Can You Freeze Sweet Potatoes?

Sweet potatoes are a delicious, nutritious root vegetable that can be enjoyed in a variety of dishes. But what if you have too many sweet potatoes and need to store them for later? Can you freeze them?

The short answer is yes! Freezing sweet potatoes is a great way to store them for longer periods. While most vegetables can be frozen with minimal effort, sweet potatoes are slightly different.

Sweet Potatoes

If you try to freeze them without taking special precautions, they will likely become mushy and unpleasant to eat. However, if you take the time to blanch them first, you can freeze sweet potatoes with no problem.

How To Freeze Sweet Potatoes: Cooked Or Raw?

Sweet potatoes are a delicious and nutrient-rich vegetable that can be enjoyed in many different ways. One popular way to enjoy sweet potatoes is to cook them and then freeze them for later.

However, it is also possible to freeze sweet potatoes without cooking them first. So, which is the better method?

There are a few things to consider when deciding whether to freeze sweet potatoes cooked or raw.

First, cooked sweet potatoes will take up less space in your freezer than raw sweet potatoes. That’s because cooked sweet potatoes are softer and thus take up less volume.

Second, cooked sweet potatoes retain flavor and texture better than raw sweet potatoes. The cooking process breaks down some of the cell walls, making it easier for the flavors and nutrients to be released.

Finally, cooked sweet potatoes are more convenient to use than raw sweet potatoes as they can be easily thawed and eaten without any further preparation.

Overall, if you are looking for the best way to preserve your sweet potatoes, cooking them before freezing them is the way to go. However, if you are looking for the most convenient option, then freezing them raw may be a better choice.

How To Freeze Sweet Potatoes (Cooked)

Sweet Potatoes

While freezing sweet potatoes is a simple and effective way to extend their shelf life, there are a few things to keep in mind before starting the process. Here are a few tips to get you started:

Step 1: Start By Washing The Potatoes

Sweet potatoes are packed with nutrients like vitamins A and C, making them a healthy addition to any diet.

But before you can enjoy their flavor and health benefits, you need to know how to wash them properly. Because sweet potatoes are tubers, they can be difficult to clean.

Start by scrubbing them with a brush under running water. This will remove any dirt or debris from their surface. Then, cut away any bruised or damaged areas using a sharp knife. Once they’re clean, dry them off with a towel or paper towel.

Step 2: Peel The Potatoes (Optional)

While you can freeze sweet potatoes with the skin on, many people prefer to peel them before cooking or freezing. This is because the skin can be tough and difficult to eat.

If you decide to peel your sweet potatoes, use a vegetable peeler or paring knife to remove the skin. But be careful not to cut too deeply, as this will remove some of the flesh along with the skin.

Step 3: Fill A Pot With Water And Boil It

Bring the pot of water to a boil and then carefully add the potatoes one by one, taking care not to overcrowd the pot.

Boil them for three to five minutes or until they start to soften. This process is called blanching and will help preserve their color, flavor, and nutrients.

Blanching also kills enzymes that may cause the potatoes to deteriorate, so it’s an important step in the freezing process.

Step 4: Remove The Potatoes From The Water

Once they’re done blanching, use a slotted spoon or tongs to remove the sweet potatoes from the pot of water. Place them on a baking sheet or plate lined with paper towels to absorb any excess moisture.

You can also transfer the cooked potatoes to a bowl of ice water to stop them from cooking any further. This will help to preserve their flavor and texture.

Step 5: Let Them Cool Completely

Before freezing, you need to let the sweet potatoes cool completely. If you try to freeze them while they’re still warm, they will release too much moisture and become mushy.

So, be patient and let them cool down to room temperature before moving on to the next step.

Step 6: Cut The Potatoes Into Slices Or Chunks

Once they’re cool enough to handle, cut the sweet potatoes into desired shapes and sizes before freezing them. This will make it easier to thaw and use them later on. It will also help to prevent them from freezer burning.

Step 7: Place Them In A Freezer-Safe Container

To keep your sweet potatoes fresh, be sure to store them in a freezer-safe container or bag. Before freezing, you can also wrap them tightly in aluminum foil or plastic.

Just ensure there’s no air left in the container so they don’t dehydrate. This will prevent them from drying out or absorbing other flavors in the freezer.

Step 8: Label And Date The Container

Labeling the container with the date will help you track how long they’ve been in the freezer. You can freeze the sweet potatoes for up to 12 months, but they’re best used within the first six months.

How To Store Uncooked Sweet Potatoes

Sweet potatoes must be stored properly to ensure they remain fresh and safe to eat. When storing uncooked sweet potatoes, it is best to keep them in the refrigerator.

This will help to prolong their shelf life and prevent them from going bad. To store sweet potatoes in the fridge, first wash them thoroughly with running water to remove any dirt and debris.

Once they are clean, peel them and cut them into desired shapes and sizes. Place the uncooked pieces of potatoes in an air-tight container filled with water and then store them in the fridge.

The uncooked pieces of potatoes will usually stay fresh for 3-5 days when stored in this way. But be sure to label the bag or container with the date so you can keep track of how long they’ve been stored.

Additionally, check them for signs of spoilage before using them and discard any potatoes that are shriveled, moldy, or have any other signs of deterioration.

You should also change the water every two days to prevent them from going bad if you’re planning on storing them for longer than three days.

Can You Freeze Sweet Potatoes Mashed?

Yes, you can freeze and store sweet potatoes mashed, but there are a few things to remember. First, it’s important to let the mashed potatoes cool completely before freezing them. Otherwise, they may become freezer burnt.

Second, you’ll need to use an airtight container to prevent ice crystals from forming. Finally, when thawing the sweet potatoes, be sure to do so gradually in the refrigerator.

This will help them retain their texture and flavor. If you follow these steps, you’ll be able to enjoy mashed potatoes all year round!

How Long Can You Freeze Sweet Potatoes?

Sweet potatoes are a delicious and nutritious addition to any meal. They can be roasted, mashed, or cut into fries and pair well with sweet and savory flavors.

While fresh sweet potatoes are always the best option, sometimes it’s necessary to freeze them. So, how long can you safely keep sweet potatoes in the freezer?

In general, sweet potatoes can be stored in the freezer for up to six months. However, this may vary depending on how they were prepared before being frozen.

For example, raw sweet potato slices will only last for two or three months in the freezer before they start to lose their flavor.

On the other hand, cooked sweet potatoes that have been mashed or pureed can be stored for up to six months without any significant loss of quality.

What Are The Effects Of Freezing Sweet Potatoes?

Sweet potatoes are quite prized for their sweetness, nutrient content, and versatility. However, like all vegetables, they can begin to spoil soon after harvest if they are not properly stored.

And while freezing them will increase their shelf life, it’s essential to know that freezing can cause some changes in the potato’s texture, taste, and nutrient content. Let’s explore how these versatile vegetables are affected by freezing.

Flavor And Nutrients

When sweet potatoes are frozen, the water inside them begins to form ice crystals. This can cause the cell walls to break down, which leads to a loss of flavor and nutrients.

The loss of sweetness is caused by the cold temperatures inhibiting the conversion of starch to sugar. This dulls the vegetable’s natural sugars, leaving it with a bland taste.

On the other hand, the loss of nutrients is due to the leeching of vitamins and minerals into the surrounding water when the cells are damaged. The nutrients may not be wholly lost, but they can become less bioavailable.


In addition to affecting the flavor, freezing can also change the texture of sweet potatoes. When they’re thawed, they may become mushy or soggy. This is why it’s important to cook them before freezing if you want to maintain their texture.

However, if you’re planning on using them for soups or purees, the change in texture won’t matter as much.

In general, frozen sweet potatoes are best used within six months to maintain the highest quality. After that, they can still be eaten but may not be as flavorful or nutritious.


The color of sweet potatoes can also change after they’ve been frozen.

This is due to the loss of anthocyanins, which are water-soluble pigments that give the vegetable its characteristic orange hue. However, this change in color is usually only noticeable in raw sweet potatoes.

Cooked sweet potatoes will usually retain their color, although the flesh may become duller. This is nothing to worry about and won’t affect the taste of the vegetable.

Is It Advisable To Freeze Sweet Potatoes Without Blanching?

Sweet Potatoes

It is not advisable to freeze raw sweet potatoes without blanching. Sweet potatoes contain enzymes that can cause them to go bad when frozen without blanching.

Blanching helps to inactivate these enzymes and prevents the sweet potatoes from getting mushy or developing an off-flavor when frozen. In addition, blanching also helps to preserve the bright color of the sweet potatoes.

While it is possible to freeze raw sweet potatoes without blanching, it is not advisable as it can impact the quality of the potatoes.

How To Know Your Frozen Sweet Potatoes Are Going Bad

Frozen sweet potatoes can last for up to a year without going bad. However, they will start to go bad eventually. Here are some signs to look out for:

Freezer Burn

Freezer burn refers to when the surface of the sweet potato becomes dehydrated and starts to turn white or brown.

This can happen if the potatoes are not properly sealed before being frozen, which results in the formation of ice crystals on the surface of the potatoes.

Freeze burn results in the evaporation of moisture from the vegetable, leaving it dry, tough, and less flavorful.

While freezer burn doesn’t make the sweet potatoes unsafe to eat, it does affect their flavor and texture. However, if you cut off the affected parts, the rest of the potato can still be eaten.


Mold can also form on frozen sweet potatoes if they are not properly sealed before being stored. Mold is a type of fungus that can cause food to spoil and make it unsafe to eat.

If you see mold on your sweet potatoes, throw them out ASAP. If you eat food affected by mold, you can experience nausea, vomiting, and diarrhea.

Changes In Color Or Texture

As we mentioned before, freezing can cause changes in the texture and color of sweet potatoes. Fortunately, these changes are usually not harmful, and you can still eat them.

But if the changes are drastic or accompanied by other signs of spoilage (like freezer burn or mold), it’s best to throw them out.

Eating them could cause a serious case of food poisoning. Remember, it’s better to be safe than sorry when it comes to frozen sweet potatoes. If in doubt, throw them out!

The Potatoes Are Sticky After Thawing

Have you ever thawed out a bag of frozen sweet potatoes only to find that they’re sticky? This is usually a sign that the potatoes have gone bad.

When sweet potatoes go bad, their starch breaks down and turns into sugar. The breakdown of sugar can cause them to become sticky, gummy, or even slimy. If your sweet potatoes are sticky after thawing, it’s best to throw them out.

They Have An Off Odor

We have all heard the saying, “if it smells off, don’t eat it.” This is especially true for frozen sweet potatoes. If your sweet potatoes have an off odor, this is a sign that they’ve gone bad.

The off odor can be described as sour, musty, or even rotten. Eating rotten food can make you very sick, so it’s best to play it safe and throw out any sweet potatoes that smell off.

The Potatoes Have Started To Disintegrate Or Become Mushy

This often happens when sweet potatoes are stored for too long or not properly sealed before being frozen. If your sweet potatoes have started to disintegrate or become mushy, it’s best to throw them out.

While they may still be safe to eat, they will not be as tasty. No one wants to eat mushy sweet potatoes!

How Can You Keep Cooked Sweet Potatoes Frozen For Longer?

Cooked sweet potatoes can last for up to 6 months in the freezer. However, you can do a few things to help them last even longer. These include:

  • Ensuring that they are properly cooled before being placed in the freezer. Putting hot sweet potatoes in the freezer will cause the surrounding food to thaw and refreeze. This will decrease the quality of the sweet potatoes and make them more likely to spoil.
  • Wrapping them tightly in a freezer-safe bag or container. This will help to prevent freezer burn.
  • Labeling the bags or containers with the date they were frozen. This will help you track how long they’ve been in the freezer.
  • Only thawing out the amount of sweet potatoes you need. If you thaw out a bag of frozen sweet potatoes and don’t use them all, they will only last for a few days in the fridge. Re-freezing them will decrease their quality and make them more likely to spoil.

Following these tips, you can help to ensure that your frozen sweet potatoes will last for as long as possible.
