Can’t decide between a potato or mushroom side dish? Have them both! The sauce comes together easily with cream and vegetable broth, while rosemary adds just the right amount of subtle flavor. And you can’t forget the crunchy bread crumb and Parmesan topping!

Tips from the Betty Crocker Kitchens

  • tip 1
    We used white button mushrooms for this recipe, but if you like a more pronounced mushroom flavor, you can try sliced cremini mushrooms.
  • tip 2
    Gruyère cheese would make a delicious substitute for Swiss cheese in this recipe.
