Ingredients
Scale
- 4 large yellow onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 3 garlic cloves, minced
- 6 cups beef broth
- 1/2 cup dry white wine (optional)
- 2 bay leaves
- 2 teaspoons fresh thyme, chopped or 4 sprigs
- Salt and freshly ground black pepper, to taste
- 1 small baguette, cut into 1/2-inch thick slices
- 2 cups Gruyere cheese, shredded
Instructions
- Peel and thinly slice about 4 large yellow onions evenly; this takes about 10 minutes.
- In a large heavy-bottomed pot, melt 4 tablespoons unsalted butter with 1 tablespoon olive oil over medium heat. Add onions and a pinch of salt. Stir frequently every 5 minutes for 35-40 minutes until onions are deep golden brown and caramelized.
- Add 3 minced garlic cloves and cook for 1 minute until fragrant. Pour in 1/2 cup dry white wine (or substitute) to deglaze the pot, scraping up brown bits. Simmer for 3-4 minutes until mostly evaporated.
- Add 6 cups beef broth, 2 bay leaves, and 2 teaspoons chopped fresh thyme. Bring to a gentle simmer and cook uncovered for 20 minutes. Season with salt and pepper to taste.
- Preheat oven broiler. Arrange baguette slices on a baking sheet and toast for 1-2 minutes per side until golden.
- Remove toasted baguette slices and sprinkle generously with shredded Gruyere cheese.
- Place cheese-topped baguette slices back under broiler for 2-3 minutes until cheese bubbles and browns slightly. Watch closely to avoid burning.
- Ladle hot soup into oven-safe bowls. Float one or two Gruyere toasts on top of each bowl. Optionally, broil the soup bowls with toast on top for 1-2 minutes for an extra melty finish.
Notes
Slow caramelizing onions is key to avoid bitterness. Watch broiler closely when melting cheese to prevent burning. Use vegetable broth and skip wine for vegetarian version. Toast bread separately before adding cheese to avoid sogginess.
