Golden and crunchy sourdough croutons are the essential finishing touch for a classic French onion soup.

Using day-old sourdough is the secret to achieving the perfect crouton. The slightly lower moisture content helps the bread crisp up in the oven, ensuring each bite remains crunchy rather than soggy when it meets the soup. Tossed in olive oil and garlic, these croutons become an aromatic garnish that elevates the entire meal.
