Heat a large Dutch oven or heavy-bottomed pot over medium heat. Add the butter and olive oil, letting the butter melt completely.
Add the sliced onions to the pot and stir to coat them evenly with butter and oil.
Sprinkle the onions with the sugar, which helps with caramelization. Cook the onions over medium to medium-low heat, stirring occasionally, for about 25-30 minutes, or until they are deeply golden brown and caramelized.
Add the minced garlic to the onions and cook for another 1-2 minutes, stirring frequently.
Sprinkle the caramelized onions with the flour and cook, stirring constantly, for 2 minutes to eliminate the raw flour taste.
Deglaze the pot by adding the wine, scraping the bottom of the pot with a wooden spoon to loosen any browned bits.
Pour in the beef broth and add the thyme and bay leaf. Stir to combine and bring the soup to a gentle simmer. Reduce the heat to low and let it simmer for 20-25 minutes. Season with salt and pepper to taste.
While the soup is simmering, preheat the oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast in the oven for 5-7 minutes, flipping halfway through, until lightly golden and crisp.
Ladle the soup into oven-safe bowls and place one or two baguette slices on top of each bowl.
Sprinkle a generous amount of shredded Gruyere cheese over the baguette slices.
Place the bowls on a baking sheet and transfer to the oven. Broil on high for 2-3 minutes, or until the cheese is melted and bubbly. Keep an eye on it to avoid burning.
Carefully remove the hot bowls from the oven and serve the soup immediately, garnished with additional thyme if desired.
