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 grape juice mixed with a dash of apple cider vinegar (alcohol-free substitute)
- 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 salt and pepper and cook until softened. Add sugar and stir until golden brown and caramelized, about 25 minutes.
- Thicken and simmer: Add the flour and cook for 3 minutes. Add beef broth, grape juice mixture, 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, brush with melted butter on both sides, and bake for 15 minutes, flipping halfway. Rub with a cut clove of garlic.
- Broil: Turn oven to High broil. Remove bay leaves and celery. Ladle soup into 4 oven-proof bowls, top with toasted bread, sprinkle with cheese, and broil until 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 for up to 3 months.
