Description
This Vegan Classic Spinach & Mushroom Crustless Quiche is creamy, savory, and packed with tender spinach, earthy mushrooms, and flavorful herbs in every bite. Without a traditional pastry crust, it keeps the dish lighter while still delivering a satisfying, comforting texture. Silken tofu creates a smooth, protein-rich base, while nutritional yeast adds a delicious savory depth. It is an excellent choice for anyone looking for a high-protein vegan meal, a lower-carb breakfast, or an easy make-ahead dish for busy days.
Can This Vegan Classic Spinach & Mushroom Crustless Quiche Support Weight Loss Goals?
This quiche can fit into a balanced weight-management eating pattern because it combines plant-based protein from tofu with fiber-rich vegetables while skipping the traditional pastry crust. The combination can make a meal more filling than a vegetable-only dish, while portion size and the overall ingredients still determine the calorie content. Pairing a serving with a fresh salad or additional vegetables can create a balanced, protein-focused meal.
Does Vegan Classic Spinach & Mushroom Crustless Quiche Fit a High-Protein Lifestyle?
Yes, this crustless quiche can work well in a high-protein vegan lifestyle because silken tofu provides the main protein source without using eggs or dairy. Spinach and mushrooms add volume, micronutrients, and fiber while keeping the recipe relatively moderate in net carbs. Nutritional yeast contributes additional protein and a savory, cheesy-style flavor. For an even higher-protein meal, serve it alongside edamame, a lentil salad, or another plant-based protein source.

My Personal Experience

Sautéing the mushrooms before baking gives them a deeper, more savory flavor.
Their tender texture works beautifully with the creamy tofu-based filling. - I loved how satisfying the crustless texture felt:
Even without pastry, the quiche still feels like a complete comfort-food meal.
The tofu filling becomes firm enough to slice while remaining pleasantly soft inside. - The spinach adds freshness and color:
Wilted spinach blends naturally into the filling without overpowering the mushrooms.
It also makes every slice look vibrant and inviting. - It is especially convenient for meal prep:
The slices can be refrigerated and reheated when you need a quick breakfast or lunch.
That makes this recipe much easier to fit into a busy weekly routine.

Common Mistakes to Avoid
- Skipping the mushroom sauté: Raw mushrooms release water during baking and can make the filling watery. Cook them until their excess moisture has evaporated first.
- Adding wet spinach: Excess moisture from spinach can prevent the quiche from setting properly. Squeeze or drain cooked spinach thoroughly before adding it.
- Over-blending the vegetables: Blend the tofu base until smooth, but keep the mushrooms and spinach separate so the finished quiche has some texture.
- Slicing too soon: Allow the quiche to rest after baking so the filling can finish setting and produce cleaner slices.
Required Equipment
- Non-stick skillet: Helps sauté mushrooms and spinach without excessive sticking.
- Blender or food processor: Creates a smooth, creamy tofu filling.
- 9-inch pie dish: Provides an ideal shape and depth for even baking.
- Mixing spatula: Makes folding the vegetables into the tofu mixture easy.
- Sharp knife: Helps produce neat slices after the quiche has rested.
Storage Instructions
Allow the quiche to cool completely before storing. Place individual slices in airtight containers or wrap the entire quiche tightly and refrigerate for up to 4 days.
For longer storage, wrap individual slices in freezer-safe material and place them in a sealed freezer bag or container. Freeze for up to 2 months for best texture.
To reheat, place a slice in a 325°F (165°C) oven for approximately 10–15 minutes, or warm it gently in a covered skillet. Microwave reheating also works, but short intervals help prevent the tofu filling from becoming rubbery.

Short 3-Line Description
This Vegan Spinach & Mushroom Crustless Quiche is creamy, savory, and packed with plant-based protein.
Silken tofu, mushrooms, spinach, and nutritional yeast create a satisfying egg-free filling without a pastry crust.
It is an easy lower-carb option for vegan breakfasts, lunches, meal prep, or light dinners.
📝 Ingredients
- 14 oz (397 g) silken tofu, drained
- 2 cups fresh spinach, chopped
- 1½ cups mushrooms, thinly sliced
- ½ medium yellow onion, finely diced
- 2 cloves garlic, minced
- ¼ cup nutritional yeast
- 2 tablespoons unsweetened plant-based milk
- 1 tablespoon olive oil
- 1 tablespoon cornstarch
- ½ teaspoon turmeric
- ½ teaspoon dried thyme
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- ½ teaspoon salt
- 1 tablespoon chopped fresh parsley, optional
Ingredient note: Use unsweetened plant milk so the filling remains savory. Firm silken tofu works particularly well because it blends smoothly while providing a substantial plant-based protein base.
Directions
- Preheat the oven:
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish with a small amount of olive oil. - Sauté the mushrooms:
Heat 1 tablespoon olive oil in a skillet over medium heat. Add the diced onion and mushrooms and cook for 5–6 minutes, stirring occasionally. - Add the garlic and spinach:
Add the minced garlic and cook for about 30 seconds. Add the spinach and cook for another 1–2 minutes, just until wilted. - Remove excess moisture:
Continue cooking briefly if the mushroom mixture looks watery. The vegetables should appear tender and relatively dry before going into the filling. - Blend the tofu mixture:
Add the drained tofu, plant milk, nutritional yeast, cornstarch, turmeric, thyme, onion powder, salt, and black pepper to a blender. Blend until completely smooth and creamy. - Combine the filling:
Transfer the tofu mixture to a bowl and fold in the sautéed mushrooms, onion, garlic, and spinach. Stir gently so the vegetables remain distributed throughout the filling. - Fill the pie dish:
Pour the mixture into the prepared dish and spread the surface evenly with a spatula. Sprinkle fresh parsley over the top if desired. - Bake:
Place the dish in the preheated oven and bake at 375°F (190°C) for 35–40 minutes. The center should look set with a slight firmness when gently touched. - Rest:
Remove the quiche from the oven and allow it to cool for 10–15 minutes. This resting period helps the filling firm up for easier slicing. - Serve:
Slice into 6 portions and serve warm or at room temperature. For an extra protein boost, pair it with edamame, lentils, or another plant-based protein.
High-protein cooking tip: Use a tofu variety with a higher protein content when available and pair the quiche with another plant-based protein source if you want a more protein-dense meal.

Notes
- Storage: Refrigerate leftovers in airtight containers for up to 4 days or freeze individual slices for up to 2 months.
