Ingredients You’ll Need
For the Mushroom Filling
- 2 tbsp olive oil
- 1 onion, finely chopped
- 3 cloves garlic, minced
- 16 oz mushrooms (cremini, portobello, or a mix), finely chopped
- 1 tbsp soy sauce or tamari
- 1 tsp thyme
- ½ tsp smoked paprika
- Salt & pepper to taste
- Optional: ½ cup walnuts, chopped (for texture)
For the Wellington
- 1 sheet vegan puff pastry, thawed
- 2 tbsp plant-based milk (for brushing)
- Optional: fresh parsley for garnish
Step-by-Step Instructions
- Prep the filling
Heat olive oil in a pan. Sauté onions until soft, then add garlic. Stir in chopped mushrooms, soy sauce, thyme, smoked paprika, salt, and pepper. Cook until moisture evaporates. Stir in walnuts if using. - Roll out the puff pastry
Lightly flour your surface and roll out the pastry to fit your filling. - Assemble the Wellington
Spoon the mushroom mixture in a log down the center of the pastry. Fold over the sides, pinch the ends, and seal. Brush the top with plant-based milk. - Bake
Preheat the oven to 400°F (200°C). Bake for 25–30 minutes or until golden brown and puffed. - Serve
Let it rest a few minutes, slice carefully, garnish with parsley, and serve warm.
Common Mistakes to Avoid
- Overfilling the pastry — it may burst.
- Not draining mushrooms — too much moisture = soggy pastry.
- Skipping the milk brush — golden top is worth it.
- Cutting too soon — Wellington needs a few minutes to settle.
Alternatives & Substitutions
- Swap mushrooms for roasted root vegetables or eggplant for a twist.
- Add a layer of vegan cream cheese or cashew cheese for extra creaminess.
- Use gluten-free puff pastry if needed — handle gently.
This dish also makes a show-stopping centerpiece for Meatless Fridays or holiday dinners.
