There are many uses for frozen blueberries. They can be added to baked goods or thawed for a healthy snack.

Compared to fresh blueberries, frozen ones are just as healthy. The key is to freeze berries when they’re most ripe, when the nutrient content is highest.

Pick plump blueberries.
When shopping for blueberries, choose ones that are plump and firm.
The skin should be a deep purple-blue. If the berries are too green, it means they’re unripe and not sweet.
Skip blueberries that are mushy, moldy, or brown. These are signs that the berries are starting to spoil.
Remove the stems.
Some blueberries might have the stems attached.
Be sure to remove them before freezing. It’s easiest to do this while washing the berries.
Dry the blueberries properly.
After rinsing the blueberries, it’s important to dry them completely.
If the berries are wet, they’ll be more likely to clump together in the freezer.
Dry blueberries will freeze separately, so they’ll be easier to add to recipes.
Use a plate instead of a baking sheet.
If you don’t have a baking sheet that will fit in the freezer, you can use a plate. Only use plates that are made of freezer-safe materials, like ceramic.
A disposable aluminum pie pan also works.

Frozen blueberries can be added directly to recipes, including smoothie. But if you want to eat the blueberries as a snack or topping, just thaw them in the refrigerator.
