Rinse and Dry: Gently rinse fresh berries under cold water. Lay them on paper towels to drain, then blot any excess water or air dry thoroughly.
Remove the Stems: Use a small paring knife (or strawberry huller if you have one) to cut off the green tops.
Prepare Your Pan: Line a baking sheet with parchment paper. Slice the berries if you prefer, or leave them whole.
Freeze in a Single Layer: Spread berries in a single layer, making sure they don't touch. This prevents a big clump and makes it easier to portion later. Freeze whole berries or sliced ripe strawberries.
Flash-Freeze Strawberries: Place the baking sheet in the freezer for at least 1–2 hours or until the berries are solid.
Transfer and Store: Place frozen strawberries in labeled, freezer-safe bags, plastic freezer containers, or airtight containers. Remove as much air as possible to prevent freezer burn.
Notes
These will last in the freezer for at least 6 months (for the best flavor) or up to a year if they are not eaten before then. I have used them after being frozen for a year and they were still fine. They did develop a few ice crystals, but they worked fine in my favorite recipes, especially this strawberry cobbler.
Line Pan: Use a piece of parchment paper to keep berries from sticking to the sheet pan.
Label and Date: Label and date your plastic freezer bags to keep track of freshness.
Measure: Pre-measure berries before freezing (like 1 or 2 cups of strawberries per bag) for easy use in recipes.
Freeze: Avoid refreezing after thawing to preserve texture and flavor.
How Long to Freeze: For best results, use frozen berries within 6–12 months.
