Ingredients

Scale

Soup Base

  • 2 tablespoons butter
  • 1 small onion, diced
  • 1 tablespoon olive oil
  • 1 lb mushrooms (cremini, button, or portobello), sliced
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves or ½ teaspoon dried thyme

Broth and Thickening

  • 4 cups vegetable or chicken broth
  • 1 tablespoon all-purpose flour (optional, for thickening)

Finishing Touches

  • 1 cup heavy cream or half-and-half (for lighter version)
  • Salt and pepper to taste
  • Fresh parsley, chopped (for garnish)
  • Optional: a splash of white wine or sherry

Instructions

  1. Sauté the Aromatics: In a large pot, melt the butter with the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened and translucent. Then add the minced garlic and thyme, cooking for another 1-2 minutes until fragrant.
  2. Cook the Mushrooms: Add the sliced mushrooms to the pot and cook, stirring occasionally, for 8-10 minutes until they release their moisture and become soft and browned. Optionally, deglaze the pot with a splash of white wine or sherry, scraping up any browned bits for extra flavor.
  3. Thicken the Soup (Optional): Sprinkle the flour over the mushrooms and stir well to combine. Cook for 1-2 minutes to eliminate the raw flour taste, helping to thicken the broth as it simmers.
  4. Add the Broth and Simmer: Pour in the vegetable or chicken broth and bring to a simmer. Let cook for 10-15 minutes to develop flavors and slightly reduce the soup.
  5. Blend the Soup: Use an immersion blender directly in the pot to blend until creamy, leaving some chunks if desired. Alternatively, blend in batches using a regular blender and return soup to the pot.
  6. Add the Cream: Stir in the heavy cream or half-and-half and cook for 3-5 minutes until heated through. Taste and adjust seasoning with salt and pepper.
  7. Serve: Ladle the soup into bowls and garnish with fresh parsley. Optionally serve with crusty bread or grated Parmesan.

Notes

  • For extra umami, add a splash of soy sauce or a pinch of miso paste.
  • To lighten the soup, substitute heavy cream with whole milk or use coconut milk for a dairy-free alternative.
  • This soup can be made ahead and refrigerated for 3-4 days or frozen for up to 3 months. Cool completely before storing.
