Mushroom & Chestnut Wellington with Turkey Seasoning

Golden Turkey Seasoning mushroom and chestnut Wellington with roasted carrots and green beans.

Despite its name, Turkey Seasoning is completely plant-based—and its rosemary, fennel, orange and garlic flavours are excellent with mushrooms. This golden Wellington uses Turkey Seasoning to give its chestnut filling the character of a traditional roast dinner.

The important step is cooking the mushrooms until dry, then cooling the filling completely. That keeps the pastry crisp and makes the Wellington easy to slice.

🧾 Ingredients

  • 1 tbsp olive oil
  • 1 onion, finely chopped
  • 500g chestnut mushrooms, finely chopped
  • 2 garlic cloves, chopped
  • 1½ tbsp Turkey Seasoning
  • 180g cooked chestnuts, roughly chopped
  • 100g baby spinach
  • 1 tbsp Dijon mustard
  • 1 x 320g sheet ready-rolled puff pastry, check vegan if required
  • 2 tbsp oat milk, for glazing
  • 1 tbsp sesame seeds, optional

🍴 Instructions

  1. Heat the oil in a large frying pan. Cook the onion for 6 minutes, then add the mushrooms and cook over medium-high heat for 12–15 minutes until their moisture has evaporated.
  2. Stir in the garlic and Turkey Seasoning for 1 minute. Add the chestnuts and spinach, cooking until the spinach wilts.
  3. Stir through the mustard, spread the filling on a tray and cool completely.
  4. Heat the oven to 200°C fan / 220°C conventional and line a baking tray.
  5. Unroll the pastry. Shape the filling into a compact log along the centre, fold over the pastry and seal the edges with oat milk. Place seam-side down.
  6. Score the top lightly, brush with oat milk and scatter with sesame seeds if using.
  7. Bake for 30–35 minutes until deeply golden. Rest for 10 minutes before slicing.
