JUST Egg makes preparing delicious vegan quiche recipes at home so easy!

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

What is JUST Egg?

JUST Egg is a plant-based liquid alternative to eggs that is made with yellow kidney beans. It’s scrambled just like chicken eggs and can be used as a vegan alternative to eggs in a variety of dishes like this quiche, as well as omelets, frittatas and more. You can usually find JUST egg products in the dairy/egg aisle or in the vegan section of the grocery store.

Ingredients you will need

vegan quiche ingredients laid out on a white background.
  • Egg only: You will 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 without the animal products!
  • Vegetables: For color, I use red onion and red pepper. You’ll also use a full 5oz package of fresh spinach – it cooks so much that it all fits! You can use other vegetables if you prefer: zucchini, mushrooms, corn, etc.
  • Vegan cheese: for a bit of cheesiness, i like to add some grated 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 black salt goes a long way. To get that classic egg 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 you have black salt? Just use a little sea salt.
  • Vegan Pie Crust: to make this quiche super simple, we just use a ready-made vegan pie crust from the freezer. I really like the Wholly Wholesome one. You can also use puff pastry or homemade pasta dough.


  • Tomato, pesto and feta: add a couple tablespoons of pesto to the egg mixture, a handful of chopped cherry tomatoes, and replace the grated 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 can also try vegan bacon instead of vegan sausage.
  • Broccoli and Cheddar: substitute 1 1/2 cups chopped fresh broccoli for the bell pepper and chopped spinach.

Step by step

Step 1: Add the olive oil, red onion and chopped peppers to a pan over medium heat and sauté until soft. Stir in the chopped fresh spinach and sauté until wilted.

Second step: Add the sauteed vegetables, Just Egg, black salt and cheese to a large bowl and toss to combine.

Step Three: Pour the Just Egg mixture into the pie shell and bake for 35-40 minutes until the center of the quiche is firm and the top is beginning to brown.

Four steps: Let cool for about 5-10 minutes before slicing to serve! Garnish with fresh herbs such as chives if desired.

Expert advice

  • No need to pre-bake/blind bake the crust: I have made this quiche a few times and found that there was no need to pre-bake the pie crust before adding the filling.
  • Bake in a baking tray: Place your quiche on top of a baking sheet if you’re afraid of spillage due to an unstable, disposable cake, or you just want a more stable surface to transfer to the oven.
  • Storage: Cooked quiche will last up to 3-4 days in the refrigerator stored in an airtight container. Reheat for 5 minutes in the toaster oven or 1 minute in the microwave.
