Ingredients and substitutions

  • A Pie Crust – I have included my favorite easy vegan pie crust recipe, but you can use your own, or even buy a premade pie crust to keep it simple.  If you need it to be gluten-free, be sure to use my recipe for a Gluten-Free Vegan Pie Crust!
  • Tofu – this is the base of this recipe that you need to use to replace the eggs. Use high protein or extra firm tofu.  The more firm, the better. 
  • Nutritional Yeast – for a cheesy flavor and added nutrition. Read my post about nutritional yeast if you want to know more.
  • Vegan Margarine – or vegan butter to add to the tofu to give the quiche richness, and to brush on the top to give it a shine. 
  • Soy Milk – or any plain flavored plant-based milk to thin out the tofu and make it into a very thick batter.  (The amount will vary depending on the firmness of your tofu).
  • Salt and pepper – to flavor the eggless quiche filling.
  • Vegan Cheese – you can use your favorite store-bought vegan cheese.  Traditional quiche Loraine calls for Swiss cheese.  If you want that classic taste, you can use my recipe for Vegan Swiss Cheese and make your own.  Vegan Mozzarella Cheese also works great in this recipe!
  • Oil – any neutral oil will work to saute the onions, mushrooms, and spinach.
  • Onion – for flavor.  You can leave them out if you don’t like them, but it adds a lot of flavor to the whole dish.
  • Mushrooms – for flavor and texture.  (optional but recommended).
  • Baby Spinach – for flavor, nutrition, and to lighten up the quiche. Fresh baby spinach has the best flavor and texture, but you can use frozen if you need to. (Massaged kale also works well).
  • Bacon Bits – or diced smart bacon for flavor.  (Most store-bought bacon bits are actually vegan or you can easily make your own vegan bacon bits with my recipe).  (This is also optional, but they give the quiche a nice smokey flavor).

Tools needed

  • Pie Dish – to bake your quiche
  • Food Processor – to blend your tofu and other ingredients. 
  • Large Skillet – for sauteing the onions, mushrooms, and kale and mix the quiche batter in.
  • Rubber Spatula – to scrape out the tofu mixture and press it into the pie crust. 
  • Kitchen Brush – to brush a little vegan margarine on the top after baking.

How to make vegan quiche Lorraine

Step 1 – Preheat your oven to 400°F (204°C).

Step 2 – Make a vegan pie crust or roll out a store-bought pie crust. Prepare the pre-made pie crust by lining the bottom of a pie dish with the pastry and crimping or fluting the edges. 

Cook the vegetables

Step 3 – Dice onion and saute it in a little oil over low heat until translucent. 

Step 4 – Add diced mushrooms sprinkle with a little salt and continue to saute until they begin to release their juices.

Step 5 – Add baby spinach and stir for a few minutes until the spinach just barely wilts.

Make the tofu mixture

Step 6 – Break up the tofu into smaller pieces so it fits in your food processor. (You may have to do this in 2 batches if you don’t have a large food processor).

Step 7 – Add salt, pepper, nutritional yeast, and melted margarine to your food processor and blend. (It will turn into a crumbly mixture).

Step 8 – Slowly add soy milk 1 tbsp at a time blending between each tbsp until the tofu mixture turns from crumbly to a very thick paste.

Step 9 – Add the tofu mixture to the sauteed veggies along with vegan cheese, and vegan bacon bits, and mix well.

Put it all together and bake

Step 10 – Pour the combined tofu-veggie mixture into your formed pie crust.

Step 11 – Pack the tofu down firmly and evenly in the pie dish.

Step 12 – Bake at 400°F (204°C) for 1 hour.

Step 13 – Brush the top of the quiche with an additional tbsp of melted margarine if desired for a shiny glow. 

Step 14 – Let it cool for about 10 minutes before cutting to allow it to set a little and firm up.

Pro Tips

  • Add just enough milk so the tofu is smooth and not grainy looking.  (This will be about 1/2 cup if using the high protein tofu, and only a tablespoon or 2 if using the extra firm tofu).
  • Allow the quiche to cool a little before slicing.  This helps it set up and come out in a nice solid piece. 

What type of tofu works best?

There are two types of tofu that work best for this recipe.  Dense, high protein, shrink-wrapped tofu or extra firm, water-packed tofu is usually sold in a plastic tub.  Both will work but the high-protein tofu is preferred if you can find it (Trader Joe’s carries it if you have one near you). 

The water-packed, extra-firm tofu will work but make sure to press it to squeeze out the water.  Once pressed, water-packed tofu also has slightly less weight so you will need 2 1/2 containers to equal 2 full pounds of tofu. You do not want to use silken tofu for this quiche recipe.

How to make crustless quiche muffins

If you want to omit the pie crust, you can.  This tofu quiche will bake up firm enough that you can get it out of the pie dish in one piece even without the crust.  You can also turn it into savory vegan muffins that are great for a grab-and-go breakfast.

What vegetables can I use?

Feel free to swap out the onion, mushrooms, and spinach with things like garlic, broccoli, kale, and bell peppers.  All of these veggies make for a delicious quiche.  I just always gravitate back to the onion, spinach, and mushrooms because it tastes like Betty Crocker’s Quiche Lorraine that I grew up eating.

Gluten-free instructions 

The filling is naturally gluten-free, so you only have to use a gluten-free pie crust to have a gluten-free quiche.  You may be able to find a pre-made one at a specialty store, but I highly recommend using my Gluten-Free Pie Crust Recipe that Works.  I spent years perfecting it and it really is the best gluten-free pie crust I’ve ever tasted!

Soy-free instructions 

If you want a soy-free version of vegan quiche, you can use my chickpea bread recipe as a filling for your quiche instead.  Add the veggies, vegan cheese, and bacon bits to the basic chickpea bread base and bake for 45 minutes at 400°F in the pie crust. Allow cooling for about 15 minutes before slicing.  This will be denser than tofu, but equally delicious! 

Note: To make this soy-free, you will also want to omit the bacon bits since they are made with dehydrated soy protein.

  • 2 cups diced mushrooms, (a 16 oz. container)
  • 1 5 oz. bag baby spinach
  • 2 (16 oz.) packages high protein tofu, or extra firm tofu
  • 1/4 cup melted margarine
  • 1/2 cup nutritional yeast
  • 2 teaspoons salt
  • 1/2 teaspoon black pepper
  • 1/4-1/2 cups plain soy milk, (or other plant-based milk)
  • 2/3 cup vegan cheese, shredded
  • 2/3 cup bacon bits
  • 1 tablespoon melted margarine , optional for brushing on the top after baking.

Equipment

Instructions
 

To make the hot water pie crust (use premade to skip this step)

  • Mix the dry ingredients (1 1/2 cups flour, 1/4 tsp baking soda, 3/4 tsp salt) in a bowl then pour in 1/2 cup oil and 3 tbsp boiling water. Mix well until it forms a ball.
  • Place the ball of dough on a piece of parchment paper and push it flat. Cover with the second piece of parchment paper.
  • Use a rolling pin to roll the dough flat between the parchment, then peel off the top sheet.  Use the bottom piece of parchment to help you flip the crust onto the pie dish and peel off the second piece of parchment. 
  • Pinch around the edges forming the pie crust into an even edge. 

Make the vegan quiche filling

  • Preheat your oven to 400°F (200°C).
  • Dice 1 medium onion and saute it in 1 tbsp of oil over low heat until translucent. 
  • Add 2 cups diced mushrooms sprinkle with 1/2 tsp salt and continue to saute until they begin to release their juices.
  • Add 5 oz of baby spinach and stir for a few minutes until the spinach just barely wilts, then turn off the heat.
  • Break up 2 packages of tofu into smaller pieces so it fits in your food processor. (You may have to do this in 2 batches if you don't have a large food processor).
  • Add 1/2 cup nutritional yeast, and 1/4 cup melted margarine, 2 tsp. salt, and 1/2 tsp pepper, to your food processor and blend. (It will turn into a crumbly grainy mixture).
  • Slowly add 1/4-1/2 cup soy milk, 1 tbsp at a time, blending between each tbsp until the tofu mixture turns from crumbly to a very thick paste. (If you don't use the high protein tofu, you may not need much milk).
  • Add the tofu mixture to the sauteed veggies along with 2/3 cup vegan cheese, and 2/3 cup vegan bacon bits. Mix well.
  • Pour the combined tofu-veggie mixture into your formed pie crust and pack the tofu down firmly and evenly in the pie dish.
  • Bake at 400°F (200°C) for 1 hour.
  • Brush the top of the quiche with an additional tbsp of melted margarine if desired for a shiny glow. 
  • Let it cool for about 10 minutes before cutting to allow it to set a little and firm up. 

Notes

  • This makes a large quiche!  It fills a 9-inch pie dish to the top.
  • If you are using a small ready-made pie crust, you may want to cut the recipe in half.
  • You can find packs of 2 ready-made vegan pie crusts in tins at most grocery stores.  This recipe fills those 2 ready-made crusts perfectly.
