Ingredients

• 4 large onions, thinly sliced
• 2 tbsp butter
• 1 tbsp olive oil
• 2 cloves garlic, minced
• 1 tsp fresh thyme (or 1/2 tsp dried thyme)
• 1 bay leaf
• 4 cups beef broth
• 1 cup chicken broth
• 1/2 cup dry white wine (optional)
• Salt and pepper to taste
• 8 slices of toasted baguette or French bread
• 1 1/2 cups shredded Gruyère cheese

Instructions

1. Caramelize the Onions: In a large pot, melt the butter with olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until caramelized and golden brown, about 30-40 minutes. This step is crucial, as the sweetness of the caramelized onions is the base of the soup’s flavor.
2. Add Garlic and Herbs: Stir in the minced garlic, thyme, and bay leaf. Cook for another minute to release the flavors, making sure the garlic doesn’t burn.
3. Add Broth and Simmer: Pour in the beef broth, chicken broth, and wine (if using). Bring the mixture to a boil, then reduce heat and let it simmer for 15-20 minutes. Season with salt and pepper to taste.
4. Prepare for Broiling: Preheat your broiler. Ladle the soup into oven-safe bowls. Top each with a slice of toasted bread and a generous sprinkle of shredded Gruyère cheese.
5. Broil the Soup: Broil for 2-3 minutes until the cheese is melted and bubbly. Keep a close eye on it to prevent burning!
6. Serve: Carefully remove the bowls from the oven, let cool slightly, and serve hot.

Recipe Variations

• Vegetarian Option: Use vegetable broth instead of beef and chicken broth for a vegetarian version. You can also add mushrooms for an earthy flavor.
• Add Protein: Incorporate cooked chicken or beef for a heartier soup.
• Spice It Up: Add a pinch of cayenne pepper for a slight kick.
• Baked Variation: Instead of broiling, you can bake the soup in the oven at 350°F (175°C) until the cheese is melted and bubbly.

Serving Suggestions

• With Crusty Bread: Serve with a side of crusty baguette for dipping.
• As a Starter: This soup makes a perfect starter for a French-inspired meal.
• Wine Pairings: Pairs well with a light red wine like Pinot Noir or a crisp white like Sauvignon Blanc.

Freezing and Storage

• Storing Leftovers: Store any leftover soup in an airtight container in the refrigerator for up to 3 days.
• Freezing: The soup can be frozen for up to 3 months. However, it’s best to freeze it without the cheese and bread, as they can become soggy when reheated.
• Reheating: To reheat, thaw in the fridge overnight, then warm gently on the stove. Top with fresh cheese and broil before serving.
