Costco Cuisine Adventures French Onion Soup Review

Costco’s French Onion Soup isn’t super flavorful, but it’s convenient and enjoyable!

Today I’m reviewing the Cuisine Adventures French Onion Soup. I was actually given this French onion soup by my parents a few years ago to try. They purchased it from Costco and ranted and raved about how good it is.

Other soups from Costco are the Costco Johnny’s Potato Cheddar Soup Mix, Costco Kirkland Signature Cheddar Broccoli Soup, Costco Ajinomoto Tokyo Style Shoyu Ramen with Chicken, Costco Kirkland Signature Chicken Tortilla Soup and the Costco Authentic Asian Hand Wrapped Shrimp Wonton Soup.

You can find the soup in the freezer section at Costco. The item number is 301883.

So yummy!


The first thing you notice is that the soup is loaded with cheese, onion and pieces of bread! I love how crispy and golden brown the cheese gets on top from baking the soup in the oven. Each serving of soup is fairly small, but it’s a very hearty soup.

The flavors are mild, but pleasant. You notice the different textures of the cheese, onion and bread as much or more than the flavors. The cheese is nice and chewy and the onions add a bit of crunch (though not a lot as they’re well cooked).

Baked to perfection!

I can’t imagine too many people not liking this soup. It’s a mild yet extremely satisfying comfort food that’s perfect for fall and winter. I think it works best as an appetizer, but I’m sure some people out there would love it as a main course!

The Costco Cuisine Adventures French Onion Soup costs $12.49 Canadian for six soups. Keep in mind you’re probably paying a bit for the fancy vacuum seal packaging.

I feel like French Onion soup is something that’s rare to find in a grocery store and also there’s a high probability it won’t taste very good. I enjoy the taste of this soup therefore I would love to purchase this when on sale.

Each soup in the box comes separately vacuum-sealed in plastic and frozen in a cylindrical shape. This is convenient for a single person who just wants to make one soup for themselves. To heat these in the oven, I used special bowls that my mom gave me that are oven-safe and have a large handle on them.

If you really love French Onion soup it might be wise to invest in some nice soup bowls. The soups are frozen with the cheese on top so as the soup heats the cheese stays on top of the liquid and remains crispy. It’s a pretty convenient product because all you need to do is heat and serve it.

I recommend cooking the soup in the oven as I feel like the cheese gets brown and crispy that way. All this requires is putting your soup in an oven safe bowl, turning the oven on and sticking them in the oven for 45 minutes. I always follow the instructions for the recommended oven method that takes longer, so I’m not sure how well the quick method that uses the microwave and the oven works.

  1. It’s finally back in season and I grabbed some and I’ll agree

    Not *super* flavorful but nothing a bit of salt and Worcestershire sauce won’t fix – my one tripping point is that it takes about half an hour to heat using the “fast” method so single bowls aren’t super efficient.

    But as a treat it’s quite nice.

  2. I simply love this soup: I lost weight, lowered my sugar level and cholesterol, tastes great! I am hooked on it. I wish we could get it all year round.

  3. This soup is awesome! I miss it! When will it be coming again to Sun Prairie,WI or Middleton,WI Costcos? Please let me know that it will be soon.

  4. Its a Saturday, I never go to Costco on a weekend, but did today for this soup and zero stock. What is going on Costco?
