How to Freeze Almonds & Walnuts (3 Steps)

Freeze shelled almonds and walnuts to keep them fresh for up to two years. Buy nuts in bulk and shell them during the harvest season to freeze and use all year, or take advantage of sales. All nuts contain natural oils that become rancid over time when stored at room temperature, but freezing helps keep them fresh for longer. Freezing almonds and walnuts requires no special equipment or processing, but freshly shelled nuts should be dried in a single layer for 24 hours before freezing.
