Best Air Fryer Sweet Potato Recipe

5 from 1 vote

These air fryer sweet potatoes take only 10 minutes to cook, are extremely versatile (I love them on salads or a even a breakfast side!), require no pre-soaking, and are a less-mess recipe with easy cleanup. After lots of taste testing, I discovered a little sprinkle of cornstarch gives these sweet potatoes a crispier exterior while still having that tender, sweet inside and makes these air fryer sweet potatoes a family favorite!

Then cut it lengthwise and then horizontally (see photos). Cut into 1 inch cubes. If possible, try to cut them as uniformly as possible for even cooking.
Toss with spices: In a large bowl, toss your cubes with the oil, cornstarch, and spices.
1 1/2 tbsp oil of choice, 1 tsp cornstarch or arrowroot powder, 1 tsp garlic powder, 1 tsp smoked paprika, 1/2 tsp salt, 1/4 tsp black pepper
Air fry: Spread your cubes evenly in the air fryer basket. If you have a small air fryer, consider doing two batches to obtain optimal crispiness.
Air fry for 8-10 minutes, giving it a gentle shake halfway through, until your cubes are tender to your liking (use a fork to pierce a sweet potato to check tenderness).
*Every air fryer is a little different, so your cooking time may vary slightly.
Enjoy!

Notes

Why preheat the air fryer?

By warming the air fryer before use, this will speed up our cooking time. FYI this is not necessary but saves time cooking!

Cut the sweet potato ends off first, then cut lengthwise to create a stable surface (see photos above).
