Why Learn How to Freeze Blueberries

  • Cost-efficient food preservation: Stock up on blueberries when they are in season and at their lowest price. You’ll save money and enjoy fresh-picked berries for months to come. Sounds like a win-win to me.
  • Conveniently ready to go: Frozen blueberries are always ready to be added to a blueberry smoothie, dessert, or other recipe. They’re even great on top of a yogurt parfait. Their high water content causes them to thaw almost instantly, making them a refreshing treat.
  • Good for you: Blueberries are packed with vitamins, antioxidants, and fiber, making them a nutritional powerhouse. And the good news is that freezing these tiny berries at their peak preserves most of their nutritional value.

  • Fresh blueberries – Stock up and freeze blueberries when they’re in season. That’s when they are sweet, juicy, and ripe. Blueberry harvesting season in the U.S. runs from April through July. When buying blueberries, choose berries that are similar in size, plump, with smooth, unblemished skin that’s deep purple. Avoid red berries as they aren’t fully ripe.

How to Freeze Blueberries

Freezing blueberries is an easy and fun task. You want to make sure you start with firm blueberries. Wash them well in a colander, dry them, then freeze them individually on a rimmed sheet. The last step is the most rewarding – transferring them into a storage bag for your enjoyment for months to come!

Wash the Blueberries

  1. Wash the blueberries with cold water and drain using a colander.
  2. Transfer the blueberries to a kitchen towel and spread out in a single layer. Allow them to air dry well.

Tips for Freezing Fresh Blueberries

  1. Dry the blueberries thoroughly. Spread the washed blueberries on a clean kitchen towel and spread them evenly. Allow them to air dry for at least 15-20 minutes to ensure there’s no residual moisture.
  2. Mind the freezing time. Do not leave the blueberries in the freezer for more than 4 hours during the flash-freezing; otherwise, they will get freezer burn.
  3. Properly store them. After transferring the frozen blueberries into freezer bags or containers, remove as much air as possible before sealing them. This helps prevent freezer burn.
  4. Remember to label. Label the storage containers or bags with the freezing date so you can keep track of how long the blueberries have been stored. Make sure to use them within one year.
