Whole Russet Baked Potato in Air Fryer: 375°F (190°C) for 40 Minutes
Cook whole russet baked potato in an air fryer at 375°F (190°C) for 40 minutes instead of 400°F for 55 minutes in a conventional oven, shaking or turning halfway through cooking until tender when pierced with knife or 205°f–210°f (96°c–99°c) internal temp.
Oven baked potatoes take 55–60 minutes at 400°F, but cook in just 35–40 minutes at 375°F in the air fryer. Rub skin with olive oil and coarse kosher salt for a glassy, chip-like crunch.
Larger cavity requires longer preheat and slower surface moisture evaporation.
Midpoint (20 min): Turn potatoes halfway through at 20 minutes for even crisping on all sides

Frequently Asked Questions
Do you wrap baked potatoes in foil in the air fryer? ▾
Never wrap potatoes in foil in an air fryer; foil traps steam and makes skins soggy. Cook bare with oil and coarse salt for crispy skins.
What temperature indicates a fully baked potato? ▾
A potato is fully baked and fluffy when an instant-read thermometer inserted into the center reads between 205°F and 210°F (96°C–99°C).
