What You Need to Know
French Onion Soup traditionally includes bread, which is high in carbohydrates and not suitable for a ketogenic diet. The keto diet restricts carbohydrate intake to promote ketosis, where the body burns fat for fuel instead of carbs. The other ingredients, such as onions, beef broth, and Gruyère cheese, can fit into a keto diet in moderation, but the bread is a significant blocker.
