Ingredients

¼ cup unsalted butter or olive oil
4 sweet onions thinly sliced
2 large garlic cloves chopped
2 bay leaves
2 fresh thyme sprigs
1 teaspoon salt
½ teaspoon pepper
1 cup red wine
3 heaping tablespoons all-purpose flour
8 cups beef stock
6 baguette slices
½ pound swiss cheese

Instructions

Melt butter in a large pot over medium heat. Add the onions, garlic, bay leaves, thyme, salt, and pepper and cook until onions are soft and caramelized, about 30 minutes.
Add wine, bring to a boil then reduce heat to simmer, stirring occasionally, until the wine has evaporated and onions start to dry.
Discard bay leaves and thyme sprigs. Sprinkle flour over onions and cook stirring so the flour doesn't burn for about 10 minutes to cook out the raw flour taste.
Add the beef broth 1 cup at a time, stirring well while doing so. Bring the soup back to a boil. Reduce the heat and simmer another 10 minutes.
Place the soup in oven-safe bowls on a large baking sheet. Arrange bread slices on top of the soup and sprinkle with the cheese.
Preheat the oven on broil.
Broil for 3 minutes or until bubbly and golden
