Bring a pot of salted water to a boil in a large saucepan while you peel and cut the potatoes. Blanch the potatoes in the boiling salted water for 4 minutes while you pre-heat the air fryer to 400ºF. Strain the potatoes and rinse them with cold water. Dry them well with a clean kitchen towel.

Toss the dried potato sticks gently with the oil and place them in the air fryer basket. Air-fry for 25 minutes, shaking the basket a few times while the fries cook to help them brown evenly. Season the fries with salt mid-way through cooking and serve them warm with tomato ketchup, Sriracha mayonnaise or a mix of lemon zest, Parmesan cheese and parsley. Yum!
