Step 1

Scrub and peel the sweet potato. Slice it into your desired shape.

Step 2

Bring a large pot of water to a boil. Drop the sweet potatoes into the boiling water. When the water returns to a boil, start a timer and cook for 3 to 5 minutes.

Step 3

In the meantime, fill a large bowl with ice water. When the timer goes off, remove the sweet potatoes promptly from the boiling water using a slotted spoon. Submerge them into the ice water and let them sit in it for a few minutes.

Step 4

Drain the sweet potatoes. Spread them out in a single layer on a baking sheet lined with parchment paper. Place the baking sheet in the freezer (somewhere it can lay flat won't get bumped) for 1 to 2 hours until the sweet potatoes are frozen solid.

Step 5

Transfer the frozen potatoes to a labeled bag or container. Remove as much air as possible before sealing. Store in the freezer for up to 6 months.

Step 6

Cook potatoes as desired. Let them cool completely.

Step 7

If freezing roasted whole sweet potatoes, wrap each one in aluminum foil then place in a bag or container to store in the freezer. Store in the freezer for up to 6 months.

Step 8

For boiled or mashed potatoes, transfer them to bags or containers. If freezing mashed potatoes, use your hands to flatten them in the bag. Squeeze out as much air as possible before sealing. Store in the freezer for up to 6 months.
