→ Liquids
10 - 1/2 cup dry white wine
11 - 6 cups vegetable or beef broth (low sodium)

12 - 16 oz (450 g) potato gnocchi (fresh or shelf-stable)
→ Topping
13 - 1 baguette, sliced into 1/2-inch rounds

# Method:
01 - In a large heavy-bottomed pot or Dutch oven, melt the butter with olive oil over medium heat. Add sliced onions and sauté, stirring frequently, for 10 minutes.
02 - Sprinkle onions with sugar, salt, and pepper. Continue to cook, stirring often, until onions are deeply golden and caramelized, about 20–25 minutes.
03 - Add minced garlic and thyme; cook for 1 minute until fragrant.
04 - Pour in the white wine, scraping up any browned bits from the bottom. Simmer for 2 minutes until slightly reduced.
05 - Stir in the broth and bay leaf. Bring to a simmer, cover loosely, and cook for 10 minutes. Remove bay leaf and adjust seasoning to taste.
06 - While the soup simmers, preheat oven broiler. Arrange baguette slices on a baking sheet, brush with olive oil, and toast under the broiler for 1–2 minutes per side until golden.
07 - Bring a medium pot of salted water to a boil. Cook gnocchi according to package instructions (usually 2–3 minutes, until they float). Drain and set aside.
08 - Add cooked gnocchi to the soup and heat through for 2–3 minutes.
09 - Ladle soup with gnocchi into oven-safe bowls. Top each with toasted baguette slices, sprinkle generously with Gruyère and Parmesan.
10 - Place bowls on a baking tray and broil for 2–4 minutes, until cheese is bubbly and golden.
11 - Garnish with fresh parsley and serve hot.
