Caramelize the onions

To achieve the rich and sweet flavor of French onion soup, you’ll need to caramelize the onions. Start by thinly slicing the onions and melting butter in a large skillet over medium heat. Add the onions and stir occasionally until they become golden brown and soft, which usually takes around 30 minutes. The slow cooking process helps to develop the onions’ natural sweetness and deepens their flavor.

  • Thinly slice onions
  • Melt butter in a skillet
  • Add onions and cook until golden brown and soft

Add ingredients to the slow cooker

Once the onions are caramelized, it’s time to transfer them to your slow cooker. Add the onions, beef broth, dry white wine, minced garlic, thyme, bay leaves, salt, and black pepper to the slow cooker. Give it a good stir to ensure all the ingredients are well combined and the flavors are evenly distributed. Then cover the slow cooker and set it to cook on low heat for 6-8 hours or on high heat for 4-6 hours.

  3. Stir well to combine all ingredients
  4. Cover and cook on low heat for 6-8 hours or high heat for 4-6 hours

Prepare the bread and cheese topping

While the soup is simmering in the slow cooker, it’s time to prepare the bread and cheese topping. Slice a baguette or crusty French bread into thick slices and toast them in the oven or under the broiler until they are lightly crispy. Once the soup is ready, ladle it into oven-safe bowls and place a slice of toasted bread on top of each bowl. Then sprinkle generously with grated Gruyère or Swiss cheese. Place the bowls under the broiler for a few minutes, until the cheese is melted and bubbly.

1. Caramelize the Onions

One of the key steps in making French onion soup is caramelizing the onions. This process takes time, but it’s worth it for the deep, sweet flavor it adds to the dish. Be patient and let the onions cook slowly over low heat until they are golden brown.

2. Use the Right Type of Onions

For the best flavor, use yellow onions when making French onion soup. They have a milder taste compared to red onions and will caramelize beautifully. Avoid using sweet onions, as they can make the soup too sweet.

3. Add a Splash of Wine

A splash of dry white wine or sherry can take your French onion soup to the next level. The acidity and depth of flavor from the wine will enhance the overall taste of the soup. Just a small amount is enough to make a difference.

4. Don’t Forget the Beef Broth

Beef broth is what gives French onion soup its savory, meaty flavor. Opt for a high-quality beef broth or make your own from scratch for the best results. If you prefer a vegetarian version, you can use vegetable broth instead.

5. Toast the Bread and Melt the Cheese

A classic French onion soup is topped with a slice of toasted baguette and melted cheese. To achieve the perfect texture, toast the bread slices before adding them to the soup. When it’s time to serve, sprinkle cheese on top and broil the soup in the oven until the cheese is bubbly and golden.
