Preserving Perfection: Freezing Whole Potatoes for Long-Term Freshness

Can you freeze whole potatoes?

Potatoes are a versatile and popular vegetable that can be prepared in many different ways. However, sometimes you may find yourself with a surplus of potatoes and wonder if it’s possible to freeze them for later use. In this article we will explore this question: Can you freeze whole potatoes?

Myth or reality: Freezing Whole Potatoes

There is a common misconception that freezing whole potatoes causes them to turn black and become mushy. However, this is a myth. Whole potatoes can actually be frozen while retaining their nutrition, flavor, and texture, as long as they are frozen carefully. With proper methods, frozen whole potatoes can last up to a year in the freezer.

Freezing Raw Potatoes

Raw potatoes have a high water content, which can lead to undesirable results if not frozen properly. When raw potatoes are frozen, the water in them forms ice crystals. When thawed, these ice crystals can cause the structure of the potato to break down, resulting in a mushy texture.
To prevent this, it is important to either blanch raw potatoes or freeze them after cooking and cooling. Blanching involves briefly immersing the potatoes in boiling water and then cooling them in ice water. This process helps preserve the texture and quality of the potatoes during freezing.
If you choose to freeze completely raw potatoes, it is best to cut them into small, bite-sized pieces and use an acid, such as white vinegar or citric acid, to protect them. However, freezing raw potatoes is generally less advisable than blanching or cooking them before freezing.

Freezing whole potatoes: Size Matters

The size of the potatoes plays a crucial role in determining the best method for freezing them whole. Small potatoes, such as new potatoes or baby potatoes, are easier to freeze whole. Blanching, boiling, baking or roasting these small potatoes before freezing can help preserve their texture and quality.
On the other hand, larger baking potatoes do not freeze well raw. Due to their size, blanching may not penetrate to the core of the potato, resulting in compromised texture. It is recommended that larger potatoes be cooked before freezing.

Blanching Whole Potatoes

Blanching is an effective way to preserve the texture and quality of baby potatoes. Follow these steps to blanch baby potatoes:

  1. Wash or peel the baby potatoes.
  2. Bring a large pot of water to a boil.
  3. Fill a large bowl with ice water and hold it ready.
  4. Add the baby potatoes to the boiling water and boil for 5 minutes.
  5. Using a slotted spoon, transfer the potatoes to a bowl of ice water and let them cool for 5 minutes.
  6. Spread the cooled potatoes on a clean kitchen towel or paper towels and air dry thoroughly.

Freezing Blanched Potatoes

Once the blanched baby potatoes are cooled and completely dry, they are ready to freeze. Follow these steps:

  1. Transfer the potatoes to a freezer-safe bag that is labeled and dated.
  2. Make sure the potatoes are in a single layer in the bag, without overlapping or crushing.
  3. Remove as much air as possible from the bag without crushing the potatoes.
  4. Place the bag on a flat surface, such as a baking sheet, and place in the freezer.
  5. Do not disturb or crush the potatoes until they are completely frozen.
  6. Once frozen, store the bag of potatoes in a convenient location in the freezer.

Freezing Cooked Potatoes

Cooked potatoes, whether whole or cut, freeze well and can maintain their quality after thawing. The enzymes that degrade the color, texture and flavor of potatoes have been deactivated during the cooking process. To freeze cooked potatoes, follow these steps:

  1. Bake or roast potatoes until approximately 80% cooked.
  2. Allow potatoes to cool naturally at room temperature, which will help them release excess water and maintain texture quality.
  3. Once the potatoes are completely cooled, transfer them to a freezer-safe bag or wrap each potato individually in aluminum foil.
  4. For batch freezing, place the cooled potatoes in a bag, making sure they are in a single layer without overlapping.
  5. Squeeze out as much air as possible and seal the bag tightly.
  6. For individual freezing, wrap each potato tightly in aluminum foil, making sure there are no holes or areas where air or moisture can enter.
  7. Label the bag or foil with the date.
  8. Place the bag or wrapped potatoes in the freezer, making sure they are flat until completely frozen.

Storage and Shelf Life

When properly prepared and frozen, potatoes can remain fresh and safe in the freezer for up to a year. However, it is important to check frozen potatoes regularly for signs of freezer burn or spoilage. To maximize shelf life, it is recommended that frozen potatoes be consumed within six to eight months.

Thawing and using frozen potatoes

When you’re ready to use your frozen potatoes, it’s important to thaw them properly to maintain their quality. There are several methods for thawing frozen potatoes:

  1. Refrigerator thawing: Place frozen potatoes in the refrigerator and allow them to thaw slowly overnight or for several hours. This method helps preserve the texture and flavor of the potatoes.
  2. Cold water thawing: If you need to thaw potatoes more quickly, you can submerge the sealed bag or wrapped potatoes in cold water. Change the water every 30 minutes to keep it cold. Thawing using this method will take approximately one to two hours.

Once the potatoes are thawed, they can be used in a variety of recipes. Keep in mind, however, that the texture of the potatoes may be slightly different from fresh potatoes. Thawed potatoes are best used in dishes such as soups, stews, casseroles and mashed potatoes.

Tips for freezing potatoes

For best results when freezing whole potatoes, follow these tips:

  1. Choose potatoes that are fresh and show no signs of decay or damage.
  2. Properly clean and dry potatoes before blanching or cooking.
  3. Use quality freezer bags or airtight containers to prevent freezer burn.
  4. Remove as much air as possible from bags to minimize the risk of freezer burn.
  5. Label the bags or film with the freezing date for easy identification.
  6. Freeze potatoes in portions appropriate for your future needs to avoid unnecessary thawing and refreezing.
  7. Keep freezer temperature at or below 0°F (-18°C) for optimal preservation.

Bottom line

In conclusion, freezing whole potatoes is indeed possible and can be a convenient way to preserve an excess supply of potatoes. Whether you choose to blanch or cook them before freezing, with proper preparation and storage, frozen potatoes can retain their nutrition, flavor and texture for an extended period of time.
Remember to follow the recommended methods for blanching or cooking potatoes and ensure that they are sufficiently cooled before freezing. Also, consider the size of the potatoes and choose the appropriate method.
By understanding the proper techniques for freezing whole potatoes, you can minimize waste and enjoy the convenience of having potatoes readily available for future culinary endeavors.


Can I freeze raw potatoes without cooking or blanching?

No, freezing raw potatoes without any pre-treatment can result in a mushy texture and compromised quality. It is recommended to either blanch or cook the potatoes before freezing.

How long will frozen whole potatoes last in the freezer?

When stored properly, frozen whole potatoes can last up to a year in the freezer. However, for best quality, they should be consumed within six to eight months.

Can I freeze large baking potatoes without boiling them first?

It is not recommended to freeze large baking potatoes without cooking them first. Due to their size, blanching may not effectively penetrate the flesh, resulting in poor texture. It is best to cook large potatoes before freezing.

Why blanch potatoes before freezing?

Blanching potatoes before freezing helps to inactivate enzymes that can cause color, texture and flavor degradation over time. It also helps maintain the texture and quality of the potatoes during the freezing process.

Can I freeze whole potatoes and then use them to make mashed potatoes?

Yes, you can freeze whole potatoes and use them later to make mashed potatoes. Once thawed, the potatoes can be peeled and mashed as usual. Keep in mind, however, that the texture of thawed potatoes may be slightly different from fresh potatoes.

What is the best way to thaw frozen whole potatoes?

The best way to thaw frozen whole potatoes is to place them in the refrigerator and allow them to thaw slowly overnight or over several hours. This method helps preserve the texture and flavor of the potatoes. Alternatively, you can thaw them more quickly by submerging the sealed bag or bagged potatoes in cold water, changing the water every 30 minutes.
