Step-by-Step Instructions
- In a large skillet, melt butter and olive oil over medium-low heat. Add sliced onions, thyme, and bay leaf. Cook slowly, stirring every 10 minutes, for about 45 minutes until caramelized.
- Pour white wine to deglaze the pan, scraping up bits. Simmer for 2-3 minutes, then add beef broth and bring to a gentle boil. Simmer for another 15 minutes.
- Preheat oven's broiler. Divide hot soup into oven-safe bowls. Top each with toasted baguette slices and sprinkle with grated Gruyère cheese.
- Place bowls under the broiler for 3-5 minutes until cheese is bubbly and golden.
- Remove from oven, garnish with thyme, and serve hot.

Notes
For best results, watch the broiler closely while melting the cheese to avoid burning.
