Ingredients

Scale
  • 16 oz (450 g) fresh mushrooms (cremini or white button preferred)
  • 3 tbsp (45 g) unsalted butter
  • 3 garlic cloves, minced
  • 1 medium shallot, finely chopped
  • 1 tsp fresh thyme, chopped
  • 3 cups (720 ml) chicken or vegetable broth
  • 1 cup (240 ml) heavy cream
  • 4 oz (115 g) cream cheese, softened
  • 1/4 tsp ground nutmeg
  • Salt, to taste
  • Freshly ground black pepper, to taste

Instructions

  1. Clean and slice the mushrooms: Rinse mushrooms quickly under cold water and pat dry. Slice evenly about 1/4 inch thick.
  2. Heat the butter in a large skillet over medium heat until melted and slightly bubbling.
  3. Add chopped shallots and minced garlic to the pan. Cook for 2-3 minutes until softened and fragrant but not browned.
  4. Add sliced mushrooms and fresh thyme. Cook for 8-10 minutes, stirring occasionally, until mushrooms release moisture and start to brown.
  5. Transfer the mushroom mixture to a medium pot. Pour in chicken or vegetable broth and bring to a gentle simmer over medium heat. Cook uncovered for 10 minutes.
  6. Lower heat to medium-low. Stir in softened cream cheese in small dollops, stirring constantly until melted and smooth. Add heavy cream and stir to combine.
  7. Use an immersion blender in the pot to puree the soup until creamy but still with some mushroom texture. Alternatively, blend in batches in a regular blender.
  8. Season with salt, freshly ground black pepper, and a pinch of nutmeg. Stir and adjust seasoning as needed.
  9. Serve warm, garnished with extra thyme or sautéed mushroom slices. Optional: drizzle with truffle oil.

Notes

If soup is too thick after blending, stir in more broth or cream to reach desired consistency. If too thin, simmer uncovered a few more minutes to reduce. When blending hot soup, remove pot from heat and cover blender lid with a towel to prevent splatter. Use softened cream cheese to avoid lumps. Season gradually to avoid overpowering flavors.
