Why you’ll love this recipe

For me, the best parts of a roast have always been the potatoes and Yorkshire puddings. When time is tight I developed quicker versions that still feel indulgent. These air fryer roast potatoes are crispy on the outside, soft and fluffy inside, and quick enough for weekly meals.

Air fryer roast potatoes – two methods

There are two reliable approaches here: the par-boil method and the tray method. Both produce crisp, tasty potatoes; par-boiling delivers the best interior seasoning and texture, while the tray method is faster and a great time-saver.

The par-boil method

Boil the potatoes briefly in salted water, drain and shake to fluff the edges, then steam-dry. Toss with oil and salt and air fry in a single layer until golden. Par-boiling seasons the flesh and makes it easier to roughen the edges, producing superior crispiness.

The tray method

The tray method skips par-boiling. Rinse and soak the potatoes to remove surface starch, dry them well, then place them in a sturdy foil tray with oil in the air fryer. After a few minutes of cooking, rough up the edges with a fork and baste as you turn them for a golden finish. The texture is slightly different to par-boiled roasties, but the result is still delicious and efficient.

Ingredients

Choose ingredients that give the best texture and handle the heat of the air fryer.

  • Potatoes: Use a floury variety such as Maris Piper, King Edward or Desiree for fluffy interiors.
  • Oil: Use sunflower, vegetable or rice bran oil rather than olive oil to avoid smoke.
  • Salt: Sea salt or table salt both work fine — season to taste.

If you’re not serving with a roast, pair these potatoes with roasted chicken, air fryer chicken breasts or air-fried peppers and onions for a complete meal.

Emma’s top tips

Use these practical tips to improve your results every time.

  • Potatoes shrink as they cook; factor that into portion sizes.
  • Smaller pieces cook faster; larger pieces take longer.
  • Avoid olive oil due to its lower smoke point.
  • For the tray method, soak for at least 10–15 minutes to remove starch, then dry thoroughly for crisp outsides and fluffy middles.
  • For the par-boil method, a light spray of oil during cooking helps baste and crisp the surface.
  • Don’t overcrowd the air fryer — give the air room to circulate so potatoes roast rather than steam.

Timings

Timings vary by air fryer model, potato variety and piece size. Use these as a guide.

  • Steam-dry: ~10–15 minutes.
  • Air fry: 18–22 minutes.

This recipe uses UK metric and US cup measurements where appropriate.

Ingredients

Basic ingredients for both methods. Quantities depend on potato size, air fryer capacity and portions. A medium potato per person is a good rule.

  • Floury potatoes, peeled and chopped (about 4–5cm pieces)
  • Sunflower or vegetable oil
  • Salt

Essential equipment

  • Large saucepan (par-boil method)
  • Tin foil and kitchen roll (tray method)
  • Air fryer
  • Two forks and a small plate (tray method)

Par-boil method instructions

Place prepared potatoes in a saucepan, cover with cold water, season well and bring to the boil. Simmer 5–10 minutes until a knife just pierces the potatoes. Drain, shake the pan to roughen edges and leave to steam dry for 10–15 minutes.

Preheat the air fryer to 190ºC (374ºF). Toss the dry, fluffed potatoes in oil and salt, then arrange in a single layer without overcrowding. Air fry for 18–22 minutes, turning once halfway and optionally spraying with a little oil during cooking, until crisp and golden. Serve immediately.

Tray method instructions

Rinse the prepared potatoes three times in cold water until the water runs clear and soak for at least 10–15 minutes. Meanwhile, make a sturdy foil tray (three layers folded) with the edges folded up so oil doesn’t run off and so it fits in your air fryer with space around the tray for airflow.

Drain and dry the potatoes thoroughly with kitchen roll. Preheat the air fryer to 190ºC (374ºF), place the tray inside, arrange the potatoes and drizzle with oil and salt. Air fry 5 minutes, then remove and roughen each potato’s surface with two forks on a plate. Return to the air fryer, baste with more oil and salt, and air fry for 8 minutes. Turn and baste again, air fry 5 minutes, then turn and baste once more and air fry 4–8 minutes until crisp and golden.

The roughing-up step helps create a craggy surface that crisps beautifully. Basting and salting each turn improves colour and flavour.

How to add flavour to air fryer roast potatoes

Add fresh or dried herbs such as rosemary, thyme or sage for a classic flavour. For a spicier twist, try smoked paprika, cayenne or chilli flakes. Toss with herbs after cooking or include them in the oil before roasting for a more subtle infusion.

FAQs

Why air fry roast potatoes?

Air frying is quicker than using an oven, often uses less oil, and frees up oven space. It’s also easier to clean and can produce excellent crispiness when potatoes are prepared correctly.

Why soak roast potatoes before air frying?

Soaking removes excess surface starch, helping moisture escape during cooking so the outsides get crisp while the inside stays fluffy. Rinse until the water runs clear, soak 10–15 minutes, then dry thoroughly.

Do you boil potatoes before air frying?

Boiling (par-boiling) is optional but recommended for the best texture and seasoning. The tray method skips boiling and still produces great results if you rinse, soak and dry the potatoes well.

How long do roast potatoes take in an air fryer?

Par-boil method: total prep and drying ~35–40 minutes plus 18–22 minutes air frying. Tray method: 10–15 minutes soaking and drying, then 22–26 minutes air frying. Adjust for potato size and your air fryer.
