Variations & Tips
For a richer flavor, you can add a splash of Worcestershire sauce or a teaspoon of Dijon mustard to the sauce. If you have picky eaters, you can substitute the cream of mushroom soup with cream of chicken soup. For a lighter version, use Greek yogurt instead of sour cream. Feel free to add some sautéed mushrooms or onions for extra flavor and texture.
