Ingredients
For the Soup:
- 4 large yellow onions, thinly sliced – The star of the show, caramelized to perfection.
- 3 tablespoons unsalted butter – For richness and flavor.
- 1 tablespoon olive oil – Helps prevent the butter from burning.
- 1 teaspoon sugar – Aids in the caramelization of the onions.
- 2 cloves garlic, minced – Adds depth to the flavor.
- 1/2 cup dry white wine (optional) – Enhances the richness and complexity of the soup.
- 6 cups beef broth (or vegetable broth for a vegetarian option) – Forms the savory base.
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme) – Adds a subtle herbal note.
- 1 bay leaf – Infuses the soup with a delicate aroma.
- Salt and freshly ground black pepper, to taste – Essential for seasoning.
For the Topping:
- 6 slices of French baguette, toasted – Serves as the perfect base for the melted cheese.
- 1 1/2 cups grated Gruyère cheese – For that irresistible golden, bubbly topping.
How to Make French Onion Soup
Caramelize the Onions:
- Heat the butter and olive oil in a large, heavy-bottomed pot over medium heat.
- Add the sliced onions and sugar, stirring to coat them in the butter.
- Cook for 25–30 minutes, stirring frequently, until the onions are deeply golden and caramelized. Lower the heat if they start to brown too quickly.
Add the Garlic and Deglaze:
- Stir in the minced garlic and cook for 1 minute until fragrant.
- Pour in the white wine, if using, and scrape up any browned bits from the bottom of the pot. Simmer until the wine has reduced by half, about 2–3 minutes.
Build the Broth:
- Add the beef broth, thyme, and bay leaf to the pot. Stir well and bring the mixture to a gentle simmer.
- Cover and let the soup simmer for 20–25 minutes to allow the flavors to meld. Remove the bay leaf before serving.
Prepare the Toasts:
- While the soup is simmering, preheat your oven to broil.
- Place the baguette slices on a baking sheet and toast them under the broiler for 1–2 minutes on each side until golden brown.
Assemble and Broil:
- Preheat oven-safe soup bowls by placing them on a baking sheet. Ladle the soup into the bowls.
- Place a slice of toasted baguette on top of each bowl of soup, then generously sprinkle the grated Gruyère cheese over the bread.
- Place the bowls under the broiler for 2–3 minutes, or until the cheese is melted, bubbly, and golden brown.
Serve and Enjoy:
- Carefully remove the bowls from the oven and serve immediately. Garnish with a sprig of fresh thyme for a final elegant touch.
