How to Freeze Potato and Leek Soup

As soup is a liquid, it can be really easy to freeze but using potatoes in a soup can complicate things somewhat.

It is important to only freeze cooked soup, as freezing raw potatoes could cause them to discolour and change texture, which will, in turn, affect your soup.

By following the below steps, you can ensure the perfect frozen potato leek soup every time. 

  1. Make Soup
    Follow your favourite potato leek soup recipe, except do NOT add the heavy cream.
  2. Leave to Cool
    Allow the soup to cool to at least room temperature. To do this, you may either leave it on the counter for up to 2 hours, or place it in the refrigerator for 2 hours.
  3. Portion & Place In an Air tight Container
    Portion out the soup into freezer-safe containers. If you freeze it all in one container, it is going to be very difficult to portion out when it comes to thawing. 
  4. Freeze
    Once fully cooled, label and date your containers, and then store them in the freezer away from the frost zone.

3 Tips for Freezing Potato and Leek Soup

Now you know how to freeze it, we’ve got our Top 3 Tips, which we strongly recommend following to have the best results:

Freeze Quickly
As a guide, you should ensure you put your soup in the fridge or freezer within two hours of preparing it, as this won’t give bacteria any time to grow.

Use Appropriate Containers
The best freezer containers for soups are glass containers so that the soup doesn’t take on a taste from other items in the freezer. Ziplock bags can also work really well for soup if you are tight on space, just be sure to squeeze most of the air out to prevent the bag from exploding in the freezer. 

Add Dairy Later
Unfortunately, cream and milk will split somewhat in the freezer resulting in a grainy or gritty soup. If you’re used to having a silky smooth soup then avoid dairy products and add them in after thawing, instead.

How Long Can You Freeze Potato and Leek Soup?

You can freeze the soup for roughly 6 months. The sooner you can use it the better as potatoes can start to degrade in the freezer and the longer this happens, the higher the likelihood that your soup could turn grainy or mushy when defrosted. 

How Do You Defrost Potato and Leek Soup?

The easiest way to defrost and thaw potato leek soup is to remove one container from the freezer and place it in the fridge overnight.

However, if you need the soup defrosting quicker, you can place the container or ziplock bag into a bowl of warm water.

You can even use the microwave – simply place the container into the microwave and cook on full power for 2-3 minutes. You’d only really want to microwave the soup if it is smooth and not chunky, as if it were the latter, the soup would have a tendency to go mushy. 

Can You Refreeze Potato and Leek Soup?

You should not refreeze soup that has already been thawed and reheated. Hence, we recommend you portion into individual containers so that you only need to defrost the portions you are going to use at any given time. 

Does Potato and Leek Soup Freeze Well?

Potato leek soup does freeze well and is a great meal to keep in the freezer for last-minute meals.

It isn’t necessarily the easiest soup to freeze, this is mostly due to the water content in the vegetables, but if you follow the steps above, you’ll be able to freeze soup with a great flavour and great texture.
