Gluten Free Cream of Mushroom Soup is a homemade version of the condensed can of soup you see in every casserole recipe. It's super easy to make, and you can make a big batch and freeze it for when you need a quick ingredient for a recipe. You can also add some water and have it as just a bowl of soup!
In a medium saucepan sauté onion and mushrooms in butter over medium heat until browned. Stir in spices and broth.
Separately, whisk together half & half and gluten free flour. Pour into the soup and stir. Once soup begins to thicken, remove from heat.
