How to Make Vegan Walnut Mushroom Wellington
-
Prepare the Mushroom Filling:
Start by chopping your mushrooms and sautéing onions in oil or vegan butter until they’re caramelized, which should take about 5 minutes. Then, add garlic, thyme, and rosemary, and let everything sauté until fragrant, about 1 minute. Incorporate the mushrooms, walnuts, salt, black pepper, and chili powder, cooking until the water evaporates. Finally, mix in the spinach and nutritional yeast and cook until wilted. Allow to cool to room temperature. -
Shape the Filling:
Once cooled, transfer the mixture onto a piece of plastic wrap and form it into a log shape. Tightly wrap it up and refrigerate for at least 1 hour to help it firm up. -
Prepare the Pastry:
Roll out your thawed puff pastry on a lightly floured surface. Place the filling log on one edge of the pastry. Brush the edges with dijon mustard, fold over the pastry, and roll it into a log shape, pinching the ends to seal securely. -
Decorate and Bake:
Make decorative scores on the top of the wellington and brush it with a mixture of maple syrup and oat milk for a beautiful glaze. Bake at 400°F (200°C) for 25-30 minutes, or until the pastry achieves a stunning golden brown color. -
Serve:
Let the finished wellington cool slightly before slicing. It’s delightful served with vegan gravy or cranberry sauce on the side for that extra festive touch.
Optional: Garnish with fresh thyme for an aromatic finish.

Expert Tips for Vegan Wellington
-
Caramelization Perfection: Ensure you constantly stir the onions while caramelizing to achieve a sweet, golden color without burning.
-
Cool Before Wrapping: Allow the mushroom filling to cool completely before wrapping in pastry. This prevents a soggy Vegan Wellington.
-
Sealing Secrets: When rolling the pastry, create a tight seal at the ends to maintain the shape during baking and prevent any filling from leaking out.

Flavor Enhancements: Feel free to mix in additional spices or a dash of balsamic vinegar to your filling, enhancing the savory profile of this comforting dish.
Make Ahead Options
Preparing this Vegan Walnut Mushroom Wellington in advance is a game changer for busy weeknights or festive gatherings! You can make the filling up to 3 days ahead. Simply cook the mushroom mixture, let it cool completely, then shape it into a log with plastic wrap and refrigerate. For even greater ease, you can assemble the wellington completely and freeze it uncooked for up to 1 month. Just remember to thaw it in the refrigerator overnight before baking, so the pastry retains its flaky texture. When you’re ready to enjoy, brush with the maple syrup and oat milk mixture and bake it directly from the fridge, ensuring every bite tastes just as delicious as when freshly made!
How to Store and Freeze Vegan Wellington
Fridge: Keep the cooked Vegan Walnut Mushroom Wellington in an airtight container for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through for the best texture.
Freezer: For longer storage, wrap the unbaked wellington tightly in plastic wrap and then in foil. It can be frozen for up to 3 months. Thaw in the fridge overnight before baking.
Reheating: For leftover baked wellington, reheat in the oven at 350°F (175°C) for about 20-25 minutes or until heated through. This helps restore its flaky texture.

Vegan Walnut Mushroom Wellington with Caramelized Onions Recipe FAQs
What is the best way to choose mushrooms for this recipe?
Absolutely! When selecting mushrooms, look for ones that are firm, plump, and free from dark spots or blemishes. Varieties like shiitake or cremini offer excellent umami flavor and moisture. If you notice dark spots all over, they may be past their prime. Remember, fresher mushrooms will enhance the overall taste of your Vegan Walnut Mushroom Wellington.
How do I store leftover Vegan Wellington?
Very simply! Store your cooked Vegan Walnut Mushroom Wellington in an airtight container in the refrigerator for up to 3 days. For the best texture, I recommend reheating in the oven at 350°F (175°C) until warmed through, approximately 20-25 minutes, to keep that delightful crunch on the outside.
Can I freeze the Vegan Wellington before baking?
Absolutely! To freeze your unbaked Vegan Walnut Mushroom Wellington, wrap it tightly in plastic wrap and then in foil to protect it from freezer burn. It’s best used within 3 months. When you’re ready to bake, thaw it in the fridge overnight before popping it in the oven to bake as per the instructions.
What if my filling is too wet?
No worries! If your filling is too wet, it might make for a soggy pastry. To fix this, cook the mixture a bit longer before wrapping it in the pastry. Allow it to evaporate on medium heat until moisture is reduced, and let it cool before wrapping to help firm it up. You can also add a small amount of breadcrumbs or ground walnuts to help absorb excess moisture.
Is this recipe suitable for those with nut allergies?
Great question! The walnuts in the filling can absolutely be substituted with seeds such as sunflower or pumpkin seeds for those with nut allergies. This will maintain a crunchy texture while keeping the dish nut-free! Always check for cross-contact if you’re serving someone with severe allergies.
How long can the mushroom filling be prepared in advance?
Definitely! The mushroom filling can be prepared and stored in the refrigerator for up to 2 days before assembling the wellington. Just make sure it’s entirely cooled before storing it in an airtight container. This makes preparation stress-free on the day you plan to enjoy your Vegan Walnut Mushroom Wellington!
