Contain it
Choose freezer safe, air tight containers. Not every container is going to withstand low temperatures well, so you want to make sure it won’t crack on you. Freezer burn is also a concern, so you want to be doubly sure you won’t go to pull out a snack only to find it’s ruined. Try either a freezer safe mason jar or a set of these cute shatterproof juice bottles from Amazon.
Cube it
You can also choose to freeze your smoothies in the form of ice cubes. This is a great choice for freezing smaller amounts of smoothie, and will allow for quicker defrosting. Tip: If you want to give it a quick turn in the blender after you take it out of the freezer, having it frozen in smaller pieces will make it easier.
Zip it
Ziploc bags are another good option to consider. For those that don’t have a ton of room for storing larger containers in your freezer, you can use freezer Ziplocs to store them flat on a shelf. If you’re not crazy about spending a ton on single-use plastic baggies that you’re just going to toss, the rainforest will love it if you use these reusable bags from Amazon. Should you go this route, line a sturdy container with the bag before pouring to avoid spills.
Pop it
If you’re feeling frisky, get some popsicle molds and make a few smoothie pops. This is a great way to use that extra smoothie mix if you’re looking to switch things up. If you have littles running around the house or visiting regularly, it would make a good, healthy snack for them too! (But if you want to save it for yourself instead, I’ll keep your secret.)
PROTIP: If you do choose to use a container like a freezer safe mason jar or food container, leave a bit of room in the container. When the smoothie freezes it’ll expand and you want to leave it some room to do so. Otherwise you’ll have a cracked dish in your freezer and you don’t need that damper getting in the way of your afternoon snack time.
When you get ready to take a serving of smoothie out of the freezer, either stick it in the fridge to thaw overnight or leave it on the counter to speed things up.
You could also let your smoothie thaw in the fridge for a bit, then run it through a blender for a slushier texture. This is perfect for those hot summer days.
You can freeze smoothies for at least three months before they start getting questionable. I’ve left them in the freezer for longer, but different freezers and different settings can make them ruin quicker. Mark the date on the container or bag that you store them in, so you can keep up with how long they’ve been in storage, just to be safe.
