Learn how to freeze raspberries so they stay loose and easy to use. This simple method preserves fresh raspberries for smoothies, baking, sauces, and jam.
Gently rinse the raspberries under cool running water if needed. Remove any stems, leaves, or damaged berries. Pat dry or air dry completely.
Arrange on a baking sheet:
Line a baking sheet with parchment paper. Spread the raspberries in a single layer so they are not touching.
Flash freeze:
Place the baking sheet in the freezer and freeze until the raspberries are firm, about 1 to 2 hours.
Transfer to freezer storage:
Once frozen, transfer the raspberries to a quart-size freezer bag or similar container. Remove as much air as possible, label, and return to the freezer.
Notes
1 pound of raspberries will fill approximately one quart-size freezer bag.For best quality, use frozen raspberries within 8 to 12 months.
