Preparing Sweet Potatoes for Freezing

Before freezing sweet potatoes, it is essential to properly prepare them. Follow these steps to ensure the best results:


Start by washing the sweet potatoes thoroughly under cold running water. Use a vegetable brush to remove any dirt or debris, paying special attention to the crevices and rough spots. Cleaning the sweet potatoes will rid them of any dirt or bacteria that could affect their quality during freezing.


Once the sweet potatoes are clean, peel off the skin using a vegetable peeler or a sharp knife. Removing the skin will prevent it from becoming rubbery or tough when frozen. However, if you prefer to keep the skin on, you can skip this step.


After peeling, you have the option to leave the sweet potatoes whole or cut them into desired shapes. If you plan on using them for dishes like mashed sweet potatoes or fries, it’s best to cut them into smaller pieces. However, if you prefer to store them as whole sweet potatoes for future cooking versatility, leave them uncut.

Blanching Sweet Potatoes

Blanching is a crucial step in the freezing process as it helps maintain the texture, color, and flavor of the sweet potatoes. Follow these instructions to blanch sweet potatoes effectively:

Boiling Water:

Fill a large pot with water and bring it to a rolling boil. The pot should be big enough to accommodate the sweet potatoes without overcrowding.


If you prefer, you can pre-blanch the sweet potatoes before the actual blanching process. Pre-blanching entails dipping the sweet potatoes in boiling water for 3-5 minutes, then immediately transferring them to an ice bath to halt the cooking process. Pre-blanching can help retain the color and texture of the sweet potatoes, but it is an optional step.

Main Blanching:

Gently lower the sweet potatoes into the pot of boiling water, making sure they are completely submerged. Let them boil for about 5-7 minutes for smaller pieces and 8-10 minutes for larger pieces, maintaining a consistent boil throughout.


After blanching, promptly transfer the sweet potatoes to an ice bath using a slotted spoon or tongs. The ice bath will stop the cooking process and prevent further softening. Let them cool for the same amount of time they were blanched.


Once the sweet potatoes have cooled, remove them from the ice bath and allow them to drain. Pat them dry using a clean cloth or paper towels to remove excess moisture.

Packaging and Freezing Sweet Potatoes

Proper packaging ensures that the sweet potatoes remain fresh and intact during freezing. Follow these steps for packaging and freezing sweet potatoes:

Container Selection:

Choose airtight, freezer-safe containers or bags for storing the sweet potatoes. Make sure they are in good condition and thoroughly cleaned. These containers will protect the sweet potatoes from freezer burn and moisture loss.

Individual Wrapping:

If you want to freeze the sweet potatoes individually, wrap each piece tightly in plastic wrap or place them in a single layer on a baking sheet lined with parchment paper. This method allows you to remove individual portions when needed.


Before placing the sweet potatoes in the containers, it is essential to label them with the date of freezing. This practice ensures that you use the oldest sweet potatoes first and maintain a proper rotation.


Fill the containers with the blanched sweet potatoes, leaving about half an inch of headspace to allow for expansion during freezing. For freezer bags, remove as much air as possible and seal them tightly to prevent freezer burn.


Place the packaged sweet potatoes in the freezer, making sure they are arranged in a single layer until they are fully frozen. Once frozen, you can stack or store them more efficiently.

Thawing and Using Frozen Sweet Potatoes

When you are ready to use the frozen sweet potatoes, it’s important to thaw them correctly to maintain their quality and taste. Here are the recommended methods for thawing frozen sweet potatoes:

Refrigerator Thawing:

The safest method for thawing sweet potatoes is to transfer them from the freezer to the refrigerator. Place the desired quantity of sweet potatoes in a container or on a plate and let them thaw overnight. Thawed sweet potatoes can be used within 2-3 days.

Water Bath Thawing:

If you do not have enough time for refrigerator thawing, you can use a water bath. Ensure the sweet potatoes are tightly sealed to prevent water from seeping in. Submerge the packaging in cold water, changing the water every 30 minutes to hasten the thawing process. Once thawed, cook the sweet potatoes immediately.
