Sadly, regular cream of chicken soup is NOT gluten-free. And you may want to watch which hash browns you use too, because some have a coating that makes them not gluten-free, as well. BUT there is hope for all of us gluten-free peeps. There are gluten-free hash browns; just read the labels on the packaging before purchasing. AND there are options for gluten-free cream of chicken soup, as well. So you can make this a gluten-free hash brown casserole if needed.
