What You’ll Need

1. Costco French Onion Soup – Purchase a pack of Costco French Onion Soup that suits the number of servings you desire.
2. Onions – You’ll need a few medium-sized onions to bring out the classic sweetness in the soup.
3. Beef Broth – A rich and flavorful beef broth will form the base of your soup. Opt for a high-quality one to enhance the taste.
4. Butter – To add a delicious richness to the onions, be sure to have some unsalted butter on hand.
5. Bread – Traditional French Onion Soup is typically served with a toasted baguette. Choose your favorite crusty bread for this.
6. Gruyère or Swiss Cheese – The cheesy topping is what makes this soup truly irresistible.
7. Salt and Pepper – Seasonings are essential to bring out the flavors in your soup. Have some salt and pepper ready.

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C).
2. Begin by thinly slicing the onions. You can use a kitchen knife or a mandoline slicer for precise and even cuts.
3. In a large pot, melt the butter over medium heat. Add the sliced onions and cook until they become caramelized and golden brown. This process may take around 30 minutes, so be patient and stir occasionally to prevent burning.
4. Once the onions are caramelized, pour in the beef broth. Stir well and let the soup simmer for about 10 minutes, allowing the flavors to meld together.
5. While the soup is simmering, slice your bread into thick pieces and place them on a baking sheet. Toast them in the preheated oven for a few minutes until they develop a light golden color.
6. Remove the soup from the heat and season with salt and pepper to taste.
7. Ladle the soup into oven-safe bowls or crocks, leaving some space at the top for the cheese.
8. Top each bowl of soup with a slice or two of the toasted bread. Then generously sprinkle shredded Gruyère or Swiss cheese over the bread, making sure to cover the edges to prevent burning.
9. Place the bowls on a baking sheet and carefully transfer them to the oven. Broil on high for a few minutes, until the cheese is melted, bubbly, and lightly browned.
10. Remove from the oven, let them cool for a minute, and serve hot, savoring the irresistible aroma.
