How to Freeze Blueberries
Use fresh blueberries that are completely dry when you pop them in the freezer. Don’t worry about rinsing the berries before you freezethem; simply place them, still in their original containers, in resealable plastic bags and store them on your freezer shelf.
If you prefer to rinse the blueberries first, dry them well with paper towels, then transfer them to freezer containers or resealable plastic bags for freezing. The blueberries will freeze individually so you can remove just the portion you need.
If you didn’t wash your blueberries before freezing them, rinse them just before use.
For best results, toss your home-frozen blueberries into oatmeal, yogurt, smoothies, shakes or sauces within six months.
