Kitchen Equipment Needed

  • Large pot or Dutch oven
  • Whisk
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Ladle
  • Oven-safe bowls for broiling cheese

Ingredients

  • 4 medium yellow onions, thinly sliced
  • 2 tbsp unsalted butter
  • 2 tbsp all-purpose flour
  • 3 cups chicken broth (or vegetable broth for a vegetarian option)
  • 1 cup water
  • 1 cup heavy cream
  • 1 cup shredded cheddar cheese
  • 1 tsp salt (adjust to taste)
  • ½ tsp black pepper
  • ½ tsp garlic powder
  • 1 tsp Worcestershire sauce (optional)
  • ½ cup shredded mozzarella or Gruyère cheese (for topping)
  • Fresh parsley for garnish (optional)

Instructions

1. Caramelize the Onions

Melt butter in a large pot or Dutch oven over medium heat. Add the sliced onions and cook, stirring occasionally, until soft and golden brown, about 15–20 minutes. Be careful not to burn them—caramelization is key for depth of flavor.

2. Make the Roux

Sprinkle the flour over the onions and stir constantly for 2–3 minutes to form a roux. This will thicken the soup and give it a smooth texture.

3. Add Broth and Cream

Gradually whisk in the chicken broth and water until smooth. Stir in the heavy cream and bring the mixture to a gentle simmer, stirring occasionally.

4. Season the Soup

Add salt, black pepper, garlic powder, and Worcestershire sauce if using. Simmer on low heat for 10–15 minutes to let the flavors meld.

5. Incorporate Cheddar Cheese

Stir in the shredded cheddar cheese, making sure it melts completely for a rich, creamy consistency.

6. Broil the Toppings

Preheat your broiler. Ladle the soup into oven-safe bowls, sprinkle with mozzarella or Gruyère cheese, and place under the broiler until the cheese is bubbly and golden brown.

7. Garnish and Serve

Optional: sprinkle with fresh parsley. Serve hot with crusty bread for dipping and enjoy the comforting flavors of this cheesy, caramelized onion soup.
