Sun-dried Tomato, Mushroom, and Spinach Tofu Quiche

« Jump to Recipe »

tofuquiche-8641

As someone who works from home, I often need a nudge to be pulled away from my work; there aren’t as many opportunities for social connections (at least, in person) and that’s something I’ve missed since working for myself. I’m also a self-professed workaholic, always with fear in the back of my mind that if I’m not working all the time everything will somehow go to shit. Combine this mindset with loving what you do and it’s a recipe for not giving yourself much free time. I’m trying to work on this and create a better balance with it all, especially now that the majority of my book is complete. A change of pace is in order! Eric asked me the other night what my professional goals were for the next year and I’m still thinking about it, even toying with ideas like teaching vegan cooking classes, going back to school, and who knows what else. Or maybe I’ll just be content to keep things as is, but with more wiggle room to try new things. Half the fun is figuring it out, I guess.

Several months ago, one of my girlfriends organized a monthly meet-up inviting a group of friends who are all fellow entrepreneurs/business owners. I couldn’t say “count me in” fast enough, knowing it would be a great way to connect with other women who are balancing their businesses (with motherhood, for some), while facing many of the same questions and doubts that I’ve faced myself. In our group we have a photographer, an interior designer, a mortgage broker, an esthetician, a real estate agent, and me, the blogger/future cookbook author. They are all such amazing women and it’s a fun, random mix of experiences and talents. It’s been refreshing to share our struggles and victories together and I’ve even surprised myself at how much I needed this support system. Self-reliance has always been my strength (to a fault, perhaps), but there is no weakness in asking for help, support, or friendship. In fact, it’s quite the opposite.

This was my first time making a tofu quiche and it really surprised us with how amazing it turned out! Even Eric went crazy for this quiche, often enjoying leftovers twice a day until it was finished. Enjoy it for breakfast, lunch, dinner, or a snack. I've made this a few different ways simply by changing up the vegetables used. One version used asparagus (1 cup diced) and broccoli (1.5 cups diced), which was also very nice. The only thing I would advise against is using a high-water vegetable, like fresh tomatoes as it might result in a water-logged quiche. Best of all, it reheats well. Simply place leftover quiche on a baking sheet and pop it in the oven for 15-20 minutes at 350F. Inspired by the Sprouted Kitchen Cookbook.

Ingredients

For the crust:
  • 1 tablespoon ground flax + 3 tablespoons water, mixed together
  • 1 cup whole almonds, ground into flour
  • 1 cup gluten-free rolled oats or buckwheat groats, ground into flour
  • 1 teaspoon dried parsley
  • 1 teaspoon dried oregano
  • 1/2 tsp kosher salt
  • 1 tbsp coconut oil or olive oil
  • 1-2.5 tbsp water, as needed
For the quiche:
  • 1 block (14-oz) firm tofu
  • 1 tablespoon coconut oil or olive oil
  • 1 leek or yellow onion, thinly sliced
  • 3 large garlic cloves, minced
  • 3 cups (8-oz) sliced cremini mushrooms
  • 1/2 cup fresh chives, finely chopped
  • 1/2 cup fresh basil leaves, finely chopped
  • 1/3 cup oil-packed sun-dried tomatoes, finely chopped
  • 1 cup baby spinach
  • 2 tbsp nutritional yeast
  • 1 teaspoon dried oregano
  • 3/4-1 teaspoon fine grain sea salt
  • Black pepper, to taste
  • Red pepper flakes, to taste

Directions

  1. Preheat oven to 350F and lightly grease a round 10-inch tart pan. Alternatively, you can use a 9-inch glass pie dish if desired.
  2. Wrap rinsed tofu in a few tea towels. Place a few books on top of it to lightly press out the water while you prepare the crust.
  3. For the crust: Whisk together flax and water mixture in a small bowl and set aside so it can gel up.
  4. In a large bowl, stir together the almond meal, oat flour (or buckwheat flour), parsley, oregano, and salt.
  5. Add in the flax mixture and oil. Stir until mostly combined, adding the remaining water until the dough is sticky (about the consistency of cookie dough). The dough should stick together when you press it between your fingers.
  6. Crumble the dough evenly over the base of the tart pan (or pie dish). Starting from the centre of the pan, press the mixture evenly into the pan, working your way outward and up the sides of the pan. Poke a few fork holes in the dough so air can escape.
  7. Bake the crust at 350F for 13-16 minutes, or until lightly golden and firm to touch. Set aside to cool while you finish preparing the filling. Increase oven temperature to 375F.
  8. For the filling: Break apart the tofu block into 4 pieces and add into food processor. Process the tofu until smooth and creamy. If it doesn't get creamy, add a tiny splash of almond milk to help it along.
  9. In a skillet, add oil and saute the leek (or onion) and garlic over medium heat for a few minutes. Stir in the mushrooms, season with salt, and cook on medium-high heat until most of the water cooks off the mushrooms, about 10-12 minutes. Stir in the herbs, sun-dried tomatoes, spinach, nutritional yeast, oregano, salt, pepper, and red pepper flakes until combined. Cook until the spinach is wilted.
  10. Finally, remove from heat and stir in the processed tofu until thoroughly combined. Adjust seasoning to taste if desired. Spoon mixture into baked crust and smooth out with a spoon until even.
  11. Bake quiche, uncovered, at 375F for 33-37 minutes, until the quiche is firm to the touch. For best results, cool the quiche for 15-20 minutes on a cooling rack before attempting to slice. The crust may crumble slightly when sliced warm, but not to worry.
  12. Wrap up leftovers and refrigerate for 3-4 days. Leftover quiche can be reheated in the oven on a baking sheet for about 15-20 minutes at 350F.

Do you have a crust recipe that uses whole wheat flour or could I just sub the almond flour for 1/3 cups whole wheat? Thanks :)

Hi Angela, it looks fantastic! I’ve just put the quiche in the oven. I’m absolutely sure it’s going to be as tasty as it looks. I’ll tell you later :-)) Anyway, how much do you mean when you say “a cup” in your recipes? I guess it would help… But the pastry turned out well, even with “my size” of a cup :-)

Angela,
This taste’s fantastic! So good! We started a little vegan food swap in our neighborhood where we all make a dish, divvy it up into single size portions and swap with each other. We end up having 5-6 vegan dishes to try for lunch each week. I just wanted to tell you that you have become our go to site for all things delicious! I can honestly say that everything I’ve made or tasted from your site has been heavenly. THANK YOU!

I just made this quiche for the first time. I love quiche and was worried that this one wouldn’t begin to compare to the “real” thing. Boy, was I wrong! This quiche is amazing!

Hi Andrea, I’m sorry but I’m not sure – I haven’t tried it any other way yet. Might be worth a try! Let me know if you test one.

Now I’m not sure what I will do! The crust just sounds too yummy. I don’t have a food processor yet so I was thinking of saving the money on almond flour. I’ll let you know!

Made this tofu quiche for a work potluck. It was a hit! I will definitely make this again; planning on it for Christmas morning :)

It looks great.. I just wish it was not “Gluten-free”. The Gluten free trend is great for 1% of Americans with Celiac disease, but for those without its kind of pointless and does not offer any nutritional benefit. It’s just a popular trend at the moment..

“Gluten Free” is not a trend. More & more people are becoming Gluten Sensitive due to the Genetic Modification of so many foods. Many people who have Fibromyalgia & Arthritis are even finding that bu cutting back on Gluten, they have less pain. Not only is this crust Gluten Free but is so much healthier than any crust I have had. It is delicious. I will use it in other recipes besides Quiche.

Just made this quiche, followed recipe to a tee, except I also added a handful of minced kalamata olives. Results: complete success. I plan to bake up a few of these at a time to freeze for separate meals. Thanks so much for such a winner of a recipe!

Can the flax + water be substituted by 1 egg? I ask because I do eat eggs, and have everything on-hand to make this meal EXCEPT flax. It looks SO good :)

I just made this for brunch. It was SO delicious. I have three kids: a 3 1/2 year old, 2 1/2 year old and an one year old and even they gobbled it up! We didnt miss the eggs one bit. The only thing I changed was kale instead of spinach and my own vegan pie crust recipe. Thank you Angela for this recipe and introducing my family to delicious vegan recipes.

My kiddos are allergic to soy. What would be a good alternative to tofu. Would white beans, cauliflower, or coconut, even be an option? I really miss my quiche! TIA

This recipe is seriously delicious. The herbs in the crust give a significant punch of flavour and while I was a bit hesitant to make a tofu quiche, it didn’t last long and I am craving it again already. Thx!

I notice many of your recipes have nuts and/or seeds. My children have severe food allergies. Do you have any substitution ideas when your recipes call for these common allergy foods?

I used buckwheat flour for the crust instead of oats. Didn’t use fresh basil or chives. Added some diced goat cheese instead of the nutritional yeast. And used kale instead of spinach. One of the most delicious things I’ve ever eaten!

Made this for dinner tonight…. Oh my! It was delicious!
I replaced the almonds for raw cashews.
At first, the crust seemed a little to crunchy, but in combination with the filling, it turned out amazing! Even my 2- & 4 year old kids ate their ‘pie’ just like that! :-)
Thank you!!
