Vegan Quiche Recipe with Mushrooms, Spinach and Leeks (1)

For a winning breakfast or brunch, try my Easy Vegan Quiche recipe! Just the thing to serve to a hungry crowd. The filling is savory and cheesy and packed with flavor from sautéed mushrooms, leeks, and spinach. I like adding some sun-dried tomatoes in the end but fresh tomatoes work just as well, especially when they are in season.

While many vegan quiche recipes call for pre-made pie crust, I opted to make my pie crust from scratch and I recommend you try it too! The pastry comes together in a food processor within minutes and is just perfect. Rich yet tender, and it holds up well, too.

Ingredients

For the pie crust:

  • 3/4 cup (0.75 g) plus 2 tablespoons flour I use all-purpose. You can also use oat flour to make it gluten-free.
  • 3/4 cup (85 g) plus 2 tablespoons, almond flour
  • 1/2 teaspoon salt
  • 2 teaspoons flaxseed meal mixed with 2 tablespoons of water
  • 1/2 teaspoon oregano
  • 1/4 teaspoon thyme these herbs are optional
  • 4-5 tablespoons non-dairy milk

For the filling:

  • 14 ounces (400 g) firm tofu pressed for 5 mins
  • 1 tablespoon flour or use chickpea flour
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon Indian Sulfur salt or Kala Namak
  • 1/2 teaspoon salt
  • 1/2 teaspoon turmeric
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon onion powder
  • 1-2 tablespoons nutritional yeast
  • 2 tablespoons water

To mix into the filling:

  • 1 teaspoon oil or use 2-3 tbsp broth to sauté to make Oilfree
  • 3 garlic cloves minced
  • 3/4 cup chopped leeks
  • 1 cup thinly sliced mushrooms
  • 1/4 tsp salt
  • 3/4 cup frozen spinach thawed and squeezed lightly

Instructions

  • Make the Pie crust: In a bowl or food processor, add the flour, almond flour, salt, herbs, and pulse or mix. Add in the flax egg and mix in.

  • Then add in 4 tablespoons of non-dairy milk and mix well or process 10-15 seconds

  • If the dough is somewhat dry, add in more non-dairy milk, 1 teaspoon at a time until you can make a dough which is somewhat sticky and crumbly, not necessarily all together, but sticks when you press.

  • Press this dough into a greased 9 inch tart pan (or use a pie pan) . Use a fork to create holes in the dough. Then bake at 350 degrees Fahrenheit (180 c) for 13 minutes.

  • Meanwhile for the filling: heat up oil in the skillet over medium heat. Add the garlic and cook for half a minute. Then add in the leeks, mushrooms, and salt and continue to cook until the mushrooms are golden.

  • Once the mushrooms are somewhat golden, add in the spinach. Mix in and continue until the spinach moisture is evaporated for 3-4 minutes. Cool this mixture for 10 mins

  • Make the tofu egg mixture by adding all of the ingredients to a food processor with 2 tablespoons of water and processing it until the mixture is somewhat smooth.

  • Mix your mushroom leek filling in this mixture and then transfer it to the baked pie crust.

  • Even it out. Top it with some cherry tomatoes or sun-dried tomatoes and bake for 30-35 minutes.

  • Once the center is set and not jiggly, the quiche is done. Take it out of the oven and let it sit for 10 minutes before slicing and serving.

Notes

  • Use oat flour or Glutenfree blend instead of all purpose to make the first Glutenfree.
  • To make this Soyfree, use my chickpea flour frittata mixture
  • If you're pressed for time or for Nutfree crust, you can use a regular flour and vegan butter crust or store-bought pie crust. Many pie crusts are vegan by default and some are labeled vegan. Just check the ingredients before you purchase.
  • Add in flavors such a Italian blend or chopped sundries tomato to the tofu egg mixture for variation

Ingredients:

  • a blend of almond flour and flour makes for a crispy yet rich crust. Use oat flour or GF blend to make it glutenfree
  • flax egg made from flax meal and water is our stand-in for egg
  • the crust is seasoned with oregano and thyme for that Mediterranean twist
  • for the filling, we blend some firm tofu with some flour or chickpea flour for thickening
  • to give the tofu a quiche’s signature savory-cheesy-eggy flavor, we use add nutritional yeast and sulfur salt as well. as onion powder to the filling
  • turmeric lends the filling its gorgeous color
  • For my quiche filling, I like garlic cloves, leeks, sliced mushrooms and spinach

Tips & Tricks:

  • You can use Italian Seasoning / Italian Herb Blend for the crust
  • If you’re pressed for time or for Nutfree , you can use a store-bought pie crust. Many pie crusts are vegan by default and some are labeled vegan. Just check the ingredients before you purchase.
  • For Glutenfree, use a gf blend or oat flour instead of all purpose
  • For Soyfree, try my chickpea flour frittata filling.
  • I suggest pressing the tofu for the filling for at least 10 minutes because the filling might get a little too soft depending onthe water content of the tofu
