Peel and chop the potatoes into halves or quarters for even cooking.
In a large bowl, combine chopped potatoes with sunflower oil, plain flour, and onion granules. Mix until evenly coated.
Preheat your air fryer. Place the coated potatoes in the basket and shake for even spacing.
Cook the potatoes at 190℃/375F for 10 minutes, then shake the basket to ensure even cooking.
Continue cooking for another 5 minutes, shaking half-way through.
Cook for an additional 10 to 15 minutes until golden and crispy, monitoring to prevent burning.
For extra crispiness, increase the temperature to 200℃/400F and cook for an additional 5 minutes if needed.
Notes
include prepping potatoes while the air fryer heats up, ensuring even sizing for uniform cooking, and using a light hand with oil and flour for optimal texture.
