Ingredients

• 500g mixed mushrooms (such as cremini, shiitake, and portobello), finely chopped
• 1 medium onion, finely chopped
• 3 garlic cloves, minced
• 2 tbsp olive oil
• 2 tbsp balsamic vinegar
• 1 tbsp fresh thyme leaves (or 1 tsp dried thyme)
• 1 tbsp fresh parsley, chopped
• 100g chestnuts, chopped (optional but adds great texture)
• 1 tbsp soy sauce or tamari (optional for extra umami)
• 1 sheet puff pastry (about 250-300g), thawed
• 1 tbsp Dijon mustard
• Salt and freshly ground black pepper, to taste
• Plant-based milk for brushing (optional, for vegan glaze)

Equipment

• Large frying pan or skillet
• Wooden spoon or spatula
• Mixing bowl
• Baking sheet
• Parchment paper
• Knife and chopping board
• Brush for glazing
• Rolling pin (optional, if you need to roll out puff pastry)

Instructions

1. Prepare the mushroom filling: Heat the olive oil in a large frying pan over medium heat. Add the finely chopped onion and sauté for 3-4 minutes until translucent.
2. Add garlic and mushrooms: Stir in the minced garlic and cook for another minute until fragrant. Add the chopped mushrooms and chestnuts, if using. Cook the mixture for about 10 minutes, stirring frequently, until most of the moisture has evaporated and the mushrooms are tender.
3. Season and flavor: Stir in the balsamic vinegar, thyme, parsley, soy sauce (if using), salt, and pepper. Cook for an additional 2-3 minutes to let the flavors meld together. Remove from heat and let the mixture cool completely.
4. Prepare the pastry: Preheat your oven to 200°C (390°F). Line a baking sheet with parchment paper. Roll out the puff pastry on a lightly floured surface if needed, to a rectangle about 30x25cm.
5. Assemble the Wellington: Spread the Dijon mustard evenly over the surface of the puff pastry. Spoon the cooled mushroom mixture down the center of the pastry, shaping it into a log.
6. Wrap the pastry: Fold the long sides of the pastry over the mushroom filling, overlapping slightly to seal. Pinch the edges to seal the Wellington completely. Trim any excess pastry if needed. Place the wrapped Wellington seam-side down on the prepared baking sheet.
7. Glaze and decorate: Brush the top of the Wellington with plant-based milk (or regular milk if not vegan) to encourage golden browning. Optional: use pastry scraps to decorate the top with leaves or patterns, then brush again with milk.
8. Bake: Bake in the preheated oven for 25-30 minutes or until the pastry is golden and crisp.
9. Rest and serve: Remove from the oven and let the Wellington rest for 5-10 minutes before slicing. This helps the filling set and makes it easier to cut.

Tips & Variations

For a richer filling, try adding finely chopped walnuts or pecans with the mushrooms to add texture and flavor.

To make this recipe vegan, ensure your puff pastry is dairy-free and use a plant-based milk for glazing.

If you want to add more layers of flavor, consider spreading a thin layer of sautéed spinach or caramelized onions under the mushroom mixture before wrapping.

For an extra touch of indulgence, add a layer of vegan cream cheese or cashew cheese inside the Wellington.

Don’t forget to let the mushroom mixture cool completely before wrapping it in pastry to prevent sogginess.
