What You Need to Know
French Onion Soup traditionally contains bread, which is made from wheat and contains gluten. Gluten is a protein found in wheat, barley, and rye, making this classic soup incompatible with gluten-free diets. The bread is often used as a topping, creating a crusty layer that is integral to the dish's texture and flavor, further solidifying its non-gluten-free status.
For those adhering to a gluten-free diet, it is essential to seek alternatives that do not include gluten-containing ingredients. Consider using gluten-free bread or omitting the bread altogether to enjoy a modified version of this savory soup. Always check labels for hidden gluten in broths and cheese, and consult with a healthcare provider for personalized dietary advice.
