Learn the easiest method for how to freeze blueberries to use later in baked goods, smoothies, oatmeal, and more. Save money by stocking up when the berries on sale and preserve the best flavor!
How to Freeze Blueberries
There’s typically a time in the summer when blueberries are on super sale at the grocery store, so I like to stock the freezer for future months. And freezing blueberries is a great way to extend the life of fruit with hardly any effort and preserve both the nutrients and peak flavor.
You can use this method with one pint of extra berries or a whole flat if you pick or buy a bunch!
TIP: This method can be used all year long, though blueberries are often on sale in North America in the summer when they are at their peak and in abundant supply.
Ingredients You Need
To freeze blueberries, all you need are fresh blueberries—of any variety including regular, wild, or jumbo blueberries. Then, grab a freezer bag (or a few) depending on how many berries you have to freeze.
You can use plastic freezer bags or the reusable kind from a brand like Stasher.
How to Freeze Blueberries, Step-by-Step
Here’s a look at the simple process involved in freezing fresh blueberries. Scroll down for the full info and tips.
- Sort your berries and discard any that are blemished.
- Wash them gently.
- Dry them on a clean kitchen towel. You can let them sit on the towel for an hour or so to fully air dry.
- Fill a freezer bag half way, seal, remove as much air as possible, and press into a flat layer. The flat layer helps prevent the berries from freezing together, which makes it easier to measure out later.
TIP: You can freeze berries for 6-12 months.
What do I need to freeze blueberries?
You just need berries and freezer bags. If you have just one pint, you can use quart-size freezer bags. If you have more than that, opt for a gallon size.
You’ll need to leave some space in the bags so you can freeze the berries flat in an even layer, which helps prevent them from freezing together.
Recipes for Frozen Blueberries

Favorite Blueberry Banana Smoothie This quick and easy Blueberry Banana Smoothie is a great option for breakfast, snack time, or even dessert.

(Like Little Bites, but with more nutrients and for less $$.) See Notes for allergy variations. Get the recipe Favorite Lemon Blueberry Muffins Serve these warm, at room temperature or cold.

To be able to use them directly from frozen in baked goods and other recipes, yes, you should wash them first so that they’re ready to use.

Thawed frozen blueberries will never have the same texture as fresh ones, but if you plan to use them in baked goods or smoothies, you don’t need to worry about the texture!
