Ingredients for Creamy Mushroom Soup
Here’s what you’ll need to make this soup a success:
-
2 tablespoons (30 ml) olive oil
-
1 large yellow onion, finely chopped
-
2 cloves garlic, minced
-
1 pound (450g) mixed mushrooms (cremini, shiitake, oyster), sliced
-
1/2 teaspoon dried thyme
-
1/4 teaspoon ground nutmeg
-
4 cups (950ml) low-sodium vegetable broth
-
1 cup (240ml) heavy cream
-
1/4 cup (30g) all-purpose flour
-
1/4 cup (60ml) dry sherry (optional, but highly recommended!)
-
Salt and freshly ground black pepper, to taste
-
Fresh parsley, chopped (optional garnish)
-
Crispy croutons (optional garnish)
-
A swirl of heavy cream (optional garnish)
Kitchen Equipment You’ll Need
To prepare this soup seamlessly, gather the following:
-
Large soup pot or Dutch oven
-
Chef’s knife and cutting board
-
Wooden spoon or silicone spatula
-
Immersion blender (or standard blender for puréeing)
-
Ladle
-
Measuring cups and spoons
Step-by-Step Directions
1. Sauté the Aromatics
Begin by heating the olive oil in a large pot over medium heat. Add the chopped onion and minced garlic, and sauté until they become soft and translucent—about 5 minutes. This step builds a fragrant base for the soup.
2. Cook the Mushrooms
Next, add your sliced mushrooms to the pot, along with the dried thyme and nutmeg. Stir occasionally and cook for 8–10 minutes, allowing the mushrooms to soften and release their rich juices.
3. Make the Roux
Sprinkle the flour evenly over the mushroom mixture. Stir constantly for 1–2 minutes to cook the flour and form a light roux. This will naturally thicken your soup without needing additional starch.
4. Deglaze with Sherry
Pour in the dry sherry, scraping up the browned bits from the bottom of the pot. This adds depth and complexity to the soup. Let it simmer for a minute or two to cook off the alcohol.
5. Add Broth and Simmer
Gradually pour in the vegetable broth while stirring to prevent lumps. Once fully incorporated, bring the mixture to a gentle simmer and reduce the heat. Let the soup simmer uncovered for 20 minutes so the flavors can meld.
6. Blend the Soup
Use an immersion blender to purée the soup until smooth. If you’re using a regular blender, work in small batches and vent the lid to avoid pressure build-up.
7. Stir in the Cream
Return the soup to the pot (if you used a blender) and stir in the heavy cream. Warm gently until heated through, but do not let it boil.
8. Season and Serve
Taste and season with salt and freshly ground black pepper. Ladle the soup into bowls and garnish with fresh parsley, crunchy croutons, and an elegant swirl of cream if desired.
Expert Tips for Perfect Soup
-
Use a mix of mushrooms for the most depth. Cremini offers earthiness, shiitake adds smokiness, and oyster lends sweetness.
-
Don’t skip the roux—it thickens the soup and enhances mouthfeel.
-
For extra umami, add a teaspoon of white miso paste or a dash of soy sauce.
-
Want it vegan? Swap the heavy cream for canned full-fat coconut milk or a cashew cream blend.
-
Short on time? Use pre-sliced mushrooms to cut down prep.
Storage & Leftovers
This mushroom soup stores beautifully:
-
Fridge: Store in an airtight container for up to 4 days.
-
Freezer: Cool completely, transfer to freezer-safe containers, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
When reheating, do so gently over medium heat. Avoid boiling, especially if using cream, to prevent curdling.
Recipe Variations
-
Mushroom Barley Soup: Add 1/2 cup cooked barley for a heartier bite.
-
Spicy Kick: Stir in a pinch of red pepper flakes during sautéing.
-
Herby Upgrade: Finish with a drizzle of truffle oil or garnish with fried sage leaves for restaurant-style flair.
-
Low-Carb Option: Omit the flour and use a splash of cream for a thinner but still delicious soup.

Frequently Asked Questions (FAQ)
Q: Can I make this mushroom soup ahead of time?
Yes! This soup tastes even better the next day as the flavors deepen. Just reheat gently.
Q: Is there a gluten-free alternative to flour for thickening?
Absolutely. Try using cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water) or a gluten-free flour blend.
Q: What mushrooms work best?
A combination of cremini, shiitake, and oyster mushrooms creates a rich, complex flavor. However, you can use any mushrooms you have on hand, including white button or portobello.
Q: Do I have to blend the soup?
No! If you prefer a chunkier texture, skip the blending step or only partially blend.
Q: Can I freeze mushroom soup with cream?
Yes, but cream can sometimes separate. For best results, freeze the soup before adding cream, then stir it in when reheating.
