Before You Start

Sweet potato fries are notoriously hard to crisp, but the air fryer and a light cornflour dusting solve it. You get crisp edges and a soft, sweet centre, with a smoky-savoury spice rub to balance the sweetness.

Instructions

1
Peel and cut the sweet potatoes into 1 cm fries. Pat them dry.
2
Toss with the cornflour first, then the oil, paprika, garlic powder and salt.
3
Preheat the air fryer to 190°C / 375°F. Spread the fries out with as much space as possible.
4
Air fry for 16 to 20 minutes, shaking every 5 minutes, until crisp at the edges.
5
Season with extra salt and serve at once, before they soften.

Ingredients

600 g sweet potatoes
1 tbsp (8 g) cornstarch
1½ tbsp olive oil
1 tsp smoked paprika
½ tsp garlic powder
¾ tsp fine salt

♨️ Air fryer notes

Cook at 190°C / 375°F and preheat for 2 to 3 minutes for the crispiest result.
Keep everything in a single layer with space around each piece. Overcrowding steams food instead of crisping it, so cook in batches if your basket is small.
Shake or turn halfway, and check a few minutes early, since air fryers cook faster than ovens and every model runs slightly differently.

💡 Cook's tips

The cornflour dusting is what crisps sweet potato, which is wetter and sweeter than regular spuds.
Serve immediately. Sweet potato fries soften faster than potato ones as they cool.

🔀 Make it your own

Add a pinch of cayenne or cinnamon to the rub.
Serve with a chipotle mayo or garlic aioli dip.

📦 Storing & reheating

Best fresh. Reheat at 190°C for 3 to 4 minutes to bring back some crunch.

❓ Frequently asked

Why are my sweet potato fries soggy?

They were probably crowded, or skipped the cornflour. Dust them lightly, spread them out, and shake the basket often.

Can I leave the skin on?

Yes, scrub them well and leave the skin for extra fibre and a rustic texture. Just cut them evenly.
