Step-by-Step Recipe for French Onion Soup

French Onion Soup

Preparing the Onions

To begin making French Onion Soup, follow these steps to prepare the onions:

  • Start by peeling and thinly slicing a generous amount of yellow onions. Aim for about 4 to 5 medium-sized onions.
  • In a large soup pot or Dutch oven, melt 4 tablespoons of unsalted butter over medium heat.
  • Add the sliced onions to the pot and stir well to coat them in the melted butter.
  • Reduce the heat to low and let the onions cook slowly for about 30 to 40 minutes, stirring occasionally. This slow cooking process will allow the onions to caramelize and develop their sweet flavors.

Cooking the Onions

Continue with the next steps to cook the onions for the French Onion Soup:

  • Increase the heat to medium-high and cook the onions for an additional 10 to 15 minutes, stirring frequently. This will help to deepen the caramelization and add more flavor to the soup.
  • If the onions start to stick to the bottom of the pot, you can add a splash of water or broth to deglaze and scrape up the browned bits. This will enhance the taste of the soup.

Adding the Broth and Seasonings

Follow these steps to add the broth and seasonings to the French Onion Soup:

  • Once the onions are deeply caramelized, pour in 6 cups of beef broth. You can use store-bought beef broth or make your own if desired.
  • Add 1/2 cup of red or white wine to the pot. The wine will add a subtle tang and enhance the flavors of the soup.
  • Season the soup with salt and pepper to taste. You can also add herbs such as thyme or bay leaves for additional flavor.
  • Bring the soup to a boil, then reduce the heat to low and let it simmer for about 20 to 30 minutes. This will allow the flavors to meld together.

Toasting the Bread and Melting the Cheese

Complete the final steps to prepare the bread and cheese for the French Onion Soup:

  • While the soup is simmering, preheat your oven’s broiler.
  • Slice a baguette into thick rounds and place them on a baking sheet.
  • Toast the bread slices under the broiler until they turn golden brown and crispy.
  • Remove the toasted bread from the oven and sprinkle grated Gruyère cheese generously on top of each slice.
  • Return the baking sheet to the broiler and let the cheese melt and bubble until it becomes golden and slightly browned.

Once the bread slices are ready, ladle the hot French Onion Soup into bowls and carefully place a cheese-covered bread slice on top of each serving. The heat from the soup will melt the cheese even more, creating a delightful and cheesy topping for the soup.

Serving and Presentation of French Onion Soup

French Onion Soup is traditionally served in individual oven-safe bowls. The soup should be piping hot and the cheese on top of the bread should be golden and bubbly. When serving, make sure to place a heat-resistant mat or coaster under each bowl, as they will be hot to the touch.

For an elegant presentation, you can garnish the soup with a sprig of fresh thyme or a sprinkle of chopped parsley. Serve the soup alongside extra toasted bread slices and a side salad for a complete meal. If you love tomato soup then you must know how to make tomato soup.
