Do I need to flip the sweet potato fries during cooking?

Flipping or shaking the sweet potato fries while cooking in the air fryer is a good idea. Flipping the fries helps ensure even cooking and browning on all sides, resulting in a crispy and delicious texture.

When air-frying sweet potato fries, it's recommended to shake the air fryer basket or flip the fries gently using tongs at the halfway point of the cooking time. This allows both sides of the fries to come into contact with the hot air, promoting even browning and preventing unevenly cooked spots.

Remember to be careful when flipping the fries, as they can be hot. Using tongs or a spatula can make the process easier and safer. Flipping the fries is a simple step that goes a long way toward achieving perfectly crispy and evenly cooked sweet potato fries in the air fryer. Enjoy your delightful and evenly-cooked fries!

Frequently asked questions:

Why do my sweet potato fries turn out soggy in an air fryer?

Due to several factors, sweet potato fries may turn out soggy in the air fryer. One common culprit is excess moisture on the surface of sweet potato fries. The retained water can hinder the crisping process if the fries are not patted dry before tossing them in oil. 

Additionally, overcrowding the air fryer basket can lead to poor air circulation, resulting in uneven cooking and sogginess. Preheating the air fryer is essential to achieving the desired crispiness, as it allows the fries to start cooking immediately upon insertion. 

Moreover, not flipping or shaking the fries during cooking can lead to uneven browning. It's crucial to follow the recommended cooking time and temperature for the specific model of your air fryer and ensure that the sweet potato fries are evenly coated with oil to promote crispiness.

Selecting high-quality sweet potatoes and maintaining a single layer of fries in the basket are essential to achieving perfectly crispy and delightful sweet potato fries in the air fryer.

Why do you soak sweet potatoes in water before air frying?

Soaking sweet potatoes in water before air frying is a technique used to remove excess starch and moisture from the surface of the fries. Removing the starch helps prevent the fries from sticking together and promotes better browning and crispiness during cooking.

When sweet potatoes are cut into fries, they release starch, which can cause them to become gummy or soggy if not properly removed. Soaking the fries in water helps to draw out some of this starch, resulting in crispier and more evenly cooked sweet potato fries.

To soak sweet potatoes, place the cut fries in a bowl of cold water and let them sit for about 30 minutes. After soaking, drain the water, and pat the sweet potato fries dry with a paper towel before tossing them in oil and air frying. This simple step can significantly improve the texture and taste of your air-fried sweet potato fries, making them even more enjoyable.

How long to soak sweet potatoes in water?

To achieve the best results, it is recommended to soak sweet potato fries in water for at least 30 minutes. Soaking for this duration allows enough time for the excess starch on the surface of the fries to be drawn out, which helps improve the crispiness during cooking.

However, if you have the time and want to maximize the benefits, you can soak the sweet potato fries for up to 2 hours. Longer soaking times can further enhance the texture and reduce the chances of the fries becoming soggy during air frying.

Remember that the exact soaking time may vary depending on the thickness of the fries and personal preference. The goal is to reduce the starch without causing the fries to become too soft.

After soaking, remember to drain the water and pat the fries dry with a paper towel before proceeding with the air frying process. This can make a significant difference in achieving perfectly crispy and delicious sweet potato fries.

How do I store leftover sweet potato fries?

To store leftover sweet potato fries, follow these steps:

  • Let the Fries Cool: Allow the sweet potato fries to cool to room temperature before storing them. Avoid storing hot fries in an airtight container, as the trapped steam can create excess moisture and make the fries soggy.
  • Use an Airtight Container: Transfer the cooled sweet potato fries into an airtight container. Ensure that the container is large enough to hold the fries without overcrowding.
  • Avoid Overlapping: Arrange the fries in a single layer inside the container, if possible. Overlapping the fries can cause them to stick together and lose their crispiness.
  • Refrigerate Promptly: Place the airtight container with the sweet potato fries in the refrigerator immediately after storing. Store them in the main part of the refrigerator, not the door, as the door can experience temperature fluctuations.
  • Keep Away from Moisture: Avoid placing additional moisture in the container, such as paper towels or condensation. Excess moisture can lead to sogginess.
  • Label and Date: If you anticipate keeping the sweet potato fries for more than a day, it's a good idea to label the container with the date. This way, you can keep track of their freshness.
  • Reheat Carefully: When ready to enjoy the leftover sweet potato fries, reheat them in an air fryer or oven. Please avoid using the microwave, as it can make the fries mushy.

While reheated sweet potato fries won't be as crispy as when freshly made, using an air fryer or oven can help revive some of their initial crispiness. Consume the leftovers within 2–3 days for the best quality and taste. Consume your delicious sweet potato fries, even the next day!
