What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 600 g mixed mushrooms roughly chopped
  • 1 large onion diced
  • 3 cups vegetable broth
  • 1 cup heavy cream
  • 2 tbsp olive oil
  • 1 tsp dried rosemary

Step by step instructions

Step 1: Saute Onion and Mushrooms

Heat olive oil in a large pot over medium heat and cook the diced onion for 5 minutes until softened. Add chopped mushrooms and cook for another 8 minutes until they release their liquid and begin to brown.

Step 2: Add Broth and Simmer

Pour in the vegetable broth and dried rosemary, then bring the mixture to a gentle boil. Reduce heat and simmer for 15 minutes to develop a deep flavor.

Step 3: Blend Until Smooth

Use an immersion blender directly in the pot or carefully transfer the soup in batches to a blender. Blend until completely smooth and silky.

Step 4: Stir in Cream and Serve

Return the blended soup to low heat and stir in the heavy cream. Heat gently for 2 minutes, adjust seasoning, and serve with crusty bread.
