Ingredients
Scale
- 5 large yellow onions, thinly sliced
- 32 oz low-sodium beef broth
- 24 oz low-sodium chicken broth
- 1 ½ cups shredded Gruyere Swiss cheese, room temperature
- ¼ cup shredded Mozzarella cheese, room temperature
- 4 tablespoons butter
- 2 tablespoons finely grated Parmesan cheese, room temperature
- 2 tablespoons virgin olive oil
- 1 tablespoon Worcestershire sauce
- ½ tablespoon balsamic vinegar
- 1 teaspoon minced garlic
- 1 teaspoon salt
- 1 teaspoon granulated sugar
- 2 sprigs fresh thyme
- 1 bay leaf
- 5 thick slices of French bread
- Salt and black pepper to taste
Instructions
- Caramelizing Onions: Melt the butter in a large pot over medium-high heat. Add the thinly sliced onions and sauté for about 10 minutes until they soften. Stir in the salt and sugar, reduce the heat to medium, and continue cooking for 35 minutes, occasionally stirring, until the onions are caramelized and almost syrupy.
- Adding Broth and Seasonings: Stir in the minced garlic and cook until fragrant, about 1 minute. Then add the beef and chicken broth, Worcestershire sauce, fresh thyme, and bay leaf. Allow the mixture to gently simmer over medium to medium-low heat for 20 minutes, stirring occasionally.
- Final Soup Preparation: Remove and discard the thyme and bay leaf. Stir in the balsamic vinegar and taste the soup to adjust seasoning with additional salt and pepper if needed. Keep the soup covered and heated on low while preparing the bread.
- Preparing Toasted Bread: Preheat the oven broiler and arrange the bread slices on a baking sheet. Brush each side with olive oil and broil for 2-3 minutes, flipping once. Watch closely to prevent burning.
- Assembling and Broiling the Soup: Place oven-safe bowls on a baking sheet, fill each two-thirds full with the hot soup, and top with a slice of toasted bread. Generously sprinkle with Swiss, Mozzarella, and Parmesan cheeses. Broil until the cheese is bubbly and golden brown, creating a delicious crusty seal around the bowl edges.
