Sweet potatoes are a beloved staple in kitchens around the world, cherished for their versatility, flavors, and nutritional benefits. However, when it comes to storing them, many home cooks frequently wonder: Can you put sweet potatoes in the refrigerator? This question is commonly posed, sparking numerous myths and misunderstandings about the best way to store these nutrient-packed tubers. In this article, we will delve into the science of sweet potato storage, explore the best practices, and provide tips to help you keep your sweet potatoes fresh, delicious, and nutritious.
The Nature of Sweet Potatoes
Before discussing storage methods, it’s important to understand what sweet potatoes are and how they can be affected by improper storage.
Understanding Sweet Potatoes
Sweet potatoes (Ipomoea batatas) are root vegetables and are distinct from white potatoes (Solanum tuberosum). Their natural sweetness, vibrant orange color, and nutritional richness are some of their most appealing characteristics. These tubers are:
- High in vitamins A and C
- Rich in dietary fiber
- Low in fat, making them a heart-healthy choice
- Versatile in cooking, suitable for baking, boiling, frying, and even grilling
Temperature Sensitivity of Sweet Potatoes
Sweet potatoes thrive in a specific temperature range. When exposed to too cold conditions, such as those found in refrigerators, the quality and taste can be compromised. Here are some key points to consider:
- Ideal Storage Temperature: Sweet potatoes prefer a temperature between 55°F to 60°F (13°C to 16°C).
- Cold Sensitivity: Storing sweet potatoes in a refrigerator (typically set at 35°F to 40°F or 1.6°C to 4.4°C) can lead to chilling injury, which can cause hard, cold-spotted textures and altered flavors.
Can You Refrigerate Sweet Potatoes?
The simple answer is: NO. Refrigerating sweet potatoes is not recommended; however, understanding the reasons behind this recommendation can help clarify why room temperature storage is best.
Effects of Refrigeration on Sweet Potatoes
Storing sweet potatoes in the refrigerator can cause several undesirable effects:

- Avoid Plastic Bags: Instead of sealing sweet potatoes in plastic bags, use breathable containers or paper bags that allow moisture to escape while preventing excessive humidity. This helps avoid rot and sprouting.
Identifying the Best Sweet Potatoes
When shopping for sweet potatoes, selecting the right quality enhances your culinary experience. Be on the lookout for:
Selecting Fresh Sweet Potatoes
Here are some tips for choosing the most fresh sweet potatoes during your grocery shopping:
- Skin Texture: Look for smooth, firm skin without blemishes, wrinkles, or dark spots.
- Size Consistency: Choose medium-sized sweet potatoes, as larger ones can sometimes become woody or less flavorful.
How to Store Cooked Sweet Potatoes
Once you’ve peeled, cooked, or prepared sweet potatoes in a dish, you may wonder about the best way to store them to maintain their flavor and texture.
Storing Cooked Sweet Potatoes
Cooked sweet potatoes can be stored effectively, but there are specific guidelines to consider:
- Cooling Properly: Allow cooked sweet potatoes to cool completely at room temperature (not more than two hours).
- Refrigeration: Unlike raw sweet potatoes, cooked sweet potatoes can be stored in the refrigerator. Place them in an airtight container; they will usually last for 3 to 5 days.
- Freezing: If you want to store them for longer, you can freeze cooked sweet potatoes. Cut them into portions, place them in airtight bags or containers, and they can last up to a year in the freezer.
Preparing for Long-Term Storage of Raw Sweet Potatoes
If you grow sweet potatoes or buy them in large quantities, consider preparing them for long-term storage.

Can you put sweet potatoes in the refrigerator?
Yes, you can put sweet potatoes in the refrigerator, but it’s not recommended as the cold temperature can negatively affect their texture and flavor. The ideal storage conditions for sweet potatoes are in a cool, dark, and well-ventilated place, such as a pantry or cellar. Refrigeration can cause the starches in sweet potatoes to convert to sugars more quickly, resulting in a sweeter taste and a grainy texture.
If you accidentally store them in the refrigerator, it’s best to consume them as soon as possible to avoid any further loss in quality. Cooked sweet potatoes can be safely stored in the refrigerator for a few days, but raw sweet potatoes will fare better when kept at room temperature away from humidity.
What happens to sweet potatoes when they are refrigerated?
When sweet potatoes are refrigerated, the cold environment leads to a process called “cold-induced sweetening.” This results in an increase in sugar levels, which can alter their natural flavor profile and make them taste overly sweet. Additionally, this process can also negatively impact the texture, causing them to become grainy and less palatable.
Moreover, prolonged exposure to cold temperatures can cause sweet potatoes to develop a hard center, which may not cook evenly. To maintain their best qualities, it is recommended to keep sweet potatoes in a consistent, room-temperature environment, away from direct sunlight and excessive moisture.
How should sweet potatoes be stored for optimal freshness?
For optimal freshness, sweet potatoes should be stored in a cool, dark, and dry location. A pantry, cellar, or a well-ventilated cupboard works best. They should be kept in a breathable container, such as a basket or a paper bag, to allow air circulation. Avoid storing them in plastic bags, as this can trap moisture and lead to spoilage.
It’s essential to check sweet potatoes regularly for any signs of sprouting or rotting. If you find any damaged or soft sweet potatoes, it’s best to remove them to prevent the spoilage from spreading to the others. By following these guidelines, you can extend the shelf life of your sweet potatoes and preserve their texture and flavor.
Can cooked sweet potatoes be refrigerated?
Yes, cooked sweet potatoes can be refrigerated. In fact, refrigerating them can help prolong their shelf life and keep them safe for consumption. To store cooked sweet potatoes, it’s best to let them cool to room temperature before placing them in an airtight container. This will help prevent moisture build-up, which can lead to spoilage.
Cooked sweet potatoes can typically be stored in the refrigerator for about three to five days. When you’re ready to eat them, you can reheat them in the microwave, oven, or stovetop. However, be mindful that reheating can sometimes change their texture, so proper storage is key to maintaining their quality.
What are some signs that sweet potatoes have gone bad?
There are several signs that indicate sweet potatoes have gone bad. The most common indicators include a mushy texture, a strong odor, and noticeable discoloration or dark spots on the skin. If you find any areas that are soft, shriveled, or rotten, it’s best to discard the entire sweet potato, as they may harbor harmful bacteria.
Sprouting is another sign of deterioration, although sprouted sweet potatoes can still be edible if stored properly. If the sprouts are small and the potato remains firm, you can cut off the sprouts and use the rest of the potato. However, if the sweet potato shows multiple signs of spoiling, it’s safest to throw it away to avoid any foodborne illnesses.
Are there any health risks associated with storing sweet potatoes in the refrigerator?
Storing sweet potatoes in the refrigerator primarily affects their quality rather than posing direct health risks. While the colder environment can lead to changes in texture and flavor, it does not render them harmful. However, if sweet potatoes spoil due to improper storage or if they develop mold, consuming them can indeed pose health risks.
To prevent health issues, it’s crucial to check stored sweet potatoes regularly and discard any that show signs of spoilage. Always err on the side of caution, and if you’re unsure about the quality of a sweet potato, it’s best to avoid consumption. Properly storing sweet potatoes in a cool, dry place will help minimize the chance of spoilage and ensure their safety for eating.
