How to Freeze Blueberries
Don’t just grab a handful of blueberries and throw them in the freezer. You’ll only be left with a large blueberry clump that makes it impossible to remove a portion at a time. This is not an efficient way of freezing blueberries.
Instead, follow these instructions below to freeze them in the best way possible:
Please note that you’ll need several trays to speed this process up if you have many blueberries.
- Place Blueberries on a Tray
First, put a layer of blueberries on a tray and put them in the freezer for approximately 1 hour. While it’s starting to freeze, you should create your second tray, third, fourth, etc. You can put as many trays in as you need to get all the blueberries frozen, providing you have space in your freezer.
Remove from the Freezer
The best thing about this approach is that the blueberries will freeze individually. All you have to do is spread them across the tray and ensure they’re not touching each other. They don’t need to be solidly frozen. They need a hard outer shell. After an hour, they should be frozen and feel hard to the touch.
- Bag Up
Once you’ve removed them from the freezer, you’ll be able to slide them into a plastic container or freezer bag. You’ll note they all fall in individually.
Fill your container with the loose but frozen blueberries. These can then be stored in the freezer for as long as you need.
The best part is you can remove just the blueberries you need.
Don’t forget, the fresher the blueberries are when you freeze them, the better. It will help them keep all their nutrients.
3 Tips for Freezing Blueberries
Now you know how to freeze them, we’ve got our 3 top tips which we strongly recommend following when freezing blueberries to have the best results:
- Flash Freeze – Flashing freeze ensures that none of the berries sticks together. This means you can grab a handful at a time, as and when you need them.
- Create Mixed Berry Bags – Don’t limit yourself to blueberries. All berries freeze well. Spread a mix of berries out on your tray, a flash freeze, then split into mixes in freezer bags.
- Use from Frozen – If you’re making a smoothie, you can use blueberries from frozen. Grab a handful, throw them into a blender with other fruit and blend. The frozen berries will keep it nice and cold.
How Long Can You Freeze Blueberries?
Blueberries should be frozen as fresh as possible. This ensures they retain their nutrient levels and can be stored for the maximum amount of time possible.
It’s a good idea to label and date every bag of blueberries you store to help with this.
Ideally, you should use the blueberries within 6 months of freezing them, although they will retain their flavour and goodness for up to 10 months.
The antioxidants in blueberries are very powerful. They’ve been linked to improved memory function, better eyesight, and even a more efficient cardiovascular system. They even help your body to clean cells and remove old, unneeded ones.
You Can Freeze Blueberries for up to 6 Months
How Do You Defrost Blueberries?
The great thing about freezing them individually is that you can remove a handful for a specific reason. For example, for your morning porridge or mid-morning smoothie, you won’t need to defrost a whole bag any more.
In fact, for most recipes, you’ll find it’s not necessary to defrost the blueberries first. Simply remove them from the freezer, rinse them, and add them to your food.
If you need to defrost them, it’s best to put them in a bowl of room temperature water. A cup of blueberries will defrost in approximately 5 minutes. All you have to do then is drain them, dry them, and use them in your recipe.
Can You Refreeze Blueberries?
We would not recommend refreezing blueberries. They are small, delicate soft fruits. Like most soft fruits, including strawberries and blackberries, refreezing will ruin the texture. The water content will be drawn out of the main body of the blueberry.
When you refreeze blueberries, even more of this water will be drawn out.
Instead, try to flash freeze your blueberries to make it easier to defrost a portion at a time.
Do Blueberries Freeze Well?
Blueberries are one of the ultimate health foods. The good news is that the health benefits are not diminished by freezing them.
In fact, recent research from South Dakota State University suggests that frozen blueberries can actually have more antioxidants than fresh ones.
The process of freezing blueberries causes ice crystals to form on them. These crystals disrupt the structure of the cells in the blueberries. This then forces them to make a compound known as anthocyanins more readily available.
As these are the compounds are the base of antioxidants, an increase in anthocyanins translates to increased antioxidants. This is one time when frozen may actually be better than fresh!
Ultimately, the answer to do blueberries freeze well is yes, very! Best of all, you’re not going to notice a taste difference between fresh and frozen. They both taste fantastic!

Once frozen solid, pop the cubes out and store them in a freezer-safe bag until you need them. You can then just place it in a pan and heat it slowly until it melts.
