3-Step Execution Protocol

Preheat & Prep

Preheat air-fryer to 390°F (199°C). Place sweet potatoes (whole, medium) (8-10 oz medium sweet potatoes, scrubbed, pierced multiple times with paring knife) in a single layer with space between items for convection airflow. Spray lightly with high-smoke-point oil.

Cook & Flip

Cook for 40–45 mins. Flip or shake basket at the 20-minute mark for even browning.

Check & Rest

Skin puffs slightly and caramelizes around vent holes; paring knife slides into center with zero resistance. Confirm internal temperature reaches 205°F–210°F (96°C–99°C) internal. Rest for 5 minutes before serving.

Pro Tip: Piercing deeply is essential to prevent pressure buildup and allow natural sugars to seep and blister into sticky caramel spots.
