Wash and dry the sweet potatoes thoroughly and set aside while making the seasoning.
Mix the salt, black pepper, paprika, ground cinnamon, onion powder and garlic powder together in a small bowl. Set aside while preparing the sweet potato.
Cut the ends off the sweet potatoes and then halve them lengthwise.
Slice the sweet potato into long wedges and toss them into a large bowl.
Add the olive oil and the seasoning mix to the bowl with the wedges and toss to coat.
Transfer the seasoned wedges to the basket of the preheated air fryer. Lay them in the basket, making sure they are not touching. You may need to cook them in multiple batches.
Bake for 10 minutes, then flip them over and bake for a further 4-5 minutes, until your desired crispiness is reached.
Remove from the air fryer and let cool for a few minutes before enjoying.
