What You Need to Know
French Onion Soup typically contains Gruyère cheese, which is a dairy product and therefore not suitable for those who are lactose intolerant. The presence of cheese makes this classic dish incompatible with a lactose-free diet, as it introduces lactose that can cause digestive discomfort for sensitive individuals.
For those adhering to a lactose-free diet, it is advisable to avoid traditional French Onion Soup or seek out variations that substitute the cheese with lactose-free alternatives. Additionally, using dairy-free cheese or omitting the cheese altogether can help create a version that is more suitable for lactose-intolerant individuals while still enjoying the rich flavors of the soup.
