    Does Costco Sell French Onion Soup? Where In Costco Is The French Onion Soup?

    Costco French Onion Soup

    Costco sells Cuisine Adventures French Onion Soup in the frozen foods section of the warehouse. The store sells it seasonally, usually first appearing in September. Each box contains six vacuum-sealed servings of 10 ounces each. 

    We paid $10.99 in 2023. 

    French Onion Soup at Costco Price

    We paid $10.99 for a package of six Cusine Adventures French Onion Soup at Costco in September 2023. This breaks down to $1.83 a serving, an excellent price.

    We checked our local grocery stores and higher-end grocer Whole Foods and couldn’t find a comparable product to check prices. The closest we found was a can of Campbell’s Condensed 

    French Onion Soup for $1.99. 

    French Onion Soup Costco Cooking Instructions

    Costco French Onion Soup In Microwave

    The manufacturer provides three ways to cook. We tried them all, and our favorite was using the oven/microwave. The results were comparable to the oven-only method while taking half the time. The microwave works if you are short on time; just know that the cheese mixes into the soup. It’s ok, but not as good.

    CONVENTIONAL OVEN

    1. Preheat oven to 400°F (200°C).
    2. Place the soup cheese on top in an ovenproof bowl.
    3. Heat for 40 minutes or until the cheese becomes golden brown.

    MICROWAVE OVEN (The Cheese Mixes In)*

    1. Place one soup, cheese side up, in a microwave-safe bowl.
    2. Heat on HIGH for 3 minutes.
    3. Stir and heat for 2 minutes more.

    The directions recommend using a 10-ounce mug with a 4″ diameter opening. When frozen, the brick of soup is bigger than the mug. Not to worry, as it cooks, it melts down but somehow doesn’t make a mess.

    QUICKER OVEN METHOD Using Oven and Microwave

    1. Preheat oven to 400°F (200°C).
    2. Place one soup, cheese on top, in a bowl safe for microwave and conventional oven.
    3. Heat on HIGH for 3 minutes in the microwave oven.
    4. Remove soup from the microwave oven; sprinkle 2 Tbsp of additional shredded Swiss or other firm cheese.
    5. Heat in the oven for 20 minutes or until the cheese becomes golden brown.

    Costco French Onion Soup Review

    To properly review Costco French Onion Soup, we must discuss its convenience, price, and taste. 

    CONVENIENCE:

    Each serving is vacuum-sealed and easy to open, making preparation a breeze. The main downside is how long they take to cook. While the microwave method only takes minutes, the preferred combination oven-microwave process takes 30 plus minutes when you factor in preheating time, which is fine for dinner but is not feasible for lunch. 

    PRICE:

    If we break the $10.99 price down per serving, each cup costs $1.83, which is an excellent deal for what you get. Add some sweet potato fries and a side salad, and you have dinner for less than $3 per person! 

    TASTE:

    We made the soup using every method listed. It was a bit better when making it in the oven, but it took almost an hour! For that amount of time, we wished it tasted closer to homemade. It has some flavor without being overly salty. Although one of the things we love about French Onion Soup is the depth of flavor the carmelized onions add. This product needs that critical element of French onion soup. 

    OVERALL

    We would give the Costco French onion Soup a 6 out of 10 rating. It’s an excellent price. However, the serving size lends itself to a lunch versus a dinner, but it takes too long to be a

    How to Make Costco French Onion Soup Better

    Costco French Onion Soup is okay, but it could be better, especially if you microwave it.  Here are a few ways to add flavor and texture. 

    Croutons — As the soup cooks, the croutons get soggy. You can remedy this by adding plain croutons or pieces of hearty bread. It helps change the texture. 

    More Cheese — Another easy way to amplify flavor is by adding cheese. Swiss, mozzarella, or gruyere would all work. 

    Splash of Hot Sauce —  A few splashes of hot sauce, like Frank’s, add some depth the soup is missing. 

    Toast — Cut a piece of toast and place it on the soup. 

    Crispy Onions — Crispy onions shouldn’t be relegated to green bean casseroles on Thanksgiving. Instead, put a handful in the soup for 

    What To Serve With Costco French Onion Soup

    Costco French Onion Soup With Sweet Potatoes, An Excellent Side Dish

    This soup can quickly become dinner with a simple side. Here are some excellent options.

    Sweet Potato Fries — We love the sweet potato fries from the warehouse. They are easy to prepare and provide great sweetness and crunch.

    Side Salad — Try one of the Costco Salad Kits for an easy-to-assemble veggie side. Asian cashew or Caesar are excellent options with French Onion Soup. 

    French Fries — You can never go wrong with a simple french fry on the side. 

    Ham Sandwich — Not just any sandwich, but a melted ham and Swiss cheese sandwich is a tasty complement to Costco French Onion Soup.

    Turkey Sandwich — If ham’s not your thing, a simple turkey sandwich on rye would be delightful! Swiss cheese is great to use since it’s an ingredient in the soup.
