This recipe for Homemade Condensed Cream of Mushroom Soup replaces a can of canned soup from the store, or add 2 cups water to the recipe below for 4 cups of creamy mushroom soup.
In a large saucepan over medium-high heat, melt butter until foaming. Add mushrooms and cook until they have released most of their liquid, about 5 to 7 minutes.
Stir in chicken broth, onion powder, and garlic powder and bring to a simmer. In a small bowl, whisk together milk and flour.
Stir in milk mixture and cook until soup has thickened, about 1 minute. Season to taste with salt and pepper.
For un-condensed soup: Add 2 cups water to make 2 servings of soup, 2 cups each (stir over medium heat until heated through).
