Ingredients for Easy French Onion Soup

To make this delicious French onion soup, you’ll need the following ingredients:

• 3 pounds Spanish onions, sliced pole to pole into thin slices: The onions are the star of this soup, and Spanish onions are perfect for caramelizing due to their natural sweetness.
• 6 cups beef broth (48 fl oz): A high-quality beef broth serves as the flavorful base of the soup. You can use homemade or store-bought broth, but the quality will impact the final taste.
• 2 tablespoons olive oil: Olive oil helps to caramelize the onions and adds richness to the soup.
• 2 tablespoons all-purpose flour: This will be used to help thicken the soup slightly.
• 1 cup dry sherry: Dry sherry adds depth and richness to the broth and complements the sweetness of the onions.
• 4 cloves garlic (2 cloves minced and 2 cloves halved): Garlic adds an aromatic punch and enhances the flavor profile of the soup.
• 1⁄4 cup chopped fresh parsley: Fresh parsley adds a pop of color and freshness to the soup.
• 3 sprigs fresh thyme: Thyme is an essential herb in French onion soup, lending a subtle earthy flavor.
• 4 whole cloves (optional): Whole cloves add a bit of aromatic spice. This ingredient is optional but can deepen the flavor of the broth.
• 10 black peppercorns: Freshly ground black pepper provides seasoning to balance the sweetness of the onions.
• 1 Parmesan cheese rind (optional): Adding a Parmesan rind to the broth while simmering will impart a rich umami flavor.
• Kosher salt and freshly ground black pepper, to taste: These will be used to season the soup.
• 8 ounces Gruyère cheese, shredded: Gruyère cheese is the classic cheese for French onion soup, known for its nutty, slightly sweet flavor that melts beautifully.
• 1 French baguette, cut into 1⁄2 inch slices: The baguette slices will be toasted and placed on top of the soup before being broiled to perfection.
• 2 tablespoons chopped chives: Chopped chives are optional for garnish but add an extra layer of flavor and color.

How to Make Easy French Onion Soup

Now that you have all the ingredients, it’s time to make the soup. The following step-by-step instructions will guide you through the process:

Step 1: Caramelize the Onions

Start by heating the olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add the thinly sliced onions and sauté them for about 15-20 minutes, stirring occasionally. You want the onions to become golden brown and caramelized, as this process brings out their natural sweetness and creates the base for the soup’s flavor.

Once the onions are caramelized and soft, add the minced garlic and cook for another minute until fragrant.

Step 2: Make the Broth Base

Sprinkle the flour over the caramelized onions and garlic, and stir to combine. The flour will help thicken the soup. Let the flour cook for about 1-2 minutes to remove any raw taste.

Next, add the dry sherry to the pot, stirring well to combine. Allow the sherry to reduce slightly, about 3-5 minutes. This will concentrate its flavor and help deglaze the pot, lifting any flavorful bits from the bottom of the pan.

Step 3: Add the Broth and Herbs

Pour in the beef broth, stirring constantly to combine all the ingredients. Add the fresh thyme, whole cloves, black peppercorns, and Parmesan cheese rind (if using). Stir everything together and bring the soup to a simmer.

Once the soup is simmering, lower the heat to medium-low and let it cook for 30-40 minutes to allow the flavors to meld together. Be sure to taste and adjust the seasoning with kosher salt and freshly ground black pepper.

Step 4: Prepare the Topping

While the soup is simmering, preheat your oven’s broiler. Arrange the sliced baguette on a baking sheet and toast them under the broiler for 1-2 minutes, until golden brown. Flip the slices over and broil the other side for another 1-2 minutes.

Once the baguette slices are toasted, remove them from the oven. You will use these slices as the base for the cheesy topping.

Step 5: Assemble the Soup

Ladle the hot soup into oven-safe bowls or crocks. Place the toasted baguette slices on top of the soup in each bowl, ensuring they fit snugly. Sprinkle the shredded Gruyère cheese generously over the top of the bread.

Step 6: Broil the Soup

Carefully place the bowls under the broiler for 3-5 minutes or until the cheese is bubbly and golden brown. Be sure to keep an eye on it to avoid burning the cheese.

Step 7: Serve and Garnish

Remove the bowls from the oven and let them cool for a few minutes. Garnish with chopped parsley and chives for a burst of freshness and color. Serve your easy French onion soup immediately while the cheese is melty and the soup is piping hot.

Tips for Making the Best French Onion Soup

• Caramelizing the onions: This step is essential for developing the rich flavor of the soup. Don’t rush it – take your time and let the onions cook slowly to achieve the perfect caramelization.
• Quality beef broth: The broth is the base of this soup, so use a high-quality beef broth for the best results. You can even use homemade broth for an extra depth of flavor.
• Add a dash of balsamic vinegar: For a bit of acidity and sweetness, try adding a teaspoon of balsamic vinegar to the soup before serving.
• Make it ahead: French onion soup can be made ahead and stored in the refrigerator for up to 3 days. Reheat the soup and add fresh toasted baguette and cheese before broiling when ready to serve.
