Whether you've gone u-picking or got a great deal on blueberries, or you grow your own, you're likely wanting to know how to freeze blueberries. Here's the easiest way to do that so you can store up the extras for future use in smoothies, sauces, pudding, baked goods, or even delicious berry-snacking right out of the freezer bag.

One of the best ways to save money on whole foods is to buy them in bulk when you can get good savings, and store them for the future. I've written about How to Store Nuts and Seeds, How to Store Prepared Beans, and How to Store Leafy Greens, but today I'm sharing how to store one of our favorite foods–how to freeze blueberries.

I guess this post could also be called  “How to Freeze Blueberries Without Having Them End Up in One Big Clump!”

or “The Easiest Way to Preserve Blueberries.”  Because I've tried other ways and this is just well–simply the easiest.

We love blueberries.  And though we are all on sugar-free and even high sugar fruit-free diets due to candida, blueberries are fairly low in sugar and so this year we decided we just had to go picking.

We live in Michigan, one of the great states to live in if you like blueberries and we even have a large wild raspberry bush in our backyard.  Well, it really is in our neighbor's yard but it cascades into ours and it's a house that gets rented out to students and the owner is fine with us claiming the berries as our own.

We are all too happy to oblige.

Over the past 5 years or so we have made it a tradition to go to a U-pick farm and pick too many a lot of blueberries.  And sometimes raspberries, but they don't transport as well.

There is a great organic blueberry farm that has the most delectable berries, but this year, the crazy weather made it so that they weren't offering the U-pick option.  So we had to go to our old standby–a farm that isn't organic but at least doesn't spray.

In years past, this farm had recordings of birds to scare other birds away, but this year, as we were driving up to the farm, we saw two huge birds fly away.  I suspect that they were falcons, seeing as this seems to be a new technique that berry farmers use to scare smaller birds away from their crops.  Interesting, huh?

Anyway, we had limited time this year due to a ton of rain and a busy schedule, but in 1.5 hours of picking time, we managed to pick about 17 pounds of berries.  (And we ate a few as well :-).)

So–now it's time to do something with ‘dem berries.  And though I love the thought of dehydrating them in my faithful preservation companion, the Excalibur Dehydrator, I've never had good luck dehydrating berries.

If you want to preserve berries the right way, freezing them is the way to go, but it's important that you do it the right way.

If you instead put them all in a bag and freeze them, you'll end up with a big chunk of berries and possibly berry mush that you'll need a jack hammer to break apart.

Good for you that instead you can learn the best way to freeze blueberries.

Oh and by the way, you can see why we went blueberry picking (and why we go every year).
I just couldn't say “no” to this smile!

Instructions

  • Wash blueberries and drain.
  • Place blueberries in a single layer on a cookie sheet or jelly roll pan.
    Freeze Berries
  • Place in freezer until frozen, about 7 hours, or overnight.
  • Transfer berries to a sturdy plastic bag like a Ziploc bag or another freezer safe container.  If using a bag, squeeze most of the air out and store in freezer.  Those Twixit Clips that you see on the bag below are one of my most favorite kitchen tools.  I use them for all my plastic bag storage needs.
  • Frozen berries are best used within 6 months, but we've eaten some out of our deep freeze after a lot longer time than that!  
  • Enjoy!

Notes

Freezer tip: If you store food that you won't be using for a long time in a manual defrost freezer, you will avoid freezer burn more easily, and they will last longer.

  1. Great post, Adrienne!

    I also buy fresh fruit and freeze it – especially in the summer. It’s a big part of keeping my kitchen green.

    Just a tip for your readers that don’t use plastic in their kitchen: after you freeze the berries, they can go right into an air-tight glass container. The berries will keep for weeks in there (if they even last that long).

    And that picture is just too cute, Adrienne.

  2. Open freezing berries really is such an excellent technique – it works really well. Thank you for sharing this really helpful tutorial!

  3. Yummmm! My mom is growing blueberries in her back yard. I have a feeling they aren’t going to last long enough to freeze though! 😉
    A few years back my in-laws and I went to a U-Pick blueberry farm. I had blueberries coming out of my ears. I froze most of them, but they did tend to stick in a giant clump. Thanks for sharing your method at Living Green Tuesdays!

  4. Both my girls love eating frozen blueberries. We don’t have anywhere around here to pick them, so just buy them already frozen. They’re great mixed with homemade yoghurt (no other sweetener necessary), whizzed into smoothies, sprinkled on pancakes or just eaten as a snack of there own.

  5. I have heard that rinsing berries in water with a bit of vinegar will prevent mold from growing on them, so you can store them in the fridge longer. Have you ever tried that? This is a great tip–it is more time consuming to pre-freeze the berries, but so worth it!

    1. Never heard that. Makes sense…but I would think it would leave a vinegar-ey tastes. Thanks!!

  6. I would love to know the name/place of the blueberry farm! My mom used to freeze her blueberries this way. After rinsing my berries, I actually roll mine around on a microfiber towel on a bar pan and put them in a freezer bag to freeze. No frozen together chunks of berries.
