To make this Crack Chicken Noodle Soup gluten free, replace the flour with a gluten-free all-purpose flour blend or cornstarch slurry, and use gluten-free pasta in place of the egg noodles. You should also confirm that the ranch seasoning mix, chicken broth, cream cheese, and bacon are labeled gluten free, since ingredients and additives can vary by brand. If using rotisserie chicken, check that no gluten-containing seasonings or fillers were used during preparation. Once those substitutions are made, this soup can be adapted quite easily for a gluten-free version.
