How to freeze fresh raspberries? Can you freeze them whole? Do you have to wash them? How long do they last?! We’ll answer all your top questions about freezing raspberries and storing them in your freezer long term!




  1. Inspect raspberries for any signs of mold, rot, or soft berries and remove those. 
  2. Place raspberries into a colander, mesh strainer, or sieve and gently rinse under running water, shaking gently to agitate the raspberries as you rinse them.
  3. After rinsing, gently shake the strainer again to remove as much excess water as possible from the raspberries. Extra water will cause the raspberries to develop an icy/ freezer burn layer and can negatively affect the taste and texture.
  4. Lay a few kitchen towels out on top of each other and pour the raspberries onto the towels to dry. You can let them air dry for 20-30 minutes or gently pat them dry with a kitchen towel. 
  5. Line a baking sheet with parchment paper and add rinsed and washed raspberries to the baking sheet in a single layer, preferably not touching one another. Place in the freezer for 4-6 hours.
  6. Once frozen, use a spatula to loosen raspberries from the baking sheet and store in a freezer-safe container or plastic bag.


** Raspberries will keep for up to 1 year in the freezer. Double bagging the plastic bags may help prevent freezer burn!

** To use frozen raspberries in quick breads or quick-cooking items: For waffles, pancakes, or fast-cooked stovetop dishes, thaw raspberries for 30-45 minutes before use. To help thicken the juices that are present when you defrost raspberries, sprinkle 1 tablespoon of cornstarch on every 1 cup of frozen raspberries.

** To use frozen raspberries in baked goods like muffins, scones, and donuts: Keep the raspberries frozen, do not defrost prior to folding into the batter as this may throw off the liquid to dry ratios in the dough. Again, toss every 1 cup raspberries with 1 tablespoon cornstarch to help thicken juices as needed.
