My family used to eat the popular canned version of cream of mushroom soup often. As an adult, I still love the simple soup, but it’s much more appetizing when made from scratch. The soup is creamy, and the tarragon really accentuates the earthiness of the fresh mushrooms. I love that it’s effortless to make in the slow cooker, so I don’t have to trade convenience for all that extra flavor.
Cream of mushroom soup is a hearty, rustic dish, so we served it with a loaf of pumpernickel bread. It doesn’t get more satisfying than this when it comes to late winter comfort food.
If you can’t find tarragon, you can substitute thyme, and if you want to add extra depth, you can replace the vegetable broth with chicken broth. Add in some wild mushrooms (such as shiitake or portobello) and blend the soup more or less depending on how you like it. There are many ways to make this cream of mushroom soup recipe your own.
