French Onion Soup with Gruyère Cheese

Ingredients

• 4 large yellow onions thinly sliced
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 4 cups beef broth low sodium
• 2 cups chicken broth low sodium
• 1/2 cup dry white wine
• 1 teaspoon sugar
• 1 teaspoon salt
• 1/4 teaspoon black pepper freshly ground
• 1 teaspoon fresh thyme leaves
• 4 slices baguette toasted
• 2 cups Gruyère cheese grated

Instructions

1. 1 In a large pot, melt butter with olive oil over medium heat.
2. 2 Add the sliced onions and cook, stirring occasionally, until they are caramelized, about 25-30 minutes.
3. 3 Sprinkle sugar and salt over the onions, continue to cook for another 5 minutes to deepen the caramelization.
4. 4 Add the white wine to the pot, scraping up any browned bits from the bottom of the pot, and simmer until the wine is mostly evaporated.
5. 5 Stir in the beef broth, chicken broth, thyme, and black pepper. Bring to a boil, then reduce heat and simmer for 20 minutes.
6. 6 Preheat the oven broiler. Ladle the soup into oven-safe bowls and place on a baking sheet.
7. 7 Place a toasted baguette slice on top of each bowl of soup and sprinkle generously with grated Gruyère cheese.
8. 8 Broil the soup in the oven until the cheese is bubbly and golden brown, about 3-5 minutes. Serve hot.
