How to Freeze Blueberries

Buying blueberries in season from a local farm is a great way to get the best tasting and best quality food you can afford. Freezing them is the best way to get the most bang for your buck. You get to support local farmers and your local economy, be outside in nature at a beautiful farm, create precious memories with your child and have access to the best quality and best tasting produce all year long (after freezing them in bulk that is).

I love picking blueberries with my daughter and I look forward blueberry season all year. My favorite u-pick blueberry farm is right next to a river and we always go swimming after to cool off.

To flash freeze blueberries it is a bit of a process and requires more freezer space than just a small side door freezer, but I think the extra work is so worth it. To freeze blueberries, pick off all the stems and pick out any red and not fully ripe berries, and any that have been crushed or cracked. Then spread them out on cookie sheets and put them in the freezer. DO NOT wash them before you lay them on the cookie sheets to flash freeze them. 

How to Freeze Blueberries

Put the sheets of blueberries in the deep freezer, or the regular freezer if you don’t have one. I let them freeze for about an hour and then take them out and put them in gallon freezer bags. Once you’ve bagged all the frozen blueberries, put them back in the freezer, laid flat, like bricks. By freezing them on the cookie sheets first, the berries do not stick together in the bag and you can scoop out a cup at time as needed. Blueberries in a deep freezer last about a year and in a regular freezer they last about six months.

There are other ways to freeze blueberries, that is just my preferred method for when I’m planning to use them in smoothies, pies, pancakes, and muffins. This is how I have done it for years and years and I think it’s the fastest, most efficient way to do it without compromising on taste. Some people wash and dry them before flash freezing and some cover them with sugar.

We found the organic blueberry u-pick farm by searching It’s a great site to help you find organic, local and farm fresh foods. You can find other resources for produce here. Even if you don’t go blueberry picking, buying pre-picked blueberries in bulk from your local farm or grocery store is a great way to save money and get better tasting blueberries.

    Growing up we had lots of wild blueberries around our house. My Dad loved blueberry pie, so he would dutifully pick them so my Mother would bake pie. We had so many blueberries, that one of the things my mom would do is freeze the blueberries as pies minus the crust. She would make the filling, line the pie plate with foil, fill, and once frozen, wrap the filling and take it out of the pie plate. We would have a stack of blueberry pie fillings in the freezer to last us awhile. When my Dad wanted pie she would put the frozen filling in a pie crust and bake. They always came out perfect but I don’t know how she baked the frozen filling without burning the crust. I know this has nothing really to do with your post …just the freezing and blueberry part reminded me of it 🙂 I only have a small side-by-side freezer…so I can’t stock up too much unfortunately….but enjoyed this and reading some on the crockpot recipes.
