Perfect Air Fryer Roast Potatoes

These air fryer roast potatoes are cooked traditionally in hot oil at the base of the drawer, not on the crisper plate, for proper crispy results. Floury potatoes like Maris Piper or King Edward are parboiled, dusted with semolina for a crunchy coating, then air fried in preheated oil until golden. A knob of salted butter and black pepper added in the final minutes gives them deep flavour. Ready in just over 20 minutes from the air fryer, plus prep time.

Ingredients

Main
  • 1 kgfloury potatoes (Maris Piper or King Edward), peeled and cut into evenly sized roast potato shapes
  • 3 tbspcooking oil
  • 2 tbspsemolina
  • salt
Finishing
  • 1 knobsalted butter (add late)
  • black pepper, freshly ground (add late)

Method

  1. Peel the potatoes. Lay each potato on its side, cut about one third off the narrower end, then turn the larger piece and cut it in half the other way. This gives three evenly sized, proper roast potato shapes per potato.

    ~10 min
  2. Place the cut potatoes in a bowl of cold salted water and soak for 30 minutes to remove excess starch. If short on time, give them a thorough rinse under cold water instead.

    ~30 min
  3. Drain the potatoes, transfer to a pan and cover with boiling water from the kettle. Parboil Maris Piper or King Edward for no more than 5 minutes (waxier or larger potatoes may need up to 10 minutes). Do not over-boil or they will break up when roasted.

    ~5 min
  4. Meanwhile, remove the crisper plate from the air fryer drawer (it can dry the potatoes out). Add 2-3 tablespoons of cooking oil to the bottom of the drawer and preheat at 200°C (392°F) for 5 minutes.

    ~5 min
  5. Drain the parboiled potatoes and return them to the dry pan. Sprinkle over 2 tablespoons of semolina, put the lid on and give them a good shake to roughen the edges and fully coat them.

    ~1 min
  6. Carefully tip the potatoes into the hot oil; they should sizzle on contact. Immediately turn them over so every side is coated in oil. Spray any dry-looking patches with a little extra oil. Do not overcrowd the drawer.

    ~2 min
  7. Air fry at 200°C (392°F) for 20 minutes. Every few minutes, gently shake the drawer or turn the potatoes with tongs for even cooking, spraying any dry spots with oil and adding a little salt as you go.

    ~20 min
  8. When 8-10 minutes remain, add a generous knob of salted butter and a grind of black pepper. Shake or turn occasionally so the potatoes are completely coated in the flavoured butter. Add garlic, rosemary, thyme or paprika here if you like.

    ~8 min
  9. Check the potatoes at 20 minutes; they should be golden, crispy and sizzling. If needed, return them for a further 3 minutes.

    ~3 min
  10. Tip the potatoes into a large bowl with plenty of space around them so they do not steam and lose their crisp. Finish with a final sprinkle of salt and serve straight away.

Frequently asked

Why remove the crisper plate?
Roasting straight on the base of the drawer in hot oil gives you proper crispy, oven-style roasties. Cooking on the crisper plate tends to dry them out and you lose that deep golden crust.
Do I really need the semolina?
Yes, this is the secret to the crunch. Two tablespoons of semolina shaken over the hot, drained potatoes clings to the fluffy edges and crisps up beautifully in the oil. Once you try it, you will not go back.
Which potatoes work best?
Floury varieties like Maris Piper or King Edward. Waxy potatoes can be roasted but the results are less reliable and you will need to parboil them for longer (up to 10 minutes).
Do I need to preheat the air fryer?
Yes. Preheating with the oil at 200°C for 5 minutes means the potatoes hit hot oil and sizzle straight away, which is essential for the crispy outside.
Why add butter only at the end?
Butter burns at high temperatures, so adding it in the last 8-10 minutes gives you all the flavour without it scorching. It also helps the seasonings stick.
