Real vegans eat quiche, like this fabulous vegan spinach mushroom quiche!

I love 'veganizing' old family recipes, but there are some traditional dishes that are almost impossible to make without certain key ingredients - like quiche - which is basically an egg and cheese pie.

Over the years, I've made a few unsuccessful attempts trying to create a recipe for vegan quiche that really worked. The flavor was amazing but the texture and consistency wasn't quite right. There are lots of recipes out there using tofu, and don't get me wrong - I like tofu - just not in quiche. I was on a mission to create a perfect vegan version of a traditional quiche, capturing just the right texture and taste but without tofu.

What to use instead of egg in a vegan quiche?

Problem was, up until recently, there just weren't any suitable egg replacers that worked well for quiche. Until now.

Thanks to the talented geniuses at JUST, we home cooks now have JUST Egg, a vegan egg substitute that requires no mixing or preparation. Straight from the bottle, it's ideal for egg-centric dishes, like quiche. I found that out when my daughter and I decided to prepare her grandma's traditional spinach quiche recipe using JUST Egg instead of eggs. Oh WOW. We nailed it, creating the best vegan spinach mushroom quiche!

What an amazing recipe! I made it again this weekend. Thanks for the game changing brunch idea! Denice K.

What is the best vegan cheese for quiche?

There's never been a better time to be vegan. With so many fabulous options in non-dairy butters and cheese, you can enjoy many of your favorite traditional cheese-centric dishes using all vegan ingredients.

For this quiche recipe, I suggest using a variety - two or three - different types of cheese. Most vegan cheeses tend to be softer than dairy cheese. That's ok. Just find cheeses that you like. Here are some of the cheeses we like and have used at various times in this recipe:

Miyoko's Creamery - Cream cheese, Cultured Cheddar, & Mozz
Kite Hill - Cream cheese & Ricotta
Chao - Cheese slices
Violife - Parmesan

This scrumptious, easy vegan quiche recipe is ideal for brunch, lunch, dinner, Mother's Day or any day!

How to make vegan quiche

I know I say this a lot, but this recipe is easier to prepare than you might think. Yes, there are several steps involved, but each one is fairly simple to do. You can save time by using store-bought pie crust, but making your own homemade vegan pie crust is fun and easy to do.

First thing you should do is watch my quiche video. It offers lots of helpful tips that will make your quiche baking experience that much better. Be sure to read through the step by step instructions and ingredients list for making the best vegan spinach mushroom quiche. 🥕Note: Since filming the video, I have reduced the amount of butter used to prepare the filling. Follow the quantity listed in the printable recipe card below.

Make your own easy vegan pie crust

I recommend making your own pie crust. There is nothing quite like a flaky homemade crust. It's easy to do and so much better than store-bought, but you can certainly use a pre-made pie dough if you don't have time to make your own. I also suggest watching my pie crust video.

🥕Variations

You can add or substitute a variety of veggies in this recipe like:

Broccoli
Cauliflower
Peppers
Asparagus

🥕 Top Tips

Here are a few simple tricks to make sure your quiche sets firmly after baking.

Be sure to use JUST Egg. I have not yet found other egg replacers that work well in quiche.
Cooked spinach will retain water, so be sure to press out the liquid or give it the good ol' Popeye squeeze to thoroughly drain any excess liquid from the spinach before adding other ingredients.
Soft vegetables like tomatoes and zucchini will add extra liquid to your quiche. If you decide to use either in your quiche, I suggest removing the pulp and seeds, otherwise it might not fully set.
Oven temperatures can vary, and altitude can also affect baking time, so you may want may to adjust the baking time, as needed. To protect your pie crust from getting too brown, wrap a narrow foil collar around the edge of the crust or use a pie crust shield.
The quiche will continue to set after baking. If after cooling for 30 to 60 minutes, it still isn't as firm as you like, try refrigerating the quiche for a little while.

We love making this quiche a lot! Here are a few we've whipped up!

Notes

🥕Important - The volume of spinach will reduce a lot when cooked. You'll need approx. 1.5 pounds fresh spinach, which will yield about 1.5 cups cooked. Make sure to thoroughly drain any excess liquid from the spinach before adding other ingredients.

🥕JUST egg vegan egg substitute is a key ingredient in this recipe. I've tried others, but this is the one I've had the most success with in this recipe. If you can't find it in a local store or on Amazon, check the JUST egg company website.
