. First, place half of the grated cheese on top of the parbaked crust. Top with the cooked vegetables, followed by the remaining cheese.
Beat the eggs with the half and half or milk until well-combined, and pour that mixture on top of the vegetables and cheese.
Although we parbake the crust at 425°F, we'll reduce the oven temperature to 350°F to bake the filling and finish the quiche. It's done when the filling is set, and the edges of the crust are golden brown. Let the quiche sit until the filling is set, then slice and serve.

FAQs
A quiche made without a crust is usually gluten free, as long as there aren't any gluten-containing fillers or grains in the filling. A crusted quiche will always have gluten unless it's made specifically to be gluten free, since conventional pie crust is made with wheat flour.
Quiche filling is done baking when it is lightly golden brown on top, with just a tiny bit of jiggle in the center when moved from side to side. It will continue to cook a bit even after it’s removed from the oven, as it cools.
If you don't parbake the pie crust, it will probably be soggy after the filling is cooked in it. Plus, the filling will be overcooked by the time the pie crust browns fully.
Yes, if you use raw vegetables in your quiche, they will release their moisture during baking, leading to a watery filling, and they will be crunchy in an otherwise smooth and creamy filling.
Did you cook your vegetables first by sauteeing them, and drain or cook off the moisture before adding them to the filling? Did you use too much milk in your filling, or simply not cook it for long enough so that it was fully set?
Once your fully baked and prepared quiche is completely cool, you can freeze the whole quiche or individual slices. To freeze the whole quiche, I recommend slicing it into wedges and then wrapping the whole quiche in a tight-fitting freezer-safe wrap and freeze for up to 3 months. To freeze individual slices, wrap them tightly in freezer-safe wrap and freeze for up to 3 months.
Yes, you can follow the instructions for freezing the whole quiche just above, or you can make and/or parbake only the pie crust first, then add and bake the filling later. The prepared pie crust can be frozen as raw or baked, then baked or defrosted before filling and proceeding with the recipe as written.
Yes! You can make a quiche entirely crustless. Simply skip the ingredients and instructions that relate to the crust, and bake the filling right there in a greased pie plate. The baking time for the filling will not differ.
Yes! Mushrooms can be replaced with 10 ounces broccoli or cauliflower florets, blanched and blotted dry, or 1 pound frozen cut spinach, thawed and drained of most of its moisture.
Gluten free quiche ingredients and substitution suggestions
Dairy free quiche
The dairy in this recipe comes from butter, grated cheese, and half and half. You can try replacing the butter in the pie crust with vegan butter. Melt and Miyoko's Kitchen brands are the best.
For the grated cheese, you can use your favorite nondairy cheese, but be sure you're using something that melts and doesn't have a ton of moisture. Violife brand nondairy cheese blocks are excellent, but Daiya is usually quite good, too.
For half and half, there are some really good dairy free versions of heavy cream on the market. I'd recommend using half the volume as one of those, and half your favorite unsweetened nondairy milk. There are even some nondairy half and half milks, which would be ideal.
Avoid any nondairy milk that's nonfat, though, since fat provides richness and acts like a flavor delivery system, which is part of why fat free baked goods taste so bland. And don't ever replace half and half or cream with just plain nondairy milk, as they're not the same at all.
Eggs
I have not tried to make this recipe with an egg replacer, but I would not recommend trying any replacement that you would normally use for eggs when they're not the primary ingredient, like in baking a cake. You may be able to make this quiche with a beaten egg replacement like “Just Egg,” but I haven't tried so I don't know how well it bakes, especially in a custard like quiche filling.
How to serve this gluten free quiche
Everyone in my family cheers for a quiche, and it's even the stuff of birthday dinner requests around here. Serve it with a nice green salad, and you've got a meal to remember, elegant in its delicious simplicity.
















enjoy finding really great recipes. love this site.
Could this filling be used without the crust, in cupcake liners/pan to be like a frittata ? How long would you bake them?
I’ve never tried that, Regina, so feel free to experiment!
Can I make the crust the day before and let it sit in the fridge until ready to roll out? AND, can I make it the day before, roll it and place in the quiche dish and let that sit in the fridge overnight and then just add the filling when ready to bake?
Hi, Lisa, for instructions on handling the gluten free pie crust, I recommend you see the full post for that recipe.
This pastry makes a lovely quiche.
Great recipe! I use it as a guide to make all pastry either sweet or savoury without xantham gum which makes me ill. I’m very pleased with the results.
