Freezing is the easiest way to preserve fruit after a picking trip. Done right, frozen fruit keeps its flavour and texture for up to 12 months. Done wrong, you end up with a solid frozen brick that you chip at with a spoon.
Here's how to do it right.
The flash-freeze method
The key to good frozen fruit is freezing pieces individually before bagging them together. This prevents clumping.
Step 1: Wash and dry thoroughly. Rinse your fruit under cold water, then spread on a clean kitchen towel or paper towels and pat completely dry. Excess moisture is the enemy — it creates ice crystals that damage texture and cause clumping.
Step 2: Prep the fruit. Hull strawberries, pit cherries, peel and slice peaches. Leave blueberries, raspberries, and blackberries whole.
Step 3: Freeze in a single layer. Spread the fruit in a single layer on a parchment-lined baking sheet. Make sure pieces aren't touching. Freeze for 2–4 hours until solid.
Step 4: Transfer to bags or containers. Once frozen solid, transfer quickly to freezer bags or airtight containers. Remove as much air as possible before sealing.
That's the whole method. The single-layer step is the only one most people skip — and it's the one that makes the difference.
Fruit-by-fruit guide
Strawberries
Hull before freezing. Freeze whole if using for smoothies or the Ninja Creami. Slice if using for baking. Frozen whole strawberries are ideal for making fruit ice cream.
Shelf life: 10–12 months
Blueberries
The easiest fruit to freeze — no prep needed beyond washing and drying. Pour into a single layer and freeze. Frozen blueberries barely change texture compared to fresh.
Shelf life: 10–12 months
Peaches
Peel first (score the skin, blanch in boiling water for 30 seconds, slip the skin off). Slice into wedges. Toss with a tablespoon of lemon juice per pound to prevent browning. Freeze in a single layer.
Shelf life: 10–12 months
Raspberries and blackberries
Handle gently — they're fragile. Dry very carefully and freeze without washing if possible (rinse immediately before using instead). Frozen raspberries are excellent for ice cream and smoothies.
Shelf life: 8–12 months
Cherries
Pit before freezing — a cherry pitter is worth having if you're processing more than a pound. Freeze whole. Frozen cherries are exceptional in the Ninja Creami.
Shelf life: 10–12 months
Apples and pears
Peel, core, and slice. Toss with lemon juice to prevent browning. Best used for baking after freezing — the texture softens too much for eating fresh.
Shelf life: 8–10 months
Best containers for frozen fruit
Zip freezer bags are the simplest option. Press out all the air before sealing. Label with the fruit and date.
Vacuum-sealed bags are the best option if you're freezing large quantities or want maximum shelf life. A vacuum sealer removes nearly all oxygen, which dramatically reduces freezer burn. Vacuum-sealed fruit easily lasts 12+ months with no quality loss. The FoodSaver is available on Amazon.ca and Amazon.com.

Rigid airtight containers work well for fruit you'll scoop from regularly (like blueberries). Easier to work with than bags, but take up more freezer space.
How to use frozen fruit
- Smoothies — straight from frozen, no thawing needed
- Ninja Creami ice cream — freeze whole, blend from frozen into base (see our ice cream guide)
- Baking — thaw completely and drain excess liquid before using in muffins, cakes, or pies
- Jam — you can make jam from frozen fruit; thaw first and proceed as with fresh
- Yogurt toppings — thaw in the fridge overnight
Common mistakes
Not drying the fruit before freezing. Wet fruit creates sheets of ice and clumps into solid masses.
Skipping the single-layer freeze. Dumping fruit straight into a bag means one frozen block.
Overfilling bags. Thin, flat bags freeze faster and thaw faster. Pack them loosely.
Not labelling. All frozen fruit looks the same after three months. Write the fruit, date, and quantity on the bag.
Frequently asked questions
How long can you freeze strawberries? Up to 12 months at 0°F / -18°C. Quality starts declining after that, though they're still safe to eat.
Do you have to blanch fruit before freezing? No — blanching is for vegetables, not fruit. Fruit can be frozen raw without any heat treatment.
Can you freeze fruit that's starting to go soft? Yes, as long as it's not moldy. Slightly soft fruit freezes just as well and works great in smoothies and ice cream where texture doesn't matter.
What's the best way to thaw frozen fruit? In the fridge overnight. For smoothies and Ninja Creami, you don't need to thaw at all — use straight from frozen.
