Potato Crust Mung Bean Quiche Ingredients
For the Potato Crust
• Potatoes (1.5 – 2 pounds) – Provides the base crust for the quiche; experiment with different potato varieties for unique flavors.
• Avocado Oil Spray – Used for greasing the baking dish; olive oil can also be an alternative.
• Salt and Pepper – Essential for seasoning, enhancing the overall flavor of the crust.
For the Filling
• Carrots (1 orange, 1 yellow, 1 purple) – Adds color and sweetness; substitute with regular carrots if rainbow varieties are unavailable.
• Fresh Spinach (1 bunch) – Offers freshness and nutrients; any leafy green like kale or swiss chard can work as an alternative.
• Sweet Onion (1/2, thinly sliced) – Contributes sweetness when caramelized; shallots can be swapped for a different flavor profile.
• Mushrooms (8 oz, shiitake, oyster, cremini) – Adds umami depth; feel free to use any mushrooms based on preference or availability.
• Soy Sauce (1 tablespoon) & Coconut Amino (1/2 tablespoon) – Enhances flavor; tamari can be used for a gluten-free option.
• Oregano (1/2 teaspoon) – Provides herbal notes; substitute with Italian seasoning if preferred.
For the Mung Bean “Egg”
• Split Mung Bean (1 cup, soaked overnight) – Base for the vegan egg mixture; no direct substitute, but blended tofu can provide a similar texture.
• Soy Milk or Plant Milk (1 cup) – Adds moisture; any unsweetened plant milk can be used as a substitute.
• Tapioca Starch (1 1/4 tablespoons) – Provides creaminess and helps bind; cornstarch can be a substitute.
• Kala Namak (1 teaspoon) – Adds an eggy flavor; regular salt can work but will lack the distinctive taste.
• Nutritional Yeast (1 teaspoon) – Provides a cheesy flavor; this ingredient is optional for those who prefer less cheesiness.
• Garlic Powder (1/2 teaspoon) – Enhances flavor; fresh minced garlic can be used instead.
• Turmeric (1/2 teaspoon) – Provides color and a subtle flavor; can be omitted if desired, but it enhances appearance.

Step‑by‑Step Instructions for Potato Crust Mung Bean Quiche Vegan
Step 1: Preheat the Oven
Begin by preheating your oven to 355°F (180°C). This ensures that the heat is evenly distributed when you’re ready to bake your Potato Crust Mung Bean Quiche. While the oven heats up, you can prepare the potato crust, so everything flows smoothly.
Step 2: Boil Potatoes
Place your peeled and chopped potatoes into a large pot of salted water. Bring to a boil and cook for 25-30 minutes, or until fork-tender. Once they reach the desired texture, drain the potatoes and use a fork or potato masher to crush them into a thick paste, about ½ inch thick, and spread it evenly across the base of a greased 9-inch deep baking dish.
Step 3: Pre-Bake the Crust
Place your formed potato crust in the preheated oven and bake for 15 minutes. This step helps set the crust and gives it a slightly crispy texture, preparing it to hold the delicious filling of the Potato Crust Mung Bean Quiche.
Step 4: Blanching Spinach
In the meantime, bring a pot of water to a boil and blanch your fresh spinach for about 2 minutes. Immediately submerge the spinach in cold water to stop the cooking process, then squeeze out any excess moisture. This step keeps your quiche filling vibrant and prevents sogginess.
Step 5: Sauté Onions and Mushrooms
In a skillet, heat a tablespoon of avocado oil over medium heat. Add your sliced sweet onions and cook for about 8-10 minutes until they caramelize. Next, toss in the mushrooms and sauté for another 5-7 minutes, stirring occasionally, until they’ve lost their moisture. Season with soy sauce, coconut amino, and oregano for a flavor boost.
Step 6: Blend Mung Bean Mixture
In a blender, combine the soaked split mung beans, soy milk, tapioca starch, kala namak, nutritional yeast, garlic powder, and turmeric. Blend until smooth, achieving a creamy consistency. This mixture will serve as the egg substitute in your quiche, binding all the flavors together beautifully.
Step 7: Prepare Carrots
Using a vegetable peeler, create ribbon-like slices from your colorful carrots. These vibrant ribbons will be placed on top of the quiche. This adds not only visual appeal but also a delightful crunch to each slice of the Potato Crust Mung Bean Quiche.
Step 8: Assemble the Quiche
Once your potato crust is pre-baked, layer the blanched spinach over the crust. Then, evenly distribute the sautéed onion and mushroom mixture. Finally, pour the mung bean blend over the filling, ensuring it covers everything uniformly for optimal baking.
Step 9: Bake the Quiche
Return the assembled quiche to the oven and bake for 40-50 minutes. Look for a golden-brown top and a firm texture. A toothpick inserted into the middle should come out clean, indicating that the quiche has set properly.
Step 10: Cool and Serve
Once baked, let the quiche cool for about 10 minutes to make slicing easier. Carefully slice the Potato Crust Mung Bean Quiche Vegan and serve warm. Enjoy the incredible textures and flavors with your loved ones!

Make Ahead Options
These Potato Crust Mung Bean Quiches are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the potato crust and the filling components (sautéed vegetables and mung bean mixture) up to 24 hours in advance. Simply store the components in airtight containers in the refrigerator. For best results, assemble the quiche shortly before baking to ensure the potato crust remains crispy and the filling stays fresh. When you’re ready to enjoy, just layer the blanched spinach, sautéed mixture, and mung bean blend into the crust, and bake as directed. This way, you’ll have a delicious, homemade meal with minimal hassle!
Expert Tips for Potato Crust Mung Bean Quiche
- Choose the Right Potatoes: Select starchy potatoes like russets or Yukon golds for a fluffier crust. Avoid waxy potatoes, which could lead to a gummy texture.
- Don’t Rush the Sauté: Allow the onions to caramelize fully for maximum sweetness; this step adds depth to your filling. Stir occasionally and keep an eye on them to prevent burning.
- Cool Before Slicing: Let the quiche cool for 10 minutes after baking. This prevents it from falling apart when slicing and allows flavors to meld beautifully.
- Customize Your Fillings: Feel free to swap out veggies or add in legumes to enhance protein. Just ensure that all ingredients are well-drained to avoid a soggy quiche.
- Check for Doneness: A toothpick inserted should come out clean. If it’s still wet, give it a bit more time in the oven to achieve that firm and satisfying texture.
- Store Properly: Leftovers should be kept in an airtight container for up to 4 days. Reheat in the oven for the best taste—this keeps your Potato Crust Mung Bean Quiche Vegan crispy and delicious!
