How To Make Hairy Bikers Veggie Wellington Recipe
- Cook the vegetables: Sauté the onion, carrots, and celery in olive oil until soft. Add the garlic and thyme and cook for another minute.
- Prepare the mushrooms: In a separate pan, cook the chopped mushrooms until all the moisture has evaporated and they’re nicely browned.
- Mix the filling: Combine the cooked vegetables, mushrooms, chestnuts, lentils, walnuts, soy sauce, vegetable stock, and breadcrumbs in a large bowl. Mix well and let the filling cool completely.
- Assemble the Wellington: Roll out the puff pastry sheet and place the cooled filling in a log shape down the center. Brush the edges with the beaten egg.
- Wrap and seal: Fold the pastry over the filling and seal the seams well. Place seam-side down on a baking sheet.
- Bake: Brush the top with egg wash and bake at 400°F (200°C) for 35-40 minutes until golden brown and crisp.

Recipe Tips
- How to avoid a soggy bottom: Make sure the mushroom mixture is dry and the filling is cooled before wrapping in pastry.
- Can I make this ahead of time? Yes, assemble it up to a day in advance and refrigerate. Add egg wash just before baking.
- What mushrooms work best? Cremini mushrooms offer a deep, savory flavor but you can also mix in shiitake or portobello.
- How to toast walnuts: Bake at 350°F for about 5-7 minutes until fragrant, then chop.
- Is it freezer-friendly? Yes, freeze unbaked Wellington wrapped well; bake from frozen, adding extra time.
