Ingredients  

  • 20 g dried ceps aka porcini
  • 1 L hot vegetable stock
  • 1 medium onion chopped
  • 1 small leek sliced
  • 2 garlic cloves, minced
  • 2 tbsp olive oil or butter
  • 200 g cooked chestnuts
  • 150 g potato diced
  • 1 tsp thyme leaves or ½ tsp dried
  • 1 tbsp soy sauce
  • 100 ml cream or oat cream
  • Salt and black pepper

Instructions 

  • Soak the ceps in 400 ml boiling water for 15–20 min. Strain through a fine sieve, keep the liquid, and chop the mushrooms.
  • Dice the potato, chop onion and leek, crush garlic, and strip thyme leaves.
  • Heat oil or butter in a large pot. Add onion, leek, and garlic; cook gently for 6–8 min until soft but not browned.
  • Stir in the ceps and thyme and cook for 2 min until fragrant.
  • Add chestnuts, potato, soy sauce, cep liquid, and stock. Bring to a boil, then simmer for about 25 min until everything is tender.
  • Blend until smooth, stir in cream, and season to taste. Add a splash of water or stock if too thick.
  • Serve with a drizzle of truffle oil or thyme butter and some crusty bread.

Notes

This creamy cep and chestnut soup is naturally gluten-free and easy to adapt for any diet. For a vegan or dairy-free version, use olive oil instead of butter and oat cream in place of dairy cream — it stays velvety and light.
To make it higher in protein, replace the potato with a handful of cooked white beans or lentils before blending. They thicken the soup and add extra substance without changing the flavour too much.
For a touch of richness, finish with truffle oil or thyme butter, or keep it simple with a swirl of good olive oil and fresh herbs.
Storage: The soup keeps well in the fridge for up to 3 days and freezes for up to 3 months. Reheat gently on the stove, adding a splash of water or stock if it thickens. Add any cream or butter after reheating for the best texture.
