Ingredients
Scale
- 1 1/2 pounds onions, thinly sliced
- 3 Tablespoons butter
- 1/4 teaspoon granulated sugar
- 1/4 teaspoon salt
- 2 Tablespoons all-purpose flour
- 6 cups low-sodium beef broth
- 1/2 cup white grape juice
- 1/2 teaspoon dried thyme
- 1 piece celery, small chunk
- 2 bay leaves
- 8 slices French Baguette
- 4 Tablespoons butter, melted
- 2 cloves garlic, halved
- 1 cup Gruyere cheese, fresh grated
- 1/3 cup freshly grated parmesan cheese
Instructions
- Caramelize onions: Add butter and onions to a large pot over medium heat. Season with a little salt and pepper and cook until softened. Add sugar and continue to gently stir until onions become golden brown and caramelized, about 25 minutes.
- Thicken and Simmer: Add the flour and cook for 3 more minutes. Add beef stock, white grape juice, thyme, celery, and bay leaves. Cook partially covered for 30 minutes.
- Preheat: Preheat oven to 350 degrees F.
- Toast bread: Arrange bread on a baking sheet and brush with melted butter on both sides. Bake for 15 minutes, flipping to the other side half way through. Remove from oven and rub a cut clove of garlic onto each piece of bread.
- Broil: Turn oven to High broil. Remove bay leaves and the piece of celery from the soup and ladle soup into 4 oven proof bowls. Place the toasted bread on top of each bowl. Sprinkle the tops generously with both types of cheese. Broil until the cheese is browned and bubbling.
Notes
Cheese: Could substitute Swiss. Make Ahead: The soup base can be made a day in advance and stored in the fridge. Freezing: Store the soup, without bread and cheese, in a freezer safe container and freeze for up to 3 months.
