Ingredients You’ll Need:
- 1 package of Costco French Onion Soup
- 2 tablespoons of butter
- 2 large yellow onions, sliced thinly
- 1 cup of dry white wine (optional)
- 4 cups of beef broth
- 1 bay leaf
- Salt and pepper to taste
- 8 slices of French bread
- 1 cup of shredded Gruyère cheese
Step-by-Step Instructions:
1. Sauté the Onions:
In a large pot or Dutch oven, melt the butter over medium heat. Add the sliced onions and cook until they become translucent and caramelized, about 15-20 minutes.
2. Add the Wine (Optional):
If desired, pour in the dry white wine and let it simmer for a few minutes to reduce and enhance the flavor.
3. Pour in the Beef Broth:
Add the beef broth and bay leaf to the pot and bring to a boil. Reduce heat and simmer for at least 30 minutes, or up to an hour for a richer flavor.
4. Season to Taste:
Season the soup with salt and pepper to your preference. Taste and adjust as needed.
5. Prepare the French Bread:
Slice the French bread into 8 slices and toast them in a toaster or oven until golden brown.
6. Assemble the Soup:
Ladle the soup into individual soup bowls and top with a toasted slice of French bread.
7. Sprinkle with Cheese:
Generously sprinkle the shredded Gruyère cheese over the soup and bread.
8. Broil or Bake:
Place the soup bowls under a broiler or in a preheated oven at 350°F (175°C) until the cheese is melted and bubbly.
Tips for Perfection:
- Use a variety of onions for a more complex flavor, such as yellow, white, and red.
- Cook the onions slowly and patiently to achieve a deep caramelization.
- Don’t be afraid to experiment with different types of cheese, such as mozzarella or cheddar.
- Serve the soup immediately for the best flavor and texture.
Variations:
- Add sautéed mushrooms or chopped bacon to the soup for an extra layer of savory richness.
- Use a vegetable broth instead of beef broth for a vegetarian option.
- Top the soup with a dollop of sour cream or a sprinkle of fresh parsley for a refreshing contrast.
