Equipment

Ingredients

  • Preheat the air fryer at 400°F for 2 minutes. Spread the seasoned sweet potatoes in the fryer tray, in a single layer. You may have to cook these in 2 batches, depending on the size of your air fryer.

  • Air fryer for 10-12 minutes, shaking the basket halfway through, about 5-6 minutes. Remove and check the sweet potatoes. For extra crispy, shake the basket and air fry for another 2 minutes.

Notes

  • Use a sharp knife when cutting: A dull knife means you'll end up pressing harder to cut, which requires more effort and is more likely to slip and cut you.
  • Cut them the same size: This ensures even cooking. To get a consistent size, I start by making cut marks that are ½ inch apart and then cut them through.
  • Make them crispy: Make sure to spread the sweet potatoes in a single layer when cooking them, even if you have to make multiple batches.
  • Shake the basket halfway: Don't neglect to shake the basket halfway through the cooking time to allow all the edges of each cube to be cooked evenly.
  • Serve them immediately: These roasted sweet potatoes get soft and lose their crispness as they cool, so I find it best to serve them immediately!
