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.

  1. Sort your berries and discard any that are blemished.
  2. Wash them gently.
  3. Dry them on a clean kitchen towel. You can let them sit on the towel for an hour or so to fully air dry.
  4. 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

Here are some kid-friendly blueberry recipes that we love and recommend for ways to use your frozen blueberry stash:

Simple Blueberry Banana Smoothie
Frozen banana will create a slightly thicker smoothie, so if you plan to serve this through a straw, I recommend doing either frozen blueberries OR bananas, but not both. You can do all frozen fruit if you plan to serve it through a pouch or in an open cup—or if your child is used to drinking thick smoothies!

Favorite Blueberry Mini Muffins
Fluffy and perfectly moist, these little muffins have protein and calcium—plus bursts of delicious blueberries. (Like Little Bites, but with more nutrients and for less $$.) See Notes for allergy variations.

Favorite Lemon Blueberry Muffins
Serve these warm, at room temperature or cold. We like a little extra honey on top, but jam, almond butter, or butter would work too. (Adapted from my Raspberry Baked Donuts recipe.)

Blueberry Chia Seed Jam
You can make this with fresh or frozen blueberries. Use the yogurt option to turn it into a quick and easy chia seed pudding.

Favorite Blueberry Banana Bread
This bread is incredibly moist from the bananas and berries, so it takes a little while to bake through. I add foil in Step 4 to prevent it from becoming too brown.

Blueberry Date Bars
This recipe makes about 16 bars, depending on how large you make your slices, so cut them into the size that you want for your family. Cutting 4 rows each way to get 16 bars is usually the perfect size snack for myself and my kids (though sometimes I eat two at once!).

Blueberry Popsicles (with Yogurt and Spinach)
If you have a high powered blender you can add up to a cup of spinach. If you’re relying on a food processor you may want to reduce it to ½ cup. Start with the lower amount and add more as you like.

Easy Oatmeal Bars with Blueberry and Carrot
These oatmeal bars taste like an oatmeal cookie and are great for breakfast or snack. You can make them ahead, too! (You can add the egg or leave it out. Without egg, these are a crisp cookie bar texture. With it, they're a little cakier.)

Frequently Asked Questions

Should you wash blueberries before freezing them?

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.

How do you freeze blueberries without getting mushy?

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!

Can I freeze blueberries in ziplock bag?

Yes, I prefer to add the berries to a bag about half full, gently press the berries flat into an even layer, and remove as much air from the bag as possible before sealing. Freezing them in a single layer helps prevent the berries from freezing together so you can easily measure them out to use in recipes.

How do you defrost frozen blueberries?

You an add frozen blueberries directly to recipes including muffins, breads, oatmeals, and smoothies. So in most cases, you don’t have to defrost them before using.

Does freezing blueberries destroy their antioxidants?

No, there is no significant difference in the antioxidant levels of fresh, frozen, or dried blueberries.

How to Store

Freeze berries in a freezer bag with as much air removed as possible for 6-12 months. Add them directly (still frozen) to recipes.

Best Tips for Success

  • Do as few or as many berries as you like. Use a quart-size freezer bag for one pint and a gallon size for two pints.
  • Fill bags halfway to avoid overfilling and to allow them to freeze in a flat layer.
  • Aim to have the berries totally dry to reduce the chances of them freezing together.
  • Freeze in one, flat even layer to avoid them freezing together.
  • Use in smoothies, muffins, oatmeal, jam, crisp, or any other favorite blueberry recipe.
