Thoroughly wash the russet potatoes under cool running water, then dry each potato completely with a clean towel.

Rub each dried potato with a light coating of canola or olive oil and generously sprinkle with salt and pepper.

Preheat the air fryer to 400°F (200°C) for about 5 minutes if required.

Place the seasoned potatoes in a single layer in the air fryer basket and cook at 400°F (200°C) for 40 minutes, checking for doneness.

Carefully remove the potatoes, slice each open down the center, fluff the insides with a fork, and add your favorite toppings.
