Quick answer: Rub a medium potato (about 200–250g) with oil and salt, then air fry at 200°C (400°F) for 40–45 minutes, turning once halfway. It’s done when a skewer slides into the centre with no resistance and the inside reaches about 98°C (208°F). No foil, no preheating needed.
A baked potato — a jacket potato, if you’re in the UK — is one of the things an air fryer does better than a full-size oven. The fan blows hot air right across the skin, so you get that crackly, salty shell in less time and for a fraction of the electricity. Below are exact times by size, the prep that actually makes a difference, and the mistakes that leave you with soft skin or a hard middle.
Air Fryer Baked Potato Times by Size
All times are at 200°C (400°F), turning the potatoes once halfway through. Weigh one potato if you can — weight is a far better guide than “medium” or “large”.
| Potato size | Approx. weight | Time at 200°C (400°F) |
|---|---|---|
| Small | 120–170g (4–6oz) | 30–35 minutes |
| Medium | 200–250g (7–9oz) | 40–45 minutes |
| Large | 280–350g (10–12oz) | 45–55 minutes |
| Extra large / baking potato | 400g+ (14oz+) | 55–65 minutes |
| Sweet potato (medium) | 200–250g | 35–45 minutes |
Cooking several at once? Keep them in a single layer with a little space between each one. Four medium potatoes in a 5–6L basket usually adds only 3–5 minutes. If they’re touching, turn them twice rather than once so the contact points crisp too. For other foods and portion sizes, our Cooking Time Calculator does the maths for you.
What You Need
- Floury potatoes — Russet (US/Canada), Maris Piper or King Edward (UK). Waxy potatoes like Charlotte stay dense and won’t go fluffy.
- 1 tsp oil per potato — olive, sunflower or rapeseed/canola all work.
- Coarse salt — flaky sea salt or kosher salt sticks to the skin and gives the best crunch.
- Toppings of your choice (ideas below).
How to Make a Baked Potato in the Air Fryer (Step by Step)
- Scrub and dry thoroughly. Wash off any soil, then dry the skin completely with a clean towel. Wet skin steams instead of crisping — this is the single most skipped step.
- Prick 4–5 times with a fork. This lets steam escape so the flesh cooks through evenly.
- Oil and salt. Rub about a teaspoon of oil over each potato, then roll it in coarse salt so the whole surface is coated.
- Air fry at 200°C (400°F). Place in the basket in a single layer — no need to preheat — and cook for the time in the table above.
- Turn halfway. Flip each potato with tongs so the underside gets the same direct airflow as the top.
- Check doneness. A skewer or thin knife should slide to the centre with zero resistance. If you have a probe thermometer, look for 96–99°C (205–210°F) — the point where the starch turns properly fluffy.
- Cut open immediately. Slice a cross in the top and squeeze the sides so the steam escapes. Leaving it closed lets steam soften the skin you just crisped.
The Secret to Really Crispy Skin
If your air fryer potatoes come out with leathery rather than crackly skin, it’s almost always one of three things:
- Surface moisture. Dry the potato properly after washing. Even a thin film of water turns the first 10 minutes into steaming.
- Too little salt. Coarse salt draws moisture out of the skin as it cooks. Fine table salt dissolves and doesn’t do the same job.
- Foil. Wrapping a potato in foil traps steam against the skin — you get a soft, oven-style jacket. In an air fryer, cook them bare.
For an extra-crisp finish, brush the skin with a little more oil for the last 5 minutes and turn the heat up to 210°C (410°F) if your model allows it. Still not getting the crunch you want? Our guide to why air fryer food isn’t crispy covers the common causes, and the Crispiness Adjuster suggests time and temperature tweaks.
The 20-Minute Shortcut: Microwave, Then Air Fry
If 45 minutes is too long for a weeknight, split the job:
- Prick the potato and microwave on high for 5–6 minutes for a medium potato (7–8 minutes for large), turning once.
- Pat dry, rub with oil and salt.
- Air fry at 200°C (400°F) for 12–15 minutes until the skin is crisp.
You’ll get about 90% of the texture in half the time. The flesh is slightly less fluffy than a full air-fried potato, but on a busy evening most people won’t notice. Curious which appliance suits which job? See air fryer vs microwave.
Air Fryer vs Oven Baked Potato
A conventional oven usually needs 60–75 minutes at 200°C, plus 10–15 minutes of preheating, for a single medium potato. The air fryer does the same job in 40–45 minutes from cold, with crispier skin, while drawing much less power. If you’re cooking one or two potatoes, the air fryer wins on time, texture and running cost. For six or more, the oven’s capacity starts to make sense.

Best Baked Potato Toppings
- Classic: butter, sour cream and chives.
- British jacket potato: baked beans and grated cheddar, or tuna mayo with sweetcorn.
- Loaded: cheddar, crispy bacon, spring onion and sour cream — return to the air fryer for 2–3 minutes to melt the cheese.
- Chilli: leftover chilli con carne with a spoon of yoghurt.
- Lighter: cottage cheese, black pepper and cherry tomatoes.
- Broccoli and cheese: pair it with our crispy air fryer broccoli.

Common Mistakes to Avoid
- Using mixed sizes. A large and a small potato won’t finish together. Choose similar sizes, or take the small one out early.
- Overcrowding the basket. Potatoes stacked on top of each other cook unevenly and the skin stays pale where they touch.
- Judging by time alone. Potato density varies. Always test with a skewer before you pull them.
- Letting them sit. A cooked potato left whole in the basket goes soft as it steams. Open it straight away.
Storing and Reheating Leftover Baked Potatoes
Cool completely, then refrigerate in an airtight container for up to 3–4 days. Don’t leave cooked potatoes at room temperature for more than 2 hours. To reheat, air fry at 180°C (350°F) for 8–10 minutes for a whole potato, or 5–6 minutes for halves — the skin crisps back up far better than in a microwave. Our Leftover Reheat Guide covers times for other foods too.
Frequently Asked Questions
How long does a baked potato take in the air fryer?
A medium potato (200–250g) takes 40–45 minutes at 200°C (400°F). Small potatoes take 30–35 minutes and large baking potatoes 50–65 minutes, depending on weight.
Do I need to preheat the air fryer for baked potatoes?
No. Because the cook is long, preheating only saves a minute or two. Put the potatoes in cold and start the timer.
Should I wrap potatoes in foil in the air fryer?
No. Foil traps steam and softens the skin. Cook them unwrapped with oil and coarse salt for the crispiest result.
Do you have to poke holes in potatoes before air frying?
It’s strongly recommended. Pricking lets steam escape so the inside cooks evenly, and it removes the small risk of a potato splitting under pressure.
What temperature should a baked potato be inside?
Around 96–99°C (205–210°F). Below that, the centre can be waxy; in that range the starch is fully cooked and fluffy.
Can I cook a sweet potato the same way?
Yes. A medium sweet potato takes 35–45 minutes at 200°C (400°F). Put a small piece of baking paper under it, as the sugars can leak out and caramelise onto the basket.
Why is my air fryer baked potato hard in the middle?
It needs more time — usually because it’s heavier than expected or the basket was overcrowded. Add 5-minute increments and test with a skewer each time.
