JUST Egg makes whipping up delicious vegan quiche recipes at home so easy! I had been making vegan quiche with silken tofu in the past which meant I had to dig out my food processor to make it and do a bunch of extra dishes. In this spinach quiche recipe with the vegan egg substitute JUST egg, you’ll just sauté your veggies, mix them with your JUST egg, and cheese and bake!

We’re using a store-bought crust for an even simpler preparation for this vegan JUST egg quiche. I added red onion, red peppers, and spinach to this version for tons of flavor, color, and fiber. However, you can switch up that add-ins based on your preferences.

What is JUST Egg?

JUST Egg is a liquid plant-based alternative to eggs that is made from yellow mung beans. It scrambles just like chicken eggs and can be used as a vegan-friendly alternative to eggs in a variety of dishes like this quiche as well as omelettes, frittata and more. You can usually find JUST egg products in the dairy/egg aisle or vegan section of the grocery store.

Ingredients You’ll Need

vegan quiche ingredients laid out on a white background.

Just Egg: You’ll use an entire bottle of Just Egg as the main ingredient for this quiche. It adds all the classic texture of an egg based quiche but with no animal products!
Veggies: For color, I use red onion and red bell pepper. You’ll also use a full 5 oz package of fresh spinach – it cooks down so much that it all fits! You can use other veggies if you prefer like: zucchini, mushrooms, corn, etc.
Vegan Cheese: for a little cheesiness, I like to add some shredded vegan cheddar cheese. You can really use any vegan cheese like vegan mozzarella that you like in this quiche.
Black Salt (Kala Namak): a little bit of black salt goes a long way. To get that classic eggy taste in this vegan quiche, you’ll want to use this secret ingredient. Pick up some black salt from Amazon for all your vegan egg recipes. Don’t have black salt? Just use some sea salt instead.
Vegan Pie Crust: to make this quiche super simple, we just use a pre-made vegan pie crust from the freezer. I really like the one from Wholly Wholesome. You can also use homemade pie crust or puff pastry.

Variations

Tomato, Pesto & Feta: add a couple of tablespoons of pesto to the egg mixture, a handful of chopped cherry tomatoes, and replace the shredded vegan cheddar with 1/3 cup crumbled vegan feta.
Sausage: add a couple of chopped vegan breakfast sausages to the quiche egg mixture before baking. You could also try it with vegan bacon instead of vegan sausage.
Broccoli & Cheddar: replace the chopped pepper and spinach with 1 1/2 cups fresh broccoli chopped into small pieces.

Step by Step

Expert Tips

No need to pre-bake/blind bake the crust: I’ve made this quiche a few times and I found there was no need to pre-bake the pre-made pie crust before adding the filling.
Bake on a baking sheet: place your quiche on top of a baking sheet if you are afraid of spilling due to an unstable disposable pie dish or just want a more stable surface for transferring it to the oven.
Storage: cooked quiche will last up to 3-4 days in the refrigerator stored in an airtight container. Reheat 5 minutes in the toaster oven or 1 minute in the microwave.
