This is the most recommended way of freezing kale, and it is also easier on your digestive system. 

Materials

Tools

  • Paper Towel

Instructions

    1. Clean and Prep: Thoroughly wash the kale, getting rid of any wilted leaves or bugs. Then prep the kale based on your preference.

      If you wish to put them in some stir-fry, it would be best to chop it up beforehand. If you don't want the stem to bother you in the smoothies, you can remove it as well.

    2. Blanch: Put the kale in a pot of boiling water for a minute. Then transfer it into an ice bath to stop any further cooking.

    3. Dry the Kale: Remove all traces of moisture from the kale by drying it with a paper towel. The drier it is, the better it will be when frozen.

    4. Pack and Seal: Pack the kale into a Ziploc bag and seal them in. Try to squeeze out as much air as you can before sealing.

    5. Label and Freeze: Add a label on the bag with the best before date, and you are good to go.

Flash Freeze

Leave the tray of kale in the freezer for a couple of hours or overnight and let it freeze solid.

Here is a tutorial by “Organize Yourself Skinny” on YouTube with this and several other kale freezing tips –

How Long Can You Freeze Kale? 

Kale can last in the freezer for 6 to 12 months. If it has been blanched beforehand it will last for longer than kale that wasn’t blanched. The raw kale lasts in the freezer for only a couple of months. 

But in any case, it is best advised to consume the kale sooner rather than later. Though it can last for long in the freezer and may be safe to eat, its quality and texture deteriorate over time.

How to Store Frozen Kale? 

You can store frozen kale in Ziploc bags or freezer-safe air-tight containers. The key is to make sure that they are dry and protected from being exposed to air or freezer burns. 

But Ziploc bags are your best bet if you don’t have much freezer space and have a big batch of kale to freeze.

Whether it is blanched kale or frozen kale scoops, the Ziploc bags offer more compact storage than freezer-safe containers. 

How to Defrost Kale? 

Although you needn’t defrost frozen kale to use it, you can thaw it by leaving the bag of the portion you need in a bowl of cold water for a while. 

But keep in mind that the kale can get slimy and soft once it thaws and might not be great to cut or work with.

So, it is best to cut them up beforehand and cook them right out of the freezer. 

You can directly add frozen kale into your smoothies or any other recipe of your choice. If it has been frozen for long, it is best to cook them. 

Can You Refreeze Kale? 

Although you can refreeze kale, it is best advised not to. If you do refreeze it, you should only do it once, and the kale should not have been left out for too long. 

The kale can get slimy and change in taste and texture once it thaws. Repeated freezing will only worsen this condition and also increase the chances of bacterial growth. 

Does Kale Freeze Well? 

Yes, kale freezes well, and it is a great way to extend its shelf life and a perfect way to portion it for smoothies or other recipes. Blanched kale freezes best and lasts for longer. 

But kale freezes best for a couple of months and, irrespective of its freezer-life, will deteriorate in quality and taste, the longer it stays in the freezer. 

FAQs

Can you freeze kale chips? 

Yes, you can freeze kale chips, but they will lose their crunch and crispiness. So, it is not recommended.

You can lay them out on a baking sheet lined with parchment paper and flash freeze them before freezing them for the long term.

Can you freeze kale pesto? 

Yes, you can freeze kale pesto, and it can last in the freezer for up to 3 months. You can flash freeze them in ice cube trays before freezing them in Ziploc bags.

Or you could freeze them in air-tight freezer-safe containers.

I hope this article helped you freeze and store kale for the long term.
