How Long Do Sweet Potatoes Last? Do They Go Bad?

Have you ever been left wondering, “Do sweet potatoes go bad? How long should I keep them in my pantry or fridge before they spoil?”

If this is something that has crossed your mind, fear not – you are not alone.

With their creamy texture and sweet taste, sweet potatoes have become a favorite for many home cooks; however, the shelf-life of these much-loved vegetables isn’t always clear.

In this blog post, we will explore how long sweet potatoes last so that you can enjoy them at their best each time!

We’ll also take a look at whether it’s better to store them in the refrigerator or somewhere else like a dark cupboard – plus helpful facts about prepping and cooking your spuds.

What’s Sweet Potato?

Sweet potatoes are a type of tuber that is often confused with yams.

They are, however, two entirely different vegetables.

Sweet potatoes have smooth, reddish-brown skin and orange flesh.

They are also sweeter and less starchy than yams.

Yams, on the other hand, have rough, dark brown skin and white, yellow, or purple flesh.

They are also starchier than sweet potatoes.

Sweet potatoes are a good source of fiber, vitamins A and C, and potassium.

They can be eaten cooked or roasted.

Yams, on the other hand, are a good source of vitamins C and B6, as well as potassium and manganese.

Yams can be boiled, baked, or mashed.

So the next time you’re at the grocery store looking for sweet potatoes, make sure to grab the right vegetable.

How to Store Sweet Potatoes?

One of the best ways to store sweet potatoes is by curing them.

Curing sweet potatoes helps to improve their flavor and texture, and it also makes them last longer.

To cure sweet potatoes, you will need to place them in a cool, dark place for about 10 days.

During this time, the sweet potatoes will develop a thicker skin that will help to protect them from damage.

After curing, you can store sweet potatoes in a cool, dark place for up to six months.

Ideally, you should store them in a temperature-controlled environment like a root cellar or basement.

If you do not have access to a temperature-controlled environment, you can store sweet potatoes in a cool pantry or cupboard.

Just make sure that they are not stored near any sources of heat, as this can cause them to spoil more quickly.

When it comes time to use your stored sweet potatoes, simply wash them off with water and then cook them as desired.

You can bake, boil, or fry sweet potatoes, and they make a delicious addition to any meal.

It’s easy to tell if sweet potatoes have gone bad.

Simply take a look at them and if they have any mold on them, throw them away.

Cut off a small piece of the sweet potato and try frying it or baking it.

If it doesn’t taste right or if it’s mushy, those are both signs that the sweet potato has gone bad.
