Got too many blackberries? Here's how to freeze blackberries along with some of our favorite recipes for using up these delectable summer fruits.

Whether your berry patch in the garden is killing it this year or you just hit the goldmine at the farmers market, you’re here for one reason: you’ve got more blackberries than you can eat!

Since these delicate little fruits don’t last long in the fridge, your options are limited. You can start cooking pies like your life depends on it, serve every meal with a side of berries, or start freezing them so you can enjoy blackberry season all year long.

For the latter option, you’ve come to the right place. Below, we’ll walk you through five simple steps for how to freeze blackberries so none of those precious fruits go to waste. Plus, we’ll tell you how to thaw those delectable berries and how to use them in some of our favorite blackberry recipes.

What You’ll Need

Freezing blackberries is super easy. All you’ll need to get started are:

  • A colander
  • A clean kitchen towel
  • A cookie sheet
  • Parchment paper
  • Freezer-friendly container or bag

The Simplest Way to Freeze Blackberries

Getting your blackberries ready to freeze only takes a few minutes while the freezing process itself takes about 3 hours. For best results, start the below freezing process when your fruits are at the height of ripeness.

Step 1: Wash the Blackberries

For garden and organically grown blackberries, this is as simple as running the sweet berries under cool water using a colander.

If your berries aren’t organic, consider soaking them in a bowl of cool water and vegetable wash for about 5 minutes to remove any pesticides or chemicals. 

Blackberries are fairly fragile, so be gentle during the soaking and rinsing process. Try to avoid jostling the berries too much, as smashed berries do not freeze as well as intact fruits.

Step 2: Lay the Blackberries Out to Dry

Once the berries are rinsed, carefully lay them out to dry on a clean kitchen towel.

Be sure there is adequate space around each berry to allow for optimal airflow. You can dab the berries lightly with a piece of paper towel or rotate them occasionally to speed up the drying process.

After about 5 to 10 minutes, your berries should be fully dry and ready for the next step. 

Step 3: Transfer to Parchment-Lined Cookie Sheet

Find a cookie sheet that is large enough to hold all your berries (or multiple sheets, if needed). Then use parchment paper to line the sheet—this will keep the berries from sticking to the metal as they freeze.

Place the berries on the parchment-lined tray and spread them out so none are touching. The more space between the berries, the faster they will freeze.

Step 4: Place Cookie Tray in the Freezer

Place the cookie tray in the freezer being careful to keep it level so the berries don’t roll around.

Leave the tray in the freezer for at least 3 hours. At this point, the berries should be frozen through and ready to be transferred to another container. You can leave the berries in longer—overnight if needed—but don’t go longer than 12 hours or you’ll risk freezer burn.

Step 5: Transfer Frozen Blackberries to Container

Once the berries are frozen through, transfer them from the cookie tray into a freezer-safe container. Ziplocks, reusable silicone bags, and solid containers will all work well for this.

Be sure to mark the container with the date and use the berries within 1 year.

How to Thaw Blackberries

There are two super-simple methods for thawing frozen berries: the microwave and using cold water.

How to Thaw Blackberries in the Microwave

To thaw blackberries in the microwave, first, place the berries in a microwaveable safe container. Then set your microwave to defrost for 30 seconds. Stir the berries and put them back in for another 30 seconds on defrost. 

One minute is usually enough time to thaw blackberries, but repeat as needed until the berries are defrosted all the way through.

How to Thaw Blackberries Using Cold Water

If keeping your blackberries intact is necessary for your recipe, then you’ll want to skip the microwave in favor of the cold water method.

To thaw your blackberries using the cold water method, simply pour the berries into a large bowl and fill the bowl with cool water. Wait for about 5 to 7 minutes. Once the berries are fully thawed, gently drain the water and enjoy.

How to Use Frozen Blackberries

Thawing your blackberries may or may not be necessary depending on how you plan to use them. 

Smoothies, homemade ice cream, and other cool treats are perfect for using frozen blackberries just as they are. Pies, muffins, and other baked dishes usually call for fresh berries, which means you’ll want to thaw yours before adding them to the recipe.
