Step-by-Step Instructions

Sauté the Aromatics

Heat olive oil in a large heavy bottomed pot over medium heat until it shimmers. Add chopped onion and cook slowly for 5 minutes, stirring occasionally until they turn translucent and begin to soften. Avoid browning by adjusting heat if needed.

Brown the Mushrooms

Add minced garlic and stir constantly for 30 seconds until fragrant. Then add sliced mushrooms in a single layer without overcrowding the pot. Allow them to cook undisturbed for 3 minutes before stirring. Continue cooking for 7 more minutes until mushrooms release their moisture and develop a deep brown color and concentrated flavor.

Simmer the Base

Pour vegetable broth into the pot, using a wooden spoon to scrape up any browned bits from the bottom. These bits contain concentrated flavor. Bring mixture to a gentle simmer and maintain for 15 minutes to allow flavors to meld completely.

Finish and Blend

Reduce heat to low and stir in heavy cream and thyme. Cook for 2 minutes without boiling to prevent cream from separating. Remove from heat and carefully blend using an immersion blender until desired smoothness. Alternatively transfer in batches to a standard blender with the center cap removed and covered with a towel to allow steam escape.

Season and Serve

Return to low heat if needed to warm through. Taste and adjust seasoning with salt and pepper. Ladle into warmed bowls and garnish generously with fresh parsley just before bringing to the table.

Save

Mushrooms are truly magical ingredients in this soup. I discovered that browning them properly transforms their flavor entirely. My father who claimed to dislike mushrooms his entire life became an instant convert after tasting this soup during our holiday gathering last year.

Mushroom Selection Guide

Different mushroom varieties create entirely different flavor profiles in this soup. Button mushrooms provide a mild base, while cremini offer a slightly stronger earthy note. For an extraordinary version, try using wild mushrooms like shiitake, oyster, or chanterelle either alone or in combination. Forest mushrooms bring complex woodsy flavors that elevate this soup to restaurantquality. When shopping, always look for firm caps with no slimy spots or excessive moisture. Store mushrooms in paper bags rather than plastic to maintain freshness.

Make It Vegan

This soup transforms beautifully into a vegan version without sacrificing richness. Replace heavy cream with full fat coconut milk or cashew cream made by blending soaked raw cashews with water. The coconut version adds a subtle tropical note that pairs surprisingly well with mushrooms. For added creaminess without dairy, try stirring in a tablespoon of white miso paste which also enhances the umami qualities already present in the mushrooms. This adaptation has become so popular among my vegan friends that I often make it this way regardless of dietary restrictions.

Serving Suggestions

This mushroom soup reaches its full potential when thoughtfully paired with complementary sides. Serve with a crusty artisan sourdough bread for dipping or toasted baguette slices rubbed with garlic and drizzled with olive oil. For a complete meal, add a bright salad with vinaigrette dressing to cut through the richness of the soup. When hosting dinner parties, I serve this in small cups as an elegant starter before the main course. For special occasions, drizzle each serving with truffle oil and top with crispy fried shallots for an unforgettable presentation.

Recipe FAQs

→ What type of mushrooms work best for this soup?

While the standard recipe works wonderfully with button or cremini mushrooms, you can elevate the flavor by using a mix of wild mushrooms like shiitake, oyster, or porcini. Each variety adds different earthy notes to the final dish.

→ Can I make this soup dairy-free?

Absolutely! Substitute the heavy cream with full-fat coconut milk or a cashew cream for a dairy-free alternative that still provides richness and creaminess to the soup.

→ How long does mushroom soup keep in the refrigerator?

The soup will keep well in an airtight container in the refrigerator for 3-4 days. Reheat gently on the stovetop, adding a splash of broth if needed to adjust consistency.

→ Can I freeze this mushroom soup?

Yes, but for best results, freeze the soup before adding the cream. When ready to serve, thaw completely, heat through, and then stir in the cream. This prevents the cream from separating during freezing and reheating.

→ What herbs pair well with mushroom soup?

Thyme is classic and specified in the recipe, but rosemary, sage, and tarragon also complement mushrooms beautifully. For a fresh finish, parsley, chives, or dill make excellent garnishes.

→ What can I serve with mushroom soup?

Crusty bread or garlic toast makes an excellent accompaniment. For a more substantial meal, pair with a simple green salad dressed with vinaigrette or serve as a starter before a main course.
