In this article, we’ll delve into the world of sweet potato storage, exploring the best practices to keep your sweet potatoes fresh for a longer period.
Understanding Sweet Potato Storage
Before we dive into the washing aspect, it’s essential to understand the basics of sweet potato storage. Sweet potatoes are a type of root vegetable that belongs to the morning glory family. They are sensitive to temperature, humidity, and light, which can affect their quality and shelf life.

Should I wash sweet potatoes before storing them?
Washing sweet potatoes before storing them is not recommended. Excess moisture can lead to mold and rot, reducing the shelf life of the sweet potatoes. Instead, gently brush off any dirt or debris from the surface of the sweet potatoes using a soft-bristled brush or a clean cloth. This will help remove any loose dirt without adding excess moisture.
It’s essential to handle sweet potatoes carefully to avoid damaging the skin, which can provide a pathway for bacteria and moisture to enter the potato. If the sweet potatoes are heavily soiled, it’s best to wash them just before using them. However, if you must wash them before storing, make sure to dry them thoroughly with a clean towel or paper towels to remove excess moisture.
How should I store sweet potatoes to keep them fresh?
Sweet potatoes should be stored in a cool, dark place with good ventilation. A temperature range of 55°F to 60°F (13°C to 15°C) is ideal for storing sweet potatoes. Avoid storing them in direct sunlight, near a heat source, or in areas with high humidity. You can store sweet potatoes in a paper bag, breathable container, or a ventilated plastic bag to maintain airflow.
It’s also essential to keep sweet potatoes away from strong-smelling foods, as they can absorb odors easily. Check on the sweet potatoes regularly to remove any that are spoiling, as this can affect the quality of the remaining potatoes. Proper storage can help extend the shelf life of sweet potatoes for several weeks to a few months.
Can I store sweet potatoes in the refrigerator?
Storing sweet potatoes in the refrigerator is not recommended, as the cold temperature can convert the starches in the potato to sugar, making them sweeter and softer. Additionally, the high humidity in the refrigerator can lead to mold and rot. If you must store sweet potatoes in the refrigerator, make sure to keep them away from direct moisture and check on them regularly.
However, if you live in a hot and humid climate, storing sweet potatoes in the refrigerator may be the best option. In this case, store them in a breathable container or paper bag to maintain airflow and keep them away from direct moisture. It’s essential to check on the sweet potatoes regularly to remove any that are spoiling.
How long can sweet potatoes be stored?
The shelf life of sweet potatoes depends on various factors, including the variety, storage conditions, and handling. Generally, sweet potatoes can be stored for several weeks to a few months when kept in a cool, dark place with good ventilation. Some varieties, like ‘Jewel’ and ‘Beauregard’, can be stored for up to 6 months, while others may only last for a few weeks.
It’s essential to check on the sweet potatoes regularly to remove any that are spoiling, as this can affect the quality of the remaining potatoes. If stored properly, sweet potatoes can maintain their quality and flavor for an extended period. However, it’s best to use them within a few weeks for optimal flavor and texture.
Can I store cooked sweet potatoes?
Cooked sweet potatoes can be stored in the refrigerator for up to 3 to 5 days. It’s essential to cool them down to room temperature before refrigerating them to prevent bacterial growth. Store cooked sweet potatoes in a covered container or plastic bag to maintain freshness.
Cooked sweet potatoes can also be frozen for up to 6 months. Let them cool down to room temperature, then transfer them to an airtight container or freezer bag. Frozen cooked sweet potatoes are perfect for using in soups, stews, or as a side dish. When reheating, make sure to heat them to an internal temperature of 165°F (74°C) to ensure food safety.
How do I know if a sweet potato has gone bad?
A sweet potato has gone bad if it shows signs of mold, rot, or soft spots. Check for any visible signs of mold or mildew, especially around the eyes or skin. If the sweet potato is soft to the touch or has a sour smell, it’s likely gone bad. Additionally, if the sweet potato has developed a greenish tint or has sprouted, it’s best to discard it.
It’s essential to inspect sweet potatoes regularly, especially if they’re stored for an extended period. Remove any spoiled sweet potatoes to prevent the spoilage from spreading to other potatoes. If you’re unsure whether a sweet potato is still good, it’s best to err on the side of caution and discard it to avoid foodborne illness.
Can I grow sweet potatoes at home?
Yes, you can grow sweet potatoes at home, provided you have a suitable climate and soil conditions. Sweet potatoes require a long growing season, typically 100 to 120 days, and prefer well-draining, loose soil with a pH between 5.5 and 6.5.
