What You'll Learn
Preheat the air fryer
Preheating your air fryer is a crucial step in ensuring your sweet potato fries cook accurately at the temperature you select. While some air fryers do not recommend preheating, most do, and even those that don't will benefit from it. Preheat your air fryer to a temperature of around 380°F. If you are using frozen sweet potato fries, you can preheat to a slightly lower temperature of 360°F.
When preparing your sweet potatoes, cut off either end and cut the sweet potato into long 1/4-inch thick spears. If you have smaller pieces, set them aside so you can cook them for a shorter time in a separate batch. You can also cut the fries into thinner slices, around 1/4-inch to 1/2-inch thick, to make them crispier. Try to cut the fries to a uniform size for even cooking, as they will shrink slightly when cooked.
Before cooking, soak your sweet potato fries in a bowl of cold water with ice cubes for 30 minutes to an hour. This will help remove excess starch, giving the fries a fluffier middle while remaining crispy on the outside. After soaking, drain and pat the fries completely dry with a kitchen towel. If you have time, let them air dry.
Now your sweet potatoes are ready for the air fryer. Drizzle oil over the fries and toss to combine in a large bowl. Be careful not to use too much oil, as this can make the fries soggy. You can also add seasoning at this stage, but be sure not to add salt, as this can draw out moisture and make the fries soft.

Peel and cut sweet potatoes
To peel and cut sweet potatoes, start by choosing two medium-sized sweet potatoes that are not too long. This way, you can use the full length of the potatoes as the length of the fry. Remember that sweet potatoes shrink after cooking, so look for a shape slightly longer than the ideal fry length.
Next, peel the sweet potatoes and cut off the skinny ends. You can save the ends for a different recipe. Then, cut the sweet potatoes in half lengthwise. This will make it easier to lay them flat on a cutting board and start cutting them into long slices. The thinner you cut them, the crispier they will be. It is recommended to cut them into 1/4-inch to 1/2-inch thick slices.
If you have the time, you can further enhance the crispiness of your sweet potato fries by soaking them in a large bowl of cold water with ice cubes for 30 minutes to an hour, or even overnight. This step helps remove excess starch, resulting in a fluffier middle and crispier exterior. After soaking, be sure to thoroughly pat the potatoes dry before placing them in the air fryer.

Soak potatoes in water
Soaking potatoes in water is an important step in achieving crispy sweet potato fries. It helps to remove some of the starch present in potatoes, which can prevent them from sticking together and result in a crispier texture.
To soak potatoes, start by peeling and slicing the sweet potatoes into the desired fry shape and thickness. The recommended thickness for sweet potato fries is around 1/4 to 1/2-inch thick. Once you have cut your potatoes, submerge them in a large bowl of cold or hot tap water for at least 20 minutes. You can also add a tablespoon of vinegar to the water, as some suggest. Soaking the potatoes for longer, or even overnight in the refrigerator, is also an option if you want to prepare them ahead of time.
After soaking, it is crucial to thoroughly dry the potatoes. Spread them out on paper towels or a lint-free dish towel and pat them completely dry. Wet potatoes will not crisp up as well in the air fryer. Once dry, you can proceed to the next steps of tossing them with oil, salt, and any desired seasonings, and air-frying them to golden brown perfection!
While the soaking step is not mandatory, it can significantly improve the texture and crispiness of your sweet potato fries. It is worth the extra time and effort to ensure your fries turn out perfectly.

Oil and seasoning
When making sweet potato fries in an air fryer, you only need a small amount of oil. You can use any oil you like, but it's recommended to go for a high smoke point oil, such as avocado oil or canola oil. You can also use cooking spray.
Before adding oil, it's important to prepare the sweet potatoes. First, wash and peel the sweet potatoes. Then, cut off either end and cut the sweet potato into long 1/4-inch thick spears. Look for sweet potatoes that are not too long, so you can use the full length of the potato as the length of the fry. The thinner you cut them, the crispier they will be. You can also "square off" the pointy tips to prevent burning.
Next, soak the raw sweet potato fries in a large bowl of cold water with ice cubes for at least 30 minutes, or overnight if you have the time. This removes excess starch and gives the fries a fluffier middle while staying crispy on the outside. After soaking, drain and rinse the sweet potatoes, and pat them dry with a kitchen towel.
Now, you can add the oil. Drizzle oil over the fries and toss them in a large bowl to combine. Be careful not to use too much oil, as this can make the fries soggy. You can also add a tablespoon of cornstarch to make them crispier.
Finally, season the fries. In a small bowl, combine the seasoning ingredients and then sprinkle them over the oil-coated fries. Toss the slices to evenly coat them in seasoning. You can season with salt, pepper, smoked paprika, and arrowroot starch, or any other seasonings you like. However, it's best to add salt after air frying, as it can draw moisture out of the fries and make them too soft.

Reheating and storing
Reheating sweet potato fries in an air fryer is a great way to restore their crispy texture and delicious flavor. It's quick and easy, and you can avoid soggy fries altogether! Here's how to do it:
Firstly, preheat your air fryer. Different sources recommend preheating to different temperatures, such as 375°F (190°C) or 400°F (200°C). The duration of the preheating also varies, with suggestions ranging from 3-5 minutes to 5 minutes.
Next, prepare your fries. If they are frozen, increase the cooking time to around 7-10 minutes. If they are leftover, room-temperature fries, you can spritz or toss them with a bit of oil to help them crisp up. However, this is not necessary, and some sources suggest reheating without any additional oil. You can also add extra seasoning before cooking, but this is optional.
Now, arrange the fries in the air fryer basket. Avoid overcrowding the basket to ensure even heating. If you have a large quantity of fries, it might be best to reheat them in batches.
Finally, set the cook time and temperature. Most sources recommend reheating at 350°F (175°C) for 3-5 minutes, shaking the basket halfway through. However, one source suggests a higher temperature of 400°F (200°C) and a cooking time of 4-6 minutes, also shaking the basket halfway. Keep in mind that cooking time may vary depending on the thickness of your fries and the model of your air fryer, so be sure to check on them frequently to prevent overcooking and ensure they reach your desired level of crispiness.
In addition to reheating, it's important to know how to store your sweet potato fries properly. While I wasn't able to find specific information on storing air-fried sweet potato fries, here are some general guidelines for storing cooked sweet potatoes:
Cooked sweet potatoes can be stored in the refrigerator for 3-5 days or in the freezer for up to 2 months. Make sure to store them in an airtight container to prevent them from drying out or absorbing odors from other foods.
