Air Fryer Recipe
Baked Sweet Potatoes
Baked sweet potatoes are a delicious and nutritious addition to any meal, and using an air fryer makes the process quick and easy.
Ingredients
- 2–4 medium-sized sweet potatoes
- Olive oil or cooking spray
- Salt and pepper to taste
- Your favourite herbs (like rosemary or thyme) or spices (such as paprika or cinnamon) – optional
Method
- Preheat your air fryer to 200°C (around 390°F) for about 5 minutes.
- Rinse and scrub the sweet potatoes thoroughly and pat them dry.
- Using a fork, poke several holes in each sweet potato.
- Lightly coat each sweet potato in olive oil or spray with cooking oil.
- Season the sweet potatoes with salt and pepper, and add herbs or spices if desired.
- Arrange the sweet potatoes in the air fryer basket in a single layer.
- Cook for 35-40 minutes, turning them halfway through.
- Test the doneness by inserting a knife or fork into the centre of the largest potato.
- Remove from the air fryer and let them cool for a few minutes before serving.
Why this works in an air fryer
Hot circulating air dehydrates the oiled skin while the dense centre slowly steams and gelatinises its starches. Pricking vents pressure so the potatoes do not split, and turning exposes both sides to the strongest airflow for more even softening and light skin crisping.
Equipment notes
Assumes a 4–6 litre basket holding 2–4 medium sweet potatoes with space between them; in a single-drawer model, place the largest potatoes at the outer hotter edges and turn halfway, while in a dual-zone air fryer use one zone for similar-sized potatoes or expect the fuller drawer to need 5–8 minutes longer.
Common pitfalls
- Knife meets a firm, chalky centre at 40 minutes? The potatoes are too large or cold from the fridge; drop to 180°C and cook in 8-minute bursts so the skin does not scorch before the middle softens.
- Skin looks wrinkled but damp rather than lightly crisp? The potatoes were not dried well after washing or are touching; pat dry next time and leave finger-width gaps so steam can escape.
- Blackened patches appear before the centre is tender? Too much oil or sugary spice is burning at 200°C; wipe off excess oil, reduce to 180°C, and add cinnamon or sweet rubs after cooking.
- Potatoes split wide and leak syrup into the basket? They were under-pricked or cooked too aggressively; use more fork holes along the top and turn gently, then line only the drip tray area if your model allows airflow to remain clear.
Variations & substitutions
- Swap olive oil for rapeseed oil for a more neutral flavour; cooking time stays the same, but the skin browns a little less assertively.
- Use smoked paprika, cumin and a pinch of chilli instead of herbs; add them lightly because dry spices darken quickly in the high airflow.
- Rub with rosemary or thyme and flaky salt for a savoury version; woody herbs tolerate the full cook better than soft herbs such as parsley, which should be added after cooking.
- For smaller sweet potatoes, start checking at 25 minutes; for very large ones, cook at 180°C after the first 25 minutes to give the centre time to soften without over-darkening the skin.
Storage & reheating
Keep cooled baked sweet potatoes in an airtight container in the fridge for up to 4 days, then reheat in the air fryer at 180°C for 8–12 minutes until hot through.
