How to cook sweet potatoes in air fryer cubes?

Start by washing and cubing your sweet potatoes into ½ to ¾ inch pieces. Soak them in cold water for 20 minutes to remove starch, then dry well. Toss with a bit of oil and seasoning, then cook in a preheated air fryer at 400°F for 12–16 minutes, shaking the basket halfway through. Keep the cubes in a single layer for even crisping.

For cubed sweet potatoes, it takes about 12 to 16 minutes at 400°F. The exact time depends on the size of your cubes and your air fryer model. You’ll know they’re done when the outside is crispy and a fork slides in easily.

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

Soaking air fryer sweet potato cubes in water helps remove excess starch. This step is key for getting them crispy on the outside instead of soft or soggy. Just 20 to 30 minutes in cold water can make a noticeable difference.

Why are my sweet potatoes not crispy in air fryer?

If your air fryer sweet potato cubes aren’t crispy, it’s likely due to one of three things: too much oil, overcrowding the basket, or not drying the cubes properly after soaking. Also, check your temperature—400°F works best for that crispy finish. A second shake mid-cook also helps all sides brown evenly.
