Homemade gluten-free cream soups aren't hard to make, and gluten-free sweet rice flour is an excellent thickener. Gluten-free cream of mushroom soup with a creamy fresh flavor takes less than 20 minutes to make. It's simply prepared with mushrooms, onions, garlic, and cream, uses gluten-free flour and chicken broth, then topped with fresh basil.

Gluten-free cream of mushroom soup is a versatile recipe because you can use it to make classic dishes like gluten-free tuna casserole and other casserole dishes.

If eating as a soup, enjoy it with a tossed salad for a complete meal.

"This gluten-free soup comes together very quickly and is a good canvas for other flavors and ingredients. The sweet rice flour works just as well as wheat flour in thickening the soup. The soup is smooth and not grainy at all." —Young Sun Huh

How to Store and Freeze

  • If you have leftovers and are planning on using them within three days, just put your soup in the refrigerator in an airtight container. Remember to do this within two hours, even if it is still slightly warm.
  • Freeze your soup by putting it into an airtight plastic container or freezer bag. Plan to use it within three months. 

Recipe Variations

  • Add a good amount of paprika with the mushrooms and garnish with a dollop of sour cream and parsley for a Hungarian-style mushroom soup.
  • Almost any herb, such as thyme, parsley, dill, and chives, would work well with this soup,
  • Spike the soup with a little sherry or cognac for a sophisticated addition.
