Ingredients

• 2 tablespoons olive oil
• 1 large yellow onion, finely chopped
• 4 garlic cloves, minced
• 500g mixed mushrooms (cremini, shiitake, portobello), finely chopped
• 1 tablespoon fresh thyme, chopped
• 1 tablespoon fresh rosemary, chopped
• 100g walnuts, finely chopped
• 2 tablespoons soy sauce or tamari for gluten-free
• 1 tablespoon Dijon mustard
• 1 sheet vegan puff pastry (about 250g), thawed
• 2 tablespoons vegan butter, melted
• Salt and pepper, to taste
• 2 tablespoons fresh parsley, chopped (optional, for garnish)

Equipment

• Large skillet or frying pan
• Mixing bowl
• Sharp knife and chopping board
• Baking tray
• Parchment paper
• Pastry brush
• Oven
• Food processor (optional, for chopping nuts and mushrooms)

Instructions

1. Prepare the mushroom filling: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
2. Add the mushrooms: Stir in the finely chopped mushrooms, thyme, and rosemary. Cook for 10-12 minutes, stirring occasionally, until the mushrooms release their moisture and become browned. This step is crucial to remove excess water so your Wellington doesn’t become soggy.
3. Incorporate walnuts and seasoning: Add the chopped walnuts and soy sauce to the mushroom mixture. Cook for 2-3 minutes, then season with salt and pepper to taste. Remove the skillet from heat and let the mixture cool slightly.
4. Prepare the puff pastry: Preheat your oven to 200°C (390°F). On a lightly floured surface, roll out your vegan puff pastry sheet to smooth any creases. Spread the Dijon mustard evenly over the pastry, leaving a 2 cm border around the edges.
5. Assemble the Wellington: Spoon the mushroom and walnut mixture onto the center of the pastry, shaping it into a rectangular log. Fold the pastry edges over the filling, sealing it completely, and tuck the ends underneath. Use a little water to help seal edges if needed.
6. Glaze and score: Transfer the wrapped Wellington onto a parchment-lined baking tray. Brush the surface with melted vegan butter to help it brown beautifully. Using a sharp knife, gently score the top of the pastry in a decorative pattern, being careful not to cut through.
7. Bake: Place the Wellington in the preheated oven and bake for 25-30 minutes or until the pastry is golden brown and crisp.
8. Rest and serve: Remove the Wellington from the oven and let it rest for 5-10 minutes before slicing. Garnish with fresh parsley if desired, then serve warm with your favorite sides.

Tips & Variations

For the best texture, be sure to finely chop the mushrooms and cook out all their moisture before assembling the Wellington.

Try adding chestnuts or cooked lentils to the filling for extra protein and texture.

If you’d like a gluten-free version, use a gluten-free vegan puff pastry available at specialty stores.

To add a layer of savory richness, try spreading a thin layer of vegan mushroom pâté or tapenade on the pastry before adding the filling.

For a seasonal twist, incorporate roasted butternut squash or caramelized shallots into the mushroom mixture.
