Raspberries, with their vibrant color and sweet-tart flavor, are a delightful addition to smoothies, desserts, and baked goods. Freezing raspberries preserves their freshness and nutrients so you can enjoy them long after harvest season.
Selecting and Preparing Raspberries
Choose Ripe Raspberries
Pick plump, firm raspberries that are fully ripe. Ripe berries will be deep in color, slightly firm on the outside but juicy inside, and should not crush easily.
To Wash or Not to Wash
Some people prefer to wash raspberries before freezing to remove dirt or residues, while others skip washing to avoid adding moisture that can form ice crystals. If you wash them, rinse gently under cool running water in a colander, then dry thoroughly before freezing.
Gently pat the berries with a paper towel and spread them on a clean dish towel until completely dry to reduce excess moisture.
Spread on a Baking Sheet
After drying, arrange the raspberries in a single layer on a rimmed baking sheet lined with parchment paper. This keeps the berries from freezing together so you can grab only what you need later.
How to Freeze Fresh Raspberries
Flash Freeze
Place the prepared baking sheet in the freezer and let the berries freeze for about 1–2 hours, or until firm and fully frozen.
Recipe Tip
Make sure the baking sheet fits in your freezer before you load it with berries. If space is tight, use a smaller tray such as an air fryer tray.
Transfer to Ziplock Bags
When the raspberries are solidly frozen, transfer them from the tray into resealable freezer bags or reusable containers. Portioning into smaller batches makes them easier to use for baking or smoothies.
Squeeze Out Air
Press out excess air from the bags before sealing to limit freezer burn and help the berries retain quality. Avoid vacuum sealing if the raspberries are very delicate, as they can crush easily.
Label and Date
Label each bag or container with the freezing date so you can track freshness and use the fruit within recommended storage times.
Storage and Shelf Life
Properly stored frozen raspberries keep well for 10–12 months. Within that time they retain flavor and are suitable for smoothies, baking, sauces, and more.
Ways to Use Frozen Raspberries
Frozen Berries in Smoothies
Frozen raspberries add color, flavor, and nutrition to smoothies. Add them straight from the freezer to your blender for a thick, chilled drink.

Frozen raspberries work well in baked goods like banana bread, muffins, cakes, tarts, crumbles, and jam. They generally hold their flavor and shape during baking, making them a convenient choice for year-round recipes.

Raspberry Jam
Frozen raspberries can be used for both sweet and savory dishes, and they’re especially handy when fresh berries are out of season.

Sugar Pack Raspberries: Freezing Raspberries with Sugar
While I usually freeze fruit without sugar, sugar-packing is useful if you plan to make jam. For about 1 quart of raspberries, sprinkle 3/4 cup sugar over the berries, toss gently, and mash slightly until juice forms and the sugar dissolves. Freeze in a container or bag and label it for later use in jams, pies, or preserves.
You can also pack crushed raspberries without sweetener into small freezer-safe containers to use later for jam or pie filling.

Freezing raspberries is a simple, effective way to preserve their flavor and nutrition. Use them straight from the freezer in smoothies or baking—there’s no need to thaw them first unless a recipe calls for thawed fruit.
If you thaw frozen raspberries they will become soft, so for many applications it’s best to work with them frozen.
Freezing raspberries lets you enjoy the taste of fresh fruit any time of year.
