Ingredients Overview

Mushrooms

Choose a mix of cremini, baby bella, or even wild mushrooms for depth of flavor. Each variety offers slightly different earthy notes — cremini bring a mellow savoriness, while shiitakes introduce a smoky undertone. Avoid white button mushrooms alone; they lack the richness needed for a bold base.

Tips:

• Clean mushrooms with a damp cloth instead of rinsing to prevent them from becoming waterlogged.

• Slice evenly to ensure uniform cooking.

Aromatics: Onion, Garlic, Thyme

A yellow or sweet onion lends subtle sweetness, while garlic adds pungency. Fresh thyme rounds it out with herbal warmth. These build the foundation of the soup’s flavor.

Alternatives:

• Leeks instead of onions for a more delicate taste.

• Rosemary or sage as herbal substitutes.

Plant-Based Cream

The key to achieving a creamy texture is blending soaked cashews or adding full-fat coconut milk. Cashew cream is neutral and silky, ideal if you don’t want a coconut aroma.

Options:

• Soy cream or oat milk for nut-free versions.

• Almond milk thickened with a roux (flour + oil) for added body.

Vegetable Broth

Use a high-quality, low-sodium vegetable broth. Homemade is ideal, but store-bought works well if it’s not overly salty.

Olive Oil or Vegan Butter

Sautéing the mushrooms and aromatics in olive oil brings out their richness. Vegan butter can add a buttery aroma if desired.

Nutritional Yeast (Optional)

Adds a savory, cheesy undertone without dairy — perfect for enhancing umami.

Step-by-Step Instructions

1. Sauté the Aromatics

   Heat olive oil or vegan butter in a large pot over medium heat. Add finely chopped onion and cook until translucent, about 5 minutes. Stir in minced garlic and thyme, and cook for another 1–2 minutes until fragrant.

2. Cook the Mushrooms

   Add the sliced mushrooms to the pot. Let them cook undisturbed for a few minutes to brown. Stir occasionally, cooking until their moisture has mostly evaporated and they begin to caramelize — about 10 minutes.

   Chef’s Tip: Don’t overcrowd the pan. If necessary, cook mushrooms in batches to get that golden sear.

3. Deglaze and Simmer

   Pour in a splash of vegetable broth to deglaze the pot, scraping up any browned bits for added flavor. Add the rest of the broth, a pinch of salt, and freshly ground black pepper. Bring to a simmer and cook for 15–20 minutes, allowing flavors to meld.

4. Add Creamy Element

   Lower the heat and stir in your plant-based cream of choice (cashew, coconut, or oat). Simmer gently for 5 minutes. If using coconut milk, taste and adjust salt to balance sweetness.

5. Blend to Desired Texture

   Use an immersion blender to partially blend the soup directly in the pot. For a smoother soup, transfer to a high-speed blender and purée completely. Leave some mushroom pieces for texture, if you like.

   Safety Note: Let the soup cool slightly before transferring to a blender to avoid steam pressure build-up.

6. Finish and Serve

   Taste and adjust seasoning. Add more thyme or a dash of white pepper if desired. Ladle into bowls, drizzle with olive oil or a spoonful of vegan cream, and top with fresh herbs or toasted croutons.

FAQs

Q1: Can I freeze vegan cream of mushroom soup?

A1: Yes, you can freeze it, but results vary by cream type. Cashew-based versions freeze well without separating. Coconut milk may slightly change in texture, but it’s still tasty. Let the soup cool fully before storing in an airtight container for up to 2 months.

---

Q2: What mushrooms are best for cream of mushroom soup?

A2: Cremini and baby bella mushrooms are ideal for their rich, earthy flavor. Add shiitake or a few dried porcini mushrooms for complexity. Avoid white button mushrooms alone as they lack depth.

---

Q3: How do I make the soup thicker?

A3: For a thicker soup, simmer longer to reduce the broth. You can also add 1 tablespoon flour during the sauté phase or blend in more cashew cream. A small potato or some cauliflower florets can also be simmered and blended for body.

---

Q4: Is this soup gluten-free?

A4: It can be! Use a certified gluten-free broth and avoid flour-based thickeners. Cashew or coconut milk are naturally gluten-free, making them great options for a celiac-friendly version.

---

Q5: What can I use instead of cashew cream?

A5: Full-fat coconut milk is a common alternative. Oat milk or soy milk work too, especially if thickened slightly with cornstarch. Silken tofu blended with broth is another creamy, nut-free substitute.

---

Q6: Can I make it oil-free?

A6: Yes. Sauté the aromatics and mushrooms in a splash of vegetable broth or water instead of oil. While it slightly reduces depth of flavor, the soup will still be delicious and low-fat.

---

Q7: How long does it keep in the fridge?

A7: Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors often deepen overnight, making it even tastier the next day. Reheat gently on the stove or in the microwave.
