Sweet potatoes are a staple in many cuisines around the world, and their popularity continues to grow due to their rich nutritional profile and versatility in various dishes. However, when it comes to storing sweet potatoes, many people are unsure whether they can be refrigerated before cooking. In this article, we will delve into the world of sweet potatoes and explore the best ways to store them, including refrigeration.
Understanding Sweet Potatoes
Before we dive into the storage methods, it’s essential to understand the characteristics of sweet potatoes. Sweet potatoes are a type of root vegetable that belongs to the morning glory family. They are native to the Americas and are now grown in many parts of the world. Sweet potatoes are rich in complex carbohydrates, fiber, vitamins, and minerals, making them an excellent addition to a healthy diet.
Types of Sweet Potatoes
There are several types of sweet potatoes, each with its unique characteristics and storage requirements. Some of the most common types of sweet potatoes include:
- Jewel sweet potatoes: These are one of the most widely available types of sweet potatoes and are known for their sweet, nutty flavor.
- Beauregard sweet potatoes: These sweet potatoes have a slightly sweet and earthy flavor and are often used in baked goods.
- Okinawan sweet potatoes: These sweet potatoes have a sweet, purple flesh and are often used in Japanese cuisine.
Storing Sweet Potatoes
Sweet potatoes can be stored in various ways, depending on the desired storage period and the type of sweet potato. Here are some common methods for storing sweet potatoes:
Room Temperature Storage
Sweet potatoes can be stored at room temperature for a short period, typically up to a week. They should be kept in a cool, dry place, away from direct sunlight and heat sources. It’s essential to check on the sweet potatoes regularly to ensure they are not developing any signs of spoilage, such as mold or soft spots.
Refrigeration
Refrigerating sweet potatoes is a common practice, but it’s essential to do it correctly to maintain their quality. Sweet potatoes should be stored in a breathable bag or container to maintain airflow and prevent moisture buildup. They should be kept in the crisper drawer of the refrigerator, where the temperature is typically around 40°F (4°C).
However, refrigerating sweet potatoes can affect their texture and flavor. The cold temperature can convert the starches in the sweet potatoes into sugars, making them sweeter but also softer. This process is called “cold-induced sweetening.” Additionally, refrigeration can cause the sweet potatoes to develop a less appealing flavor and texture.
Freezing
Freezing is an excellent way to store sweet potatoes for an extended period. Cooked or raw sweet potatoes can be frozen, but it’s essential to follow proper freezing procedures to maintain their quality. Sweet potatoes should be washed, peeled, and chopped or sliced before freezing. They can be frozen in airtight containers or freezer bags, making sure to remove as much air as possible before sealing.
Frozen sweet potatoes can be stored for up to 12 months. When you’re ready to use them, simply thaw them in the refrigerator or reheat them in the oven or microwave.
Can You Refrigerate Sweet Potatoes Before Cooking?
Now that we’ve explored the different storage methods for sweet potatoes, let’s answer the question: can you refrigerate sweet potatoes before cooking? The answer is yes, but with some caveats.
Refrigerating sweet potatoes before cooking can affect their texture and flavor, as mentioned earlier. However, if you plan to cook the sweet potatoes within a few days, refrigeration can be a convenient way to store them.
Here are some tips for refrigerating sweet potatoes before cooking:
- Store them in a breathable bag or container: This will help maintain airflow and prevent moisture buildup.
- Keep them in the crisper drawer: This will help maintain a consistent temperature and humidity level.
- Use them within a few days: Refrigerated sweet potatoes are best used within 3-5 days.
- Cook them properly: Cooking the sweet potatoes properly can help restore their texture and flavor.
Cooking Methods for Refrigerated Sweet Potatoes
When cooking refrigerated sweet potatoes, it’s essential to use the right cooking method to restore their texture and flavor. Here are some cooking methods that work well for refrigerated sweet potatoes:
- Baking: Baking is an excellent way to cook refrigerated sweet potatoes. Simply preheat your oven to 400°F (200°C), poke some holes in the sweet potatoes, and bake for 45-60 minutes, or until they’re tender.
- Boiling: Boiling is another great way to cook refrigerated sweet potatoes. Simply place them in a pot of salted water, bring to a boil, and cook for 10-15 minutes, or until they’re tender.
- Roasting: Roasting is a delicious way to cook refrigerated sweet potatoes. Simply preheat your oven to 425°F (220°C), chop the sweet potatoes into wedges or cubes, and roast for 20-30 minutes, or until they’re tender and caramelized.
Conclusion
In conclusion, refrigerating sweet potatoes before cooking is possible, but it’s essential to follow proper storage and cooking procedures to maintain their quality. By storing sweet potatoes in a breathable bag or container, keeping them in the crisper drawer, and using them within a few days, you can enjoy delicious and nutritious sweet potatoes all year round.

It’s also important to note that refrigeration will not stop the sweet potatoes from eventually spoiling. They should be used within a few days of purchase.
How should sweet potatoes be stored before cooking?
Sweet potatoes should be stored in a cool, dark place with good ventilation. A pantry or cupboard is a good place to store sweet potatoes. They should be kept away from direct sunlight and heat sources. It’s also important to keep them away from other fruits and vegetables that release ethylene gas, as this can cause the sweet potatoes to ripen more quickly.
A paper bag or breathable container is a good way to store sweet potatoes. This will allow for airflow and help to keep the sweet potatoes dry. Do not wash the sweet potatoes before storing them. Excess moisture can cause the sweet potatoes to rot.
What happens if you refrigerate sweet potatoes for too long?
Refrigerating sweet potatoes for too long can cause a process called “chill injury.” This can affect the texture and flavor of the sweet potatoes. Chill injury can cause the sweet potatoes to become soft and mushy. It can also cause the formation of off-flavors and aromas.
In addition to chill injury, refrigerating sweet potatoes for too long can also cause them to rot. This is because the cold temperature and high humidity of the refrigerator can cause the sweet potatoes to become too moist. This can lead to the growth of mold and bacteria, which can cause the sweet potatoes to spoil.
Can you freeze sweet potatoes before cooking?
Yes, sweet potatoes can be frozen before cooking. Freezing is a good way to preserve sweet potatoes for long-term storage. To freeze sweet potatoes, they should be cooked and then mashed or pureed. They can then be placed in an airtight container or freezer bag and stored in the freezer.
Frozen sweet potatoes can be used in a variety of dishes, such as soups, stews, and casseroles. They can also be used as a side dish, similar to mashed potatoes. When using frozen sweet potatoes, it’s best to thaw them first and then reheat them.
How long can sweet potatoes be stored before cooking?
The length of time that sweet potatoes can be stored before cooking depends on the storage conditions. If stored in a cool, dark place with good ventilation, sweet potatoes can last for several weeks. If stored in the refrigerator, they can last for up to a week.
It’s also important to note that the variety of sweet potato can affect its storage life. Some varieties, such as the ‘Jewel’ and ‘Beauregard’, have a longer storage life than others. In general, it’s best to use sweet potatoes within a week or two of purchase for optimal flavor and texture.
