Unlike some vegetables, it is necessary to blanch fresh carrots briefly before freezing them. The blanching process helps to break down enzymes that can cause the carrots to lose nutrients when frozen. This also helps carrots retain their color.
Done properly, frozen fresh carrots will last for up to 8 months.
Step 1: Prep the carrots
Trim both ends of the carrots and peel all of the skin away. Rinse the carrots under cool running water and cut them into chunks, slices or strips.
Step 2: Blanch the carrots
Add the carrots to boiling water. Small whole carrots and large chunks take 5 minutes, while slices and strips take 2 minutes. Remove the carrots and add them to a bowl of ice water to stop the cooking process.
Step 3: Bag and freeze the carrots
Pat the carrots dry with a kitchen towel or paper towel. Place the carrots in small plastic resealable freezer bags. Squeeze all of the air from the bag and place flat in the freezer. After a day, the carrots can be placed anywhere in the freezer.
