Yes, you can freeze blueberries. The simple trick is to dry them thoroughly and freeze them separately on a tray before bagging, so you can scoop out only what you need instead of chiselling through an icy block.

Step-by-step method
- Pick through blueberries and discard any mouldy, split or leaking berries.
- Rinse only if needed, then spread them on a clean tea towel or kitchen paper and dry them thoroughly.
- Arrange the berries in one layer on a lined tray, leaving a little space between them.
- Freeze until firm, then transfer the berries to an airtight labelled freezer bag or container.
- Press excess air from bags, seal them and return the blueberries to the freezer promptly.
- Use berries straight from frozen for smoothies, porridge, sauces and most baking, or thaw in the fridge when needed.
Should you wash blueberries before freezing?
You can rinse blueberries before freezing, but the important step is drying them extremely well. Surface water makes larger ice crystals and can cause berries to clump. If berries are already clean and dry, freezing them as they are is usually simplest.
Can you freeze blueberries in a container?
Yes. A freezer bag saves space, but an airtight container works well too. Tray-freeze first if you want loose berries; otherwise they may set into a solid block in the container.
What are frozen blueberries best for?
Frozen blueberries are excellent in smoothies, porridge, pancakes, muffins, crumbles, sauces and compote. They become softer after thawing, so they are less suited to a fresh fruit salad.
