Ingredients
Units
Scale
- 2 tbsp butter
- 1 tbsp olive oil
- 4 large yellow onions, thinly sliced
- 1 tsp sugar
- 1/2 tsp salt
- 2 cloves garlic, minced
- 1/2 cup dry white wine (optional)
- 6 cups beef broth
- 1 tsp dried thyme
- 1 bay leaf
- Salt and pepper to taste
- 1 baguette, sliced and toasted
- 1 1/2 cups shredded Gruyère or Swiss cheese
Instructions
- In a large pot, melt butter with olive oil over medium heat. Add onions, sugar, and salt, and cook, stirring occasionally, until onions are deeply golden and caramelized, about 30-40 minutes.
- Add garlic and cook for 1 minute. Deglaze with white wine if using, scraping up any browned bits from the bottom of the pot. Simmer for 2-3 minutes.
- Add beef broth, thyme, and bay leaf. Bring to a simmer and cook for 20-25 minutes. Remove bay leaf and season with salt and pepper to taste.
- Preheat the broiler. Ladle soup into oven-safe bowls, top each with a slice of toasted baguette, and sprinkle generously with cheese.
- Broil for 2-4 minutes, or until cheese is melted and bubbly. Serve hot.
Notes
- For vegetarian version, use vegetable broth and omit cheese or use plant-based alternative.
- Use a mix of onions (yellow and sweet) for added depth of flavor.
- Soup base can be made ahead and refrigerated for up to 3 days.
