Ingredients
- 4 large yellow onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 4 cups beef broth
- 1 cup white wine (optional)
- 2 tsp sugar
- 1 bay leaf
- 1 sprig fresh thyme
- Salt and pepper, to taste
- 4 slices baguette, toasted
- 1 ½ cups Gruyère cheese, grated
- Thomy Twist: Drizzle of truffle oil or a sprinkle of crisped pancetta (optional)
Instructions
- Heat butter and olive oil in a large pot over medium heat. Add the onions and cook, stirring occasionally, for 20-25 minutes, or until the onions are deeply caramelized and golden brown.
- Sprinkle the sugar over the onions to help with caramelization and stir well.
- Add the white wine (if using) and scrape up any bits from the bottom of the pot. Let the wine reduce for 3-4 minutes.
- Add the beef broth, bay leaf, and thyme to the pot. Bring to a simmer and cook for 30 minutes. Remove the bay leaf and thyme sprig and season with salt and pepper.
- Preheat your oven to 400°F (200°C). Ladle the soup into oven-safe bowls, then place a slice of toasted baguette on top of each. Sprinkle with Gruyère cheese.
- Place the bowls in the oven and bake for 10-15 minutes, or until the cheese is melted and golden brown. Alternatively, place under the broiler for 2-3 minutes, if preferred.
- For the Thomy Twist, drizzle truffle oil or sprinkle crisped pancetta on top before serving to elevate the flavor and richness.
- Serve hot, garnished with fresh thyme, if desired.
