Chef John's Creamy Mushroom Soup

Chef John's Creamy Mushroom Soup

This mushroom soup is creamy and rich. A long, slow caramelization of the mushrooms requires patience, but unlocks their magical flavor, which is the secret to this soup.

Recipe Instructions

Step 1
Add onion to the mushrooms; cook until onion is soft and translucent, about 5 minutes.
Step 2
Stir flour into the mushroom mixture and cook, stirring often, to remove the raw flour taste, about 2 minutes.
Step 3
Add thyme bundle and garlic cloves, then pour in 4 cups chicken broth and 1 cup water. Reduce heat to low and simmer for 1 hour. Remove and discard thyme bundle.
Step 4
Ladle into bowls, and garnish with reserved mushroom slices and thyme leaves.
Step 5
Gather all ingredients.
Step 6
Melt butter in a large soup pot over medium-high heat. Sauté mushrooms and 1 pinch salt in the melted butter until mushrooms release their juices, 5 to 10 minutes. Reduce heat to medium-low and continue to cook, stirring often, until juices evaporate and mushrooms are caramelized, 15 to 25 minutes. Set aside a few attractive mushroom slices for garnish later, if desired.
Step 7
Purée soup with a blender in batches until smooth and thick.
Step 8
Stir in cream. If too thick, add a little chicken broth or water. Season with salt and black pepper.
