Build a bowl of French Onion Soup includes which components?

• A. Cream of tomato soup with croutons
• B. Soup Base, crostini(s), Swiss cheese, provolone, seasoned bread crumbs
• C. Tomato soup with basil
• D. Mushroom soup with onions

Answer: (B)

French Onion Soup is built from a rich onion-based broth as the base, then topped with toasted bread and melted cheese. The bread (crostini or croutons) provides the crispy, saucy foundation that soaks up the flavorful onion liquid, while the cheese melts over the top to create a gooey, browned topping. The combination of a flavorful soup base, toasted bread, and two cheeses that melt well is exactly what the listed components describe: a soup base, crostini, Swiss cheese, provolone, and seasoned breadcrumbs for texture and finishing flavor. Other descriptions mention tomato or mushroom soups or different bases, which don’t capture the classic onion-forward composition and topping style of this dish.
