Onion Preparation

1. Slice the Onions

Peel and thinly slice the yellow onions.

2. Cook the Onions

In a large pot, heat the butter and olive oil over medium heat. Add the sliced onions and stir to coat them in the fat. Sprinkle with salt and sugar.

3. Caramelize the Onions

Cook the onions, stirring frequently, for about 30-40 minutes until they are soft, golden brown, and caramelized. Add the thyme leaves in the last few minutes of cooking.

Soup Base

4. Add Broth and Wine

Once the onions are caramelized, pour in the beef broth and dry white wine. Stir to combine.

5. Season the Soup

Add Worcestershire sauce and black pepper. Bring the mixture to a simmer and let it cook for about 15 minutes.

Toppings

6. Prepare the Bread

Preheat your oven to 375°F (190°C). Toast the baguette or crusty bread slices until they are slightly crispy.

7. Assemble the Dish

Ladle the soup into oven-safe bowls, place a slice of toasted bread on top of each bowl, and generously sprinkle with Gruyère and Parmesan cheese.

8. Bake

Place the bowls on a baking sheet and bake in the oven for about 10-15 minutes, or until the cheese is melted and bubbly.
