Caramelized Onion Vegan Quiche

This easy sweet and savory Caramelized Onion Vegan Quiche is made with tofu and has a chickpea flour crust. Perfect for parties!

Caramelized onions are one of my favorite ingredients. They take any dish to the next level.

Many times I pair them with mushrooms, but for this Caramelized Onion Vegan Quiche they are the star of the show.

For this vegan quiche recipe I mixed the caramelized onions with tofu. Then I added tamari and white miso paste for a savory umami flavor.

I added nutritional yeast for a cheesy flavor. You could add the caramelized onions to the quiche filling last, and pulse until you get your desired consistency.

I saved about a quarter cup of the onions to spread on top.

Whether you add the onions first or last, it'll taste great. It just depends on the textures you prefer. I will probably make it with thicker chunks next time to see if I like it better.

How to Make This Recipe

1. Pie Crust: Mix chickpea flour, ice cold water, olive oil, and salt. It should be the consistency of play dough.
2. Oil a 9" pan with olive oil. Oil your hands as well so they don't stick to the dough.
3. Spread the dough out in the pan, including the edges. Bake at 350° for 20-25 minutes, or until starting to turn golden.
4. Filling: Heat the olive oil in a pan on medium low heat. Add sliced onions. Sprinkle salt on top.
5. Stir the onions every few minutes or so. Cook about 35-40 minutes until they are well-browned. Add a small amount of water if they start to stick. Add balsamic vinegar and cook until it's evaporated.
6. In a food processor, mix caramelized onions - saving ¼ cup to place on top, tofu, tamari, miso paste, nutritional yeast, and salt and pepper.
7. Spread filling on chickpea flour crust. Sprinkle reserved onions on top. Bake at 400° for 20-25 minutes, or until browned.

Tips

• For caramelized onions you need some patience. It takes a good 40 minutes to get nicely browned onions. Slow and steady wins the race.
• If the onions start to stick, add a little water, like a quarter of a cup or so.
• Balsamic vinegar adds a wonderful flavor to caramelized onions. I always add a couple of splashes near the end of the cooking time.
• If you want a chunky onion filling, add the caramelized onions last to the tofu mixture and pulse until you get the desired consistency.
• Save about a quarter cup of caramelized onions to top the quiche.
• Pre-bake the chickpea flour crust, then add the filling and bake some more. That way you'll have a crunchy flaky crust.
• Don't have a cover for your quiche pan? No problem! Just use that shower cap you got from your last vacation. It works great in place of plastic wrap.

Do I Need To Press the Tofu?

For this recipe it isn't necessary to press the tofu. Drain it if it's the refrigerated kind.

Substitutions

• You can use any vegetables you like, just cook them first and keep in mind ratios and water content. I made a Spinach and Broccoli Vegan Quiche awhile back that's very similar to this recipe.
• The only flour I've used for the crust is chickpea flour because I really like it, but you could probably use a gluten free flour mix as well.

Recipe

This sweet and savory vegan quiche has a creamy filling with a flaky crust. It will be the hit of your next brunch.
