Description
A traditional French onion soup with rich beef broth, caramelized onions, and a cheesy crouton topping.
Ingredients
Scale
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 4 large yellow onions, thinly sliced
- 1 teaspoon granulated sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 cloves garlic, minced
- 8 cups beef broth
- 1 cup dry white wine
- 1 bay leaf
- 4 slices baguette, toasted
- 1 cup shredded Gruyere cheese
Instructions
- Melt butter and olive oil in a large pot or Dutch oven over medium heat. Add onions, sugar, salt, and pepper. Cook, stirring occasionally, until onions are deeply caramelized, about 45-60 minutes.
- Add garlic and cook for 1 minute more until fragrant.
- Pour in white wine and scrape up any browned bits from the bottom of the pot. Let simmer for 5 minutes.
- Add beef broth and bay leaf. Bring to a simmer, then reduce heat to low, cover, and cook for at least 30 minutes. Remove bay leaf.
- Preheat broiler. Ladle soup into oven-safe bowls. Top each bowl with a slice of toasted baguette and a generous amount of Gruyere cheese.
- Broil for 2-3 minutes, or until cheese is melted and bubbly. Serve immediately.
Notes
- For an even richer flavor, you can use a combination of beef and chicken broth.
- If you don’t have Gruyere cheese, Swiss or provolone cheese can be substituted.
