Instructions
- In a large pot over medium heat, melt the butter with olive oil. Add the sliced onions and cook, stirring occasionally, until they begin to soften, about 10 minutes.
- Reduce the heat to low, add the sugar, and continue to cook the onions until they are deeply caramelized, stirring frequently for about 30-35 minutes. This step requires patience, but the reward is golden and flavorful onions.
- Stir in the minced garlic and cook for another minute until fragrant.
- Add the white wine to deglaze the pot, scraping up any brown bits from the bottom. Let it simmer for 2-3 minutes until reduced by half.
- Pour in the beef broth and add the thyme. Season with salt and pepper to taste. Bring the soup to a simmer and let it cook for 20 minutes, allowing the flavors to meld together.
- Preheat your oven’s broiler. Ladle the soup into oven-safe bowls, place a slice of toasted baguette on top of each, and generously sprinkle with Gruyère cheese.
- Place the bowls on a baking sheet and broil in the oven until the cheese is bubbly and golden brown, about 3-5 minutes. Keep a close eye to prevent burning.
Each step is a tribute to the lessons I’ve learned in my kitchen: patience, attention to detail, and the joy of creating something delicious from scratch.
