Rinse and dry: Gently rinse strawberries in cold water, then pat them dry thoroughly with a clean towel. Moisture can cause ice crystals and clumping.
Hull and slice (optional): Remove the green tops using a knife. You can freeze the strawberries whole or slice them depending on how you plan to use them later.
Line a tray: Place a sheet of parchment paper on a baking tray to prevent sticking.
Arrange strawberries: Spread the berries in a single layer on the tray, making sure they don’t touch. This helps them freeze individually and prevents clumping.
Flash freeze: Place the tray in the freezer for 4 to 6 hours, or until the strawberries are completely frozen solid.
Transfer to containers: Once frozen, move the berries into labeled freezer-safe bags or containers. Remove as much air as possible before sealing.
Store in freezer: Keep frozen strawberries for up to 12 months. Use them as needed in smoothies, baking, sauces, or jams.
