How to dehydrate cubed potatoes for long-lasting storage and easy meal prep. This step-by-step guide covers all the steps needed from prep work, blanching, and drying for perfect results.
Scrub potatoes thoroughly to remove dirt. Peel potatoes, removing any eyes, and place them in a bowl of cold water to prevent browning. Cut potatoes into 1-inch cubes.
Boil a large pot of salted water. Add potatoes and blanch for 4 minutes once the water returns to a rolling boil. Immediately transfer potatoes to an ice bath to stop cooking.
Spread potato cubes in a single layer on mesh-lined dehydrator trays. Load trays, cover, and set the dehydrator to 125°F. Dry for about 12 hours, checking periodically.
After 4 hours, flip the cubes and rotate trays. Potatoes should be completely hard with no softness in the center. Remove smaller pieces as they finish and continue drying larger ones.
