A rich creamy soup; can be made up to 3 days ahead.
- 4 tablespoons unsalted butter
- 2 leeks, white and light green parts only, halved lengthwise and thinly sliced
- 1 large onion, chopped

- 6 cups low sodium chicken broth
- 1 teaspoon salt
- 1 teaspoon sugar
- 1⁄2 teaspoon pepper
- 1 cup heavy cream
- 1⁄4 cup chopped fresh parsley
- Saute the leeks and onions in butter in a large pot over medium heat, stirring constantly, until tender; about 2-3 minutes.
- Lower heat, add the mushrooms, and cook about 10 minutes longer, covered, stirring occasionally.
- Raise heat to medium, stir in the flour, and cook for 2-3 minutes, then add the thyme, bay leaf, broth, salt, sugar, and pepper.
- Simmer, partially covered, for about 10 minutes.
- Cool the soup slightly; discard the bay leaf; then puree the soup in batches in a blender or food processor.

- Cook over low heat until just heated through, but do not boil.
- Adjust seasonings if necessary, and serve garnished with parsley.
Thanks sooooo much for posting this! It was wonderful!! I must confess that I didn't follow your recipe exactly, partly due to my market and partly personal preference. The portobellos were awful, so I was forced to buy the "baby bellas" (1 lb) and used them instead, I also added some white mushrooms (button?) because I had them on hand, a pinch of nutmeg and a splash of chardonnay. (I seem to add wine to everything these days LOL.) For dietary reasons, I substituted fat free half & half for the heavy cream. This was by all means the BEST mushroom soup I've ever had, bar none...better than my own recipe (which I thought was wonderful) that I've used for years! I will definitely add this to my "regulars" :)
Very, very good Mushroom Soup! I used 4 portbello mushrooms and 1/2 & 1/2 cream, plus celery leaves chopped up as garnish. At first, I did not puree the soup and it tasted good. Then decided to puree it and the soup was better. Next time I will add some white buttom mushrooms at the end and cut up into big slices (not pureed).
This soup was very tasty and will go into the cookbook to have again. I used white mushrooms and added a few shitakes. The thyme seasoning was just right but I did add some garlic. Very creamy. Easy to put together and was quickly on the table. I served with slices of French bread toasted. Thank you for posting. Catherine
