French Onion Soup is a true classic, transforming simple ingredients like onions and broth into an unforgettable culinary experience. Its secret lies in the slow, careful caramelization, which imparts a deep, sweet flavor to the onions. The crispy, cheesy bread crown on top completes this warming, rich soup, making it a perfect choice for cold days or as an elegant appetizer.

Steps

Prepare Onions

Peel and thinly slice the onions. In a large, heavy-bottomed pot, melt the butter with the olive oil over medium heat.

Caramelize Onions

Add the sliced onions to the pot and sprinkle with a pinch of salt. Cook, stirring frequently, over low to medium heat for about 40-60 minutes, until the onions are deeply golden brown and sweet. This step is crucial, do not rush it!

Deglaze and Simmer

Pour in the white wine and scrape up any caramelized bits from the bottom of the pot. Let the wine evaporate (about 2-3 minutes). Then, add the beef broth, thyme, and bay leaf. Bring to a boil, then reduce heat and simmer for 20-30 minutes to allow the flavors to meld. Season with salt and freshly ground black pepper to taste.

Serve and Gratinate

Preheat your oven broiler. Toast the baguette slices in a pan or toaster. Ladle the hot soup into oven-safe bowls. Place one toasted baguette slice on top of each bowl, then generously sprinkle with grated cheese. Place the bowls under the hot broiler for 3-5 minutes, until the cheese is melted and golden brown. Carefully remove and serve immediately.

Extra Tips

► Be patient with caramelizing the onions; this step gives the soup its depth and sweetness.

► If you don't have white wine, a little brandy or cognac can be used for deglazing.

► You can prepare the soup in advance and reheat it before serving, then add the cheesy bread.
