Step 1

In a large bowl, whisk together the flour and salt. Add the cold cubed vegan butter and the cold water. Knead with your hands until a smooth dough forms (or use a food processor to process the ingredients into a dough).

Step 2

Form the dough into a disc, wrap tightly in plastic foil and refrigerate for 30 minutes.

Step 3

Preheat oven to 400°F (200°C).

Step 4

After the chill time roll out the dough evenly on a lightly floured surface a little larger than your pan. Then transfer into a lightly greased 10-inch (25,5cm) tart pan (or 9-inch pie dish), pressing the bottom and sides firmly. Prick the bottom a few times with a fork, then line with parchment and fill with pie weights (e.g. dried beans, chickpeas or rice). Pre-bake the crust for 10 minutes. (*see step-by-step photos in this blog post).

Step 5

In the meantime, make the filling. Clean and cut the leek (*see step-by-step photos here). Thinly slice the mushrooms (or chop them if they’re too large). Mince the garlic and roughly chop the chestnuts.

Step 6

Heat the oil in a large skillet or pan. Add the leeks and mushrooms and sauté for about 5 minutes. Then add the garlic and cook for another 2-3 minutes, or until the leeks are soft and the mushrooms are tender. Generously season with salt, pepper and nutritional yeast flakes.

Step 7

Blend the silken firm tofu and cornstarch until creamy, then mix in the chestnuts (if using). Add the tofu mixture to the pan with the mushrooms and leeks. Stir to combine. Taste and adjust seasonings as needed.

Step 8

Spread the tofu quiche filling onto the pre-baked crust, smoothing out evenly. (Brush the edges with non-dairy cream for a golden color shiny as desired).

Step 9

Bake the vegan quiche at 355°F (180°C) for about 30-40 minutes, or until the filling is set and slightly golden-browned. (*If the top gets too dark during baking, cover loosely with aluminum foil or parchment paper.)

Step 10

Allow to cool for about 10 minutes. Then garnish with more sautéed garlic mushrooms, toasted pine nuts, vegan parmesan cheese, and fresh herbs. Enjoy!
