Uncle Bill's French Mushroom Soup

READY IN: 42mins
Recipe by William Uncle Bill

The original recipe appeared on Mushrooms Canada website. I made some changes to enhance the soup. This is easy to make and has a very pleasant mushroom flavor.

Very good soup. I used Swiss Brown Mushrooms as it's the only thing I have (roughly chopped), scaled the recipe down to 4servings and followed everything else. The one and only changes that I made was I added 1/2 teaspoon of garlic powder in it. Thank you very much, Uncle Bill! :-)

Ingredients Nutrition


  1. Rinse both mushrooms in cold water and immediately pat dry with paper towels.
  2. Cut mushrooms into quarters and then slice thinly, 1/8 inch thick.
  3. In a large heavy bottom soup pot, melt butter on medium heat.
  4. Add mushrooms and saute for 5 to 6 minutes or until liquid from the mushrooms has mostly evaporated.
  5. Sprinkle flour over mushrooms and cook for 1 minute, stirring often.
  6. Gradually stir in chicken broth, water and chicken soup base and bring to boil, about 5 minutes, stirring often so the bottom does not burn.
  7. Add thyme, bay leaf and green onions.
  8. Reduce heat, cover and simmer for 20 minutes.
  9. Remove bay leaf and discard.
  10. In a mixing bowl, whisk together egg yolks and whipping cream.
  11. Slowly add 1 cup of hot broth mixture from the soup pot to the egg/cream mixture, whisking constantly until incorporated. This prevents the egg yolks from cooking.
  12. Return mixture to the soup pot, adding slowly and whisking all the time while adding.
  13. Heat over low heat until hot, about 5 minutes.
  14. Add white pepper to taste.
  15. Serve soup sprinkled with minced parsley.
