Panera's Bistro French Onion soup is a sophisticated and savory option for those who love deep, caramelized flavors. We slow-cook sweet onions until they are rich and dark, then simmer them in a robust beef broth accented with sherry wine vinegar and sea salt. Each bowl is served with a topping of crispy, fontina-mozzarella cheese croutons.
The result is a classic bistro-style soup that is both aromatic and deeply satisfying, with a perfect balance of sweet and salty notes.
