French Onion Soup

Instructions

1. Caramelize the Onions:

• In a large pot or Dutch oven, heat the butter and olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, for about 10-15 minutes until softened.
• Add the sugar and continue to cook, stirring frequently, for another 20-30 minutes until the onions are golden brown and caramelized. Be patient—this step is key to developing the soup’s deep, rich flavor.

1. Deglaze the Pan:

• Stir in the minced garlic and cook for another minute. If using white wine, pour it in to deglaze the pan, scraping up any browned bits from the bottom. Let the wine simmer for 2-3 minutes until mostly evaporated.

1. Make the Soup:

• Add the beef broth, thyme, and bay leaf to the pot. Bring to a boil, then reduce the heat and let it simmer uncovered for 30 minutes. Season with salt and pepper to taste. Discard the thyme sprigs and bay leaf.

1. Prepare the Baguette Topping:

• While the soup is simmering, preheat your oven to 400°F (200°C). Place the baguette slices on a baking sheet and toast them in the oven for 5-7 minutes until crisp.

1. Assemble and Broil:

• Preheat the broiler. Ladle the soup into oven-safe bowls, top each with a toasted baguette slice, and sprinkle a generous amount of grated cheese over the top.
• Place the bowls under the broiler for 2-4 minutes, until the cheese is melted, bubbly, and golden brown. Watch carefully to avoid burning.

1. Serve Immediately:

• Carefully remove the bowls from the oven and serve the soup hot. Garnish with extra thyme leaves if desired.

Tips for the Perfect French Onion Soup

• Caramelizing the Onions: Don’t rush the caramelization process. Slow-cooking the onions over medium heat brings out their natural sweetness and creates the foundation for a flavorful soup.
• Choosing the Cheese: Gruyère cheese is traditional for French Onion Soup, offering a perfect balance of nuttiness and meltability. Swiss cheese, mozzarella, or even a mix of cheeses can be used if you prefer.
• Broth Quality: Using a high-quality beef broth or stock will make a significant difference in taste. If you want a deeper flavor, you can use a combination of beef and chicken broth.

Variations to Try

• Vegetarian French Onion Soup: Swap the beef broth for a rich vegetable broth and add a splash of soy sauce or Worcestershire sauce for extra depth.
• Add a Splash of Cognac: For an extra touch of richness, stir in a tablespoon of cognac or brandy right before serving.
• Experiment with Toppings: Try adding a sprinkle of fresh herbs like chives or rosemary on top for a different twist.
