The History of French Onion Soup:


Before we dive into the recipe, let’s take a moment to appreciate the history of this delectable dish. French Onion Soup, known as “Soupe à l’Oignon” in its native tongue, has a heritage that stretches back to ancient times. Onions, with their abundant and affordable nature, have been a dietary staple for millennia. In fact, the concept of cooking onions in a broth can be traced as far back as Roman times.


However, the version of French Onion Soup that we know and love today has its roots in 18th-century France. It was during this period that the soup truly came into its own, gaining popularity as a staple in Parisian bistros. The combination of slow-cooked onions, hearty beef broth, and the gratinéed cheese topping became synonymous with French comfort food.


The Key Ingredients

Before we get into the cooking process, let’s gather our essential ingredients:


  • 2 cups thinly sliced Yellow Sweet Onions
  • 2 tablespoons Butter
  • 1 can (15-ounce) Chicken Broth
  • 1/4 teaspoon Salt
  • 1/4 teaspoon freshly ground Black Pepper
  • 2 Chicken Bouillon Cubes
  • 1/4 cup compressed Velveeta Cheese (either cubed or shredded)
  • 1 1/2 to 1 3/4 cups Thick White Sauce (recipe below)
  • Shredded Cheddar Cheese for garnish


White Sauce Ingredients:


  • 3 tablespoons Butter
  • 3 tablespoons Flour
  • 1/4 teaspoon Salt
  • 1 1/2 cups Whole Milk




Begin by melting 3 tablespoons of butter in a 2-quart saucepan. Add the sliced onions and sauté on a medium heat until they turn soft and translucent; avoid browning.

Introduce the chicken broth, bouillon cubes, salt, and pepper to the pan. Stir until everything is heated thoroughly.

Gradually mix in the white sauce and Velveeta cheese. Continue simmering on medium-low heat, stirring constantly until the cheese melts and the ingredients combine smoothly.

Reduce the heat to low and let the soup simmer for another 30-45 minutes.

Serve the soup hot, garnished with shredded cheddar cheese. Pair it with slices of warm dark Russian Bread for an added treat.

White Sauce Instructions:

Melt the butter in a 1-quart saucepan. Stir in the flour, cooking on medium heat until the mixture thickens and separates from the pan’s sides.

Gradually pour in the milk, stirring constantly to ensure a smooth mixture. Season with salt.

Keep stirring the mixture until it reaches a thick pudding-like consistency. Once done, remove from heat and set aside until you prepare the soup.



Pro Tips for success :


Caramelizing Onions: The secret to the soup’s depth of flavor lies in perfectly caramelized onions. Cook them low and slow, stirring occasionally for at least 30-40 minutes until they turn a deep golden brown. The sugar helps speed up the caramelization process.


Choosing Cheese: Gruyère cheese is the classic choice for French Onion Soup due to its nutty, melty goodness. However, you can experiment with other cheeses like Swiss or Mozzarella if you prefer.


Broth Matters: Use high-quality beef broth or, even better, make your own by simmering beef bones, onions, carrots, celery, and herbs for a few hours.


Wine Adds Complexity: While optional, adding dry white wine to deglaze the pan after caramelizing the onions enhances the soup’s complexity and depth of flavor.
