My grandmother’s quiche was a thing of beauty, all wobbly custard and flaky, golden crust. For years, I thought a vegan version was a culinary pipe dream—a sad, crumbly imitation of the real thing. Oh, how wrong I was. The breakthrough happened, as it often does in my kitchen, out of sheer desperation and a near-empty fridge. I had a block of silken tofu that needed using, and a pie crust in the freezer. What emerged from the oven that day was nothing short of a miracle. It was creamy, it was firm, it was… perfect. My husband, a devout carnivore, took one bite and said, “Wait, this is vegan?” with a look of pure betrayal. That’s when I knew I had to share it.

Grab These
- For the Crust:
- 1 store-bought vegan pie crust (I swear by Wholly Wholesome brand) or your favorite homemade recipe
- For the Filling:
- 1 (12-14 oz) block firm or extra-firm silken tofu, drained (don’t use the regular firm tofu in the water-filled tub! It’s too grainy. The silken kind in the shelf-stable box is key.)
- ¼ cup unsweetened, unflavored plant-based milk (oat milk is my go-to for its neutral creaminess)
- 3 tablespoons nutritional yeast (this is your “cheesy” flavor secret weapon!)
- 2 tablespoons all-purpose flour or chickpea flour
- 1 tablespoon fresh lemon juice
- 1 teaspoon onion powder
- ½ teaspoon garlic powder
- 1 teaspoon fine sea salt
- ½ teaspoon turmeric (mostly for that gorgeous golden color)
- ¼ teaspoon black salt (Kala Namak) – This is NON-NEGOTIABLE. It gives that sulfurous, eggy flavor. Find it at any Indian grocery or online.
- ¼ teaspoon black pepper
- For the Add-Ins (use about 1 ½ cups total):
- 1 tablespoon olive oil
- 1 small onion, diced
- 2 cups sliced cremini mushrooms
- 1 cup chopped spinach or kale
- 2 cloves garlic, minced
Let’s Make It
First things first, let’s talk crust. If you’re using a frozen one, let it thaw just enough that you can prick the bottom and sides all over with a fork. This, my friends, is called “docking,” and it prevents the crust from puffing up into a giant bubble while it bakes blind. Pop it into a 375°F (190°C) oven for about 10-12 minutes, just until it’s starting to look dry and ever so slightly golden. We’re not cooking it all the way through, just giving it a head start.
While that’s happening, let’s get our filling going. Heat the olive oil in a skillet over medium heat. Toss in your diced onion and mushrooms with a pinch of salt. We’re not just wilting them here; we’re trying to get some good color and cook out all that moisture. Soggy veggies = soggy quiche. Nobody wants that. When they’re nicely browned and fragrant, stir in the garlic and spinach just until the spinach wilts, about a minute. Take it off the heat and let it cool a bit.
Now, for the magic. In a blender, and I mean a good blender (this is where my Vitamix earns its counter space), combine the silken tofu, plant milk, nutritional yeast, flour, lemon juice, and all those spices—including that all-important black salt. Now, blend. I’m talking blend for a full minute, maybe two. You want this to be utterly smooth. No graininess, no little tofu bits. It should look like a thick, pourable, sunshine-yellow custard. Taste it! This is the crucial step. Adjust the salt and pepper. Does it taste eggy enough for you? If not, maybe another tiny pinch of black salt. It should taste delicious even now.
Pour that beautiful, smooth custard into a bowl and stir in your sautéed veggie mixture. Take your par-baked crust out of the oven (careful, the pan is hot!). Give the filling one more stir and pour it all into the crust, spreading it out evenly. It should come right up to the top.
Slide it back into the oven and bake for 40-50 minutes. You’re looking for the top to be lightly golden and, most importantly, for the center to be set. It might have a slight jiggle, but it shouldn’t look wet or liquidy. Let it cool on a wire rack for at least 20 minutes before you even think about slicing into it. I know, the wait is torture. But it needs this time to firm up properly. It’s a lesson in patience I’m still learning.

Variations & Add-Ins
- ‘Bacon’ & Leek: Sauté one thinly sliced leek until soft, then stir in ½ cup of crumbled vegan bacon (my favorite is the coconut bacon you can make at home – it’s shockingly good) along with the other veggies.
- Sun-Dried Tomato & Basil: Swap the mushrooms for ½ cup of chopped sun-dried tomatoes (the oil-packed kind, drained) and stir in ¼ cup of fresh chopped basil at the very end, right before pouring into the crust.
- Broccoli Cheddar: Use 1 ½ cups of small broccoli florets instead of the mushroom/spinach mix. For extra cheesy flavor, add ⅓ cup of shredded vegan cheddar cheese to the blender with the tofu mixture.
Serving Ideas
- “This is my ultimate brunch centerpiece. I serve it with a simple arugula salad dressed with lemon vinaigrette and a big platter of fresh fruit.”
- “For a cozy dinner, it’s fantastic with a cup of tomato soup for dipping. Don’t knock it ’til you’ve tried it.”
- “My daughter loves a cold slice straight from the fridge, wrapped in a napkin, as she runs out the door. A win is a win.”
Storage & Reheating
- “Let the quiche cool completely, then cover the whole pie plate with plastic wrap or transfer slices to an airtight container. It will keep beautifully in the fridge for 3-4 days.”
- “To reheat, I strongly advise against the microwave unless you want a rubbery texture. Place a slice on a baking sheet in a 350°F (175°C) oven for 10-15 minutes, until warmed through. It restores the crust’s flakiness, too.”
- “You can also freeze the whole quiche or individual slices for up to 2 months. Thaw in the fridge overnight before reheating.”
My Two Cents (Pro-Tip)
That black salt (Kala Namak). I’m going to say it again. It’s the single ingredient that transforms this from a “nice tofu bake” into a “is-this-really-vegan?” quiche. It smells strongly of hard-boiled eggs when you open the jar, but once blended in, it performs pure magic. Don’t skip it. You can find it online for a few dollars.
You Asked, I’m Answering (FAQ)
- “My filling turned out a bit wet. What did I do wrong?” The most common culprit is not cooking the vegetables enough before adding them. You really have to drive off all that excess moisture in the mushrooms and onions. Another tip is to make sure you’re using silken tofu, not the regular kind, which has more water.
- “Can I make this without a blender?” Honestly? No. I’ve tried with a food processor and even with a vigorous whisking arm, and it just doesn’t get smooth enough. The blender is essential for that signature custardy texture.
- “I can’t find black salt. Is there a substitute?” You can make it without, and it will still be a lovely, savory tart. But it just won’t have that distinctive “eggy” flavor. In a pinch, add an extra tablespoon of nutritional yeast and a squeeze more of lemon juice to boost the savory notes.
