First, rinse the potatoes clean. You can eat the skin but if you prefer the potatoes without skin you are welcome to peel them.
Preheat the air fryer to 375F.
While the air fryer is preheating toss the potatoes in oil then season the with salt and pepper. If you do not have coarse salt and pepper, fine grain is fine just use a little less.
Place the seasoned potatoes in the air fryer when it's ready. Cook for 15 minutes while flipping the potatoes after 5 minutes. This will make you do two flips of the potatoes to help them dry out properly and get crispy.
Once the air fryer sliced potatoes are finished serve with your favorite dip or main dish.
