How to Freeze Spinach

Before you get to preparing and freezing your spinach, the first thing you need to do is make sure it is completely cleaned thoroughly. Submerge it into cold water in a colander, give it a good scrunch to ensure the water gets in to all the cracks, then drain.

  1. Blanch
    Bring a large pot of water to a boil. While waiting for the water, also prepare a bowl of ice water. Once the water is boiling, you need to blanch the spinach. You want to place the spinach in the boiling water for between 90 and 120 seconds. Any longer and you’ll cook it too much. Remove the spinach from the boiling water and place it straight into the ice water.
  2. Drain and Dry
    Now drain the spinach and squeeze it dry.
  3. Portion into Cubes
    Push the blanched spinach into an ice cube tray. This will make it far easier to portion out. Place the ice cube tray into the freezer for 3 to 4 hours to allow your spinach to freezer solid.
  4. Bag Up
    Pop the cubes out of the tray and place them into a freezer bag. When you seal your bag, try to remove as much air from the bag as possible. You can do this by sucking the air out of the bag with a straw.
  5. Final Freeze
    Return the cubes to the freezer, and you’re good to go.

This is a method for freezing we love to use for all leafy greens from kale and cavolo nero to swiss chard and beetroot tops.

The good news is that you don’t need to defrost your spinach beforehand. You can use it straight from the freezer.

Can You Refreeze Spinach?

We would not advise refreezing spinach. You’ll draw a lot of the flavour out, and you’ll often be left with mushy, gloopy spinach when you eventually eat it. 

Instead, try to focus on thawing out a portion at a time to avoid unwanted waste.
