Vegan Mushroom Filo Pie (Flaky, Spanakopita-Style)
This rustic mushroom pie wraps a savory filling of mushrooms, caramelized onion, garlic, and fresh dill in layers of golden, flaky filo pastry. It bakes up crisp on top and tender inside, it is fully vegan, and it comes together with simple pantry staples.
A good mushroom pie is proof that you do not need meat to make something that feels properly hearty and special. Layers of crisp phyllo around a savoury, garlicky mushroom filling – it is comfort food that also happens to look like you tried. I make it for gatherings where I want one show-stopping vegan main nobody feels like they are settling for. Cook the filling until it is quite dry; a wet filling steams the pastry from the inside and you lose all that crispness.
Why this pie is worth the filo
- Deeply savory. Caramelized onions, garlic, and mushrooms build big, layered flavor.
- Flaky and golden. Layered filo gives a shattering, crisp crust.
- Fully vegan. No eggs, no dairy, no fuss.
- Great hot or cold. Perfect for lunchboxes and picnics.
About the mushrooms and filo
Mushrooms are the star. White or cremini work well, and a mix of wild mushrooms adds an even deeper, earthier flavor. Chop them finely so the filling holds together.
Filo (phyllo) pastry gives the pie its signature flaky layers. Most store-bought filo is naturally vegan; just brush each layer with oil instead of butter.
Onion, garlic, and herbs are the backbone of the flavor. Caramelizing the onion and adding a splash of white wine give the filling real depth, while fresh dill keeps it bright. Parsley or thyme work in place of dill too.
How the pie comes together
- Build the filling. Caramelize the onion, add garlic and thyme, then the mushrooms, and cook until golden and dry. Deglaze with a splash of white wine.
- Season well. Stir in dill, salt, and pepper, then let the filling cool so it does not soak the pastry.
- Layer the filo. Brush sheets with oil, layer them, add the filling, and fold or top with more sheets.
- Bake until golden. Brush the top, score into portions, and bake until deeply crisp.
Tips and ways to change it up
- Dry the mushrooms out. Cook off all the liquid so the filo stays crisp, not soggy.
- Make it creamy. Stir a spoon of vegan cream cheese or cashew cream into the cooled filling.
- Add greens. A handful of wilted spinach turns it into a mushroom-spinach pie.
- Use puff pastry. Swap filo for vegan puff pastry for an even richer crust.
Shape it as a spiral (and other easy wins)
For a version that looks like it came from a bakery, coil it: spread the mushroom filling along buttered filo sheets, roll each into a long log, then curl the logs into a loose spiral in a round tin. It bakes into a golden, snail-shell pie that slices into pretty wedges. A handful of chopped toasted walnuts folded into the filling adds crunch and a nutty depth that suits mushrooms, and a spoon of vegan cream cheese makes it richer without any dairy.

Making it ahead and storing
- Fridge: store for up to 3 days in an airtight container.
- Freezer: freeze baked slices for up to 2 months.
- Reheat: warm in the oven to bring back the crisp crust.
This rustic version is lighter and flakier than our richer creamy mushroom pie, which has a creamy, saucy filling. For more ideas, try our vegan mushroom tart or the filo-wrapped vegan spanakopita.

Rustic Mushroom Pie
Equipment
- Large skillet
- Baking dish or tray
- Pastry brush
- Wooden spoon
Ingredients
- 1.5 lb mushrooms finely chopped
- 2 onions finely chopped
- 3 cloves garlic minced
- 4 tbsp olive oil plus more for brushing
- 2 tsp fresh thyme leaves, or 1 tsp dried
- ¼ cup white wine or 1 tbsp tamari
- ⅓ cup dill fresh, chopped
- 1 lb filo pastry thawed
- 3 tbsp plant milk for brushing
- Salt and black pepper to taste
- ⅓ cup walnuts toasted and chopped, optional
Instructions
- Heat 4 tbsp olive oil in a large skillet and cook the onions gently for 12 to 15 minutes, stirring often, until soft, golden, and caramelized — this is where a lot of the flavor comes from.
- Add the garlic and thyme and cook for another minute, until fragrant. Turn up the heat, add the mushrooms, and cook for 12 to 15 minutes, until all the liquid has evaporated and they are golden.
- Pour in the white wine and let it bubble for a minute or two, scraping up the tasty bits from the pan. Stir in the dill, season well with salt and pepper, and let the filling cool.
- Preheat the oven to 375°F (190°C) and brush a baking dish with oil. Layer about half the filo sheets in the dish, brushing each with oil.
- Spread the cooled mushroom filling evenly, then top with the remaining filo sheets, brushing each with oil.
- Tuck in the edges, brush the top with plant milk, and score into portions with a sharp knife.
- Bake for 35 to 40 minutes, until deeply golden and crisp. Cool slightly before slicing.
- To shape it as a spiral, roll the filled filo sheets into long logs and coil them into a round tin; fold chopped toasted walnuts into the filling first for extra crunch.
