Learn how to make delicious French Onion Soup. Easy recipe with step-by-step instructions.
Total Time:45 minutes
Yield:4 servings
Ingredients
6 large yellow onions, thinly sliced
4 tablespoons unsalted butter
2 tablespoons olive oil
1 teaspoon salt
1/2 teaspoon sugar
1 tablespoon all-purpose flour
8 cups beef broth (or vegetable broth for a vegetarian option)
1/2 cup dry white wine
2 tablespoons brandy (optional)
1 bouquet garni (a bundle of thyme, bay leaf, and parsley)
Salt and pepper to taste
1 baguette, sliced
2 cups grated Gruyère cheese
Instructions
In a large, heavy-bottomed pot, melt the butter with olive oil over medium heat. Add sliced onions, salt, and sugar. Stir well to coat the onions.
Reduce the heat to medium-low, and cook the onions, stirring occasionally, until they are deeply caramelized. This should take about 45 minutes. Patience is key here — let the onions do their magic.
Sprinkle the flour over the onions and cook for another 2 minutes, stirring constantly. This step helps thicken the soup slightly.
Pour in the beef broth and white wine, scraping up any brown bits from the bottom of the pot. Add the brandy and bouquet garni. Bring to a simmer and let it cook for another 30 minutes.
While the soup simmers, preheat your oven to 400°F. Lay the baguette slices on a baking sheet and toast them for about 10 minutes or until golden.
Remove the bouquet garni from the soup and season with salt and pepper to taste.
To serve, ladle the soup into oven-safe bowls. Top each with a slice of toasted baguette and a generous handful of Gruyère cheese.
Place the bowls on a baking sheet and broil in the oven until the cheese is bubbly and golden, about 5 minutes. Serve hot and enjoy!
