How To Freeze Blackberries: Step-by-Step Guide for Long-Term Freshness

One of the greatest methods to maintain the juicy flavor and nutritional content of blackberries throughout the year is to freeze them. Learn how to properly freeze blackberries to save waste and keep them ready for smoothies, baking, or snacking, whether you’ve picked a large crop or scored a fantastic deal at the market.

This article will teach you how to properly freeze blackberries, as well as how to store them and defrost them to preserve their flavor and texture.

Why Freeze Blackberries?

Blackberries are highly perishable, lasting only a few days when fresh. Freezing them:

  • Extends shelf life for up to 12 months

  • Retains most of its vitamins and antioxidants

  • Makes them perfect for use in smoothies, pies, jams, and sauces

  • Reduces food waste and saves money

What You’ll Need

Before freezing blackberries, gather the following:

  • Fresh, ripe blackberries (avoid overripe or moldy ones)

  • A colander or strainer

  • Baking sheet or tray

  • Parchment paper (optional)

  • Freezer-safe bags or airtight containers

  • Paper towels or a clean dish towel

Step-by-Step: How to Freeze Blackberries

1. Wash the Blackberries

Place the blackberries in a colander and rinse gently under cold running water to remove dirt or debris. Avoid soaking, as blackberries are delicate and can absorb too much water.

2. Dry Thoroughly

Pat the berries dry with a paper towel or let them air dry on a clean kitchen towel. Removing moisture prevents ice crystals from forming and helps preserve texture.

3. Flash Freeze on a Tray

Line a baking sheet with parchment paper and spread the blackberries in a single layer. Make sure they don’t touch—this prevents them from clumping together during freezing.

Place the tray in the freezer for 2–3 hours or until the berries are fully frozen.

4. Transfer to Freezer Bags or Containers

Once frozen, move the blackberries into labeled, freezer-safe bags or containers. Squeeze out as much air as possible before sealing to prevent freezer burn.

5. Store Properly

Store in the back of the freezer (where temperature is most consistent) for up to 12 months.

Tips for Best Results

  • Freeze in portions: Use small bags or containers for easy use in recipes.

  • Label with date: Helps you track freshness.

  • Don’t thaw unless necessary: Add frozen berries directly to smoothies or baked goods.

How To Thaw Frozen Blackberries

To use frozen blackberries in recipes like yogurt bowls or salads:

  • Place them in the fridge for a few hours to thaw slowly.

  • For quick thawing, leave them at room temperature for 30–60 minutes.

  • Avoid microwaving, as it can make them mushy.
