Let’s dive into the steps to create this timeless favorite.
Ingredients
Here’s what you’ll need for 4 servings of this indulgent soup:
For the Soup Base
4 large yellow onions, thinly sliced
2 tbsp unsalted butter
2 tbsp olive oil
1 tsp sugar (to enhance caramelization)
1 tsp salt
4 cloves garlic, minced
8 cups beef broth
1/2 cup dry white wine (optional for deglazing)
2 bay leaves
1 tsp dried thyme
Salt and pepper, to taste
For the Topping
1 baguette, sliced
2 cups grated Gruyère cheese
Step-by-Step Directions
1. Caramelize the Onions
In a large pot, melt butter with olive oil over medium heat. Add the sliced onions, sugar, and salt.
Cook for 30-40 minutes, stirring occasionally, until the onions are caramelized, soft, and golden brown. Be patient—this step develops the soup’s rich flavor.
2. Add Garlic and Deglaze the Pot
Stir in the minced garlic and cook for an additional 2 minutes until fragrant.
Pour in the dry white wine to deglaze the pot, scraping up any flavorful browned bits from the bottom. Let it simmer for 2-3 minutes to reduce slightly.
3. Build the Broth
Add the beef broth, bay leaves, and thyme to the pot.
Bring the soup to a gentle boil, then reduce the heat and simmer uncovered for 30 minutes, allowing the flavors to meld. Season with salt and pepper to taste.
4. Prepare the Baguette Slices
Preheat your oven to 400°F (200°C).
Arrange the baguette slices on a baking sheet and toast for 5-7 minutes, or until golden brown.
5. Assemble and Broil
Remove the bay leaves from the soup and ladle it into oven-safe bowls.
Place a toasted baguette slice on top of each bowl and generously sprinkle with grated Gruyère cheese.
Place the bowls under the broiler for 3-5 minutes, or until the cheese is melted, bubbly, and golden brown.
6. Serve Hot
Carefully remove the bowls from the broiler and serve the soup immediately. Pair it with a side salad or extra baguette slices for dipping.
Cooking Tips for Success
Onions
Use yellow onions for their natural sweetness, which caramelizes beautifully.
Slice the onions evenly to ensure they cook uniformly.
Broth
Beef broth provides a robust flavor, but you can use chicken or vegetable broth for a lighter option.
Cheese Alternatives
While Gruyère is traditional for French Onion Soup, you can substitute with Swiss, Comté, or Mozzarella for a similar melty, gooey effect.
Wine Substitution
If you prefer not to use wine, deglaze the pot with an equal amount of apple cider vinegar, lemon juice, or additional broth.
