Slice the onions into thin half-moons.
Soften the onions in the butter and olive oil in a covered pot for 10 minutes.
Add the sugar and cook the onions for 30 minutes, stirring often, until deep golden.
Add the garlic and flour and toast for 2 minutes.
Add the white wine and scrape up the caramelized bits from the bottom of the pot.
Add the beef stock and thyme, then simmer over low heat for 25 minutes.
Toast the baguette slices, divide the soup among bowls, and top with bread and Gruyere.
Place the bowls under the broiler for 4 minutes, until the cheese melts and browns.
💡 Tip: Cooking the onions to a deep golden color without burning builds the soup's sweet, savory base.
🍽️ Serving suggestion: Serve as soon as it comes from the oven, while the cheese is still bubbling.
