For an even more intense flavor, consider adding roasted garlic to the soup. Simply roast a head of garlic alongside the onions during the caramelization process. The type of bread you use will affect the final texture of the soup. Stale bread works best, as it will break down more easily and thicken the soup effectively. French or Italian bread are both excellent choices. Don't be afraid to experiment with different types of white wine. A crisp Sauvignon Blanc or a dry Pinot Grigio would both be delicious in this soup.

Follow The Directions
01
StepIn a large, heavy-bottomed pot, heat the olive oil over medium heat. Add the sliced onions and toss to coat evenly with the oil. Cover the pot, reduce the heat to medium-low, and cook, stirring occasionally, until the onions have softened and are beginning to take on some color (about 30 minutes).
02
StepIncrease the heat to medium and continue cooking, stirring occasionally and uncovered, until the onions achieve a beautiful amber color (about 45 minutes).
03
StepSprinkle the sugar and a pinch of salt over the onions. Cook, stirring constantly, until the sugar melts completely and the onions are richly caramelized (about 5 minutes).
04
StepPour in the white wine and chicken broth, then add the cinnamon stick to the pot. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 1 hour to allow the flavors to meld together beautifully.
05
StepStir the cubed bread into the soup and cook, uncovered, stirring occasionally, until the bread has largely disintegrated, thickening the soup (about 30-45 minutes).
06
StepRemove the cinnamon stick. Use a whisk to further incorporate the bread into the soup, creating a smooth and creamy consistency. Adjust the seasoning to your liking. Serve hot and enjoy!
