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:

  • ¾ cup (0.75 g) plus 2 tablespoons flour I use all-purpose. You can also use oat flour to make it gluten-free.
  • ¾ cup (85 g) plus 2 tablespoons, almond flour
  • ½ teaspoon salt
  • 2 teaspoons flaxseed meal mixed with 2 tablespoons of water
  • ½ teaspoon oregano
  • ¼ 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
  • ¼ teaspoon black pepper
  • ½ teaspoon Indian Sulfur salt or Kala Namak
  • ½ teaspoon salt
  • ½ teaspoon turmeric
  • ¼ teaspoon baking powder
  • ½ 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
  • ¾ cup chopped leeks
  • 1 cup thinly sliced mushrooms
  • ¼ tsp salt
  • ¾ 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

How to store leftover quiche

Keep the whole quiche or any leftover slices covered in the fridge and eat within 3 to 4 days. The vegan quiche is delicious served warm or cold. I often eat it straight from the fridge.

FAQs

Should you saute veggies before adding to quiche? ›

Cook the Veggies First

"Vegetables will take longer to cook than your egg custard, so always sauté onions, steam broccoli, etc. before you add them to your egg mixture to ensure every bite of quiche will be perfectly cooked," says Kristin Beringson, executive chef at Henley in Nashville.

How do you make a quiche without a soggy bottom? ›

If you pour the egg custard into an unbaked crust, the liquid is unfortunately going to seep into the crust, preventing it from crisping up. The simple solution is to blind-bake the crust before adding the custard. Follow This Tip: Blind-bake the pie crust before pouring in the custard to ensure a crisp, flaky crust.

Why is my quiche not fluffy? ›

You want to cook your quiche low and slow to keep the light fluffy texture. Too high of heat will cause the egg to curdle.

Why do you put flour in quiche? ›

Roll it out a tad bit thicker than you normally would for a standard pie if possible, and absolutely use it all. Confidently press any overhang or extra pieces into the walls of your pan. Add flour to your filling: Adding a bit of flour to your quiche filling helps absorb moisture and stabilize things in general.

Should quiche be cooked at 350 or 375? ›

BAKE in center of 375°F oven until center is almost set but jiggles slightly when dish is gently shaken and knife inserted near center comes out clean, 30 to 40 minutes.

Should you Prebake crust for quiche? ›

And yes, as you'll see, you should always prebake quiche crust to avoid a gummy pastry. Preheat the oven to 450°F. Roll out your homemade or purchased refrigerated dough into a 12-inch circle.

What is the best cheese to use for quiche? ›

Cheese: Some favorites include feta cheese, goat cheese, cheddar cheese, white cheddar cheese, Swiss cheese, and gruyere. Add-Ins: Add up to 2 cups add-ins including vegetables and meat/seafood. Most quiche add-ins should be pre-cooked and can still be warm when mixing into the egg filling.

What is the formula for quiche? ›

Ratios: The best way to make a quiche is to add the eggs to a large measuring cup, then add the cream or milk. For every egg used you should add enough milk or cream to create a 1/2 cup. Meaning for 1 egg you will add enough cream or milk to make 1/2 a cup of mixture.

Why does my quiche sink when I take it out of the oven? ›

Excess moisture is one reason why quiches collapse in a watery pool on your plate. Vegetables and meats like ham give off tremendous amounts of water when they're cooked. Therefore, if you're using vegetables in your quiche, it's imperative that you cook them first.

Can you put too many eggs in a quiche? ›

The Kitchn cautions that using too many eggs can make the consistency of the quiche rubbery and tough, while using too few eggs can prevent the custard filling from setting properly, giving you a runny, soggy quiche. The recommended proportion is one egg to one-half cup of cream or milk.

What is the ratio of eggs to milk in a quiche? ›

Quiche Ratio: 1 large egg to 1/2 cup of dairy

You'll need to increase the amount of eggs and milk based on the size of your quiche, so knowing the basic ratio makes it really easy to scale up or down. For a standard 9-inch quiche: Use 3 large eggs (6 ounces) 1 1/2 cups of whole milk or cream (12 ounces)

Why put nutmeg in quiche? ›

Salt, cayenne pepper, ground nutmeg: These seasonings flavor of the quiche, with salt balancing the flavors, cayenne pepper adding a slight heat, and ground nutmeg providing a warm, nutty undertone.

Can you substitute almond milk for heavy cream in quiche? ›

Eggs: the base of any quiche is eggs, so we're keeping things traditional there. Almond milk: instead of cream/milk, we're swapping with unsweetened almond milk. I think you could also add a bit of cashew cream if you're wanting to make it a tiny bit richer.

Can I use milk instead of cream in my quiche? ›

While it is not as traditional for quiches such as quiche Lorraine, you can use milk instead of heavy cream for quiche. While the results are not *as* rich as if heavy cream is used, I find that by the time you factor in the cheese and eggs, the quiche is not at all lacking in indulgence.

How do you jazz up a quiche? ›

Choose ingredients with lots of flavour and combine them with seasonal vegetables: onions, mushrooms, spinach and chard, leeks, candied or dried tomatoes... you have an infinite number of combinations that make quiche a pleasure that can be renewed without tiring.

Should you sauté vegetables before making stock? ›

Cooking the vegetables before simmering can bring out more flavor along with additional sweetness. This can be done either by sweating or sauteing them in oil or by roasting them in a hot oven. Browning the vegetables also makes the finished stock darker.

Do you cook vegetables before blending? ›

Before you can begin blending your puree, you need to soften any hard produce. Wash and cut up your fruits and vegetables, removing any stems, skins or inedible seeds. Steam, roast or sautee your fruits and vegetables using your preferred technique.

Should I sauté veggies before adding to pasta sauce? ›

Dice up some vegetables and sauté them in a little oil before adding the sauce. Onions, peppers, carrots and garlic are all good, but you can throw in pretty much anything you like. The key is to have some kind of fresh vegetable to make it taste and look like fresh homemade sauce.

Is it better to roast or sauté vegetables? ›

In my (humble) opinion, the best method for cooking vegetables is to roast them. From Balsamic & Parmesan Roasted Broccoli to Garlic & Parmesan Roasted Carrots, roasting vegetables is an easy process that yields deliciously crispy results. Plus, roasting requires minimal hands-on effort (and who doesn't love that?).
