Sweet potatoes are a delicious and nutritious addition to any meal, but like any other food, they can go bad if not stored or cooked properly. If you’re unsure whether your cooked sweet potatoes are still safe to eat, you’re not alone. In this article, we’ll explore the signs of spoilage, the risks of eating bad sweet potatoes, and provide you with some valuable tips on how to store and reheat your cooked sweet potatoes to keep them fresh for longer.
Signs of Spoilage in Cooked Sweet Potatoes
Cooked sweet potatoes can go bad if they’re not stored properly, and there are several signs you can look out for to determine if they’re still safe to eat. Here are some of the most common signs of spoilage:
Visual Signs
- Slime or Mold: Check your cooked sweet potatoes for any visible signs of slime or mold. If you notice any white, green, or black patches, it’s best to err on the side of caution and discard them.
- Discoloration: Cooked sweet potatoes should have a uniform color. If they’ve turned gray, green, or black, it may be a sign of spoilage.
- Soft or Mushy Texture: Cooked sweet potatoes should be soft, but still firm to the touch. If they’re mushy or soft to the point of being unappetizing, it’s likely they’ve gone bad.
Smell and Taste
- Off Smell: Cooked sweet potatoes should have a sweet, earthy smell. If they smell sour, bitter, or unpleasantly sweet, it’s a sign of spoilage.
- Off Taste: If your cooked sweet potatoes taste sour, bitter, or unpleasantly sweet, it’s best to discard them.
Other Signs
- Temperature: Cooked sweet potatoes should be stored in the refrigerator at a temperature of 40°F (4°C) or below. If they’ve been left at room temperature for too long, they may have entered the danger zone, which is between 40°F and 140°F (4°C and 60°C).
- Time: Cooked sweet potatoes can be safely stored in the refrigerator for 3 to 5 days. If they’ve been stored for longer than that, it’s best to err on the side of caution and discard them.

How Long Does Cooked Sweet Potato Last in the Fridge?
Cooked sweet potatoes can last for 3 to 5 days in the fridge, depending on how they are stored. It’s essential to cool the sweet potatoes to room temperature within two hours of cooking to prevent bacterial growth. Once cooled, place them in a covered, airtight container and refrigerate at a temperature of 40°F (4°C) or below.
When storing cooked sweet potatoes in the fridge, make sure to check on them regularly for any signs of spoilage. If you notice any mold, sliminess, or an off smell, it’s best to err on the side of caution and discard the sweet potatoes. Even if they look fine, cooked sweet potatoes that have been in the fridge for more than 5 days may not be safe to eat.
Can You Freeze Cooked Sweet Potatoes?
Yes, cooked sweet potatoes can be frozen to extend their shelf life. In fact, freezing is an excellent way to preserve cooked sweet potatoes for several months. To freeze cooked sweet potatoes, let them cool to room temperature, then place them in airtight containers or freezer bags, making sure to remove as much air as possible before sealing.
When you’re ready to eat the frozen sweet potatoes, simply thaw them overnight in the fridge or reheat them in the microwave or oven. Frozen cooked sweet potatoes are perfect for meal prep, as they can be easily reheated and added to a variety of dishes. Just be aware that freezing may affect the texture of the sweet potatoes, making them slightly softer.
What Are the Signs of Spoilage in Cooked Sweet Potatoes?
There are several signs to look out for to determine if cooked sweet potatoes have gone bad. One of the most obvious signs is an off smell, which can range from a sour or unpleasantly sweet odor to a strong, pungent smell. Another sign is the presence of mold or slime on the surface of the sweet potatoes.
Other signs of spoilage include a slimy or soft texture, which can indicate that the sweet potatoes have developed bacteria or other microorganisms. If you notice any of these signs, it’s best to discard the sweet potatoes immediately to avoid foodborne illness. Remember, when in doubt, it’s always better to err on the side of caution.
Can You Reheat Cooked Sweet Potatoes Safely?
Yes, cooked sweet potatoes can be reheated safely, as long as they are reheated to an internal temperature of at least 165°F (74°C). This is especially important if you’re reheating sweet potatoes that have been stored in the fridge or freezer for several days.
When reheating cooked sweet potatoes, make sure to use a food thermometer to check the internal temperature. You can reheat them in the microwave, oven, or on the stovetop, but be aware that overheating can cause the sweet potatoes to dry out or become unappetizing. To avoid this, reheat them gently and add a splash of water or broth if necessary to maintain moisture.
How Do You Store Cooked Sweet Potatoes at Room Temperature?
It’s generally not recommended to store cooked sweet potatoes at room temperature for extended periods, as this can allow bacteria to grow and cause foodborne illness. However, if you need to store cooked sweet potatoes at room temperature for a short period, make sure to keep them in a covered, airtight container and consume them within a few hours.
If you’re storing cooked sweet potatoes at room temperature, keep them away from direct sunlight and heat sources, and make sure the room is at a comfortable temperature (around 70°F to 75°F or 21°C to 24°C). Never leave cooked sweet potatoes at room temperature for more than 2 hours, as this can allow bacteria to multiply rapidly.
Can You Eat Cooked Sweet Potatoes That Have Been Left Out Overnight?
No, it’s not recommended to eat cooked sweet potatoes that have been left out overnight. Cooked sweet potatoes that have been left at room temperature for more than 2 hours can develop bacteria, such as Staphylococcus aureus, Salmonella, and Clostridium perfringens, which can cause foodborne illness.
Even if the sweet potatoes look and smell fine, it’s best to err on the side of caution and discard them. Foodborne illness can be severe, especially for vulnerable populations such as the elderly, young children, and people with weakened immune systems. To avoid the risk of foodborne illness, always refrigerate or freeze cooked sweet potatoes promptly and consume them within a few days.
Can You Use Cooked Sweet Potatoes That Have Been Frozen for Several Months?
Yes, cooked sweet potatoes that have been frozen for several months can still be safe to eat, as long as they have been stored properly in airtight containers or freezer bags. Frozen cooked sweet potatoes can be safely stored for 6 to 8 months, although the quality may decrease over time.
When you’re ready to eat frozen cooked sweet potatoes, simply thaw them overnight in the fridge or reheat them in the microwave or oven. Before consuming, always check the sweet potatoes for any signs of spoilage, such as off smells or slimy textures. If they look and smell fine, they should be safe to eat.
