Ingredients
You don’t need too much to create this unctuous quiche. Here is the full list of ingredients you’ll require:
For the crust:
- 1 vegan pie crust (store-bought or homemade)
For the filling:
- 1 block (14 oz) silken tofu
- ½ cup unsweetened plant-based milk (almond, soy, or oat)
- 2 tablespoons nutritional yeast
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon turmeric (for color)
- 1 teaspoon salt
- ½ teaspoon black pepper
For the vegetables:
- 1 cup mushrooms, sliced
- 2 cups fresh spinach, roughly chopped
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 tablespoon olive oil (for sautéing)
For garnish:
- Fresh rosemary sprigs
- Fresh thyme leaves
- Ground black pepper
Instructions
This might not be the most straightforward recipe you’ve ever come across but it won’t take too long:
- Prepare the crust:
Preheat your oven to 375°F (190°C). Roll out your vegan pie crust and press it into a greased pie dish. Use a fork to prick the bottom of the crust to prevent air bubbles and pre-bake for 10 minutes. This step ensures a beautifully crisp and golden base for your quiche. - Sauté the vegetables:
In a skillet, heat olive oil over medium heat. Add diced onions and cook until translucent, about 3-4 minutes, allowing their natural sweetness to develop. Stir in the minced garlic and cook for an additional minute until fragrant and golden. Add the mushrooms and cook until tender and lightly browned, then stir in the spinach and cook until just wilted. Remove from heat and set aside to cool slightly. - Make the filling:
In a blender, combine silken tofu, plant-based milk, nutritional yeast, olive oil, garlic powder, onion powder, turmeric, salt, and black pepper. Blend until smooth and creamy, ensuring the mixture has a custard-like consistency for the perfect creamy filling. - Combine filling and vegetables:
Gently stir the sautéed vegetables into the tofu mixture until evenly distributed. Pour the filling into the pre-baked pie crust, smoothing the top with a spatula for an even finish. Add a few extra mushroom slices on top for visual appeal. - Bake the quiche:
Place the quiche in the oven and bake for 35-40 minutes, or until the filling is firm and the top is lightly golden. Let cool for at least 10 minutes before slicing to allow the filling to set fully and achieve clean, neat slices. - Garnish and serve:
Top with fresh rosemary sprigs, thyme leaves, and a sprinkle of black pepper. Serve warm or at room temperature, paired with a crisp green salad or roasted vegetables for a well-rounded meal.
Tweaks and Additions
The good news is that you can tweak and pimp this quiche to create lots of different dishes. Here are some ideas:
- Cheesy boost:
Add vegan cheese shreds into the filling for an extra layer of creaminess and that indulgent cheesy flavor. A sprinkle of vegan parmesan on top before baking adds a beautifully golden crust. - Herb infusion:
Fresh basil, parsley, or dill can elevate the flavor profile, enhancing the natural freshness of the spinach and adding aromatic depth to each bite. - Veggie swap:
For a Mediterranean twist, swap the mushrooms for sun-dried tomatoes, roasted zucchini, or bell peppers. These substitutions add bursts of sweetness and tangy richness, making each slice even more flavorful. - Crustless option:
For a low-carb, gluten-free version, skip the crust entirely. Pour the filling directly into a greased baking dish and bake until firm for a lighter yet equally satisfying option. - Spicy kick:
A pinch of red pepper flakes or a dash of hot sauce mixed into the filling brings a subtle heat, balancing the creamy richness with a lively, spicy edge. - Smoky depth:
Add a teaspoon of smoked paprika for a gentle smoky flavor that complements the earthy mushrooms beautifully.

This Vegan Mushroom and Spinach Quiche is elegant, creamy, and packed with flavor—perfect for brunch spreads, meal prepping, or simply enjoying a slice of plant-based comfort food.
It’s a dish that not only showcases how indulgent vegan cooking can be but also brings people together over nourishing, hearty flavors.
Whether served warm or cold, each slice is a reminder that compassionate cooking can be just as luxurious and satisfying as any traditional recipe.
