Knowing how to freeze spinach for smoothies can save you time and money. Adding leafy greens is a quick and easy way to super-charge your smoothie’s nutrition. Unfortunately, leaves don’t stay fresh for too long which means they often go bad and get thrown away.


In this article – learn how to freeze spinach and kale for smoothies so you can maximise their nutritional value…


Both spinach and kale can begin to wilt after just a few days. As the leaves lose their freshness, their nutrient content can decrease too. The older the produce becomes, the fewer vitamins and minerals it contains.


So, here are our tried and tested tips on freezing spinach for smoothies (which you can totally use for kale or any other leafy greens). They’ll help you keep them fresh for as long as possible so that you maximise nutrient content and don’t have to throw any away.


How Do You Freeze Spinach For Smoothies?

Here are five simple steps to preparing and freezing spinach or kale for your green smoothies


  1. Remove any bad leaves
  2. Use a dry paper towel
  3. Remove as much air as possible
  4. Allow air to circulate around containers
  5. Or use ice-cube trays


Let’s look at each of these steps in a little more detail…


#1. Remove any bad leaves

As the leaves wilt, they release a gas that triggers other leaves to do the same. Just one squishy leaf can speed up the wilting process of an entire packet. Removing any offending leaves at the start will extend the overall freshness by a few days.

Place a dry paper towel into the bag or container. This will absorb extra moisture that can cause spoiling.


If after a few days, the paper towel is wet, then swap it for a fresh, dry one. According to The Kitchn, a container beats a bag for keeping leafy greens fresh, but both will last at least one week.


#3. Remove as much air as possible

Next, you’ll need to remove as much air as possible from inside the storage container.


If using Ziploc bags, then flatten them completely to remove excess air before sealing. If using mason jars or Tupperware containers, then pack the leaves tightly, so there’s no space for excess air.


#4. Allow air to circulate around containers

Spinach and kale freeze well, so it’s a great way to extend their life beyond the refrigerator. Just make sure there is plenty of air circulation around the outside of the containers, to ensure the leaves freeze as quickly as possible.


#5. Or use ice-cube trays

In our humble opinion, this is the best way to freeze spinach for smoothies. Use ice-cube trays to freeze individual portions of leafy greens. Then you can pop a cube in the fridge to defrost overnight, so it’s easy to blend into your morning smoothie.


If you have a high-powered blender, then it’ll have no problems liquefying a frozen cube, so you can add it directly without defrosting. This video shows you how…
