What You Need to Know
French Onion Soup traditionally contains bread, which is made from wheat and therefore contains gluten. Gluten is a protein found in wheat, barley, and rye, making this classic dish unsuitable for those with gluten intolerance or celiac disease. Even though the other ingredients like onions, beef broth, and Gruyère cheese are gluten free, the inclusion of bread renders the entire dish incompatible with a gluten free diet.
