What You Need to Know
French Onion Soup traditionally contains beef broth, which is derived from animal sources, and Gruyère cheese, a dairy product. Both of these ingredients make the soup unsuitable for a vegan diet, as vegans avoid all animal products, including meat, dairy, and eggs.
For those following a vegan diet, it is advisable to look for alternative recipes that use vegetable broth and plant-based cheese or omit cheese altogether. Many restaurants and cookbooks now offer vegan versions of French Onion Soup that maintain the rich flavor without compromising dietary restrictions.
