Once you make your own cream of mushroom soup you will never want to go back to store bought. Best part about this recipe is that it is gluten-free too.
If you make and save for another day, this mushroom soup will thicken to a condensed soup. You can then add another 1-2 cups of milk, depending how long you heat it and how thick you want it.
