Julia Child’s Cream of Mushroom Soup

Julia Child's cream mushroom soup

My first taste of cream of mushroom soup was at Pizza Hut when I was 15. From that point on, it’s been one of my favorite soups. Since then, I’ve tried many versions of mushroom soup and enjoyed them all. Today, I decided to try the classic cream of mushroom soup from Julia Child’s Mastering the Art of French Cooking. The original recipe is really long and it took me some time to figure out all the steps. In the end, I was surprised that the cooking process was actually quite simple.

There are tons of online recipes based on Julia Child’s cream of mushroom soup. However, I decided to sum up the recipe with step-by-step photos so you can easily see the cooking process in a straightforward way.

The soup came out nicely. It is not like those thick soups you might find in a chain restaurant or from a can. You can taste the delicious chicken soup infused with tons of mushroom flavor. The seasonings are simple and bring out the fragrance of the ingredients without overpowering any element. The soup has a creamy texture but is not heavy. This recipe supposedly generates 4 to 6 servings, but I can finish an entire batch in one sitting.

  5. While simmering the broth, cook the mushroom caps. Melt the remaining 2 tablespoons of butter in a dutch oven or heavy bottom pot until butter starts to bubble. Add mushroom slices and season with salt and lemon juice. Stir a few times to mix well. Simmer, covered and over low heat, for 5 minutes.
  6. When the broth is done, place a colander over the pot with the sauteed mushrooms. Pour broth through the colander into that pot.

    As someone who has cooked this recipe by the book multiple times, and was only looking for the egg yolk to cream ratio, this recipe is exactly the Julia Child method distilled to normal english.

      Thanks for your kind words Ryan! I adapt this recipe long time ago, but I remember I added a bit more cream than the cookbook, otherwise the soup won’t be very creamy. Hopefully the recipe is helpful 🙂

        This is a very nice recipe and very close to the original. I used a tray of mixed varieties of mushrooms (Lidl sells them in Europe) which worked well though I think I would increase the proportion of mushrooms overall, but maybe not if those you use are strongly flavoured.

        I dug out Julia’s book while making this and I notice you doubled the amount of egg/cream mix. To be on the safe side I started off using half what you suggest and decided I wouldn’t want to add any more. It may depend on the type of cream and quality of eggs, it’s easy enough to start with two and decide whether to add more.

        It needs to be served at once as it’s pretty delicate once the eggs go in, but I’ve got some left over so I’ll try to reheat it gently in a bain marie.
        BTW, I think you forgot to mention adding the thyme along with the stock.

        Hi Paul, thanks for your feedback! I doubled the cream because I found my soup was super thin. You’re right. It’s probably because the egg I used was very tiny, and the creamy wasn’t very rich.
        It’s a great idea to add multiple mushrooms into the soup. I have some dried wild mushrooms at home, so I’d love to try out a mixture of different types.
        Oops, I totally forgot about the thyme. Just updated the recipe. Thanks for taking time to share your cooking experience Paul! Talking about this soup makes me so hungry now! I haven’t cooked this soup for a long time and you just reminded me how good it is. Can’t wait to cook it again, with mixed varieties of mushrooms of course 🙂

        As a footnote, gentle warming over a larger pan of boiling water worked perfectly as a way of reheating it several hours after making it. I took care to stir it gently so the edges didn’t boil.

        This is great to know Paul! I never got to heat them up because I always finish a big pot myself. Next time I need to make a big batch. Great ti know the tip so I can heat it up properly 🙂
