Ingredients Overview

Each ingredient in this soup plays a key role in building layers of flavor and creating that silky, luscious texture.

Fresh Mushrooms (White Button or Cremini)

The star of the dish. Use a mix for depth—white button for mild flavor, and cremini (baby bella) for meatiness.

Optional Upgrade: Add shiitake, oyster, or wild mushrooms for complexity.

Tip: Slice mushrooms evenly for consistent browning and better texture.

Onion & Garlic

Essential aromatics that bring sweetness and warmth to the base.

Variation: Add a shallot or a leek for a more delicate flavor.

Butter and Olive Oil

Used to sauté the mushrooms and aromatics. Butter adds richness, while olive oil prevents scorching.

All-Purpose Flour

Creates the roux to thicken the soup. When whisked into butter, it forms the silky base that carries the cream.

Substitute: Use gluten-free flour or cornstarch slurry for a GF version.

Vegetable or Chicken Broth

Gives the soup body and infuses it with savory depth.

Tip: Use low-sodium broth so you can adjust seasoning yourself.

Heavy Cream or Half-and-Half

Adds creamy texture and rich flavor. Heavy cream creates a thicker soup; half-and-half is lighter but still velvety.

Dairy-Free Option: Use coconut cream or cashew cream for similar richness.

Fresh Thyme and Bay Leaf

Herbs add a subtle woodsy and earthy background note.

Optional: Finish with chopped parsley or chives for brightness.

Step-by-Step Instructions

This soup takes less than 45 minutes start to finish, and it’s mostly hands-off once the mushrooms are sautéed and the broth simmers.

1. Sauté the Mushrooms

In a large soup pot or Dutch oven, melt:

• 2 tbsp butter

• 1 tbsp olive oil

Add:

• 1 lb mushrooms, sliced

• 1 small onion, diced

• 2 cloves garlic, minced

Cook over medium-high heat for 10–12 minutes, stirring occasionally, until mushrooms are browned and most of their moisture has evaporated.

---

2. Add Flour and Herbs

Sprinkle in:

• 3 tbsp all-purpose flour

Stir well to coat mushrooms and cook the flour for 1–2 minutes, until it smells slightly nutty.

Add:

• 1 tsp fresh thyme (or ½ tsp dried)

• 1 bay leaf

---

3. Add Broth and Simmer

Slowly whisk in:

• 4 cups vegetable or chicken broth

Bring to a gentle boil, then reduce to low and simmer 10–15 minutes, stirring occasionally, until slightly thickened.

---

4. Stir in Cream

Reduce heat to low and stir in:

• 1 cup heavy cream or half-and-half

Simmer for 5 more minutes without boiling to avoid curdling. Remove bay leaf.

Taste and season with:

• Salt and freshly ground black pepper

---

5. Blend (Optional)

For a silky texture, blend all or part of the soup:

• Fully blended: Use an immersion blender directly in the pot for a smooth finish.

• Half-blended: Blend 2 cups of soup and stir it back in to keep some chunkiness.

Expert Tips

Flavor Variations

• Add a splash of dry white wine or sherry after sautéing mushrooms for extra depth.

• Top with truffle oil or crispy shallots for an upscale twist.

Substitutions

• Vegan: Use plant-based butter, broth, and coconut or cashew cream.

FAQs

Q1: Can I freeze cream of mushroom soup?

A2: Use olive oil instead of butter, and substitute coconut cream, cashew cream, or oat cream for heavy cream.

Q3: Can I use canned mushrooms?
A3: Fresh mushrooms give far better texture and flavor. Canned mushrooms are okay in a pinch but won’t brown or caramelize.

Q4: How do I make this soup thicker?
A4: Simmer longer after adding broth, or add an extra tablespoon of flour. You can also puree part of the soup for a thicker feel.

Q5: Can I use this as a base for casseroles?
A5: Yes! Let the soup cool and thicken slightly more. Use it in place of canned cream of mushroom in recipes like green bean casserole or chicken bakes.

Q6: How long does it last in the fridge?
A6: Store in an airtight container for up to 4 days. Reheat gently on the stove, stirring frequently.

Q7: Can I make this in advance?
