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!

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
- Vromage – Small batch Artisan cheese
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.
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.

How to make an 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
🥕NOTE: Soft vegetables like tomatoes and zucchini will add extra liquid to your quiche, so you may need to remove the pulp or let your quiche bake longer, otherwise it may not fully set.

A new favorite! This quiche is SO GOOD, my non-veg friends love it as much as I do.
Summer – Yay! Everybody loves this quiche 💚 So happy you enjoy this recipe! Thanks a bunch for sharing!🥕
Absolutely delicious.
Cindy – I’m so glad you love the quiche recipe! Thanks a bunch for letting me know!🥕💚
Thank you for this recipe! Mine turned out great! I wasn’t sure how the Just Egg would cook when mixed with soymilk, but it turned out like a real quiche!
Hi Lara! So glad you gave the quiche recipe a try and loved the results! Once we figured out the right combination of ingredients and using JUST egg, we now make quiche all the time. It’s a great time to be vegan! Thanks so much for sharing your experience & happy cooking! 🥕💚
Looks Great. Going to give it a try. (Note it’s Julia Child. not “Childs”.)
Love to hear how your quiche turns out! Thanks for the correction & bon appétit!🥕
Hi Connie. I have made this 2x now. I didnt combine egg mixture with veges in the pan that veges cooked in. I added cooked veges to egg mixture in the bowl egg mixture was in. I am wondering with the pan being warm allows the mixture to set better. I cooked for about 1 hour after the cheese was added to ensure the quiche was more firm. This 2nd time it could still be more firm. I used fresh spinach and did not add any liquid from the pan. It has been delish 2x now, just needs a bit of perfecting. I also used unsweetened almond milk. Any thoughts?
Hi Desiree! First of all, I’m so glad that you loved the flavor of the first quiche enough to try it again a second time. Here are my thoughts about why it hasn’t set firm enough. It’s super important to squeeze out all the liquid from the spinach before adding it. I either press it in a mesh strainer or physically squeeze it in my hands. If you’ve done that, I would recommend pouring your egg mixture into the hot pan with the veggies because it likely helps begin the cooking process for the eggs. I always do it that way. Lastly, I would try refrigerating the quiche. I’ve found it sets firmer in the fridge, You can reheat it in a low oven or in a microwave. I would love to hear if you decide to give it a go again. You know, third time’s the charm! 💚🥕
This vegan spinach mushroom quiche continues to be a fan favorite. If you love quiche – this is the recipe to try. It’s a winner!
Do you think this would freeze well?
Hi Susanne! Honestly, I’ve never had enough leftover quiche to try freezing it – we tend to devour it too quickly!😁 I can imagine it would freeze fine. If I were to try it, I would bake it first, let it cool completely and store it in a large freezer bag or container inside the freezer. To reheat it, I would cover it in foil and place it on a cookie sheet in a pre-heated 350º oven for at least 30 minutes. If it isn’t hot all the way through, I would continue baking it in 5-10 minute increments until ready. If you bake smaller individual size quiches, then you could reduce the bake time, probably by half. Hope this helps & please let me know if you give it a try!💚🥕
I am looking forward to making this recipe later tonight. I know it says unbaked pie crust however, I opted to get a pre-made whole wheat frozen crust. should I bake the crust a bit before adding quiche mix in?
Hi Kaeleigh – I wouldn’t pre-bake the crust but would let it thaw prior to adding the filling. Love to hear how it turns out!
I haven’t had a quiche since going vegan and was super excited to try this out. Came out SO good! I would suggest adding black salt if you have it (this is an Indian spice that gives an egg like flavor). Thanks for sharing this 🙂
Lea – I’m so happy you enjoyed the quiche! The addition of kala namak (Himalayan black salt) is a good idea! A little bit goes a long way, so I would use maybe 1/2 tsp. Thanks a bunch! 🥕
Wow–so good! This truly was the quiche that my family has been missing ever since we’ve been eating vegan. I made just 1 quiche to see how it would turn out–and my husband and 3 teen boys promptly devoured it! This will definitely become a staple at our house, just as traditional quiche used to be. Next time I’ll definitely make 2 of these, and I’ll try making your homemade pie crust, too. Thanks so much for a delicious recipe!
Wow Kim! Your reaction sounds a lot like my family’s when we finally dialed in this recipe. It was like a wonderful visit with a long-lost friend. I’m so happy that you and your guys have quiche back in your lives again! Thanks so much for sharing!🥕💚
