How To Freeze Spinach For Your Green Smoothie

Keep your leafy greens fresh by freezing them for your smoothies and recipes. Find out how to freeze spinach 3 different ways.

How To Freeze Spinach For Your Green Smoothie

I have recently started to pay more attention to the benefits of organic food as I continue to clean up my diet.  I never used to bother buying organic greens.  

I just used to use normal spinach or kale or store bought frozen spinach.  

I didn’t used to buy much organic produce at all as I reasoned that I would rather use the money to buy more fruit than have to buy less but more expensive organic produce.

However, I’ve changed my mind recently.  I don’t want to have to eat more pesticides than I need and if that means filling up on more carbs rather than fruit I’ll take that option.

As leafy greens are practically all surface area, pesticides heavily cover them and you will end up eating a large amount of these chemicals on from your greens.  

I can actually feel the difference touching the spinach myself.  

Normal spinach feels very waxy and organic spinach feels a lot fresher.  

There isn’t actually much difference in price where I live but the problem is I can’t get hold of it at my local store.  

So that means I have to buy in bulk to last me 1-2 weeks, which means I have to freeze my greens to make them last.

4 Reasons for Freezing Your Greens For Green Smoothies:

There are several reasons why it’s good to freeze your leafy greens for your green smoothies:
 
1) It avoids your greens going bad
2) It keeps the greens fresher
3) It cools down your smoothie
4) It can be quicker to blend

How to freeze spinach (or other leafy greens)

There are 3 ways to freeze your greens.  The only mild organic greens I can get hold of are spinach and kale so I can’t do much rotation of my greens.  I’m hoping to grow more chard in the summer though and I will use romaine lettuce occasionally but I prefer to eat this in my daily salad.  Here are the 3 ways to freeze your greens. You can follow these directions for any leafy greens.  I usually mix my spinach and kale together.

1: Blend raw greens with water and freeze

This is the method I use.  As my greens are pre-blended it means less blending when I come to make my smoothie and they can be easily poured into molds and you can measure exactly how much you are using.  It makes your smoothie lovely and cold too.  I would add the frozen green chunks in at the end of making your smoothie as it will be easier for your blender to blend them. It is pretty simple to make these.

  1. Wash your fresh greens.  You can blend as much as will fit in your blender from a couple of handfuls up to a large amount.  I usually add about 3 bags (600g/ 21 oz) about 6 large handfuls in total until my blender is pretty full. 
  2. Add 1 Cup of water to your blender
  3. Add the first couple of handfuls to your blender and blend for a couple of seconds until the greens have been dispersed into the water.  Continue to add your greens blending briefly until all your greens are added.
  4. Blend all the greens for a minute or so until they are smooth.
  5. Pour the green water into molds.  You can either use muffin trays, mini muffin trays or ice cube trays.  I think mini muffin trays are the perfect size to add to smoothies if you don’t have a high speed blender as the larger muffin trays may not be able to blend as easily.  I more often use the larger muffin trays now as it makes it quicker to pour, remove them and pop a couple into a big batch of smoothie every day.  I also use silicone trays and molds which makes it very easy to get the frozen greens out of them when they are frozen.
  6. If you want to know how many cups you are getting per mold you’ll have to measure how many loosely packed cups you add to your blender then divide that by the number of molds you use.  You will then know how many cups you are putting into your smoothie.
  7. Put your muffin/ ice cube trays in your freezer and freeze until solid.
  8. Remove the frozen greens from the trays.  If they aren’t coming out easily you may need to wait a few minutes for them to slightly defrost.
  9. Add the frozen green chunks back to your freezer in a bag.
  10. Pop a couple of frozen green chunks in your blender after you’ve added all your other ingredients to your blender for your smoothie.  You can also use these chunks in soups or stews but not good for any recipes that you need a bit of texture for as they are blended up smoothly.

NOTE: If your blender can’t cope with frozen ingredients, just leave these to thaw before adding them to your blender.  It will make your smoothie much smoother and easier to blend.    The smaller the green smoothie cubes are, the easier they are to blend.

 2: Freeze raw green leaves

This method is easier than the above method but I like blending my greens as it compresses the greens down and I don’t have to take up much space in my freezer.  This method is so quick and easy.

  1. Wash your greens
  2. Add them to freezer bags, pressing them down and squeezing all the air out of them.
  3. Tie the bags up and freeze them .
  4. When ready to use you can break chunks of greens from your bag for use in either your smoothies or cooking.

3: Freeze Blanched green leaves

Some people prefer to blanch or lightly steam their greens before consumption.  There is concern that if you eat too much spinach you may consume too many oxylates.  Some people are sensitive to oxylates and if you find you can’t tolerate spinach then I suggest you do some more research into this.  This article is a good starting point.  You may prefer to blanch your greens to reduce the level of oxylates, retain the colour of the spinach brings out the flavour and reduces them down.  This will also reduce the amount of nutrients in the greens which is why I don’t do it.

  1. Bring a large pan of water to the boil
  2. Wash your greens
  3. Add them to the boiling water for a couple of seconds.
  4. Remove, add to cold water to stop them cooking, drain and spin or squeeze the water out.
  5. Add them to freezer bags, pressing them down and squeezing all the air out of them.
  6. Tie the bags up and freeze them .
  7. When ready to use you can break chunks of greens from your bag for use in either your smoothies or cooking.

Hi Katherine,

I just wanted to tell you I completed the 7 day detox and I feel so great.

I have lost 6lbs, do not feel like I need more my morning coffee, the flushing of my facial skin from rosacea has dramatically reduced and I am so excited to wake up each morning and make a green thickie for breakfast!!

I am a stay at-home, homeschooling momma of 3 littles and at times so busy I would forget to feed myself!

I would go most of the day without eating and then snack on random things.

I gained 60 pounds the last 6 years during pregnancy.

I have lost 30lbs but recently plateaued and have felt so frustrated.

I’ve tried everything from paleo and keto to the point where I didn’t know what to eat or how much and felt like even eating fruit was bad for me which thankfully it’s not!

What a game changer for me. Thank you for sharing a simple but effective program.

I’m so excited to continue another week with this plan! Thankful Stephanie

  2. I just freeze some spinach in the bag I bought it in, if I don’t finish it within a few days. I do the same with celery, although I haven’t eaten the frozen celery my dogs LOVE it!! I keep a bag in the freezer with all sorts of veggies ends and peels etc. that they can eat. I even save the veggies that are cooked after making a veggie stock and freeze them for my dogs! (They are VERY healthy almost vegetarian dogs) Every once in a while I give them some meat with bones. My dogs are highly alergic to packaged dog foods!

  4. Thank you for mentioning the oxalate’s!! Omgosh~ I ended up with a nightmarishly -Horrendous medical problem that lasted for 7 plus years, because of going crazy with the new juicer. TOO MUCH oxalates -deep colored veggies particularly loaded with em, CAN SERIOUSLY hurt us. PLEASE…be careful. Loved loved your ice cube tip!! You can put them in soups too…i’m not at all enamored of kale, but doing it this way,I can easily moderate how much oxalates I’m getting, plus don’t even know they’re there! yayy!

    • You may not care for kale, but I actually love it more than spinach ONLY if it’s cooked correctly. If it’s not, it’s completely disgusting to me.

      The trick is to blanch it. Boil the crap out of it, drain it, and then put it in heavily iced water. I’ve even heard of someone doing that and then going back and boiling it again with spices (you can’t go wrong with some garlic, salt, pepper, and a little bit of lemon zest)

  5. Thank you for the information. I have been wondering about freezing my greens. I go to the supermarket once a week and I always find that by the end of the week my greens aren’t looking too good. They aren’t spoiled, but aren’t as crisp. Now I can freeze them at their freshest. When using the first method to freeze your greens (muffin cups, muffin tray, or ice cube tray), how many of each do you put in your smoothies?

    Reply

    • I usually put about a cup of frozen greens in my smoothies (one recipe that makes 2 servings) but you can just add it depending on your own preferences. I just add as much as I can without it overpowering everything else. The more greens the healthier it is!

  6. I started freezing my greens as well. I cut everything into pieces & prepare a week or more of smoothies. I freeze all the ingredients together in a container or a bag because sometimes I don’t have the time to wash & cut the greens every morning. For this reason, I prepare everything in advance. Usually, I freeze together (pineapple, celery, kale, spinach, parsley, & cilantro)and if I have a lot of kale & celery, I cut them into pieces & put them in a freezing bag so I can use them later. Every morning I just get a container or a bag from my freezer & do a smoothies for my husband & me. Thank you for your idea…I will try yours as well.

  7. Isn’t healthier to freeze the greens whole rather than blending them first? Doesn’t that make them lose more nutrients? I want to start freezing my greens since they always spoil but I want to keep all the vitamins.

  9. after you blend and freeze the spinach, when you thaw it do you then consider the serving to be loosely packed or tightly packed?

    Reply

  10. I didn’t blanch my kale and spinach, but I washed and bagged them and kept them frozen for four months. I plan to just make smoothies out of them now. Are they still safe to consume after four months? Are they still as nutritious?

    Reply

    • Hi Irene, they will still be safe to consume and you’ll smell if it is no longer perfect. The nutrients might have depleted a little bit but they will still be healthier than processed foods.

  11. I’ve tried freezing whole leaves before. I found that when I blended them they were very frothy & I didn’t like it. Has anyone noticed the same when using the first, fully blended before freezing, method?

    Reply

  12. Where can I find information on the effects of freezing greens, or other vegetables and fruits for that matter?

    I’m interested in the effects of nutrient loss over time.
