INGREDIENTS
- 4 pounds yellow onions, peeled and thinly sliced (approximately 5–6 large onions)
- 3 tablespoons butter
- 4Â cloves garlic, minced
- 3 tablespoons flour
- 1/2 cup dry white wine
- 6 cups of beef stock (or veggie stock)
- 1 teaspoon Worcestershire sauce
- 1Â bay leaf
- 3 sprigs fresh thyme (or 1 teaspoon dried thyme)
- fine sea salt and freshly-cracked black pepper, to taste
- baguette
- grated or sliced cheese (such as Gruyere, Asiago, Swiss, Gouda or Mozzarella)
INSTRUCTIONS
- Caramelize the onions. In a large heavy-bottomed stockpot, melt the butter over medium-high heat.  Add the onions and sauté until well for about 30 minutes until caramelized (but not burnt), initially stirring every 3-5 minutes, then about once a minute near the end of caramelization to prevent burning*. Add garlic and sauté for 2 minutes.  Stir in the flour and cook for an additional 1 minute.  Stir in the wine to deglaze the pan, using a wooden spoon to scrape up any browned bits on the bottom of the pan.
- Simmer the soup. Add the stock, Worcestershire, bay leaf, and thyme and stir to combine. Continue to cook until the soup reaches a simmer.  Then reduce heat to medium-low, cover and simmer for at least 10 minutes. Discard the bay leaf and sprigs of thyme. Taste the soup and season with salt and pepper as needed.
- Toast the bread.  Preheat oven to 400°F.  While the soup is simmering, slice the baguette into 1-inch thick pieces and arrange them in single layer on baking sheet.  Bake for 6-8 minutes, until the bread is toasted and golden around the edges.  Remove and set aside.
- Broil the topping. Switch the oven to the broiler. Once the soup is ready to serve, place your oven-safe bowls on a thick baking sheet.  Ladle the soup into each bowl, then top with a baguette slice and your desired amount of cheese (I used about 1/4 cup shredded cheese for each).  Place on an oven rack about 6 inches from the heat and broil for 2-4 minutes, or until the cheese is melted and bubbly. (Keep a close eye on them so that they do not burn.) Remove from the oven and serve immediately while the soup is hot and bubbly.
