Costco French Onion Soup Instructions

Let's take a look at Cuisine Adventure French onion soup, one of the best frozen French onion soups at Costco. We'll see how to prepare it in the oven, microwave, and air fryer. To the best of my ability, I have tried to cover all the aspects of this product.

Cuisine Adventures French Onion Soup From Costco

Costco french onion soup has all the same ingredients as the traditional french onion soup, which has onion, Swiss cheese, toast, garlic, and some spices. The soup is precooked before freezing to preserve the flavor. In almost any precooked food company, freezing fast is used to keep food fresh for a longer period of time without losing its flavor.

A French cuisine adventure french onion soup package comes with 6 servings, every 10 ounces in size. Costco sells it for about $9.49. But Maybe while you reading this post there is some change in the price.

How Long Do You Cook French Onion Soup From Costco

It states on the package of Costco french onion soup that you should cook frozen soup in the oven for 40 minutes at 400°F (200°C). This is not even close. In my experience and according to many other reviews, Cooking it in the oven at 400°F will take you between 55 minutes and 60 minutes.

The microwave will take about 5 to 7 minutes to heat the Costco french onion soup completely. In the air fryer, you'll need between 30 and 35 minutes at 400 degrees. However, some air fryers will take less time.

Important: All those cooking times are approximate, you can't find the exact time. In that case, you need to heat the french onion soup until the temperature reaches 170°F to 180°F.
