Why You'll Love This Recipe
About the Ingredients
1 lb (450g) cremini mushrooms, sliced
Cremini (baby bella) have deeper flavor than white. Use white mushrooms if you prefer a milder taste.
1/4 cup (60ml) fresh lemon juice
Freshly squeezed is key—bottled lacks brightness. Lime juice works too.
2 tbsp (30ml) tamari or soy sauce
Tamari is gluten-free. For a soy-free option, use coconut aminos.
1 clove garlic, minced
Fresh garlic packs a punch. Use a pinch of garlic powder in a pinch.
1/2 cup (120ml) raw cashews
Soak in water for 2 hours if you don't have a high-speed blender. Almonds or macadamias also work.
1/2 cup (120ml) water
Adjust to reach your desired consistency. Use more for a thinner soup.
1/4 cup (60ml) extra-virgin olive oil
Good olive oil adds fruitiness. Avocado oil is a neutral alternative.
1/2 small avocado, pitted
Adds creaminess and healthy fats. Omit for a lower-fat version.
1/2 tsp salt
Fine sea salt preferred. Adjust to taste, as tamari is salty.
1/4 tsp black pepper, freshly ground
White pepper gives a milder flavor if desired.
2 tbsp (8g) fresh chives, chopped (for garnish)
Optional but adds a mild oniony pop. Dill or parsley also work.
Tips & Tricks
- Slice mushrooms thinly and toss with lemon juice and tamari immediately—this begins the 'cooking' process via acid, softening them and drawing out flavor.
- Soak cashews ahead if your blender isn't high-speed; this ensures a silky smooth texture without grit.
- Chill the soup for at least 30 minutes before serving to allow flavors to meld—though it's delicious right away.
Pro Tips
Step-by-Step Instructions
1. Marinate the Mushrooms
In a medium bowl, combine sliced mushrooms, lemon juice, tamari, and minced garlic. Toss well and let sit for 10 minutes at room temperature. This acid marinade softens the mushrooms and infuses them with savory flavor.
2. Soak the Cashews
If you haven't pre-soaked, place cashews in a small bowl and cover with hot water. Let soak for 5 minutes, then drain. This quick soak softens them for blending.
3. Combine Soup Base
Transfer the marinated mushrooms and any liquid to a blender. Add soaked cashews, water, olive oil, avocado, salt, and pepper.
4. Blend Until Silky
Start on low and gradually increase to high. Blend for 2–3 minutes, or until completely smooth and creamy. Stop and scrape down the sides as needed.
5. Adjust Consistency
Check the thickness. If too thick, add water 1 tablespoon at a time and blend briefly. If too thin, add a few extra cashews or avocado and blend again.
6. Season to Taste
Taste the soup and adjust salt, pepper, or lemon juice. Remember that flavors will deepen as it sits.
7. Chill and Serve
Transfer to a bowl and refrigerate for at least 30 minutes, or serve at room temperature. Ladle into bowls and garnish with fresh chives and a drizzle of olive oil if desired.
Delicious Variations
Herbed
Add 1/4 cup fresh dill or basil before blending for a fresh, green note.
Spicy
Include 1/2 jalapeño (seeded) or a pinch of red pepper flakes for a kick.
Coconut Twist
Replace half the water with coconut milk and add a teaspoon of lime zest for a Thai-inspired flavor.
How to Store Raw Mushroom Soup
Refrigerator
Store in an airtight container for up to 3 days. Stir before serving; it may thicken—add a splash of water or lemon juice.
Freezer
Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge and blend again to restore creaminess.
Reheating
This soup is meant to be served cold or room temperature. If you prefer warm, gently heat in a saucepan over low heat, but do not boil to preserve raw enzymes.
