Stir occasionally during the cooking process.

Continue to cook until all the wine has reduced, about 15 to 20 minutes.

10
Arrange the bread on a cookie sheet and bake until slightly browned.
11
Once browned, remove them from the oven.

Heat the broiler.

Ladle onion soup into crocks or bowls, leaving enough room for the toasted baguette.
