VEGETABLE VEGAN FRITTATA

Vegan Frittata is a great way to use up leftover vegetables to make an easy inexpensive vegan meal that works for breakfast, lunch or even dinner!

The frittata is an Italian dish made with eggs and whatever vegetables you have on hand. In this vegan version we’ll be using an amazingly flavorful tofu base ‘egg’ mixture and tons of vegetables for an absolutely delicious vegan frittata!

I’ve been making this frittata for many years and it’s a family favorite. Whether it’s breakfast, lunch or dinner, everyone loves this flavorful main dish!

For those who are used to the egg version, it may not be the exact same, but for what it is it’s just perfect in my book. And what it is, is low cholesterol, fiber filled and a good amount of protein for a healthy vegan main dish.

Personally, I find this tofu frittata to be both flavorful and filling. It doesn’t need much, but I do love to finish it off with avocado and a drizzle of sriracha for some extra-spicy heat!

Vegan frittata can be served anytime of day. Plus, it’s great for using up produce that’s about to expire and will handle a large assortment of veggies.

Ingredients You’ll Need

In this recipe, tofu and spices are pureed for an ‘egg’ mixture and mixed with sauteed vegetables, then baked in the oven until golden on the outside and tender on the inside creating the ultimate vegetable vegan frittata.

Here is everything you’ll need, plus ideas for substituting ingredients:

  • Potatoes – use any color, white, red, gold or russet (with or without the skin).
  • Onion – any color will do.
  • Bell pepper – use your favorite color bell peppers.
  • Zucchini
  • Yellow squash – sub with a handful of cherry tomatoes cut in half.
  • Garlic
  • Organic silken tofu – Soft or firm (silken pref.). Some tofus when pureed have a chalky taste, you’ll have to find one that works for you. Typically silken tofu will not have a chalky taste. No need to press the tofu.
  • Unsweetened non-dairy milk – use your favorite type of plant milk.
  • Cornstarch (pref. organic) – sub with arrowroot or tapioca flour
  • Nutritional yeast
  • Mustard – use dijon or whole grain (sub with mustard powder)
  • Tarragon – sub with thyme or basil (or any combo)
  • Garlic powder
  • Turmeric
  • Red pepper flakes
  • Salt and pepper

Can I Add Other Vegetables?

Yes! What I love about this frittata is how easy it is to customize. It’s perfect when you need to clean out the fridge and can handle just about any veggie! Sub in halved cherry tomatoes, broccoli, mushrooms, spinach, kale, green onions, and more.

How To Make Vegan Frittata

  • Preheat oven to 375 degrees F.
  • Start by making the tofu egg mixture by adding the tofu, nutritional yeast, dijon, cornstarch, garlic powder, herbs, red pepper flakes, salt and pepper to the bowl of a food processor or blender, and process until smooth, stopping to scrape down the sides as needed.

  • Once ready, add sauce mixture to cooked vegetables.

  • Lastly, add the vegan vegetable frittata mixture to a 9 inch springform pan (or any 9 x 11 shallow dish will do).
  • Place in the oven and bake for about 40 – 45 minutes. The frittata you see here was baked the full 45 minutes.

And voila, a delicious, vegan frittata to serve to family and friends!

Serving Suggestions

How To Store Leftovers

  • Refrigerator: Leftovers will keep for 4 – 5 days in the refrigerator, stored in a covered container.
  • Freezer: This vegan frittata freezes well for up to 2 – 3 months! To freeze, let cool completely and store in freezer safe containers.
  • Reheat: To reheat, simply warm in a preheated oven set at 350 degrees F. for 10 – 15 minutes, until warmed through. You may want to cover it so it doesn’t brown. You can also zap single servings in the microwave for 30 – 60 seconds, or until warm.

Can I Make Vegan Frittata Ahead?

Yes, and it will taste even better as the flavors will have time to meld together! To make this vegan frittata recipe ahead, simply prepare the frittata up until baking and store in the refrigerator until ready to bake. When ready, bake as directed the full 45 minutes, covering towards the end as needed to keep it from browning too much.

  • 2 medium potatoes, diced (with or without the skin)
  • 1 small onion, diced
  • 1 bell pepper, diced
  • 1 zucchini, diced

for the blender/food processor

  • 1 package (16 oz) organic silken tofu (soft or firm), drained (no pressing needed)
  • 1/4 cup unsweetened non-dairy milk
  • 2 heaping teaspoons cornstarch, arrowroot or tapioca flour
  • 23 tablespoons nutritional yeast
  • 1 teaspoon mustard (any kind) or 1/2 teaspoon mustard powder
  • 1 1/2 teaspoons dried tarragon, thyme or basil (or a combo)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon turmeric
  • 1/8 teaspoon pepper (black or white)

Instructions

Preheat oven to 375 degrees F.

Saute: Heat oil in a pan over medium heat, saute potatoes for 5 minutes, add onion and cook an additional 5 minutes. Add bell pepper, zucchini and garlic, cook until softened. Add tomatoes and optional red pepper flakes, cook another minute or two. Season with salt and pepper to taste.

Tofu egg: In a food processor/blender, combine the remaining ingredients and process until smooth. Taste for seasoning.

Assemble: Add the tofu mixture to the pan the vegetables cooked in and mix well. Spoon mixture into a lightly greased 9 inch round pie/quiche dish or springform pan. Level the top flat with the back of a spatula or spoon and make sure all edges are filled.

Bake: Place on the middle rack and bake for 35 – 45 minutes, frittata should be firm to the touch. If top starts to brown too much, cover with foil or small silpat. Remove and let cool for at least 10 minutes. If using a pie/quiche dish, loosen the edges of the frittata, place a plate over top and carefully flip so frittata falls onto the plate and serve (this step is optional).

This frittata is wonderful with sliced avocado and a little sriracha for heat.

Serves 4 – 6

Store: Leftovers can be stored in the refrigerator for 4 – 5 days. To keep longer, store in the freezer using freezer safe containers for up to 2 – 3 months.

Notes

I suggest using at least a 9 inch round dish or larger.

  1. Works great every time we make it. Everyone loves it. Thank you so much for sharing this recipe!!

  2. Elizabeth T says:

    How much egg do I use if I only want vegetarian?

    1. Julie | The Simple Veganista says:

      This is a vegan frittata, so I can’t recommend how many eggs you would need since I have never tried it. I suggest searching for another recipe if you want to use eggs. Sorry I couldn’t help, Elizabeth!

  3. Instead of Cornstarch, can you use guar gum? That’s my preferred thickener.

    1. Julie | The Simple Veganista says:

      Yes, you can use your preferred thickener. Enjoy!

  4. Is it better to use firm or silken tofu?

    1. Julie | The Simple Veganista says:

      I think either will be fine. I’d be more concerned with the flavor and find a tofu brand that doesn’t taste chalky. I hope that helps. Enjoy!
