Reheating Sweet Potatoes

Leftover potatoes can be easily reheated in different ways such as oven, microwave, stovetop, and air fryer. The right method ensures that the reheated sweet potato maintains its taste, texture, and quality. Find the best method that suits your needs.

Tip: The ideal internal temperature of the sweet potatoes is 210 degrees Fahrenheit.


To reheat sweet potatoes in the oven, the first step is to preheat them to 400 degrees Fahrenheit. Place the sweet potatoes on a baking sheet lined with foil or parchment paper or a crisper pan.

Reheat the sweet potatoes for 10 to 15 minutes. Make sure to flip them once during the reheating process for even heating. Some people like to cook them in a slow cooker but don’t forget to add water as this is the only way to make sure they don’t dry out.


Reheating sweet potatoes in the microwave oven on high heat is the fastest way and quickest method. Before microwaving, poke some holes in the sweet potato with a fork and place them on a microwave-safe plate.

You can also use a microwave-safe bowl to cook multiple potatoes at one time, increasing the time depending on the amount of potatoes.

Place it on a microwave-safe dish or plate and cover the sweet potato with wet paper towels or damp paper towel. This helps to trap steam while it reheats and ensures even heating. Microwave the sweet potato for 5 minutes, turning it halfway through.


You can also reheat sweet potatoes on the stovetop. Place the sweet potato pieces in a skillet over medium heat with olive oil for sauteed sweet potatoes.

If necessary, add a small amount of oil or butter to prevent sticking. Heat the sweet potatoes for 3-4 minutes, stirring occasionally.

Flip them over and heat for another 3-4 minutes or until warmed through. To cook them in a large pot, peel and chop the potatoes and then place them in salted boiling water for 20-25 minutes.

Air Fryer

Reheating sweet potatoes in an air fryer is another efficient method that doesn’t take too much time. Preheat your air fryer to 400 degrees Fahrenheit.

Place the sweet potatoes in the air fryer basket, avoiding overcrowding. Cook for about 10 to 15 minutes, flipping halfway through to ensure even heating.

Remember to choose the reheating method that best suits your needs and equipment availability. Each technique can effectively reheat sweet potatoes while preserving their taste and texture.

Toaster Oven

If you don’t have an air fryer, a toaster oven is another method and a good idea for cooking sweet potatoes compared to the microwave method. Adjust the rack to the low position, preheat it to 400 degrees, and press the bake setting.

Preparation and Storage

Storing Cooked Sweet Potatoes

Before storing cooked sweet potatoes, let them cool completely to prevent the growth of bacteria and food poisoning, which is a common cooking process for many other foods as well. Place the potatoes in an airtight container or wrap them individually in aluminum foil or plastic wrap.

Keep the container in the refrigerator, and make sure the temperature is set at or below 40 degrees Fahrenheit. Cooked sweet potatoes can remain in the fridge for up to four days.

If your dish contains mashed sweet potatoes, the easy way is to store them similarly by cooling them and placing them in an airtight container in the refrigerator.

For dishes like sweet potato fries or steamed sweet potatoes, it is crucial that you choose storage containers that can preserve their crispy or fluffy textures.

Freezing Sweet Potatoes

For longer-term storage, a great way to preserve sweet potatoes is by freezing them. Thoroughly wash and scrub the sweet potatoes, then boil them for 35 to 40 minutes until they are tender.

After boiling, drain, and let them cool completely. Once the whole potato is cooled, peel and slice the sweet potatoes.

The best way to arrange the slices is on an even layer of parchment paper-lined baking sheet. Cover and freeze overnight.

The next day, transfer the frozen slices to airtight storage containers or zip-top freezer bags and store them in the freezer for up to 12 months. This time frame is a long time compared to other foods. Make sure to monitor your potatoes over time to prevent freezer burn.

Thawing Sweet Potatoes

When you are ready to use the frozen sweet potatoes, remove them from the freezer and allow them to thaw in the refrigerator until they are soft.

The easiest way is to use the microwave defrost setting to thaw the sweet potatoes faster, but be cautious not to overcook them, as this can affect their texture.

Once thawed, you can use your sweet potatoes in various dishes like mashed potatoes, baked potatoes, or other sweet potato recipes.

Reheating Specific Dishes

In this section, we’ll discuss how to reheat different sweet potato dishes in a few simple steps for people learning how to reheat them for the first time, including sweet potato fries, baked sweet potatoes, mashed sweet potatoes, and sweet potato wedges.

Sweet Potato Fries

Reheating sweet potato fries can be done by baking them in the oven at 400°F for 10-15 minutes. Ensure they are spread out evenly on a baking tray lined with parchment paper to avoid overlapping.

Spritz the crispy sweet potato fries with oil and stir halfway through the cooking time to ensure even heating. This method helps retain their crispy texture and soft, fluffy centers.

Baked Sweet Potatoes

To reheat baked sweet potatoes, preheat the oven to 350°F. Wrap each individual baked potato in foil and place them on a baking tray, puncture the foil once or twice to allow steam to escape. Heat the potatoes for 15-20 minutes or until warmed throughout. This method maintains their nutritious quality and ensures they don’t dry out.

Mashed Sweet Potatoes

Reheating mashed sweet potatoes can be done on the stovetop. Place the sweet potato mash in a saucepan, and heat over low-medium heat, stirring occasionally to prevent sticking. If the mixture seems too thick, add a splash of milk or a small amount of butter to adjust the consistency.

Be sure to heat the leftover sweet potatoes thoroughly for an even temperature and taste. This method is suitable for reheating small batches and helps to preserve texture and flavor.

Sweet Potato Wedges

For reheating sweet potato wedges, preheat the oven to 400°F. Spread the wedges evenly on a baking tray lined with parchment paper, making sure there’s no overlap.

Drizzle with a small amount of oil or seasoning if desired, then roast the wedges in the oven for 10-12 minutes, or until hot and crisp. This method retains the flavor and texture, making leftovers just as enjoyable as freshly cooked wedges.
