Classic French Onion Soup Recipe: A Warm and Flavorful Delight

Instructions

Step 1: Caramelize the Onions

1. Heat butter and olive oil in a large pot over medium heat.
2. Add the sliced onions and cook, stirring occasionally, until softened (about 10 minutes).
3. Sprinkle in the sugar and continue cooking, stirring more frequently, until the onions are deeply golden and caramelized (about 30–40 minutes).

Step 2: Build the Flavor

1. Add the minced garlic to the pot and cook for 1–2 minutes until fragrant.
2. Sprinkle the flour over the onions, stirring to coat evenly. Cook for 1–2 minutes to eliminate the raw flour taste.
3. Deglaze the pot with white wine (if using), scraping up any browned bits from the bottom of the pot. Allow the wine to simmer for 2–3 minutes.

Step 3: Simmer the Soup

1. Pour in the beef broth, and add the bay leaf and thyme.
2. Bring the mixture to a gentle boil, then reduce the heat to low and let it simmer for 20–30 minutes to develop the flavors.
3. Season with salt and pepper to taste, and remove the bay leaf before serving.

Step 4: Assemble and Broil

1. Preheat your oven’s broiler.
2. Ladle the soup into oven-safe bowls. Place a slice of toasted baguette on top of each bowl, and generously sprinkle Gruyère cheese over the bread.
3. Place the bowls under the broiler for 3–5 minutes, or until the cheese is melted and bubbly with golden spots.

Tips for the Best French Onion Soup

• Onion choice: Yellow onions work best for their sweetness and balance.
• Broth quality: A good-quality beef broth makes all the difference in flavor.
• Cheese options: While Gruyère is traditional, you can also use Swiss or a mix of Gruyère and Parmesan for a twist.
