Method

Bring a large pan of salted water to the boil. Meanwhile, peel and quarter the potatoes (or halve any small ones – you want each piece to be the same size). Add them to the boiling water and cook for 15 minutes until very tender. Drain and allow to steam-dry for 5 minutes.
Meanwhile, heat the air fryer to 190°C. Add the oil, garlic and rosemary to a small saucepan over a medium heat and sizzle for a few minutes until the garlic is just starting to crisp. Put the potatoes in a large bowl, then pour the oil through a fine sieve over them, reserving the solids. Toss the potatoes in the hot oil, add the polenta (if using) and a big pinch of salt. Toss again, then immediately tip them into the hot air fryer, ideally in a single layer.
Cook for 30 minutes, turning or shaking the potatoes every 10 minutes. Add the reserved garlic and rosemary for the final 1-2 minutes of cooking. Season with a little more salt and serve.

Our top tips for the perfect air fryer roast potatoes:
1. Infusing the oil beforehand adds plenty of flavour without burning the garlic and rosemary during cooking.
2. Take the time to toss the potatoes in the infused oil until they’re completely coated – any parts of the potato not coated in oil will bake rather than roast.
3. Adding polenta is optional, but this is what gives the potatoes an extra-crunchy exterior.
4. Always try to add your potatoes to the air fryer in a single layer with a little space around each, so the hot air can reach each bit.
5. Shaking and turning the potatoes during cooking ensures even crispness throughout.
