Essential Ingredients
For the mushroom base:
- 2 pounds mixed fresh mushrooms (cremini, shiitake, and button mushrooms)
- 1/2 ounce dried porcini mushrooms
- 3 tablespoons butter
- 2 tablespoons olive oil
- 1 large onion, finely diced
- 3 cloves garlic, minced
- 1/4 cup dry white wine or dry sherry
- 3 tablespoons all-purpose flour
For the soup base:
- 4 cups vegetable or chicken broth
- 2 sprigs fresh thyme
- 1 bay leaf
- 1 teaspoon salt (or to taste)
- 1/2 teaspoon black pepper
- 1/2 cup heavy cream
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon fresh chives, chopped
Preparing the Mushroom Foundation
Start by rehydrating the dried porcini mushrooms in 1 cup of hot water for about 15 minutes. These dried mushrooms will add incredible depth and richness to your soup that fresh mushrooms alone cannot achieve. Once softened, remove the porcini and chop them finely, but don’t discard the soaking liquid. Strain this liquid through a fine-mesh sieve or coffee filter to remove any grit, as you’ll use it to enhance the soup’s flavor.
Clean your fresh mushrooms by wiping them with a damp paper towel rather than rinsing them under water, which can make them soggy and prevent proper browning. Remove any tough stems and slice the mushrooms into uniform pieces about 1/4 inch thick. Using a mix of mushroom varieties creates a more complex flavor profile than using just one type.
Building Deep Mushroom Flavors
Heat a large, heavy-bottomed pot or Dutch oven over medium-high heat. Add 2 tablespoons of butter and 1 tablespoon of olive oil. The combination of butter and oil prevents the butter from burning while still providing rich flavor. Add half of the sliced mushrooms to the pot, making sure not to overcrowd them, which would cause them to steam rather than brown.
Cook the mushrooms without stirring for 3-4 minutes, allowing them to develop a beautiful golden-brown color on one side. This browning process, called the Maillard reaction, creates hundreds of new flavor compounds that give your soup its distinctive taste. Stir and continue cooking for another 2-3 minutes until the mushrooms are golden brown all over. Remove the first batch and repeat with the remaining mushrooms.
Creating the Aromatic Base
In the same pot, add the remaining butter and olive oil if needed. Add the diced onion and cook for 4-5 minutes until it becomes translucent and fragrant. The onion should be soft but not browned, as you want it to provide sweetness rather than caramelized flavors that might compete with the mushrooms.
Add the minced garlic and chopped rehydrated porcini mushrooms to the pot, cooking for about 1 minute until the garlic becomes fragrant. Be careful not to let the garlic burn, as this would add bitterness to your soup.
Deglazing and Thickening
Pour in the white wine or sherry, scraping up any browned bits from the bottom of the pot with a wooden spoon. These browned bits are packed with flavor and will dissolve into the liquid, adding richness to your soup. Let the wine simmer for 2-3 minutes to cook off the alcohol and concentrate the flavors.
Sprinkle the flour over the mixture and stir constantly for 2 minutes to create a light roux. This flour will help thicken your soup and prevent it from being too thin. The roux should smell nutty and toasted but shouldn’t brown significantly.
Building the Soup Base
Gradually add the broth and the reserved mushroom soaking liquid, stirring constantly to prevent lumps from forming. Return all the browned mushrooms to the pot along with the fresh thyme sprigs and bay leaf. These herbs will infuse the soup with subtle aromatic notes that complement the earthy mushroom flavors.
Bring the soup to a boil, then reduce the heat to low and simmer partially covered for 20-25 minutes. This simmering time allows the flavors to meld together and gives the flour time to fully thicken the soup. Stir occasionally to prevent sticking and ensure even cooking.
Achieving the Perfect Creamy Texture
Remove the thyme sprigs and bay leaf from the soup and discard them. At this point, you can choose to leave the soup chunky for a rustic texture, or partially blend it for a smoother consistency. If you prefer a smoother soup, use an immersion blender to blend about half the soup, leaving some mushroom pieces for texture.
Season the soup with salt and pepper, tasting and adjusting as needed. Remember that the mushrooms and broth already contain some salt, so add gradually. The soup should have a rich, earthy flavor with balanced seasoning that doesn’t overpower the mushroom taste.
Adding the Luxurious Cream Finish
Remove the soup from heat and slowly stir in the heavy cream. Adding the cream off the heat prevents it from curdling due to high temperatures. The cream should be fully incorporated, creating a beautiful, pale tan color throughout the soup.
Return the pot to very low heat just to warm the soup through, but don’t let it boil once the cream has been added. Boiling can cause the cream to separate and create an unpleasant texture.
Final Touches and Presentation
Stir in the fresh chopped parsley and chives just before serving. These fresh herbs add a bright pop of color and fresh flavor that balances the richness of the cream and mushrooms. The herbs should be added at the very end to preserve their vibrant color and fresh taste.
Taste the soup one final time and adjust seasoning if necessary. The finished soup should have a velvety, coating consistency that’s rich but not overly thick. If it seems too thick, thin it with additional broth or cream.
Serving Suggestions and Variations
Ladle the creamy mushroom soup into warmed bowls and garnish with additional fresh herbs or a light drizzle of cream if desired. This soup pairs beautifully with crusty bread, garlic bread, or grilled cheese sandwiches for a complete comfort meal.
For variations, you can add cooked bacon or pancetta for a smoky element, or stir in some cooked wild rice or barley to make it more substantial. A splash of truffle oil just before serving adds an elegant, luxurious touch for special occasions.
Storage and Reheating Guidelines
Store leftover creamy mushroom soup in the refrigerator for up to 4 days. The soup will thicken as it cools, so when reheating, add a splash of broth or cream to restore the proper consistency. Heat gently over medium-low heat, stirring frequently to prevent the cream from separating.
While this soup can be frozen for up to 3 months, the texture may change slightly upon thawing due to the cream content. For best results when freezing, consider leaving out the cream and adding it fresh when reheating the soup.
