Equipment
- Large pot For cooking the soup
- Baking sheet For broiling the cheese toast
- Ladle For serving
Ingredients
- 2 tablespoons butter
- 2 tablespoons olive oil
- 4 large yellow onions thinly sliced
- 1 teaspoon salt adjust to taste
- ½ teaspoon black pepper adjust to taste
- ½ teaspoon sugar helps caramelize the onions
- ½ cup white wine dry, such as Sauvignon Blanc
- 4 cups beef broth
- 1 bay leaf
- 1 teaspoon fresh thyme or ½ teaspoon dried thyme
- 1 baguette sliced into rounds
- 1.5 cups Gruyère cheese grated
Instructions
- Heat butter and olive oil in a large pot over medium heat. Add sliced onions, salt, black pepper, and sugar. Cook, stirring occasionally, until caramelized and golden brown, about 30 minutes.
- Pour in white wine and stir, scraping up any browned bits from the bottom of the pot. Let it simmer for 2-3 minutes until reduced.
- Add beef broth, bay leaf, and thyme. Bring to a simmer and cook for another 20 minutes to blend the flavors.
- Meanwhile, preheat the broiler. Arrange baguette slices on a baking sheet and toast until lightly golden. Sprinkle with grated Gruyère and broil until bubbly and melted.
- Remove the bay leaf from the soup and adjust seasoning as needed. Ladle into bowls, top with cheese toast, and serve warm.
Notes
- For a deeper flavor, use a mix of beef and chicken broth.
- Leftovers store well in the fridge for up to 3 days.
- Serve with a fresh salad or roasted vegetables for a balanced meal.
