Ingredients
-
3 tablespoons butter
-
1/2 tablespoon olive oil
-
2 pounds (about 3) yellow onions, thinly sliced
-
1/2 teaspoon granulated white sugar
-
1/4 teaspoon salt
-
1/8 teaspoon pepper
-
2 tablespoons all-purpose flour
-
6 cups beef broth
-
1 whole bay leaf
-
8 slices baguette
-
4 ounces (1 cup) grated Gruyère cheese
-
1 ounce (1/4 cup) freshly grated Parmesan cheese
-
Fresh thyme for garnish (optional)
Instructions
-
Cook Onions: In a large pot, melt butter and olive oil over medium heat. Add sliced onions, sugar, salt, and pepper. Cook for 25-30 minutes, stirring frequently, until onions are golden and caramelized.
-
Add Flour: Sprinkle flour over onions and stir to combine. Cook for 2 minutes to form a roux.
-
Simmer Soup: Gradually add beef broth while stirring, scraping up any bits stuck to the bottom. Add bay leaf and bring to a simmer. Let cook for 20-25 minutes.
-
Prepare Bread: While the soup simmers, toast the baguette slices in the oven or on a pan until golden and crispy.
-
Assemble & Bake: Preheat broiler. Ladle soup into oven-safe bowls. Place a slice of toasted baguette on top of each bowl, and sprinkle with Gruyère and Parmesan. Broil for 3-5 minutes, until the cheese is melted and bubbly.
-
Serve: Garnish with fresh thyme, if desired. Serve hot and enjoy!
Notes
-
For a lighter version, you can use low-sodium beef broth.
-
You can also use Swiss cheese or a blend of cheeses if Gruyère is unavailable.
-
Make sure to toast the baguette slices until they are crispy to prevent them from becoming soggy when added to the soup.
