Ingredients
Method
- Heat olive oil and butter in a pot. Add sliced onions with salt. Cook 25–30 minutes until golden brown.
- Stir in garlic. Cook 2–3 minutes. Pour in wine and simmer 5 minutes until reduced.
- Add stock, bay leaf, thyme, salt, and pepper. Simmer 20 minutes uncovered.
- Preheat oven to 180 °C (350 °F). Toast baguette slices 8–10 minutes. Ladle soup into bowls, top with baguette and Parmesan. Garnish with parsley if desired.
Notes
For a more authentic Italian presentation, serve the soup in oven-proof bowls and broil briefly after topping with bread and cheese until bubbly and golden.
