How to Make French Onion Soup
Heat butter and olive oil in a large pot over medium heat. Add sliced onions and cook slowly, stirring occasionally, until they become soft and deeply caramelized. This process takes about 25–30 minutes and is key to rich flavor.
Add minced garlic and cook for another minute until fragrant. Pour in the broth, then add bay leaf, thyme, salt, and black pepper. Stir well and bring the soup to a gentle simmer.
Let the soup cook for 15–20 minutes so the flavors blend together. Remove the bay leaf before serving.
Toast baguette slices until crisp. Ladle soup into oven-safe bowls, place toasted bread on top, and generously sprinkle cheese over the bread. Broil until the cheese is melted and bubbly.
Serve hot and enjoy immediately.
