Ingredients
2 tablespoons extra virgin olive oil or avocado oil
½ medium yellow onion, thinly sliced
½ pound asparagus, woody ends discarded, sliced into 1½-inch pieces
1 ¾ teaspoons fine sea salt, divided
2 cups (about 4 ounces) fresh baby spinach
2 (14-ounce) packages firm tofu, drained
⅓ cup nutritional yeast
2 tablespoons apple cider vinegar
2 teaspoons onion powder
2 teaspoons garlic powder or granulated garlic
½ teaspoon turmeric powder
Preparation
- Step 1
Heat the oven to 375 degrees.
- Step 2
Warm a cast-iron or other oven-safe skillet (see Tip) over medium-high heat. Add the olive oil, then the sliced onion. Stir and reduce the heat to medium. Cook, stirring frequently, until the onions are soft, about 4 minutes.
- Step 3
Stir in the asparagus and a pinch of salt, about ¼ teaspoon. Cover and cook for 4 minutes, until the asparagus is bright green and crisp.
- Step 4
Remove the skillet from the heat and add the spinach. Stir it until it wilts.
- Step 5
Use your hands to gently press out any excess water from the tofu, then crumble it into the bowl of a food processor. Add the nutritional yeast, apple cider vinegar, onion powder, garlic powder, turmeric powder and the remaining 1½ teaspoons salt. Blend until the ingredients are combined and the tofu is smooth.
- Step 6
Transfer the blended tofu to the skillet and stir to combine it with the vegetables. Smooth the top of the tofu with a spoon or a spatula.
- Step 7
Bake for 50 minutes, until the surface of the frittata is golden. Cool for 10 minutes before serving hot.
The thickness of your frittata will depend on the pan size. A 10-inch skillet is ideal but any oven-safe pan will work.

If you want an eggier flavor, try Indian black salt (kala namak) instead of the sea salt - I've used it in this kind of recipe before.
Good with half the sodium and some fresh herbs.
Healthy and easy to make. Appeals to vegetarians and omnivores as well.
I wonder if I overcooked this. The texture was good, and I liked the taste of the raw tofu mixture, but the flavor of the finished product was a little cardboardy.
I will say that I had pretty low expectations for this one and boy was I wrong - it was easy and delicious. My food processor is heavy and tucked away, so I used an immersion blender out of laziness. My tofu mixture wasn't as smooth as in the picture, but it still worked really well. I second the comment about really not pressing out much liquid - you need it. With that in mind I would recommend using tofu packed in liquid and not a super firm "brick."
Can this be made with eggs instead of tofu as a crustless quiche?
tina, respectfully, this is a vegan recipe. there are tons of egg-filled quiches on this website.
