INGREDIENTS:
- 2 Tbsp unsalted butter
- 3 onions, sliced
- 1/2 cup red wine
- 7 cups unsalted beef broth
- Salt and freshly ground pepper
- 16 slices baguette
- 14 oz Gruyere, grated
DIRECTIONS:
In a large heavy pot over medium-high heat, melt butter. Add onions, reduce heat to medium and cook onions, stirring often, until they are lightly browned, about 30 minutes.
Add wine and cook until evaporated, about 2 minutes. Add broth, salt and pepper. Increase heat to high and bring to a boil. Reduce to low and simmer, about 15 minutes.
Preheat oven to 400 degrees.
Place baguette slices on a baking sheet and toast in oven.
Place 1 baguette slice in bottom of each of four ovenproof crocks.
Add 1/4 cup of grated cheese to each crock and place crocks on a baking sheet. Ladle soup into crocks. Top with remaining grated cheese.
Bake until cheese is beautifully browned, about 25 minutes. Serve with remaining baguette slices.
