How to Cook Costco French Onion Soup
Cooking Costco French Onion Soup is straightforward, and there are several methods to choose from depending on your time and equipment. Each method has its unique benefits, so you can select the one that best suits your needs.
Oven Method: Best for Flavor and Presentation
The oven method is the preferred way to cook this soup if you want the best flavor and texture. Preheat your oven to 400°F while unwrapping the frozen soup and placing it in an oven-safe bowl, cheese side up. Bake it for 40 minutes or until the cheese is bubbling and golden brown. This method allows the soup to heat evenly, and the cheese develops a beautifully browned crust that enhances its presentation. If you want to take the flavor up a notch, add a sprinkle of Gruyère cheese or some fresh herbs like thyme before baking. This method may take longer, but the results are worth the wait, offering a restaurant-quality dish in the comfort of your home.
Microwave Method: Quick and Convenient
If you’re short on time, the microwave method is the fastest way to prepare Costco French Onion Soup. Place the frozen soup in a microwave-safe bowl with the cheese side facing up. Heat it on high for 3 minutes, then stir to ensure even melting. Heat for an additional 2 minutes, and the soup is ready to serve. While this method is convenient, it has some drawbacks. The cheese doesn’t achieve the golden-brown crust that you get from baking, and the texture of the croutons and onions may be softer than expected. However, it’s a great option for those needing a quick meal without much effort.
Stovetop Method: A Flavorful Alternative
The stovetop method is another excellent way to prepare this soup, offering a balance between flavor and convenience. Place the unwrapped frozen soup in a small saucepan and heat it over medium heat. Stir occasionally to help the block melt evenly. Once the soup begins to boil, reduce the heat to low and stir more frequently to ensure a smooth texture. In about 15–20 minutes, the soup will be fully melted and heated through, ready to serve. While this method doesn’t create the crispy cheese topping typical of baked French onion soup, it retains the rich flavors of the broth and onions. Garnishing with fresh parsley or a drizzle of olive oil can enhance the dish further.
Air Fryer Method: Modern and Efficient
Using an air fryer is a modern twist on preparing Costco French Onion Soup. This method offers the benefits of faster cooking while achieving a texture similar to the oven method. Place the frozen soup in an oven-safe dish that fits your air fryer. Set the air fryer to 375°F and cook for about 25 minutes, checking periodically to ensure the cheese doesn’t overcook. This method is perfect for those who want the rich flavor and crispy topping of the oven method but with less waiting time.

Creative Serving Ideas and Variations
Pairing Costco French Onion Soup with complementary sides and toppings can transform it into a complete and satisfying meal. Serve it alongside a crusty baguette or a loaf of sourdough bread for dipping into the flavorful broth. For a more balanced meal, add a fresh salad with vinaigrette or roasted vegetables as a side. To elevate the soup itself, consider topping it with additional cheese like Parmesan or Gruyère before cooking, or garnish it with fresh thyme or parsley. If you’re feeling adventurous, use the soup as a base for a casserole or a topping for baked potatoes. Pairing it with dishes like crispy air-fried chicken wings or Tyson chicken patties can make for a hearty and indulgent dinner.
