Directions
-
Melt the butter and olive oil together in a heavy, 4-quart soup pot over low heat.
-
Add the sliced onions, cover, and cook for 15 to 20 minutes, stirring occasionally.
-
Raise the heat to moderate, uncover the pot, and add the sugar and salt.
-
Cook for 20 to 30 minutes longer, stirring frequently, until the onions turn a rich mahogany brown.
-
Reduce heat to low, add the garlic, and cook for 1 minute.
-
Stir in the flour and cook, stirring constantly, for 2 to 3 minutes to form a roux.
-
Remove the pan from heat and blend in 1 cup of hot stock until the flour is completely dissolved.
-
Stir in the remaining stock, wine, vinegar, thyme, and pepper, then bring to a boil.
-
Lower heat and simmer slowly with the lid slightly ajar for 30 minutes.
-
Add the bay leaf for the last 15 minutes of simmering, then discard it before serving.
-
Taste the soup and adjust seasonings with salt and pepper as needed.
-
Preheat the broiler and smear a bit of butter in the bottom of individual heatproof bowls.
-
Place a crouton on the bottom of each bowl and sprinkle generously with Gruyère cheese.
-
Ladle the hot soup over the bread and cheese, filling the bowls.
-
Float another crouton on top of each serving and sprinkle with more Gruyère and Parmesan.
-
Drizzle with a bit of melted butter and place under the broiler for a few minutes.
-
Watch carefully until the cheese is crusty and bubbling, then serve immediately.

Note
The soup can be prepared several days in advance; in fact, the flavor improves with age. If making ahead, store the soup base in the refrigerator and assemble with bread and cheese just before serving to keep the crust crisp.
If you are planning to serve gratin-style, have your guests ready as you remove the bowls from the broiler, or the crust will sink like a leaky barge.
For a variation, try bruschetta smeared with a little Dijon mustard and topped with Brie in place of the Gruyère croutons.
For a luxurious touch, add a dash of Cognac to each serving when you ladle on the soup.
For a lighter version, serve the soup unadorned except for a sprinkling of fresh minced parsley. Pass thin bruschetta or lightly toasted French bread and a small bowl of grated Parmesan at the table.
You may also wish to serve the soup from a tureen for a communal dining experience.
Try Julia Child's version: beat a couple of egg yolks with 4 or 5 tablespoons of port or Madeira, pour under the edge of the crust, and gently stir just before serving.
