Ingredients

  • 400g mixed mushrooms (chestnut, cremini, shiitake), finely chopped
  • 100g cooked chestnuts, chopped
  • 1 large onion, finely diced
  • 2 garlic cloves, minced
  • 100g cooked lentils (brown or green)
  • 100g fresh spinach, roughly chopped
  • 1 tbsp soy sauce or tamari
  • 1 tbsp olive oil
  • 2 tsp fresh thyme, chopped (or 1 tsp dried thyme)
  • 1 tsp fresh rosemary, chopped
  • Salt and freshly ground black pepper, to taste
  • 1 sheet of puff pastry (about 320g), thawed if frozen
  • 1 tbsp Dijon mustard
  • Plant-based milk, for brushing (optional)

Equipment

  • Large frying pan or skillet
  • Mixing bowl
  • Wooden spoon or spatula
  • Chopping board and sharp knife
  • Baking tray lined with parchment paper
  • Pastry brush
  • Rolling pin (optional)
  • Oven preheated to 200°C (390°F)

Instructions

  1. Prepare the mushroom filling: Heat the olive oil in a large frying pan over medium heat. Add the diced onion and sauté for about 5 minutes until soft and translucent.
  2. Add the minced garlic, chopped mushrooms, and chestnuts. Cook for 10-12 minutes, stirring frequently, until the mushrooms release their moisture and it evaporates, leaving a rich, dry mixture.
  3. Stir in the cooked lentils, soy sauce, fresh thyme, rosemary, salt, and pepper. Cook for another 3-4 minutes to combine the flavors.
  4. Add the chopped spinach and cook until just wilted. Remove from heat and transfer the mixture to a bowl to cool completely. Cooling is essential to avoid soggy pastry later.
  5. Prepare the puff pastry: Roll out the puff pastry on a lightly floured surface to a rectangle about 30x25cm (12×10 inches). If your pastry sheet is already rolled, simply lay it out on your baking tray lined with parchment paper.
  6. Once the filling has cooled, spread the Dijon mustard evenly over the center of the puff pastry, leaving a 3cm (1 inch) border around the edges.
  7. Place the cooled filling in a log shape along the mustard-coated center of the pastry.
  8. Carefully fold the pastry over the filling from the long edges to encase it completely. Pinch the edges to seal and tuck in the ends, trimming any excess pastry if needed.
  9. Turn the Wellington seam-side down on the parchment paper. Brush the top with plant-based milk for a beautiful golden finish.
  10. Optionally, score the top of the pastry gently with a sharp knife to create a decorative pattern, being careful not to cut all the way through.
  11. Bake in the preheated oven for 25-30 minutes or until the pastry is puffed and golden brown.
  12. Remove from the oven and let it rest for 10 minutes before slicing. This allows the filling to set slightly, making it easier to cut.

Tips & Variations

For an extra flavor boost, try adding a layer of caramelized onions or a smear of vegan pâté under the filling before wrapping in pastry.

If you want a nutty crunch, toss in some toasted walnuts or pecans with the mushrooms.

Use gluten-free puff pastry if you need to keep this dish gluten-free.

Leftovers can be reheated gently in the oven or enjoyed cold the next day.
