What You Need to Know
French Onion Soup traditionally contains Gruyère cheese, which is a dairy product high in lactose. This makes the dish unsuitable for those who are lactose intolerant or following a lactose-free diet.
For individuals avoiding lactose, consider making a modified version of French Onion Soup. Substitute Gruyère cheese with lactose-free cheese or nutritional yeast for a cheesy flavor without the lactose. Always check the ingredients in the broth and bread to ensure they are also lactose-free.
