Easy Cream of Mushroom Soup Recipe

This soup has a nice delicate mushroom flavor. The mushrooms are sliced, not minced, so it has a robust texture. If you like a smoother consistency, blend it in a blender or with an immersion blender on high for several minutes.

Even though the following list of ingredients may seem a little long, this is an easy mushroom soup to make.
