Step-by-Step Guide for Vegan Mushroom Wellington
1. Prepare the Filling
Finely chop 500g mushrooms, 1 onion, and 2 garlic cloves. Heat a little oil in a pan, then cook everything over medium heat until soft and most of the moisture has evaporated. Season with salt, pepper, and thyme.
2. Cool the Mixture
Remove the mushroom filling from the heat and let it cool completely. This helps prevent the pastry from becoming soggy during baking.
3. Assemble the Wellington
Roll out a sheet of vegan puff pastry on a floured surface. Spoon the cooled mushroom mixture into the center, shaping it into a log. Fold the pastry over the filling and seal the edges tightly.
4. Bake Until Golden
Place the Wellington seam-side down on a lined baking tray. Brush the top with plant milk for a golden finish. Cut a few small slits on top for steam to escape. Bake at 200°C (400°F) for 30–35 minutes.
5. Serve and Enjoy
Allow the Wellington to rest for 5 minutes before slicing. Serve with roasted vegetables, mashed potatoes, or gravy for a delicious meal.
