Scrub potatoes well under cold running water. Pat potatoes dry with a kitchen towel or some paper towels.

Place potatoes in the air fryer basket. It's easy to to get them in a single layer.

Cook at 400 degrees F 20 minutes. Turn them over so they cook evenly. Cook another 20 minutes.

Potatoes are done when they can be easily pierced with a knife or reach an internal temperature of 185 degrees F.

If your potatoes need more time, continue cooking in 2 minute increments.

When the potatoes are done, remove them from the air fryer basket and place them on a plate or cutting board to remove the skins.

Now add them to a large bowl along with the melted butter, sour cream and a splash of the milk and cream.

For best results, don’t add all the milk and cream at once.

Mash potatoes with a masher until smooth. Add more milk and cream as needed. Season with salt and pepper to taste.
