1 liter (4 cups) chicken broth – homemade or store-bought; it will serve as the soup’s foundational base.
1 liter (4 cups) beef broth – combined with chicken broth, this deepens the savory character of the soup.
15 ml (1 tablespoon) toasted flour – helps to thicken the broth slightly for a richer mouthfeel.
1 pinch of ground nutmeg – a little goes a long way in enriching the flavor.

How to Make SOUPE À L’OIGNON GRATINÉE
Follow these simple steps to prepare this delicious SOUPE À L’OIGNON GRATINÉE:
Step 1: Prepare the Onions
Start by cutting the onions into quarters, then slice each quarter into short strips. This is key for that perfect caramelization.
Step 2: Sauté the Onions
In a large, heavy pot over medium heat, melt the butter. Add the onions and cook, stirring occasionally for about 15 minutes until they are soft and translucent.
Step 3: Caramelize the Onions
Raise the heat to medium-high and continue cooking the onions, stirring constantly for another 15 minutes until they turn golden brown and beautifully caramelized. This step is crucial for developing that rich, sweet flavor.
Step 4: Deglaze with Wine and Cognac
Carefully pour in the red wine and cognac, scraping up any delicious bits stuck to the bottom of the pot. Allow it to reduce almost to dry.
Step 5: Add Broths and Seasonings
Stir in both broths along with the toasted flour and nutmeg. Mix well, and bring the mixture to a boil. Once boiling, reduce the heat and let it simmer for about 30 minutes, allowing all those wonderful flavors to meld together.
Step 6: Prepare to Serve
Preheat your oven’s broiler. Position a rack in the center and arrange 4 soup bowls on a baking sheet. Ladle soup into each bowl, topping each with about 2 tablespoons of grated Gruyère cheese and 3 slices of toasted baguette. Broil for about 5 minutes, or until the cheese is bubbling and golden brown.
Transfer to serving platters and enjoy your delicious SOUPE À L’OIGNON GRATINÉE with a sprinkle of freshly cracked pepper and a dash of love. Enjoy each warm, cheesy, and aromatic bite, and don’t be surprised if everyone comes back for seconds.
