Scrub the potatoes clean, then dry them thoroughly with kitchen paper.

Prick each potato several times with a fork to allow steam to escape.

Rub the potatoes all over with olive oil, then sprinkle with sea salt and a little black pepper.

Place the potatoes in the air fryer basket, leaving space around each one so the air can circulate.

Air fry at 200°C for 45 minutes, turning halfway through, until the skins are crisp and the potatoes feel soft when squeezed gently.

For larger potatoes, cook for a further 5-10 minutes if needed.

Carefully split each potato open, fluff the inside with a fork, then add butter and your chosen toppings.
