How to prepare sweet potatoes for air frying
Preparing sweet potatoes for air frying is a simple process. First, select sweet potatoes that have a smooth, deep orange-tan skin and feel heavy for their size. Wash the sweet potatoes thoroughly, and decide whether or not to peel them—peeling is optional. Next, cut the sweet potatoes into equal-sized cubes or chunks of around 1/2-inch thickness. This ensures that the sweet potatoes cook evenly and at the same time.
Once cut, transfer the sweet potato cubes to a mixing bowl. Now, you can add your choice of oil and seasonings. You can use olive oil, avocado oil, or melted butter. For seasonings, you can try a blend of harissa, garlic powder, salt, pepper, and even a little sugar or maple syrup. You can also experiment with spices like turmeric, cumin, cayenne pepper, ginger, or garam masala. Toss the sweet potato cubes well to ensure they are evenly coated with oil and seasonings.
After the sweet potatoes are seasoned, preheat your air fryer according to the manufacturer's instructions. Many recipes recommend preheating the air fryer to 400°F (200°C). If your air fryer has a preheat setting, it will remind you to add the food after preheating. Place the sweet potato cubes in a single layer in the air fryer basket. Avoid overcrowding the basket, as this can affect cooking time and evenness. If you have a smaller air fryer, you may need to cook the sweet potatoes in batches.
Now, you are ready to air fry your sweet potatoes! The cooking time will depend on the size of your sweet potato cubes and your desired level of doneness. For 1/2-inch cubes, air fry for around 10 minutes at 400°F, shaking the basket or stirring the sweet potatoes halfway through. If you prefer a crispier texture, add a couple of extra minutes. For whole sweet potatoes, the cooking time will be significantly longer, typically ranging from 40 to 60 minutes at 375°F, or until tender when pierced with a fork.

Air fryer temperature and timing
The temperature and timing for cooking sweet potatoes in an air fryer depend on the size of the potato and the quantity being cooked. Medium-sized sweet potatoes typically take 40 to 55 minutes to cook in an air fryer at 375°F to 400°F. Smaller potatoes may take around 35 minutes, while larger potatoes may take 50 minutes or more. It is important to ensure that the sweet potatoes are in a single layer in the air fryer basket and not overcrowded, as this will increase the cooking time and prevent even cooking.
When cooking sweet potato cubes in an air fryer, the temperature and timing will differ from cooking whole potatoes. Sweet potato cubes should be cooked at 400°F for 10 minutes, shaking the basket halfway through. If you are cooking a double batch or using a smaller air fryer, the second batch may take less time as the air fryer will already be hot.
It is worth noting that not all air fryer brands require preheating. However, it is recommended to preheat the air fryer according to the manufacturer's instructions to ensure even and thorough cooking. Additionally, some air fryers have a reheat button, which can be used to reheat cooked sweet potatoes.
The cooking time for sweet potatoes in an air fryer can be adjusted to achieve the desired texture. For a crispier texture, the cooking time can be extended by a few minutes. On the other hand, for a softer texture, the potatoes can be cooked for a shorter duration.

Reheating sweet potatoes in an air fryer
When it comes to reheating, the air fryer should be heated to 350°F. The sweet potatoes should be placed in a single layer in the air fryer basket, with a gap between each potato to avoid overcrowding. Reheating will take around 5–10 minutes, or until the potatoes are warmed through. If you are reheating a large batch, it may be necessary to do so in batches to ensure even heating.
For sweet potatoes that have been cut into cubes, a similar process can be followed. Reheat in the air fryer at 300°F for 7–8 minutes, or until they are as good as fresh. Again, ensure that the cubes are spread out in a single layer and are not overcrowded.
It is worth noting that the reheating time may vary depending on the size and model of your air fryer, so adjustments may be necessary. Additionally, you can also reheat sweet potatoes in the microwave for 1-minute bursts until they are warmed through.

Seasoning and toppings
A simple seasoning can be made with olive oil or avocado oil, garlic powder, salt, and pepper. Toss the sweet potato cubes in this mixture until they are well coated. You can also add paprika or chilli powder for a spicy kick. Other basic seasonings include turmeric, cumin, and garam masala.
For a sweeter option, you can add cinnamon, brown sugar, or maple syrup to your sweet potatoes. Cinnamon is a great choice if you plan on adding them to oatmeal. You can also top your sweet potatoes with butter, sour cream, or cheese for a savoury, creamy flavour.
If you're feeling adventurous, try something like pecans, mini marshmallows, or even chilli lime seasoning. You can also stuff your sweet potatoes with different fillings. Some ideas include chicken enchilada, vegetarian, or Italian-stuffed sweet potatoes.
Remember, the beauty of seasoning and toppings is that you can customise them to your taste preferences and get creative with different combinations.

Sweet potato varieties
Sweet potatoes are incredibly versatile, but the variety you choose will impact the cooking method and the flavor of the dish. While some sweet potatoes are dense, starchy, and creamy, others are more watery when cooked, with a stringier texture.
The most common varieties in the US are the Beauregard, the jewel, and the garnet (also known as red yams). The Beauregard is the most widely grown commercial cultivar, with a dusky red skin and orange flesh. It is a versatile variety that lends itself to baking, boiling, mashing, or frying. The jewel sweet potato, with its copper skin and deep-orange flesh, is probably what you think of when you think of a sweet potato. It is traditionally used for baking and casseroles, especially during the holidays. Garnets, named for their red-purple skin, have orange flesh that is moist and heavy when baked.
Other varieties include the Red Garnet, which is a little less sweet than the Beauregard, and the Japanese variety, which is available in the US. The Purple Splendor has a dry texture and is moderately sweet, while the Purple Majesty has elliptic, uniform shapes and is well adapted to sandy soils. The Carolina Ruby has a deep red skin and a moist, sweet flavor when baked. The Covington is the major table stock cultivar in North Carolina, with a high yield and a good packout of No.1-sized roots. The Nugget sweet potato has rosy skin and light orange flesh that is dense and holds its shape when cooked, making it excellent for roasting and glazing. The Amish Bush Porto Rico variety has a bushy cluster shape, with rosy skin and orange flesh that bakes up buttery and lush. The O'Henry has cream-colored flesh that is lightly sweet, dense, and heavy when baked.
There are also sweet potatoes, such as the Hannah variety, that do not have an orange interior. The speckled purple sweet potato has magenta-flecked flesh and a mild, nutty flavor. It remains firm when boiled or fried. The Envy is an heirloom variety with pale orange skin and flesh, and is mild, moist, and sweet, making it a good choice for baking, roasting, and casseroles. The Korean purple is an Asian heirloom variety with speckled purple skin and white flesh, and a chestnut-like flavor when baked or boiled. The Okinawa sweet potato has tan skin and sugary magenta flesh that holds its shape well across various cooking methods.
