Prepare a baking sheet (with at least 1/2 in. lip) by laying a piece of parchment paper flat onto the baking sheet.

Wash berries with cold water or fruit wash, and transfer them onto paper towels and allow them to dry completely.

Once dry, prepare berries by removing stems, leaves, and any overly ripe berries.

Transfer berries onto the baking sheet, making sure to spread them out evenly. It's best if the berries are not touching one another so that they don't freeze together.

Freeze for around 30-60 minutes or until berries are hard and completely frozen.

Remove from the freezer and use a spatula to scrape frozen berries off of the baking sheet.

Transfer blueberries into a freezer-safe gallon-size bag. Remove as much air from the bag as possible and seal tightly.

Store berries in the freezer for easy access to smoothies and baking for up to 3 months.
