Preparation
- Slice the onions thinly and melt butter in a large pot or Dutch oven over medium heat.
- Add the sliced onions to the pot and cook, stirring occasionally, for 20-25 minutes until caramelized and deeply golden brown.
- Pour in the dry white wine, scraping any browned bits from the bottom of the pot, and cook for 2 minutes.
- Stir in the beef broth and bring the soup to a simmer, then reduce heat and let it cook for another 15-20 minutes.
- Preheat your oven broiler and arrange baguette slices on a baking sheet, then toast until golden.
- Ladle the hot soup into oven-safe bowls, place a toasted baguette slice on top of each, and sprinkle generously with Gruyère cheese.
- Broil for 2-3 minutes, or until the cheese is melted and bubbly, then serve immediately.
Notes
For extra flavor, you can add a pinch of fresh thyme to the soup while it simmers or a splash of brandy instead of white wine. Ensure your oven-safe bowls can withstand high heat under the broiler.
