How to Freeze Raspberries

22 Recipe Ratings

Raspberries are a nutritious snack to have, but they are unfortunately only available during the spring and summer months. By freezing raspberries, you can keep them fresh long after the peak season is over. Frozen fruit is also great for mixing into smoothies, yogurt, and ice cream. Freezing lets you keep raspberries around all year long.

Choosing Raspberries

During peak season, foods are usually the freshest, taste the best, and are least expensive. Peak season for raspberries is usually May through September.^{[1]XResearch source}
Ripe raspberries should be bright red and evenly colored. Dark colored berries may be overripe and won't taste the best. Dark sections on the berries are probably just bruises, which are harmless.^{[2]XResearch source}

Although raspberries are very fragile, they should still be firm to the touch. Gently press on the berries. If they give very easily or are too mushy, they're probably overripe.^{[3]XResearch source}
This can be a sign of overly ripe fruit and is a good environment for mold to grow in.^{[4]XResearch source}
If you see any white or green fuzz on the berries, avoid buying the container. If you've already taken a container home and find mold, be sure to get rid of any berries with mold on them to stop it from spreading. Also get rid of any overly mushy berries, as these are a breeding ground for mold.^{[5]XResearch source}

Freezing the Raspberries

Don't rinse the berries directly under running water- they are fragile and can break apart. Instead, place them in a colander. Then dip the colander in a bowl filled with cold water and swish the berries around.^{[6]XResearch source}
The fastest way to do this is by spreading them out on a paper towel.
Don't allow the berries to touch. They will freeze together and you'll destroy them trying to get them apart.^{[7]XResearch source}
You want to make sure the berries are frozen solid before removing them from the freezer. But leaving them in uncovered for more than a few days will lead to freezer burn, so make sure you don't leave them in much more than a day.
Take them off the sheet and place them in either a freezer bag or a freezer container. Then place them back in the freezer.

Add sugar if you want. As a tasty alternative, you can sweeten the raspberries by adding sugar when you freeze them.^{[8]XResearch source}
- Place a small amount of frozen raspberries in the bag. Then sprinkle sugar on top of the berries. Repeat this layering process until the bag is full.
- Let the fruit defrost for about 15 minutes. This will allow the berries to absorb the sugar.
- Then seal the container and place it in the freezer.
They can stay for up to a year in the freezer. The berries can be eaten while still frozen, or allowed to defrost.

You can certainly eat raspberries frozen, they make tasty treats this way. You can give the frozen raspberries to children as little snacks or sprinkle them over your morning cereal or in your yogurt. Frozen raspberries are perfect for making smoothies and milkshakes too. And if you’re baking, there is no need to thaw, just add to the batter and bake as usual.

The raspberries you choose for freezing need to be perfectly ripe, as once they’re frozen they cannot ripen any further. Choose raspberries that are of a good size, firm but ripe and plump. Avoid using any raspberries that are mushy, falling apart or moldy. Remove any undesirable ones, as well as pieces of leaves, twigs, etc., before preparing the raspberries for freezing. Make sure the raspberries are dry before freezing.

Question
My freezer doesn’t have enough space for the trays, what can I do?

While the tray freezing is a good way to stop the frozen raspberries from sticking together, it is not essential nor is it the only way. Provided you don’t mind the raspberries all clumping together, you can freeze them direct in a container, but you’ll have to accept that they freeze as a mass and you’ll need to “chisel” off clumps of frozen raspberries to use. Or, if you can fit them in a container the size of a standard lunchbox, you can mimic trays by using sheets of parchment paper or wax paper cut to fit the lunchbox-shaped container, and layer the raspberries that way, making sure they don’t touch. You can do several batches this way and transfer the frozen ones to a freezer bag afterward to keep them cold, then re-transfer the lot back to the container once all are frozen whole.
