This vegan frittata is the savoury breakfast of my dreams! When I used to eat eggs, I loved quiche and frittatas. I knew I wanted the same taste and texture when I went vegan and yes, I have found it! First, it was my quiche muffins. Then my vegan quiche. Now? This vegan frittata recipe.

This is essentially a crustless quiche and it’s OH SO GOOD! It’s also so easy to make, friends. Just pour into your sheet pan, bake, slice and enjoy! It has the perfect taste, texture, and it’s so customisable.

Notes on ingredients

Scroll down to the recipe card to find the ingredient quantities and recipe instructions.

  • Tofu – Always use medium, firm, or extra-firm tofu. Don’t use silken tofu.
  • Nutritional yeast – Get the best quality you can find! Also ensure it’s the fortified one with B12 for extra nutrients.   
  • Fillings – I used mushrooms, spinach and tomatoes for my filling ingredients in this vegan frittata. Feel free to switch it up! You can add vegan cheese, meat replacements, and anything else you love! Just nothing too heavy that might sink.
  • Turmeric – Don’t add too much or you’ll get a weird neon yellow colour! It’ll look light at first, but it gets more prominent as it bakes.
  • Baking powder
  • Black salt (kala namak) – This isn’t necessary, but it really brings out that authentic egg-y taste! If you have it use it, but it isn’t a deal breaker. A little goes a LONG way. 

How to Make a Vegan Frittata

Tofu in a press.
  • Prepare. Grease a sheet pan with some vegan butter and set it aside. Press your tofu for at least 20 minutes and set it aside until you are ready for it. (I usually press the tofu while I’m prepping the veggies.)
Onions cooking in a pan.
  • Caramelise the onions. In a pan over medium-high heat, heat 1 tablespoon of the coconut oil. Stir in the onions. Lower the heat to medium and cook the onions for 15 to 30 minutes, or until caramelised.

  • Add the tomatoes and mushrooms. Add the extra oil, along with the tomatoes, garlic, and mushrooms. Bring the heat back up to medium-high and sauté for 15 minutes, stirring occasionally,  until tomatoes are slightly broken down. Season with salt and pepper to taste.

  • Wilt the spinach. Add the spinach and sauté for another two minutes until it is wilted. Remove from heat and set aside.
Dry and wet ingredients in a blender.
  • Make the tofu “egg” mixture. In a high powered blender, add the tofu, vegan milk, nutritional yeast, sea salt and black pepper, turmeric, baking powder and vegan Parmesan. (You can do this while the onions sauté to save time.) If you have any kala namak, add it now. Blend on high until everything is completely smooth and there are no lumps, about 2 to 3 minutes.

  • Assemble. Add the tomato filling to your greased pan. Pour the tofu mixture over the tomato filling, and lightly stir them both together to combine.

  • Bake. Tent with foil, and bake for 20 minutes. Remove the foil and bake for an additional 20 minutes, or until the top is golden brown and the frittata is cooked through.
  • Serve. Allow to cool for about 10 minutes, then cut and serve. Enjoy! 

Tips for Success

  • Grease the pan well. You don’t want your vegan frittata to be impossible to remove! Even with a nonstick sheet pan, I like to grease it with butter.
  • Always press your tofu. Don’t skip pressing! This presses out the liquid from the tofu so it’s ready to absorb the flavour we’re adding to it. Learn more in my tofu 101 post.  
  • Blend until incredibly smooth. If you don’t have a high powered blender, blend it twice! You want it to be completely smooth, with no lumps at all.
  • Switch up the veggies. This vegan frittata recipe can be adapted to whatever is in season. Brussels sprouts, butternut squash, zucchini, and kale would all be excellent.

5 (from 22 ratings)

Ingredients

  • 2 pounds firm tofu, pressed (two blocks of tofu)
  • 3 tablespoons oil
  • 1 large white or red onion, sliced chopped in half
  • 2 cups halved cherry tomatoes, (1 dry pint)
  • 8 cloves garlic, minced
  • 3 cups baby mushrooms, chopped (350g)
  • sea salt and pepper to taste for the veggies
  • 4 cups  fresh spinach, chopped
  • 2 cups vegan milk, any vegan milk works
  • 6 tablespoons nutritional yeast
  • 1 ½ teaspoon sea salt
  • ½ teaspoon ground black pepper
  • ½ teaspoon turmeric, for colour
  • 1 teaspoon baking powder
  • 1 tablespoon vegan parmesan, (optional)
  • Two pinches black salt kala namak, totally optional**
  • 4 teaspoons dried chives or 3 tablespoons freshly chopped chives

Instructions 

  • Preheat oven to 375°F/190°C. Begin to press your tofu and set aside until you are ready for it.
  • Grease your sheet pan with some vegan butter (on the wrapper or parchment paper) and set it aside. Press your tofu for at least 20 minutes and set aside until you are ready for it. I start this, then start on the rest of the recipe. By the time you're ready for it the time would've elapsed.
  • In a large pan over medium-high heat, heat 2 tablespoons of the oil. Add in the onions and stir to combine. Lower heat to medium-low and stir the onions for 15 minutes (you could even go up to 30 minutes depending on the time you have if you want to further caramelise them, stirring often). Season lightly with sea salt.
  • After the onions are cooked down, add in the last tablespoon of oil and the tomatoes, garlic and mushrooms, stirring to coat in the oil. Bring heat back up to medium-high and sauté for 15 minutes, stirring occasionally, until tomatoes are slightly broken down. Season with salt and pepper to taste.
  • Add in the spinach and sauté for another two minutes until it is wilted. Remove from heat and set aside.
  • In a high powered blender, add the tofu, vegan milk, nutritional yeast, sea salt and black pepper, turmeric, and baking powder and vegan parmesan (optional). (You can do this while the onions sauté to save time.) If you have any kala namak, add it now. Blend on high until everything is completely smooth and there are no lumps, about 1 to 2 minutes. I pause, scrape down, and blend mine twice to ensure this.
  • Add the tomato filling to your greased 9×13 pan. Pour the tofu mixture over the tomato filling, and lightly stir them both together to combine. Sprinkle the chives on top.
  • Tent it with foil, and bake for 20 minutes. Gently remove the foil (there will be a lot of steam underneath it!), place back in the oven and bake for an additional 20 minutes until the top is golden brown and the frittata is cooked through.
  • Allow to cool for about 10 minutes, then cut into and serve. Serve with extra chives on top. Enjoy!
