Vegan Wild Mushroom Puff Pastry Roast

There is something undeniably magical about pulling a beautifully golden puff pastry from the oven. As the flaky layers rise and crisp, the kitchen fills with the rich aroma of roasted mushrooms, fresh herbs, and buttery pastry. It feels special without being complicated—a recipe that transforms a handful of wholesome ingredients into an impressive meal worthy of a holiday table or a cozy weekend dinner.

This Vegan Wild Mushroom Puff Pastry celebrates three exceptional mushrooms, each bringing its own unique texture and flavor. Earthy maitake mushrooms become wonderfully crisp around the edges while remaining tender inside. Brown beech mushrooms contribute a pleasantly nutty bite, and delicate white bunapi mushrooms add subtle sweetness that balances the savory filling. Combined with fragrant thyme, rosemary, garlic, shallots, and a touch of white miso for umami depth, the filling is rich, comforting, and full of flavor.

Wrapped inside crisp vegan puff pastry, every slice reveals beautiful layers of golden crust surrounding a hearty mushroom filling. It's elegant enough to serve as the centerpiece for Thanksgiving, Christmas, or an intimate dinner party, yet simple enough to make for a Sunday supper with family.

One of my favorite things about this recipe is its versatility. Pair it with creamy mashed potatoes, roasted vegetables, a crisp green salad, or simply enjoy it with a glass of your favorite wine. Leftovers are equally delicious, reheated until the pastry becomes crisp once again.

Whether you're entertaining vegan guests or simply looking for a stunning plant-based entrée, this mushroom puff pastry proves that seasonal vegetables and simple ingredients can create something truly memorable. It’s the kind of recipe that feels both rustic and refined—a comforting dish you'll find yourself making throughout the cooler months.

Serves: 4–6
Prep Time: 20 minutes
Cook Time: 35 minutes

Ingredients

For the Mushroom Filling

• 8 ounces maitake mushrooms, torn into bite-sized pieces

• 4 ounces brown beech mushrooms, trimmed

• 4 ounces bunapi (white beech) mushrooms, trimmed

• 2 tablespoons extra-virgin olive oil

• 2 tablespoons vegan butter

• 1 small shallot, finely diced

• 3 cloves garlic, minced

• 2 teaspoons fresh thyme leaves

• 1 teaspoon chopped fresh rosemary

• ½ teaspoon sea salt

• ¼ teaspoon freshly cracked black pepper

• ¼ teaspoon crushed red pepper flakes (optional)

• 2 tablespoons dry white wine (optional)

• 2 teaspoons tamari or soy sauce

• 1 teaspoon white miso paste

• 1 teaspoon Dijon mustard

• 2 tablespoons chopped fresh parsley

• 2 teaspoons cornstarch

• 2 tablespoons unsweetened oat milk

For the Puff Pastry

• 1 sheet vegan puff pastry, thawed (I use Dufour vegan puff pastry)

• 1 tablespoon unsweetened plant milk

• 1 teaspoon maple syrup

• Flaky sea salt

• Fresh thyme leaves for garnish

Instructions

1. Prepare the Filling

Heat the olive oil and vegan butter in a large skillet over medium-high heat.

Add the maitake, brown beech, and bunapi mushrooms. Let them cook undisturbed for 3–4 minutes before stirring so they develop deep golden edges. Continue cooking until most of the moisture has evaporated, about 8–10 minutes.

Stir in the shallot and cook for 2 minutes. Add the garlic, thyme, rosemary, salt, pepper, and red pepper flakes, cooking for another minute until fragrant.

Deglaze the pan with the white wine (if using) and allow it to reduce completely.

Whisk together the tamari, miso, Dijon, oat milk, and cornstarch. Pour into the pan and stir until the filling lightly thickens, about 2 minutes.

Remove from the heat and fold in the parsley. Allow the filling to cool for 10–15 minutes.

2. Assemble the Pastry

Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.

Lightly roll the puff pastry into a rectangle approximately 10 x 13 inches. Lightly puncture the puff pastry with a fork.

Spoon the cooled mushroom filling down the center third of the pastry, leaving a 1-inch border at both ends. Roll the puff pastry and press the edges to seal. Using a sharp knife, cut 3-5 diagonal lines across the top.

Mix the plant milk with the maple syrup and brush over the pastry. Sprinkle lightly with flaky sea salt and a few fresh thyme leaves.

3. Bake

Bake for 35–40 minutes, or until the pastry is deeply golden, crisp, and puffed.

Allow to rest for 10 minutes before slicing.
