Easy French Onion Soup

Step 1: Caramelize the Onions

Start by heating the butter and olive oil in a large pot or Dutch oven over medium heat. Once the butter has melted, add the sliced onions to the pot. Cook the onions slowly, stirring occasionally, for about 20-25 minutes. The goal is to caramelize the onions, which will deepen their flavor and turn them a rich golden brown. Be patient and stir occasionally to prevent burning.

Step 2: Add the Broth and Wine

Once the onions are caramelized and deeply golden, add the wine (if using) to deglaze the pot, scraping up any browned bits from the bottom. Let it simmer for about 2-3 minutes to reduce slightly. Then, add the beef broth, fresh thyme, and bay leaf. Stir to combine and bring the soup to a simmer.

Let the soup simmer gently for 20-30 minutes to allow the flavors to meld together. Taste the soup and add salt and pepper to your liking.

Step 3: Toast the Bread

While the soup is simmering, preheat your oven’s broiler. Place the slices of baguette on a baking sheet and toast them under the broiler for 2-3 minutes on each side, or until golden brown and crispy. Watch closely to avoid burning!

Step 4: Assemble the Soup

Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, leaving a little space at the top for the bread and cheese. Place a toasted baguette slice on top of each bowl of soup. Then, sprinkle a generous amount of shredded Gruyère cheese (and Parmesan, if using) on top of the bread.

Step 5: Broil the Soup

Place the bowls under the broiler for 3-5 minutes, or until the cheese is bubbly, melted, and golden brown. Be sure to keep an eye on them so they don’t burn.

Step 6: Serve and Enjoy

Carefully remove the hot bowls from the oven and let them cool slightly before serving. The cheese should be gooey, and the bread should be soft underneath but crisp on top. Enjoy your warm, comforting bowl of Easy French Onion Soup!

Tips for Making the Best French Onion Soup

• Caramelizing the Onions: The key to the best French Onion Soup is properly caramelizing the onions. Don’t rush this process—it can take up to 30 minutes, but the result will be deeply sweet and flavorful onions that make the soup rich and delicious.
• Broth: While beef broth is traditional and gives the soup its signature deep flavor, you can substitute with chicken broth or vegetable broth for a lighter version. Just be sure to use a high-quality broth for the best results.
• Wine: While wine adds an extra layer of depth to the soup, if you prefer not to use alcohol, you can substitute with additional broth or a splash of balsamic vinegar for a similar tangy effect.
• Cheese: Gruyère is the classic cheese for French Onion Soup because it melts beautifully and has a rich, nutty flavor. Swiss cheese is a good substitute, or you can use a combination of both for extra flavor.
• Bread: The bread topping is an essential part of the soup. Use a hearty, crusty bread like a baguette or sourdough for the best texture. You can also rub the bread with a clove of garlic before toasting for an added burst of flavor.

Variations of French Onion Soup

While the classic version is perfect as is, here are some fun variations to try:

• Onion Soup with Bacon: Add cooked, crumbled bacon to the soup after the onions have caramelized for a smoky, savory twist.
• French Onion Soup with Herbs: Add a few sprigs of rosemary or a bay leaf during the simmering stage for a deeper, more aromatic flavor.
• Vegan French Onion Soup: Use vegetable broth instead of beef broth, and skip the cheese topping, or use a vegan cheese alternative to keep it plant-based.
