This Vegan Cheesy Potato & Spinach Quiche is creamy, savory, satisfying, and packed with tender potatoes, fresh spinach, and dairy-free cheesy flavor. Skipping the crust makes the recipe simpler while letting the soft potato and spinach filling take center stage.

A blend of silken tofu, nutritional yeast, plant-based cheese, and seasonings creates a rich, custardy texture without eggs or dairy. It’s an easy vegan breakfast, brunch, lunch, or light dinner that feels comforting while still featuring plenty of wholesome vegetables.

Can This Vegan Cheesy Potato & Spinach Quiche Support Weight Loss Goals?

This crustless quiche can fit into a balanced eating pattern because it provides vegetables and plant-based protein without the extra calories of a traditional pastry crust. Potatoes provide satisfying carbohydrates, while tofu contributes protein that helps make the dish more substantial. Portion size and the amount of vegan cheese and oil used will influence the overall calorie content, so those ingredients can be adjusted according to your personal needs.

Does This Recipe Fit a High-Protein Lifestyle?

This quiche provides a moderate amount of plant-based protein primarily from silken tofu and nutritional yeast. It is not intended to be an exceptionally high-protein recipe, but it can work well within a protein-conscious vegan meal. The potatoes contribute carbohydrates, while spinach and tofu add fiber, protein, and micronutrients. For a higher-protein meal, serve it with a side of seasoned beans or a tofu-based salad.

Common Mistakes to Avoid

Adding watery spinach: Excess moisture can make the filling too wet. Cook fresh spinach briefly and squeeze or drain it well.
Using large raw potato pieces: Thick chunks may remain firm while the quiche sets, so dice the potatoes into small pieces and cook them first.
Overfilling the baking dish: Too much filling can increase the baking time and make the center difficult to set.
Slicing immediately: Allow the quiche to rest for at least 10–15 minutes after baking so the filling can firm up.

Required Equipment

9-inch pie dish — provides the right depth and surface area for even baking.
Blender or food processor — creates a smooth, creamy tofu-based filling.
Large mixing bowl — gives enough space to combine the filling and vegetables.
Skillet — quickly cooks the potatoes and wilts the spinach before baking.
Rubber spatula — helps fold the vegetables into the creamy mixture gently.
Sharp knife — makes it easy to dice potatoes evenly.
Wire rack — allows the baked quiche to cool evenly before slicing.

Storage Instructions

Let the quiche cool completely before storing.

Refrigerator: Place individual slices in an airtight container and refrigerate for up to 4 days.
Freezer: Wrap individual slices tightly and place them in a freezer-safe container or bag for up to 2 months.
Best meal-prep method: Store individual portions separately so you can reheat only what you need.
Reheating: Microwave a slice for about 60–90 seconds, or warm it in a 350°F (175°C) oven for 10–15 minutes until heated through.
Texture note: Oven reheating generally preserves the firmer texture better than microwaving.
Proper storage does not remove the plant-based protein from the tofu, although the exact nutritional value depends on the brands and ingredients used.

📝 Ingredients

For the Potato & Spinach Filling

1 ½ cups (225 g) potatoes, peeled and diced small — Yukon Gold potatoes work especially well.
2 cups (60 g) fresh baby spinach — roughly chop if the leaves are large.
1 tablespoon olive oil — for sautéing.
½ cup (75 g) finely diced yellow onion — adds sweetness and savory depth.
2 cloves garlic, minced — adds aromatic flavor.
¼ teaspoon fine salt — for cooking the vegetables.
¼ teaspoon freshly ground black pepper — adds gentle warmth.

For the Vegan Quiche Base

14 oz (397 g) silken tofu, drained — creates the creamy, egg-free custard.
½ cup (60 g) shredded vegan cheese — use cheddar-style or mozzarella-style vegan cheese.
¼ cup (15 g) nutritional yeast — adds savory, cheesy flavor.
2 tablespoons unsweetened plant milk — helps the filling blend smoothly.
1 tablespoon cornstarch — helps the quiche set.
1 teaspoon Dijon mustard — adds savory tang.
½ teaspoon turmeric — optional, mainly for warm color.
½ teaspoon onion powder — enhances the savory flavor.
½ teaspoon garlic powder — adds extra depth.
¼ teaspoon smoked paprika — provides subtle smoky warmth.
¼ teaspoon black salt (kala namak) — optional; gives an egg-like savory note.

Ingredient Note

Use firm silken tofu, not extra-firm tofu, for the smoothest custard-like texture. If your vegan cheese is already quite salty, reduce the added salt slightly.

Directions

Preheat the oven.
Heat the oven to 375°F (190°C). Lightly grease a 9-inch pie dish or similar baking dish.
Cook the potatoes.
Heat olive oil in a skillet over medium heat. Add the diced potatoes and cook for approximately 8–10 minutes, stirring occasionally, until they are beginning to soften and develop lightly golden edges.
Add the onion and garlic.
Add the diced onion and cook for 3–4 minutes until softened. Add the minced garlic and cook for another 30–60 seconds, just until fragrant.
Wilt the spinach.
Add the spinach, salt, and black pepper. Cook for 1–2 minutes, stirring, until the spinach is wilted. Remove from the heat and drain any excess moisture.
Blend the quiche base.
Add drained silken tofu, vegan cheese, nutritional yeast, plant milk, cornstarch, Dijon mustard, turmeric, onion powder, garlic powder, smoked paprika, and optional black salt to a blender.
Blend until smooth.
Process for approximately 30–60 seconds, scraping down the sides if necessary. The mixture should be thick, creamy, and smooth.
Combine the filling.
Transfer the blended tofu mixture to a bowl. Fold in the cooked potatoes, spinach, onion, and garlic until evenly distributed.
Fill the dish.
Spoon the mixture into the prepared pie dish and spread the top evenly with a spatula.
Bake.
Place in the 375°F (190°C) oven and bake for 35–40 minutes. The edges should look set, the surface should be lightly golden, and the center should have only a slight wobble.
Rest before slicing.
Remove from the oven and allow the quiche to rest for 10–15 minutes. This gives the tofu-based filling time to firm up.
Serve.
Slice into 6 portions and serve warm or at room temperature.

Vegan Cooking Tip

For the best texture, avoid adding spinach directly to the raw filling. Cooking and draining it first removes excess moisture and helps the finished quiche set properly.

Notes

For a firmer quiche: Allow the baked quiche to rest for the full 15 minutes before cutting.
For extra cheesiness: Sprinkle an additional 2 tablespoons of vegan cheese over the top before baking.
For more vegetables: Add finely chopped mushrooms, bell peppers, or broccoli after cooking them until their excess moisture has evaporated.
For a spicy version: Add a pinch of red pepper flakes or finely chopped jalapeño.
For extra flavor: Fresh thyme, parsley, chives, or basil can be folded into the filling.
Allergy note: Vegan cheese and plant milk may contain soy, nuts, coconut, or other allergens. Check product labels according to your dietary needs.
Gluten-free: The basic recipe can be gluten-free, but check all packaged ingredients for gluten or cross-contact.
Reheating: For the best texture, reheat individual slices in a 350°F (175°C) oven rather than overheating them in the microwave.
Serving idea: Pair with a simple green salad, roasted tomatoes, or fresh fruit for a balanced vegan meal.

Frequently Asked Questions

1. Can I make this quiche without vegan cheese?

3. Do I need to boil the potatoes first?
No, but the potatoes should be diced small and sautéed until partially tender before they go into the quiche.

4. Why does my vegan quiche need to rest after baking?
Resting allows the tofu-based filling to firm up so the slices hold together more cleanly.

6. Can I add other vegetables?
