Wash and dry the potatoes then place them onto a chopping board. With a sharp knife, carefully slice down the middle lenghtwise and place the first half cut-side-down onto the board. Now start slicing each half into about 1cm thick slices.
Slice off the end bits if they are pointed, they will burn first so discard. Any other pieces that you are not using, bag and freeze for stews, soups and mash if you like.
Add the cut potato slices to a bowl or a large piece of parchment paper or a sheet pan to season them. Now add the salt, pepper, paprika and oil, use your hands to coat them all over, toss over the maizena/cornstarch and again with your hands, give them a quick toss.
Tip them into the air fryer basket, close and set the air fryer to 190C/374F for 20 minutes. Shake twice in that time, for the rest of the time, let them cook.
Serve with a touch of salt and a dipping sauce like ketchup, garlic aioli or sour cream.
Notes
Indicated nutritional information is estimated per person (4 people)
If you are using any mixed dried herbs or chili flakes, add them towards the end so they don't burn.
You can peel your sweet potatoes before air frying but it's an unecessary step, the skin is edible, healthy and it crisps up!
Shake the potato chips 2-3 times during the cooking process. I shook it twice and they were good so left them alone. No need to continue opening and closing.
