How to Freeze Spinach (or any other leafy green)

Leafy greens have some pretty amazing superpowers, nutritionally speaking, but they don’t stay fresh for long. I’m going to show you how to freeze spinach (or any other leafy green), and 10x it’s shelf life!

Now, for some context…

I mostly consume leafy greens in smoothies. If you’ve never had a “green smoothie,” then this is the absolute first recipe you should try (click here).

This spinach freezing hack may not be for everyone, but if you’re planning on blending your greens then I’ve got two words for you: spinach cubes.

That’s right! Stocking the freezer full of spinach cubes is a great way to get quick and creative with smoothie recipes (while keeping the greens from going bad). That’s what I call a win-win!

I don’t typically recommend adding ice to your smoothies because it dulls your blender blades and also causes the motor to work extra hard, but these cube recipes are the exception to the rule.

how to freeze spinach cubes

How to Freeze Spinach:

Following these simple steps can literally make your spinach (and other leafy greens) last 10x longer. Try to use as many fresh leafy greens as possible, but if they’re getting close to the expiration date then make these cubes:

  1. Place 2 cups of leafy greens (about two handfuls) in a blender with 1/2 cup liquid (preferably water, but a touch of lemon juice can help).
  2. Blend greens and liquid until it reaches a juice-like consistency.
  3. Pour contents into an ice cube tray, and freeze.
  4. Once frozen, you can remove the cubes from the tray and store them in a separate container in your freezer.

That’s all there is to it! You can follow these same steps for kale, chard, romaine, cabbage, and even herbs.

    I just buy organic prewashed kale and freeze the whole bag. I take out a handful when I need it for my smoothie.

  2. Theresa Jackson says:

    How many cubes would you blend in your recipes?

    • SGS Rawkstar Carissa says:

      Hey Theresa,

      It depends on how much spinach you had to freeze. If you blended a half cup of spinach and put the entire thing in one tray, then I would put the whole tray in your blender 🙂

  3. Christina says:

    What a great way to prevent waste of fresh leafy greens that sometimes go bad before they are all used up.
    Thanks for the tip!!

  4. beth says:

    When my leafy greens are at the end of their fridge life I pack them into a ziploc in 1 cup increments and freeze them. ARe your cubes better (healthwise)?

    • SGS Rawkstar Carissa says:

      Hey Beth,

      That is a great way to freeze your greens as well. We just wanted to share another way you can use up your extra greens that you might have laying around.

  5. Carol Simpson says:

    I just put the bag of greens in my freezer. It does take up more room than cubes would, but then the recipe is just the same, and you are not blending ice cubes, which can be bad for your blender. I also cut up and freeze anything that is just starting to get overripe, or I don’t want to use right then, to use in smoothies later, like cubed beets, cut up carrots, pears, apples, peaches, mangos, etc. I buy boxes of bananas on sale, peel them, break in half, and arrange flat in gallon Ziplocs. They do discolor over time, but are fine for smoothies.

    Another hack that I use, too (for SGS meals!) is use my ice trays to freeze tablespoons of tomato paste. When a recipe calls for a few tablespoons of paste, less than the whole can, I measure the leftovers into ice trays in 1 T. increments. Freeze and pop into a Ziploc bag to save for other recipes. Recipes calling for tomato paste are usually hot anyway, and it only take a minute for them to melt into whatever you are using them for.

    • SGS Rawkstar Carissa says:

      Hey Carol,

      I love your freezing method! Thank you so much for sharing that 🙂

      These leafy green ice cubs are not bad for your blender because they are not as dense as just water is in a solid ice cube. This is just another option that could help with salvaging your extra greens you might have left over after you have blended your batch.

    That is how I do all my greens also my herbs

  7. Lola says:

    How many cubes would you put in a smoothie???

    • SGS Rawkstar Carissa says:

      Hey Lola,

      When you blend 2 cups greens and 1/2 cup liquid that should fill up a whole tray. So however much that fills up is what you will add to your smoothie. If your tray has 12 cubes then you will add those 12 to your smoothie.

      Hope that helps!

  8. Tudy says:

    Why can’t you just freeze spinach as is and grab them when you are ready to blend?

    • SGS Rawkstar Carissa says:

      Hey Tudy,

      You can totally do that too! This is just another option to freeze your greens. Also, doing it this way you already have your water (or other liquid) in it so you just need to add your fruit and you are ready to go.


  9. Brianna says:

    Totally going to try this! I’m so excited about this. I am constantly throwing away greens because I couldn’t use them fast enough.

  10. Adaiha says:

    This is such a great idea! I like to prep my smoothies ahead of time whenever I can so I throw the spinach in the freezer bag along with the fruit. Definitely trying this for the spinach I have leftover though.
    Thank you for sharing!

    • SGS Rawkstar Carissa says:

      Hey Adaiha,

      It really is a great way to save that extra spinach!! Can’t wait for you to give it a try.

      Cheers!! 🙂

  11. Jade says:

    Quick Question! If a recipe calls for 1 cup of leafy greens, how many green cubes would you use in this instance?
    Love you guys so much!
    Thank you!

    • SGS Rawkstar Carissa says:

      Hey Jade,

      When you blend 2 cups greens and 1/2 cup liquid that should fill up a whole tray. So however much that fills up is what you will add to your smoothie. If your tray has 12 cubes then you will add those 12 to your smoothie.

      Hope that helps! 🙂

  12. Leigh says:

    It says 2 cups of greens and 1/2 liquid. 1/2 of what? 1/2 cup of water? Thanks!

    • SGS Rawkstar Carissa says:

      Hey Leigh,

      Yes it would be water unless you are making your smoothie with a different liquid base, like almond milk or ect.

      Hope that helps!

  13. Theresa OMara says:

    Yes I do sometimes get frustrated by not using my greens fast enough. This is a green saver! Thank you for this tip. Great way to prep ahead!

    • SGS Rawkstar Carissa says:

      Hey Theresa,

      So glad you found this post to be helpful!!

      Cheers to saving those greens!!

  14. DonWeber says:

    While not freezer related, I have purchased a Genius Air Plus Refrigerator Refresher & Deodorizer. It helps keep food in the fridge fresher longer and keeps odors down. It’s like a battery powered box of Arm and Hammer.

    • SGS Rawkstar Carissa says:

      Hey Donweber,

      That is so interesting! I have not heard of that before but will definitely check it out.

      Thank you for sharing that with us 🙂

  15. Pam T says:

    I stuff spinach into 1 cup containers (ziploc style plastic) and freeze. When I have lots I also have filled larger containers (and froze) and just cut out as needed. I then just pop into blender and blend as usual. I also put kale into containers and freeze. I blend from frozen for a smoother finished product.

    • SGS Rawkstar Carissa says:

      Hey Pam,

      That’s a creative way to freeze your greens!

      Thank you for sharing that with us! 🙂

    • Kristen says:

      Hi Pam,

      Thanks for your tip. I prefer not to use ice cube containers ( because they’re plastic). This will work out great for me.

  16. Kathy says:

    Would love to do this, but do not have the freezer space! Instead, I package greens in freezer bags – once I fill the bag, I flatten and roll to get the air out! I can find room for the rolled bags!!! When ready to use, I hit the bag against the counter edge to shatter the greens and then use what I need!

    • SGS Rawkstar Carissa says:

      Hey Kathy,

      That is a pretty rawesome way to freeze your greens too!

      Thanks for sharing =D

    What is in the ice cubes to the right? (Looks like bananas maybe?).
