Ingredients:
- Soup:

- 3 tablespoons butter
- 4 cloves garlic, minced
- 3 tablespoons flour
- 1/2 cup dry white wine
- 6 cups beef stock (or vegetable stock)

- Fine sea salt and freshly-cracked black pepper, to taste
- Toppings:
- 1 baguette, sliced into 1-inch pieces
- Grated or sliced cheese (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 cook for about 30 minutes, stirring every 3-5 minutes initially, then more frequently as they caramelize to avoid burning.
- Once golden and soft, stir in the minced garlic and sauté for 2 minutes.
- Sprinkle in the flour, stirring constantly, and cook for 1 minute.
- Pour in the wine to deglaze the pot, scraping up browned bits from the bottom.
- Simmer the Soup:
- Add the beef stock, Worcestershire sauce, bay leaf, and thyme. Stir to combine.
- Bring the soup to a gentle simmer, then reduce the heat to medium-low. Cover and let it simmer for at least 10 minutes.
- Remove and discard the bay leaf and thyme sprigs. Season the soup with salt and pepper to taste.
- Prepare the Bread:
- Preheat the oven to 400°F (200°C).
- Arrange the baguette slices in a single layer on a baking sheet and toast for 6-8 minutes until golden and crisp. Set aside.
- Assemble and Broil:
- Switch the oven to broiler mode.
- Ladle the hot soup into oven-safe bowls placed on a sturdy baking sheet.
- Top each bowl with a toasted baguette slice and a generous amount of grated or sliced cheese (about 1/4 cup per bowl).
- Place the bowls under the broiler about 6 inches from the heat and broil for 2-4 minutes, until the cheese is melted and bubbly. Watch closely to avoid burning.
- Serve:
- Carefully remove the bowls from the oven and serve immediately while hot and bubbling.
