Mushroom Wellington, an exquisite main course that’ll make your Thanksgiving dinner a 5-star one. It is ready in just 30 minutes!


  • 1 pound mushrooms (450 g)
  • ½ cup walnuts (50 g)
  • 2 tbsp extra virgin olive oil
  • 1 onion, chopped
  • 4 cloves of garlic, sliced
  • ¼ cup red wine (60 ml)
  • 2 tbsp soy sauce or tamari
  • 1 tsp dried thyme
  • ½ tsp salt
  • ¼ tsp ground black pepper
  • 4 oz spinach (110 g)
  • 1 sheet of vegan puff pastry


  1. Preheat the oven to 400ºF or 200ºC and line a baking sheet with parchment paper.
  2. Add the mushrooms to a food processor and pulse until crumbly. Be careful not to over-process. Set aside.
  3. Also, add the walnuts to the food processor and pulse again until crumbly. Do not over-process. Set aside.
  4. Do the same with the spinach. You can also chop it with a knife if you want. Set aside.
  5. Heat the oil in a large skillet, add the onion and garlic, and cook over medium-high heat until they start to brown. 
  6. Add the mushrooms, walnuts, wine, and soy sauce, stir, and cook for 10 to 15 minutes or until most of the liquid has been released from the mushrooms and has evaporated. Stir occasionally.
  7. Incorporate the thyme, salt, pepper, and spinach, stir, and cook for 2 more minutes, stirring occasionally. The filling needs to be quite dry or it will become soggy inside the puff pastry, so cook it for longer if needed.
  8. Unroll the vegan puff pastry onto the lined baking sheet. Add the filling in the center third of the pastry. 
  9. Fold one side of the pastry over the filling, then the other side. 
  10. Carefully fold the pastry over the filling in a burrito style, rolling it from the long end and gently tucking in the ends as you roll. Brush the top of the crust with melted vegan butter or coconut oil.
  11. Bake for 35 to 40 minutes or until golden brown and puffed.
  12. Cut it with a sharp knife and serve your mushroom Wellington immediately with some vegan Thanksgiving sides, such as vegan biscuits, vegan mashed potatoes with vegan gravy or mushroom gravy, or even with a cozy pumpkin soup. You could also make some vegan biscuits with gravy!
  13. Keep the leftovers in the fridge for up to 5 days.


  • To make this vegan mushroom Wellington you can use any type of mushrooms, onions, or oil.
  • Feel free to customize your mushroom Wellington recipe by adding or omitting any spices or herbs you want.
  • If you don’t consume nuts, use sunflower seeds instead of walnuts.
  • Red wine can be replaced with vegetable stock.
  • I used soy sauce, but tamari is a good gluten-free alternative. If you don’t consume soy, coconut aminos is a great substitute. You could also add the same amount of water or vegetable stock and add more salt.
  • To make this vegan mushroom Wellington I used fresh spinach.
