The Best Vegan Quiche Ever: Perfectly cheesy soy-free creamy filling over whole grain crust topped with crunchy asparagus. 40 minute easy recipe from start to finish!
Believe it or not but it’s the best vegan quiche I’ve ever tried. It also happens to be one of the easiest ones, taking 40 minutes to make from start to finish. No waiting for the crust to rest, no baking for an hour (in fact, the baking time is just 20 minutes + 15 minutes pre-baking), no boring tofu in the filling, and no white flour in the crust.
Instead, you have a flavorsome whole grain olive oil crust (you literally just need these two ingredients plus some salt and water) that is super easy to prepare, any veggies of your choice. Think:
- bell peppers
- dried tomatoes
- asparagus – because it’s spring!
Finally the most important part – delicious cheesy filling that I will reveal how to prepare down below, so keep reading. 🙂
When I first made this quiche, I was really looking forward to my husband to try it and let him guess what he thinks it is made of. Since he didn’t know the quiche was vegan, he took a bite and said: “Mmm, cheese!” But he couldn’t be more wrong. It’s true that it tastes like cheese but it’s completely plant-based. Intrigued? He was too.
One of my favorite quiche recipes is ricotta spinach quiche, but this time I challenged myself to make a vegan one and it turned out to be a complete success!
It took me a while to get ready to make this vegan quiche and take pictures, since my baby was interrupting the process instead of helping it 🙂 He just turned 3 months and he is seeking my attention whenever I seem to start doing something else than taking care of him. I finally found time for the quiche yesterday, when the weather was so good that it felt like summer.
I let the baby sleep on the balcony and he slept for whole three hours without waking up (yey!), so I had enough time for baking and shooting. So happy I did it yesterday because today he didn’t sleep for a minute! I was really looking forward to making this quiche not only because of the recipe itself but also because I bought a new quiche pan with removable bottom and was dying to bake something in it 🙂 And I’m more than happy with the result!
You can’t go wrong with this recipe. It’s so easy, your kids could make it. It’s seriously a matter of 40 minutes and baking time takes the most of it. Here is how to make this vegan asparagus quiche step-by-step.
How to Make Vegan Quiche Crust
Quiche starts with a crust. The easiest, the quickest, the healthiest and the most delicious vegan quiche crust is the one I used for this recipe. Seriously, look no further! Whole wheat flour, olive oil, salt, water and 5 minutes to knead and roll.
Transfer it to a rectangular quiche or tart pan (mine is 25 x 20 cm or 10 x 8 inch). You can also use other sizes like 14 x 6 inches, 12 x 12 inches or even round-shaped ones (if you’ll manage to arrange asparagus on it). Removable bottom definitely makes serving easier but if your pan doesn’t have it, it’s OK too.
Prick the crust all over with a fork and pre-bake in a hot oven for 15 minutes.
This crust is so universal, it’ll fit to whatever filling you want. For sweet tarts, put a bit less salt and add some sugar.
This vegan quiche crust doesn’t even require greasing of the pan, since it contains olive oil. It doesn’t stick to the pan at all, which makes it really easy to serve.
It has a rich taste by itself, nutty, aromatic, crunchy but moist. If you like baking with whole grains, you know what I mean. No other crust is a better addition to this vegan quiche!
How to Make Vegan Quiche Filling
Now when the crust is baking in the oven, we come to the filling. OK, it’s time to reveal the secret ingredient: soaked CASHEWS! They give the most creamy consistency to the filling. For the cheesy flavor I added Marmite (nutritional yeast will work too), which are both available on Amazon (yey!).
Other ingredients of this vegan quiche filling include lemon juice, water, garlic, herbs (oregano, thyme and wild garlic for spring flavor), nutmeg, a pinch of cayenne, salt and black pepper. Nothing too fancy, but believe me, it has tons of flavor and it’s almost impossible to believe it’s completely vegan unless you made it yourself.
So, to start with, soak the cashews over night. The longer the better as it gives the most silky structure to the filling. Wait, I should have started with this, right? No worries if you don’t have much time, 1 hour would be sufficient too. You will just probably have to pulse you cashews longer in your food processor or blender.
Place soaked cashews, garlic, water, lemon juice, nutmeg and a pinch of cayenne in the bowl of your food processor or blender. Pulse until smooth and silky. I really love my Phillips Avance blender and this time it worked perfect, making the filling very smooth and creamy. Highly recommended!
Add more water if you think it’s too thick (it should have the consistency of hummus or a bit thinner). Add chopped herbs, salt and black pepper to taste. In fact, you can already eat it. It’s delicious! Not only as a quiche filling, but also as a bread spread or pasta sauce. I should make more recipes with it!
Once you are done with the filling, it’s time to assemble the quiche.
How to Make Vegan Quiche
If you choose to use asparagus in your quiche (hello, spring!) I would recommend to blanche it first. Trim the ends and put asparagus in salted boiling water vertically (stems down) for 5 minutes. This way you will pre-cook the thickest parts of your stems while the tops will be nice and crunchy.
If you make your quiche with any other vegetables from the list above (except of dried tomatoes), you should pre-cook them too. The quiche takes 20 minutes to bake, so the veggies won’t be completely done if you put them raw into the pan.
Stir-fry or steam them before adding. If you are not sure how to prepare your veggies, leave a comment below and I’ll help you. I’ve done this quiche with zucchini as well and it worked great too.
Now when your veggies (asparagus in my case) are ready, spread the filling over the crust. Arrange asparagus on top and gently press it, so that it’s half drown in the filling.
Bake for 20 minutes or until he top is golden. The middle should be a little unset, but if you want it to be rather firm, increase the baking time to 30 minutes.
That’s it, the quiche is ready! Let it cool and enjoy! Check the full recipe below for more details. Hope you enjoy it!
