  • 4 cloves garlic, minced
  • 1 tbsp fresh thyme, leaves
  • 1 tbsp fresh rosemary, finely chopped
  • Splash olive oil
  • Optional: Sprinkle salt
  • Optional: Sprinkle pepper
  • 1 large red onion, finely chopped
  • 1 cup white wine
  • 1/2 tbsp brown sugar
  • 2 cups chestnuts
  • 2 cups pecans
  • 2 slices seeded bread
  • 1/2 cup vegetable stock
  • 2 blocks short crust pastry
  • 1/2 cup soy milk

Method

22 steps
  1. Put the portobello mushrooms in a baking tray & cover in a splash of olive oil
  2. Sprinkle the rosemary, thyme, salt, pepper & garlic over the top of the mushrooms
  3. Bake at 200℃ (392℉) for 15 minutes & once they’re ready, set to one side to cool
  4. Put the red onion in a pan with olive oil & fry until it’s translucent
  5. Add the rosemary, thyme, salt, pepper & cook them together until they start sticking
  6. Add a cup of white wine & cook the alcohol off
  7. Add some brown sugar & mix it round so it caramelises, pour the mixture in a glass mixing bowl
  8. Put the chestnuts, pecans & bread in a food processor & whiz them all up into crumbs
  9. Add the crumbly mixture into the glass bowl with the onions & pour in the vegetable stock (gradually!)
  10. Stir the mixture round with a wooden spoon so it clumps up (it needs to feel like plasticine)
  11. Push 1 cm thick layer of the mixture onto a sheet of shortcrust pastry laid out on a baking tray
  12. Mould the mixture with your hands into a large, thin, wide sausage shape
  13. Put the pre cooked portobello mushrooms on top of the “sausage”
  14. Encase the mushrooms in the rest of the nutty mixture & smooth it out with your hands
  15. Carefully lay the second sheet of shortcrust pastry over the top of the nut roast mound
  16. Push the pastry down with your fingers
  17. Cut off the edges of the pastry with a pizza cutter or a very sharp knife & remove the excess
  18. Seal the edges with a fork
  19. Decorate your wellington with shapes cut out of the spare pastry & fork in air holes
  20. Bake at 200℃ (392℉) for 40 minutes, checking after 30 minutes and removing if it looks ready
  21. Use a bread knife to carve the Wellington into slices
  22. Serve with all the trimmings
