Detailed Directions and Instructions
Chopping Mushrooms
Cut the white and brown mushrooms into 4 slices, then dice them into 3 or 4 pieces.
Saute Onion and Garlic
Melt 30g (2 tbsp) of unsalted butter in a large pot over medium-high heat. Add the chopped onion and minced garlic to the pot. Cook for 3 minutes until the onion and garlic are softened but not golden.
Cook Mushrooms
Add the chopped white and brown mushrooms to the pot. Cook for 10 minutes, stirring regularly. Do not attempt to brown the mushrooms; they will not brown as the pot is too crowded, but this is not necessary.
Simmer
After the mushrooms have cooked, add 3 1/4 cups of vegetable stock, 1/4 tsp of salt, and 1/8 tsp of black pepper to the pot. Bring the mixture to a boil, then reduce the heat to medium and let it simmer gently for 15 minutes without a lid.
Add Cream
Stir in 3/4 cup of crème fraiche or full-fat cream. Allow the mixture to simmer for an additional 5 minutes.
Blitz the Soup
Transfer the soup to a blender (may need to do in batches). Remove the cap from the feeding hole in the blender lid and cover the hole with a folded tea towel. Blend until the soup is completely smooth.
Return to Pot
Pour the blended soup back into the pot. Simmer for a minute or two until the bubbles caused by blending largely subside, and ensure the soup is hot.
Serve
Ladle the soup into bowls. Garnish with a drizzle of extra virgin olive oil or cream, croutons, and roughly chopped parsley or chervil if desired. Provide bread for dunking.
Notes
Mushrooms
A combination of white and brown mushrooms is recommended for balancing flavor and color. Swiss Brown/Cremini mushrooms provide a more robust flavor but will darken the soup. You can use all white mushrooms for a lighter soup that remains fabulously flavorful.
Stock
Utilizing high-quality stock significantly enhances the flavor of the soup. Homemade vegetable stock is encouraged for best results. Chicken stock is also an excellent option for those who want to incorporate meat.
Crème Fraiche
Crème fraiche is thicker than regular pouring cream and has a mild tangy flavor, adding a subtle freshness to the soup. If unavailable, regular pouring cream can be used as a substitute.
Croutons
To prepare croutons, cut any crustless bread into 0.75 cm (1/3 inch) cubes. Toss the cubes in olive oil and sprinkle with a pinch of salt. Bake at 180°C (350°F) for 10 minutes, tossing halfway, until they are golden and crunchy. Allow to cool completely on the tray before using.
Blending
To avoid a soup explosion, allow heat to escape while blending. Cover the feeding hole in the blender with a tea towel. If blended with a tightly sealed lid, the hot steam can cause the lid to blow off, resulting in a messy kitchen.
Storage
The soup will keep in the refrigerator for 4 to 5 days or can be frozen for up to 3 months.
Nutrition
Nutritional information does not account for toppings, as the amount of croutons and butter used can vary significantly.
