                                While often perceived as a simple broth and onion dish, an average serving of French onion soup can contain between 13 and 26 grams of protein, according to multiple nutrition databases. This substantial amount of protein comes from key components like the cheese topping and a rich beef broth, making it a surprisingly hearty and filling meal.
