Begin by scrubbing the russet potatoes thoroughly under running water to remove any dirt. Once clean, dry them completely with a kitchen towel.

Drizzle olive oil over each potato and rub it in to coat. Sprinkle kosher salt and black pepper evenly over the potatoes.

Place the potatoes in the air fryer basket without overcrowding. Cook at 400°F (200°C) for 35-40 minutes, checking at 25 minutes for doneness.

Pierce each potato with a fork to release steam. If tender when pressed, they're ready; if not, continue cooking.

Remove the potatoes, let cool slightly, slice open, and fluff the interiors before adding toppings.
