Ingredients List
For making Classic French Onion Soup, gather the following ingredients:
- 4 large yellow onions (about 2 pounds)
- 6 cups beef stock
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- Salt and pepper to taste
- 1 cup dry white wine (optional)
- 8 slices of French bread
- 1 ½ cups gruyère cheese (shredded)
Directions
- Sauté the Onions: In a large Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook for 20-30 minutes, stirring occasionally, until the onions are golden brown and caramelized.
- Deglaze the Pot: Pour in the dry white wine (if using) and use the wooden spoon to scrape any browned bits from the bottom of the pot. Allow the wine to reduce for about 3-5 minutes.
- Simmer the Broth: Add the beef stock to the pot, along with salt and pepper to taste. Bring the mixture to a gentle simmer and let it cook for another 15-20 minutes to allow the flavors to meld.
- Prepare the Bread: While the soup is simmering, preheat your broiler. Toast the slices of French bread until they are crispy and golden on both sides. Set aside.
- Assemble and Broil: Ladle the hot soup into broiler-safe bowls. Place a slice of toasted bread on top of each bowl and generously sprinkle with gruyère cheese. Place the bowls under the broiler for 2-3 minutes, or until the cheese is bubbly and melted.
Pro Tips for Success
- Choosing the right onions: Yellow onions are recommended for their sweetness when caramelized.
- Achieving perfect caramelization: Be patient and keep the heat consistent to avoid burning the onions.
- Broiling tips: Watch closely while broiling to prevent burning the cheese.
