Ingredients to make Vegan Mushroom Tart
Here's what you need to make this delicious mushroom tart:
- Mushrooms: Of course, the star of the show! I've used White Button Mushrooms, but you can use any mushrooms you like or have available, whether it's portobello, chestnut, cremini or wild mushrooms.
- Puff Pastry: The main ingredient of our tart. Check the ingredients if you want to make it vegan, but most are dairy- and egg-free.
- Onion and garlic: This is the base for almost all my recipes.
- Dairy-free cheese: I used dairy-free Violife cheese, but it would be delicious with other vegan cheese as well.
- Vegan butter: To sauté the onion and mushrooms.
- Soya sauce: For the umami flavour. It makes the mushrooms super tasty. If you don't believe me, try it!
- Thyme: Mushrooms and thyme are best friends. But you can use rosemary or Italian mixed herbs too.
- Dairy-free milk and turmeric ( optional ): A mixture of dairy-free milk and turmeric will give an extra golden shine to the puff pastry.

how to make vegan mushroom tart
You will find the full recipe with all the measurements in the recipe card at the bottom of the post.
If you're using frozen puff pastry, you must ensure it's thawed. Leave the pastry in the fridge overnight.



- Firstly, slice the onion and chop the mushroom roughly.
- Heat butter in a large skillet over medium-high heat and sauté the onion with a pinch of salt until translucent, then add garlic and stir it together.
- Once the onion and garlic are translucent, add the chopped mushrooms and the thyme.
- Cook until the mushrooms are soft and nicely brown and release all their juices. Ensure you cook out all the water; otherwise, your puff pastry will be soggy.
- Stir in soya sauce. Let them cool slightly.
- Meanwhile, preheat the oven to 190c and roll out the puff pastry from the fridge.
- Place your pastry on a baking tray with parchment paper. Score the edges around the pastry, making sure not to cut all the way through.
- Then prick the pastry sheet so it won't bubble up during baking.
- Sprinkle the grated cheese and top with sauteed mushrooms.
- Brush the edges with a mixture of non-dairy milk and turmeric to make it golden brown.
- Bake it for 25-30 minutes until it's nicely puffed and golden brown.
Sprinkle with fresh parsley and ENJOY!

Storage
This vegan mushroom tart is best served right away. But if you have any, in the fridge, you can store it in an airtight container for up to 3 days.
Top tip
- When cooking the mushrooms, ensure you leave the salt off until the last minute; otherwise, your mushrooms will be rubbery. Adding salt would draw out all the moisture from the mushrooms, and you'd be steaming them.
- Before topping the pastry sheet, cook all the water under the mushroom.
- When scoring the edges of the pastry, make sure you do not cut them through all the way around.
- Allow the mushrooms to cool down slightly before adding them to the top of the pastry.
- The non-dairy milk and turmeric mixture will make the pastry golden brown during baking.
- Make sure to prick the pastry before sprinkling the shredded cheese so it won't bubble up when baking.

Hello,
In two different places you mention sauteing onions with a pinch of ???. What is it? Salt?
Thanks. This looks great.
