Eggless Quiche

This vegan quiche slices like a regular quiche, it is creamy and it is great hot, cold or at room temperature.

It is everything you might expect from a quiche but it doesn’t contain any eggs.

“Is this some sort of miracle?” I hear you ask. I too was astonished when I realised that eggs were not, after all, a prerequisite for a tasty quiche!

Firm silken tofu provides the creamy texture and sets beautifully when cooked and cooled. It is the perfect foil for all the flavours and textures in my mushroom and leek quiche.

Friends and family have told me that, if I hadn’t announced in my usual overdramatic fashion that this was a vegan quiche, they wouldn’t have guessed that it was egg-free!

It is easily adaptable to include seasonal veg – watch this space for more flavour combinations as the year goes on!

Pastry for Vegan Quiche

Shop Bought Vegan Pastry

If you want to make this recipe even easier use shop-bought ready to roll shortcrust pastry. You’ll find it in the chiller section of most supermarkets.

JusRol shortcrust is suitable for vegans as are most of the own-brand options but do check the ingredients list just to be sure. 

Homemade Vegan Shortcrust Pastry

If you follow my recipe for homemade pastry do make sure that all your ingredients are well chilled and handle it as little as possible to ensure a crispy crust.

Chill it for about 20 minutes before rolling out to fit your dish.

Lift it gently into your dish and persuade it into place using a small ball of pastry to press it into the edges of your dish. Leave it to chill for a further 30 minutes. 

Chilling pastry at every stage allows it to rest and recover from your ministrations and prevents it from shrinking when baked.

Spoon your filling straight into the prepared case. I don’t blind bake my pastry for quiche now that I’m vegan – another bonus!

Because the filling is not liquid, like a conventional egg-based quiche, it can be spooned in and baked without the risk of a soggy bottom!

Vegan Quiche With Mushrooms and Leek

Ingredients and full instructions are in the recipe card at the end of this post.

The filling for this quiche is really easy to put together!

  • Gently fry leeks, red onion and mushrooms until cooked and all liquid has evaporated off. 
  • Add garlic and herbs and fry for a minute until aromatic and allow to cool.
  • Whisk together the firm silken tofu, Dijon mustard and nutritional yeast and stir into the cooled vegetables.
  • Season to taste with salt and black pepper before spooning into your prepared pastry shell and baking. 

Serving Suggestions

I served my quiche for lunch, at room temperature, with some delicious no mayo potato salad, baby plum tomatoes and peppery rocket leaves.

Can You Freeze Quiche?

Vegan quiche keeps very well, covered, in the fridge for up to three days.

It is not suitable for freezing because the texture of tofu changes when it is frozen and no one wants to eat a chewy quiche!

If you want to get ahead you can freeze the prepared, raw, pastry shell and bake it from frozen, adding 5 minutes to the baking time.
