Leafy greens have some pretty amazing superpowers, nutritionally speaking, yet they don’t stay fresh for long. I’m going to show you two different methods for freezing spinach (or any other leafy green) to give your greens 10x the shelf life! Never let that beautiful bag of fresh spinach go to waste again.
Now I know we’ve all been there. You buy that big beautiful bag of greens, lovingly place it in your fridge and vow to eat it for daily lunches and smoothies. Two weeks later you’re digging through that fridge only to find a bag of gross, wilted mush that once resembled spinach. This was definitely me when I first started drinking green smoothies. I knew I needed a better way to store my leafy greens. These two quick methods do exactly that!

How to Freeze Spinach
Following these simple steps can literally make your spinach (and other leafy greens) last 10x longer. Pick the method you like best and go crazy!
Freezing Greens Method #1: Cubes
Try to use as many fresh leafy greens as possible, yet if they’re getting close to the expiration date then make these cubes.
- Blend 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). It’s done when it reaches a juice-like consistency. The goal is no leafy chunks!
- Pour contents into an ice cube tray, then freeze. Make sure the tray is level in the freezer.
- Store the frozen cubes in a freezer-safe container. I use gallon silicone ziplock bags for zero freezer burn.
You can follow these same steps for kale, chard, romaine, cabbage, and even herbs. I don’t typically recommend adding ice to your smoothies because it dulls your blender blades, as well as causes the motor to work extra hard, yet this cube recipe is the exception to the rule.
Freezing Greens Method #2: Storage Bags
For this method, gather the following items: fresh spinach, dish towels, paper towels, freezer-safe bags or containers and a sharpie.
- Prepare spinach by washing and drying. Pack the spinach into freezer-safe bags or containers. You can pack the spinach tightly. Label bag or container with date. If a precise amount (such as for a recipe) for the spinach is needed, make sure to add that to the label as well.
- Place bags or containers in the freezer, allowing for air circulation for proper freezing. If using spinach within a few weeks or months, a standard freezer is sufficient. For longer freezing times, a deep freezer is recommended as it will keep the frozen food at a lower temperature, prolonging its quality. Note that for deep freezing or longer freezer storage times, it may be prudent to double bag the spinach in order to prevent freezer burn.
As the spinach leaves freeze, they will lose a lot of volume due to ice crystals breaking down the cell walls. (For this reason, frozen spinach is also easier to blend when making green smoothies from a freezer pack.) And done! No need to waste spinach any longer.
FAQs
Yes! No need to cook fresh spinach before freezing it. Fresh spinach is also more nutrient-dense, so freezing fresh spinach holds in more nutrients than freezing cooked spinach.
Nope! No need to blanch before freezing. Fresh spinach easily blends in water, and since it is getting blended into a smoothie at some point, then that alone negates any need to blanch.
You sure can. The bagged spinach from Costco freezes just as well as the fresh spinach from the roadside stand. Just give the bag a sniff test before starting to blend, to make sure it’s still fresh.
Why Should I Freeze Spinach?
Unless you buy spinach by the cup-full every day for your green smoothie (or pick from your garden), you probably buy it in bunches. Or like me, in Costco-sized bags. It starts out crisp and fresh, yet after only a few days, starts to wilt and smell funky. I used to throw out half bags of spinach all the time because I couldn’t get through it fast enough.
I learned how to freeze fresh spinach because I was sick of wasting money and time on something that didn’t last. Concerned about the loss of nutrition from freezing spinach? Read on.
Fresh vs Frozen Spinach
I often get emails asking about how to use frozen fruit and veggies while still getting the most in the way of nutrients. The truth is, frozen produce is often less expensive than fresh. It’s also frozen at peak freshness, making it even fresher and more nutrient-dense than some of the fresh produce at the grocery store.
My best advice is to buy produce fresh in its season, then freeze it to retain almost all those precious nutrients. Even if you grow your own leafy greens, you can prolong the shelf life by learning how to freeze them properly.

How to Freeze Spinach Cubes
Ingredients
- 4 cups fresh spinach 10-oz bag
- 1 cup water
Instructions
- Add ingredients to the jar of a blender in the order listed. Pulse a few times, then turn onto high and blend until smooth. If needed, add a little more water for easier blending.
- Scrape down sides of blender and look to see how much liquid there is. Add enough water to fill to the 4 cup (32-ounce) line. Blend again.
- Fill two standard 16-well ice cube trays with the pureed greens. Tap the trays gently on the counter to remove any air bubble and place in freezer.
- Freeze for several hours, preferably overnight, until solid.
- Pop out of ice cube trays and store in a freezer-safe, airtight container. Write the date you frozen on the bag with a sharpie.
- When ready to use, toss 6-8 cubes into blender for any smoothie recipe that calls for 1 cup spinach.
Equipment
- freezer-safe bags
- sharpie marker
Notes
- Swap spinach for kale, romaine, arugula, chard, or other leafy greens you like or combined with spinach.
- Swap water for coconut water for an electrolyte boost.
Is there a taste difference between the cubes and freezing it in bags,? Can the stems be used as well?
Thanks
The cubes take up less space in the freezer and are less messy when adding to the blender. Frozen spinach leaves seem to crumble a bitโย yet the cubes are solid. And def blend in those stems! I use all the spinach!
How to freeze raw cauliflower without blanching
Hi Liz! Id’ wash it well, dry it then cut the florets. From there, put it in freezer bags and you’re good to go!
Thanks for the suggestion but why not buy already frozen spinach? I usually buy it at Trader Joeโs. I also buy frozen mangoes, cherries, and use them in my smoothies. My problem is that in the winter I am not in the mood for a smoothie, only hot beverages. Itโs January now in Philly and I havenโt had one in months. Help!
Hey Janis – great question! We like fresh spinach for it’s ability to be measured easily. Plus when buying frozen, it’s required to thaw out the whole block at once and we might not use it quickly enough. We have some great warm smoothie recipes to get you back in your smoothie game! Check out our Warm Smoothies and let us know what you think. Stay warm!
Great tip!!
I am now freezing my leafy greens…no more wasting and simple to use it all!
Yesssss! That’s awesome Nancy!
Thanks for the tips, I will definitely take advantage of this method. Spinach ice cubes? Who knew!
Right?!?! Happy freezing Nicki!
Great tip!
Thank you for saving my nearly wilted leafy greens! Such a cost effective option vs. the trash or compost.
I love doing this so my spinach doesn’t go bad.
I’ve been doing this for years, but I love how you do it in ice cube trays. Thanks for the tip!
Love this idea of freezing in cubes! too often it gets slimy before I use it all. How many cubes would you use in a single serving smoothie that calls for spinach (fresh)? Thanks for all your great recipes and ideas!
We totally agree Teresa! You can add 4-5 cubes in a smoothie to replace our 1 cup of spinach in most recipes. Happy blending!
Doesn’t the greens lose their nutritional value when frozen this way? I always blanched my vegetables before freezing.
I just buy organic prewashed kale and freeze the whole bag. I take out a handful when I need it for my smoothie.
I bet that works great! ๐
