To make this 5 ingredients Souper Rice gluten free, use a certified gluten-free cream of chicken soup, as many canned condensed soups contain wheat as a thickener. Also check that the chicken broth, chicken bouillon, Italian seasoning, and Parmesan cheese are labeled gluten free and free from cross-contact warnings. The instant white rice is often naturally gluten free, but it is still worth checking the packaging to confirm. Once those ingredient swaps are made, the rest of the recipe can remain the same.
