Frozen veggies that are ready to be added to meals are incredible time savers. Having components ready to go to add to dinners or smoothies helps make your day just a little bit easier.
Of course, you can buy frozen spinach. But if your garden is producing more than you can eat, or you have a bag in the fridge you won’t be able to finish, freezing your own spinach helps reduce waste and saves money.

TOOLS FOR FREEZING Spinach
- Large saucepan
- Strainer/colander
- Reusable freezer bags or muffin tins or ice cube trays or plastic freezer bags
- Ice
- Large bowl
Do you blanch spinach before freezing?
Yes and no. It depends on how you want to use it. If you plan to use the frozen spinach within a few weeks, there is no need to blanch it first.
Unblanched spinach left in the freezer for too long will turn brown because of enzyme actions which will change the texture, flavor, and coloring.
how long do you blanch spinach for freezing?
The spinach just needs two minutes in boiling water for the blanching process.
freezing spinach for smoothies
If you’re planning on using your spinach for smoothies, you can chop it in a food processor or blender with a splash of water until it is puree. I find it easiest to freeze in ice cube trays or silicone trays for smaller and easy-to-blend portions. I’ve even used these silicone egg molds that are for making Instant Pot Egg Bites.
Pro tips/recipe notes
- There is no need to thaw the spinach before adding it to soups or sauces.
- I prefer to freeze spinach in 1 cup portions for adding to things like Instant Pot Lentil Soup, Crockpot Spaghetti Sauce, or a Gluten-Free Quiche. I line a muffin tin with these parchment cupcake liners and they pop right out once frozen and I add them to freezer storage bags. I also love the 1-cup Souper Cubes for that.
- Save the cooled cooking water from blanching the spinach and use it for cooking grains like Instant Pot Farro or for watering houseplants!
- 5 oz of spinach will wilt down to about 1 cup for freezing.

This has been very helpful. For some reason, it’s been almost impossible to find spinach in the frozen food aisle lately. I have a LOT of fresh baby spinach on hand that I need to use up, so finding this pin was quite timely. My morning smoothies say thank you.
I *might* know the answer to that or at least part of it. Because I listened to a supply chain podcast a few months ago and now I’m an “expert”. 🙂
With the supply chain being so wonky, and droughts (or flooding like in the PNW) everywhere, FRESH produce was harder to find and more expensive. But frozen produce often has a 3-4 month inventory in the warehouses so those prices basically remained unchanged.
So, when people couldn’t find fresh items or couldn’t afford them, they turned to frozen. And then probably got used to purchasing it. And now, that inventory is finally starting to catch up with the rest of the supply chain.
Hi! Can I steam the spinach (for better digestion) and then blend it to add to ice cube trays for smoothies?
Absolutely! I would still dunk it in the ice water after steaming though.
Our family garden has been spitting out leafy greens at an alarming rate. I used the method from this post to freeze swiss chard. It was easy, simple, and now I have a freezer full of greens for later!
