Give the potatoes a thorough wash. Pat them dry and transfer them to a bowl.

Add the olive oil, salt & pepper, and dried rosemary. Toss the potatoes so they get an even coating of oil and seasoning.

Add the potatoes to your air fryer. This recipe works best if you don’t overfill the air fryer. I’d recommend splitting them into two batches and warming up the first before serving if you make more potatoes.

Fry them at 200° C (400° F) for about 20 minutes. Give them a good toss 10 minutes in to ensure they crisp up evenly.
