Not every food trend arrives with fanfare. Functional mushrooms entered mainstream consciousness quietly — through wellness podcasts, adaptogen supplements, and the slowly growing evidence base for their cognitive and immune benefits — before breaking decisively into food culture in 2026. Google search volume for “lion’s mane recipe” and “functional mushroom soup” grew by over 210 percent year-over-year. Pinterest wellness boards have featured mushroom-forward recipes prominently since late 2025.
What distinguishes functional mushrooms from the button mushrooms in your weekly shop is a matter of specific compounds. Lion’s mane (Hericium erinaceus) contains hericenones and erinacines — compounds studied for their role in stimulating nerve growth factor production, with potential implications for cognitive health and neurological protection. Reishi (Ganoderma lucidum) contains beta-glucan polysaccharides associated with immune modulation. Chaga and cordyceps have their own studied properties.
This soup brings lion’s mane and reishi together in a deeply savoury, aromatic broth that tastes — without any wellness-food caveats — genuinely excellent. Rich with miso, fragrant with ginger and garlic, and finished with a drizzle of truffle oil, it is a bowl of soup that nourishes the body and satisfies the palate in equal measure.
Ingredients (Serves 4)
- 200g fresh lion’s mane mushrooms (or 20g dried, rehydrated)
- 200g chestnut or shiitake mushrooms, thinly sliced
- 1 teaspoon reishi mushroom powder (from health food stores)
- 1 litre vegetable stock
- 500ml water
- 1 medium onion, finely diced
- 5 garlic cloves, minced
- 1 tablespoon fresh ginger, grated
- 2 tablespoons white miso paste
- 1 tablespoon soy sauce or tamari
- 1 tablespoon sesame oil
- 1 tablespoon neutral oil
- 1 teaspoon dried thyme
- 200ml oat cream or cashew cream (for richness)
- Fresh parsley and chives to serve
- Truffle oil, to finish (optional but transformative)
- Salt and white pepper
Method
Step 1: Heat neutral oil in a large pot over medium-high heat. Add the lion’s mane mushrooms and cook without stirring for three to four minutes until deeply golden. This caramelisation develops the soup’s primary flavour base. Remove and set aside.
Step 2: In the same pot, add sesame oil. Cook the sliced chestnut mushrooms over high heat for four to five minutes until golden. Add the onion, garlic, ginger, and thyme. Reduce heat and cook for seven minutes until aromatic.
Step 3: Add vegetable stock and water. Bring to a boil. Stir in the soy sauce and reishi powder. Simmer 15 minutes. Blend half the soup using an immersion blender, leaving the rest chunky for texture.
Step 4: Stir in the oat cream. Simmer gently for five more minutes. In a small bowl, whisk the miso paste with a ladleful of hot soup until smooth, then stir back into the pot (never add miso to boiling soup). Return the reserved lion’s mane mushrooms.
Step 5: Serve in warmed bowls. Finish with truffle oil, fresh herbs, and white pepper.
A note on sourcing: Fresh lion’s mane is increasingly available at farmers’ markets and specialty grocers. Dried versions are widely available online and require 20 minutes of rehydration in hot water. Reishi powder is available at most health food stores and online. Both have a mild flavour that does not dominate the soup.
