Boiled sweet potatoes can stay fresh in the fridge for 3-5 days when stored properly in an airtight container.
Boiled sweet potatoes, like most cooked foods, are susceptible to bacterial growth if not stored correctly. After boiling, allow the sweet potatoes to cool completely at room temperature. This usually takes about an hour.
Cooling them before refrigeration prevents condensation from forming inside the container, which can accelerate spoilage. Once cooled, place the sweet potatoes in an airtight container. This helps to prevent them from drying out and also minimizes exposure to bacteria and odors in the refrigerator.
Store the container in the refrigerator at a temperature of 40°F (4°C) or below. Properly stored, boiled sweet potatoes should remain safe to eat for 3 to 5 days.
Note: Always check for signs of spoilage before consuming, such as a slimy texture, unusual odor, or discoloration. If you notice any of these signs, discard the sweet potatoes immediately.
To maximize the shelf life of your boiled sweet potatoes, avoid adding any seasonings or sauces before storing them. Add these just before reheating and serving, as they can sometimes promote bacterial growth.
