Wash the strawberries to remove any dirt or debris. Let dry completely or thoroughly pat dry with a paper towel.
Halve the strawberries (or cut them to your liking) and place them on a baking sheet. Make sure none of the strawberries are touching each other, otherwise they might stick together.
Place the pan in the freezer and freeze for 3-4 hours. Pour all of the berries into a freezer bag and return to the freezer until you're ready to use them. Be sure to date and label the bag so you know what it is and how old it is in the future.
