For the crispiest air fryer roast potatoes, parboil 1.5-inch chunks for 7–8 minutes, shake them rough, then air fry at 400°F (200°C) for 22–25 minutes. That’s the classic British-style Christmas method — craggy, crunchy edges and fluffy middles.
There’s roasted potatoes, and then there are proper crispy roast potatoes — the craggy, golden, crunchy-edged ones with fluffy insides that every Christmas table is judged by. The air fryer makes them better than the oven, in less time.
The secret: parboil, steam, shake
This is the old-school method, and it works even better in the air fryer:
- Parboil the chunks in salted water until the edges soften.
- Steam dry in the colander for a few minutes.
- Shake hard so the outsides get fluffy and scuffed.
All those little rough bits turn into crunch when they hit the hot air.

Which potatoes to buy
| Country | Best choices | Avoid |
|---|---|---|
| US | Russet, Yukon Gold | Red, new or fingerling (too waxy) |
| Australia | Dutch cream, Sebago, Coliban | Kipfler, Nicola (better for salads) |
| UK | Maris Piper, King Edward | Charlotte, Jersey Royals |
Fat matters (a little)
Olive oil gives great results and keeps them vegan. For special occasions, duck fat or beef dripping gives that rich, old-fashioned roast flavor. You only need 2 tablespoons for 2 pounds — far less than the oven method.
Christmas day timing
The potatoes take about 40 minutes start to finish, but you can do almost all the work early:
- Christmas Eve or morning: peel, parboil, rough up, toss in oil. Refrigerate uncovered.
- 30 minutes before eating: air fry from cold. They’re ready right when the ham or turkey comes out to rest.

Reheating
Leftover roast potatoes come back to life in the air fryer: 380°F (195°C) for 5–6 minutes. Honestly, they’re almost as good the next day.
Crispy Air Fryer Roast Potatoes
Shatter-crisp outside, fluffy inside: the parboil-and-rough-up method makes the best air fryer roast potatoes for Christmas, Sunday dinner or any night.
You'll need: Air fryer · Large pot · Colander
Ingredients
US cups and spoons with metric in brackets (1 US cup = 240 ml). A bigger batch may need two rounds in the basket: keep it to one layer.
Instructions
- Cut. Peel the potatoes and cut into chunks about 1.5 inches (4 cm). Similar sizes cook evenly.
- Parboil. Put them in a pot of cold water with 1 tbsp salt, bring to a boil and simmer 7–8 minutes, until the edges are soft but the centers still resist a knife.
- Steam dry and rough up. Drain well and leave in the colander for 3 minutes to steam dry. Then shake the colander hard so the edges get fluffy and scuffed — this is what makes them crunchy.
- Oil. Tip into a bowl and gently toss with the oil until coated.
- Air fry. Spread in a single layer in the basket. Cook at 400°F (200°C) for 12 minutes. Shake gently (or turn with tongs).
- Add flavor and finish. Add the garlic and rosemary and air fry 10–13 minutes more, until deep golden and crunchy all over.
- Season. Sprinkle with flaky salt and serve immediately.
Notes
- Don't skip the parboil. It's the difference between "roasted potato" and "crispy roast potato".
- Big batch: cook in two batches and keep the first warm in a 200°F (95°C) oven. Re-crisp everything together for 2 minutes before serving.
- Make ahead: parboil, rough up and oil up to 1 day ahead. Refrigerate uncovered, then air fry from cold, adding 3–4 minutes.
- Vegan and gluten-free when made with olive oil.
Air fryers vary by brand and size: start checking 2–3 minutes early. Recipe from shakethebasket.com/air-fryer-roast-potatoes/
FAQ
What are the best potatoes for air fryer roast potatoes?
Floury or all-rounder potatoes: russet or Yukon Gold in the US; Dutch cream, Sebago, Coliban or King Edward in Australia and the UK. Waxy potatoes stay smooth and don't get as crunchy.
Can I skip parboiling?
You can — cut smaller (1-inch / 2.5 cm), toss with oil and air fry at 400°F (200°C) for 20–25 minutes, shaking often. They'll be good, just not as craggy and crunchy.
Why are my roast potatoes not crispy?
Usually they were still wet, the basket was too full, or they weren't roughed up. Let them steam dry, shake hard, and cook in a single layer.
