• 2 cloves garlic, minced
• 1 teaspoon sugar
• 6 cups beef broth (or vegetable broth for a vegetarian option)
• 1 teaspoon Worcestershire sauce

How to Make French Onion Soup

Step 1: Caramelize the Onions

The secret to a truly delicious French onion soup lies in the caramelization of the onions. Heat a large pot over medium-low heat and add the butter and olive oil. Once the butter is melted, add the sliced onions. Stir them well to coat in the fat.

Let the onions cook slowly, stirring occasionally. After about 10 minutes, add the sugar and a pinch of salt to help draw out their natural sweetness. Continue cooking for another 30–40 minutes, stirring frequently, until the onions turn a deep golden brown. Be patient—this step is key to developing the rich flavor!

Step 2: Build the Broth

Once the onions are beautifully caramelized, add the minced garlic and cook for another minute until fragrant. Then, pour in the Worcestershire sauce, scraping up any browned bits from the bottom of the pot.

Next, add the beef broth, dried thyme, black pepper, salt, and bay leaf. Stir everything together, bring the soup to a gentle simmer, and let it cook for 20–25 minutes to allow the flavors to meld.

Step 3: Prepare the Bread and Cheese Topping

While the soup simmers, preheat your oven to 375°F (190°C). Arrange the baguette slices on a baking sheet and toast them for about 8–10 minutes, flipping halfway through, until they’re crisp and golden.

Once toasted, remove them from the oven and set them aside.

Step 4: Assemble and Broil

Ladle the hot soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl, then generously sprinkle the shredded Gruyère cheese over the bread.

Place the bowls on a baking sheet and transfer them to the oven. Broil for 3–5 minutes, or until the cheese is melted, bubbly, and golden brown. Watch closely to avoid burning!

Step 5: Serve and Enjoy

Carefully remove the soup from the oven (it will be hot!) and let it cool slightly before serving. The cheese will be gooey, the bread will be soaked in delicious broth, and the rich, caramelized onion soup underneath will be absolutely irresistible.

Helpful Tips for the Best French Onion Soup

• Be patient with the onions – The longer they caramelize, the richer and deeper the flavor. Don’t rush this step!
• Use a good-quality broth – Since this soup relies on simple ingredients, a flavorful broth makes all the difference.
• Toast the bread well – If the bread isn’t toasted enough, it can become too soggy in the soup. A crisp baguette slice holds up best.
• Use oven-safe bowls – If you don’t have broiler-safe soup bowls, you can melt the cheese on the bread separately and then place it on top of the soup before serving.

Frequently Asked Questions

Can I make this soup ahead of time?

Yes! The soup itself can be made in advance and stored in the refrigerator for up to 3 days. When ready to serve, reheat it on the stovetop and prepare the bread and cheese topping fresh.

Can I freeze French onion soup?

What can I use instead of Gruyère cheese?

Swiss, mozzarella, or even sharp cheddar can work as substitutes. Gruyère has a nutty, slightly sweet flavor that’s classic for this soup, but other cheeses will still be delicious.

Use gluten-free bread for the topping, and double-check that your Worcestershire sauce and broth are gluten-free.
