Ingredients

  • 3 medium sweet potatoes

Steps

  1. Scrub the sweet potatoes and pat them dry.
  2. Put them in the basket, skins on, without overlapping.
  3. Air fry at 400°F (200°C) for 20 minutes, then turn them over.
  4. Cook for 20 more minutes, until a chopstick slides in easily.

Using an oven-style air fryer or a convection microwave on air fry? Spread food on a rack over a tray, and flip instead of shaking the basket.

What changes in oven-style air fry mode

How it varies by air fryer

Thickness can change the time by 10 minutes or more.

Tips

  • Halve very thick ones to cut the time.
  • Let them sit for 5 minutes after cooking; the inside gets even softer and sweeter.
  • Korean goguma (purple skin, pale yellow flesh) roasts especially well this way.

Troubleshooting

  • Hard skin, raw center: too short for the size. Add 10 minutes.
