Tips for roast potatoes & veg
- Cut pieces to a similar size so they finish together.
- A teaspoon or two of oil is plenty. Toss the pieces to coat them.
- Shake every 10 minutes so every side browns.
- Softer vegetables like peppers and courgettes cook faster than potatoes, so add them later.
Roast potatoes & veg: air fryer FAQs
How long do roast potatoes take in an air fryer?
Roast potatoes that take 200 °C for 45 minutes in the oven need 180 °C for about 33 min in an air fryer. Shake them every 10 minutes.
Can I cook frozen roast potatoes in an air fryer?
Yes, straight from frozen. A bag that says 220 °C for 40 minutes becomes 200 °C for about 29 min in an air fryer.
How long do roast vegetables take in an air fryer?
Mixed vegetables that roast for 35 minutes at 200 °C take 180 °C for about 25 min in an air fryer. Cut them to even sizes and toss them in a little oil.
Do I need to parboil potatoes for the air fryer?
No, but it helps. Parboiling for 5 to 8 minutes and roughing up the edges gives a fluffier inside and a crisper outside, as it does in the oven.
