I discovered this recipe years ago when looking for something special to serve my vegan friends during the holidays, and it’s become a tradition ever since.
Why This Recipe is Awesome
This Vegan Mushroom Wellington truly shines as a plant-based alternative that doesn’t feel like a compromise. The umami-rich mushrooms create a meaty texture that satisfies on a primal level, while herbs and garlic infuse the filling with complex flavors that develop beautifully during baking. What makes this recipe particularly special is how it transforms humble ingredients into something spectacular.
The flaky, golden pastry creates that “wow” moment when you bring it to the table, sliced to reveal the colorful layers inside. Unlike many vegan centerpieces that require obscure ingredients, this wellington uses accessible components you can find at most supermarkets.

It’s fancy enough for Christmas dinner but achievable enough for a Sunday supper when you want something special.
Equipment needed: Baking sheet, parchment paper, large skillet, food processor, sharp knife, pastry brush
Vegan Mushroom Wellington
Ingredients
- 2 sheets vegan puff pastry most store-bought varieties are accidentally vegan
- 2 pounds mixed mushrooms portobello, cremini, shiitake, roughly chopped
- 1 large yellow onion finely diced
- 4 cloves garlic minced
- 3 tablespoons olive oil divided
- 2 tablespoons soy sauce or tamari
- 1 tablespoon balsamic vinegar
- 1 cup walnuts toasted and chopped
- ½ cup breadcrumbs ensure they’re vegan
- 3 tablespoons fresh thyme leaves
- 2 tablespoons fresh rosemary minced
- Salt and freshly ground black pepper to taste
- ½ cup cooked and cooled wild rice optional, for extra texture
- 3 tablespoons plant-based milk for brushing
- 1 tablespoon maple syrup for brushing, creates a golden finish
Instructions
- Prepare your workspace by preheating your oven to 375°F (190°C) and lining a baking sheet with parchment paper. Take the puff pastry out of the freezer to thaw according to package instructions.
- Cook the mushrooms properly by working in batches. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add about one-third of the mushrooms and cook until they release their moisture and begin to brown, about 5-7 minutes. Transfer to a large bowl and repeat with remaining mushrooms, adding more oil as needed.
- Sauté the aromatics in the same pan using the remaining oil. Cook the onion until translucent, about 5 minutes, then add garlic and cook for another minute until fragrant. Add to the mushroom bowl.
- Create the flavor base by returning the mushroom mixture to the pan. Add soy sauce and balsamic vinegar, stirring to coat everything evenly. Cook for another 2-3 minutes until the liquid is mostly absorbed.
- Process half the mixture in a food processor until finely chopped but not puréed. This creates a binding texture while leaving some mushroom pieces intact for a meaty bite.
- Combine all filling components in a large bowl—processed mushrooms, chopped mushrooms, walnuts, breadcrumbs, herbs, and wild rice if using. Season with salt and pepper. Let cool completely (warm filling will make the pastry soggy).
- Assemble your wellington by rolling out one puff pastry sheet on a floured surface to about 11 x 15 inches. Transfer to the prepared baking sheet. Place the cooled filling mixture in the center, forming a compact loaf shape with about 1.5 inches of pastry exposed on all sides.
- Create the top crust by rolling out the second pastry sheet to the same size and draping it over the filling. Press the edges of both pastry sheets together firmly, trimming any excess. Crimp the edges with a fork to seal.
- Make it golden by mixing plant milk with maple syrup and brushing this mixture over the entire pastry. Cut 3-4 small slits in the top to allow steam to escape during baking.
- Bake until perfectly done, which takes about 40-45 minutes or until the pastry is puffed and golden brown. If it’s browning too quickly, tent loosely with foil.
- Rest before serving for at least 10 minutes to allow the filling to set. This makes for cleaner slices and prevents the filling from being too hot.
Notes
- For best results, make sure your mushroom mixture is completely cool before wrapping in pastry. A warm filling will make the pastry soggy and prevent proper puffing.
- The filling can be made a day ahead and refrigerated to save time on the day of serving.
- For extra flavor, you can add 2-3 tablespoons of nutritional yeast to the filling mixture.
- To make this gluten-free, look for gluten-free puff pastry and use gluten-free breadcrumbs and tamari instead of soy sauce.
- For a pretty presentation, you can score decorative patterns on the top pastry before baking, just be careful not to cut all the way through.

Common Mistakes to Avoid
- Not cooking mushrooms properly: Mushrooms release a lot of moisture when cooked. If you crowd the pan, they’ll steam instead of brown, resulting in a soggy filling. Work in batches for best results.
- Using warm filling: Always cool your filling completely before wrapping it in pastry. Warm filling will make the pastry soggy and prevent proper rising.
- Under-seasoning: Mushrooms absorb a lot of flavor. Be generous with your herbs and seasonings to create a rich, savory filling.
- Forgetting to vent: Without cuts in the top crust, steam gets trapped inside and can make the bottom soggy. Always cut a few vents.
- Skipping the resting period: Cutting into the wellington immediately after baking will result in filling that spills out. Allow at least 10 minutes of rest time.
Alternatives & Substitutions
- Mushroom varieties: Any sturdy mushrooms will work. Try oyster mushrooms or king oysters for different textures. Avoid white button mushrooms as they release too much water.
- Nut-free version: Replace walnuts with sunflower seeds or pumpkin seeds, or use extra breadcrumbs mixed with a tablespoon of olive oil.
- Herb substitutions: Dried herbs can work in a pinch—use 1 teaspoon dried for each tablespoon fresh. Sage and oregano also work well.
- Grain additions: Besides wild rice, try cooked quinoa, farro, or lentils mixed into the filling for added texture and protein.
- Puff pastry alternatives: While less traditional, you can use filo dough (layered with olive oil between sheets) or a homemade olive oil crust for a different texture.
FAQs
Can I make this Vegan Mushroom Wellington ahead of time?
You can prepare the filling up to 2 days ahead and store it in the refrigerator. You can also assemble the entire wellington a day before, cover it well with plastic wrap, and refrigerate. Just brush with the glaze right before baking, and you may need to add 5-10 minutes to the baking time if cooking from cold.
Why is my wellington soggy on the bottom?
This usually happens when the filling contains too much moisture or is warm when added to the pastry. Make sure to cook mushrooms thoroughly to evaporate excess moisture, cool the filling completely, and consider placing a thin layer of breadcrumbs on the bottom pastry before adding the filling to absorb any remaining liquid.
How do I serve Vegan Mushroom Wellington?
Slice it into thick pieces (about 1-1.5 inches) with a very sharp knife. Serve with roasted vegetables, mashed potatoes, and a rich mushroom or onion gravy for a complete meal. It also pairs beautifully with cranberry sauce for holiday dinners.
Can I freeze leftovers?
Yes! Slice cooled leftovers, wrap individual portions in parchment paper and then foil, and freeze for up to 3 months. Reheat in a 350°F (175°C) oven until warmed through, about 15-20 minutes. Avoid microwaving as it will make the pastry soggy.
Is there a shortcut version of this recipe?
For a quicker version, use a store-bought mushroom pâté or duxelles as part of your filling, reducing the amount of fresh mushrooms. You can also skip the food processor step and just chop the mushrooms finely, though the texture won’t be quite as cohesive.
