4. Step-by-Step Instructions and Directions

Step 1: Prepare the Onions
Start by peeling and thinly slicing your onions. Caramelizing the onions is the key to deep flavor in French Onion Soup, so don’t rush this process.
Pro Tip: Use a sharp knife to slice your onions evenly.

Step 2: Caramelize the Onions
In a large pot, melt the butter and olive oil over medium heat. Add the onions and a pinch of salt. Stir occasionally, letting the onions cook down slowly. This will take about 15-20 minutes. Sprinkle in the sugar to help the caramelization process.
Pro Tip: The more you let the onions caramelize, the sweeter and richer the flavor becomes.

Step 3: Add Garlic and Herbs
Once the onions are golden brown and tender, add the garlic, thyme, and bay leaf. Stir everything together and cook for an additional 1-2 minutes.

Step 4: Add the Broth and Wine
Pour in the beef broth and wine (if using). Bring everything to a boil, then reduce the heat to low. Let it simmer for 10 minutes to allow the flavors to meld together.

Step 5: Prepare the Toasted Bread
While the soup is simmering, toast the French bread slices in a toaster or under a broiler. You want them crispy, so they hold up to the broth without falling apart.

Step 6: Assemble the Soup
Ladle the soup into bowls. Top each bowl with a slice of toasted bread and a generous amount of cheese. Place the bowls under the broiler for 2-3 minutes until the cheese is melted and bubbly.
Pro Tip: If you don’t have an oven-safe bowl, you can melt the cheese in a skillet and place it on top of the soup after serving.
