An easy recipe for gluten-free spinach quiche. Made with a homemade gluten-free crust and filled with a rich and cheesy spinach filling.

Gluten-Free Quiche

Making a homemade gluten-free quiche is easier than you think! This gluten-free spinach quiche recipe starts with our easy Gluten-Free Pie Crust. If you’re short on time, you could also buy a premade gluten-free deep dish pie crust but nothing tastes quite like a pie crust made from scratch.

Once you have your gluten-free crust, we can move on to the cheesy spinach filling. This filling takes just a few minutes to put together but needs close to an hour to bake in the oven so make sure you calculate that time into your dining plans.

It only takes a few simple ingredients to make this gluten-free quiche recipe. You can see just how easy this gluten-free spinach quiche is to make in the detailed recipe step photos.

Ingredients In Gluten-Free Spinach Quiche

• Gluten-Free Deep Dish Pie Crust (9”): use our recipe for a homemade gluten-free pie crust. If buying a premade gluten-free pie crust, make sure that it’s a deep dish so that it’s able to hold all the fillings without overflowing.
• Unsalted Butter: a little bit of butter is needed to sauté the onion and the garlic.
• Yellow Onion: a sweet onion is preferred in this recipe but you could substitute it with white onion.
• Garlic: the garlic packs a punch of flavor into this spinach quiche.
• Half & Half: for the rich, creamy taste in the quiche.
• Sour Cream: a little bit of sour cream adds to the creamy texture of this spinach quiche.
• Eggs: eggs are the star of the show in this recipe. A quiche wouldn’t be a quiche without eggs.
• Salt: to help bring all the flavors together.
• Pepper: for just a little extra kick of flavor.
• Frozen Chopped Spinach: frozen and thawed spinach works best to get the most flavor packed into this quiche.
• Sharp Cheddar Cheese: sharp cheddar brings a nice flavor to compliment the spinach in this recipe.
• Parmesan Cheese: just a little bit of Parmesan cheese adds quite a bit of flavor to this spinach and cheese quiche.

How To Make Gluten-Free Spinach Quiche

• Start with a thawed but cold 9-inch gluten-free deep dish pie crust. Leave the pie crust in the fridge until you’re ready to fill it. See our recipe for a homemade gluten-free pie crust.
• Preheat the oven to 350° F.
• In a small frying pan, sauté the butter with the onion (over low heat) until the onions have softened and look clear. (photo 1)
• Add the garlic to the frying pan (still over low heat) and sauté for an additional minute or two. Be careful not to burn the garlic.
• Remove the frying pan from the heat and set it aside for now.
• In a medium bowl, whisk together the half and half, sour cream, eggs, salt, and black pepper until well combined. Set aside for now. (photo 2)
• Sprinkle the onion and garlic evenly over the base of the unbaked gluten-free crust. (photo 3)
• Be sure to squeeze all the extra liquid out of the thawed spinach. Use paper towels to squeeze out as much water as possible. Extra water in the spinach will water down this recipe and the quiche won’t set properly
• Start to sprinkle the spinach, shredded cheddar and shredded Parmesan into the pie shell. Alternate layers of spinach and cheese while sprinkling them into the pie shell. (photo 4)
• Set the pie plate on a baking sheet to catch any spills that may happen during baking. This also makes it easier to place the quiche into the oven and remove it from the oven.
• Pour the egg mixture evenly over the other filling ingredients in the pie crust. (photo 5)
• Bake for 50 to 55 minutes. The sides of the quiche will look set and the middle will be slightly wobbly. Remove from oven and let sit on top of the stove for 25 minutes before slicing and serving. This allows the quiche time to set up properly after removing it from the oven. (photo 6)
• Serve warm.
• Allow the leftovers to cool to room temperature then store leftovers in an air-tight container in the refrigerator for up to 3 days.

Tips For Making The Best Gluten-Free Spinach Quiche

• Be sure to squeeze all the excess water out of the thawed spinach. If there is excess water in the spinach, it will prevent the quiche from setting properly. Keep in mind that the 10 ounces of spinach called for in this recipe is the weight of the spinach when it is frozen. The weight is reduced by more than half after you’ve squeezed the excess water out and that is exactly what we’re looking for here. After squeezing all the excess water out, you’ll end up with about 4 ounces of chopped spinach and that’s okay.
• Shred the cheeses yourself and don’t buy the pre-shredded cheese. The pre-shredded cheese has a coating on it to prevent clumping but also prevents the cheese from melting properly. For the best results, buy blocks of cheese and do the shredding yourself.
• Full-fat sour cream is best in this recipe. Using low-fat milk or sour cream will take away from the richness and creaminess of this spinach quiche.
• Prebaking the gluten-free crust is not necessary for this recipe but if you want your crust to be crispier you can par-bake (partially bake) the pie crust before adding fillings. See our gluten-free pie crust recipe for instructions on prebaking and par-baking the pie crust.

How Long Does It Take To Make Gluten-Free Quiche?

It takes about 10 minutes to prepare the filling for this gluten-free spinach quiche but the baking takes almost an hour. Keep in mind you also have to let the quiche cool for about 25 minutes before slicing.

Can I Freeze Gluten-Free Quiche?

Yes, this gluten-free spinach quiche can be frozen. After the quiche has fully cooled, wrap individual pieces of quiche well in plastic wrap and place them in a plastic freezer bag or a freezer-safe container in the freezer for up to 2 months. Thaw the quiche in the refrigerator overnight then reheat in the oven at 350°F or in the microwave before serving.

How Do I Reheat Leftover Gluten-Free Quiche?

Reheating leftover gluten-free spinach quiche can be done either in the oven or the microwave. In the microwave, 30 seconds (on high heat) is enough time to reheat the refrigerated quiche. In the oven, reheat for 15-20 minutes at a temperature of 350° F.

Can I Make Gluten-Free Quiche Ahead Of Time?

Gluten-free quiche really is a full meal already but if you’d like to serve it with something on the side for brunch, try something sweet like our Gluten-Free Cinnamon Rolls. This gluten-free spinach quiche doesn’t include meat so a side of bacon or our Homemade Turkey Sausage Patties would be a good savory option.

How Long Is Gluten-Free Quiche Good For?

Gluten-free spinach quiche can be stored in the refrigerator for up to 3 days or in the freezer for up to 2 months. Be sure to wrap it well in plastic wrap or place it in an air-tight container so that it doesn’t dry out. Let the quiche cool completely before moving it to the refrigerator or freezer for storage.

Can I Make A Crustless Gluten-Free Quiche?

You can definitely skip the step of using a gluten-free pie crust and make a crustless quiche. Simply grease the pie pan with gluten-free cooking spray and follow the recipe steps to make the filling. Bake the egg filling for 50 to 55 minutes. 

Ingredients Substitutions For Gluten-Free Spinach Quiche

• If you don’t have half and half, you can substitute it with half whole milk and half heavy cream.
• The sweet yellow onion can be swapped for a white onion.
• The sharp cheddar cheese can be swapped with another cheese like Swiss or Gruyère.

What Other Ingredients Can I Include In a Gluten-Free Quiche?

Meats like ham or bacon are also a popular addition to a quiche recipe. Keep in mind that this particular quiche recipe is already maxed out in volume with the spinach and cheeses, so if you add more ingredients to it, it will overflow out of the pie shell.
