The cooking time for sweet potatoes in an air fryer depends on the size and cut of the potatoes. For whole medium-sized sweet potatoes, the typical cooking time is about 40 to 55 minutes at 375°F to 400°F until they are fork- tender. Smaller sweet potatoes can take around 35 minutes, while larger ones may require 50 minutes or more. It is important to poke holes in the potatoes before cooking and to avoid overcrowding the air fryer basket to ensure even cooking. If the sweet potatoes are cut into wedges, cubes, or fries, the cooking time is shorter—usually about 10 to 20 minutes at around 390°F, turning or shaking the pieces every 5 to 7 minutes for even crisping and cooking. Summary:

• Whole medium sweet potatoes: 40 to 55 minutes at 375°F to 400°F
• Smaller potatoes: around 35 minutes
• Larger potatoes: 50 minutes or more
• Cut pieces (wedges, cubes, fries): 10 to 20 minutes at about 390°F, turning halfway through
• Pierce whole potatoes with a fork before cooking
• Do not wrap in foil and avoid overcrowding

These guidelines ensure sweet potatoes come out with fluffy insides and lightly crisp skin in the air fryer.
