The best way to cook jacket potatoes in an air fryer gives you what the oven promises but rarely delivers on a weeknight: properly crispy skin and a fluffy middle, in about 40 minutes instead of 90.

I was sceptical about air fryer jackets until I tried them properly. Now it’s my default method. Here’s the exact timing, temperature and technique for perfect results, plus what to do when things go sideways.

How to Get Best Way To Cook Jacket Potatoes In An Air Fryer Right Every Time

Right, let’s get into it. Here’s the approach I come back to every time, broken down so you can follow along without any guesswork.

Choose the right potato

Floury varieties like Maris Piper, King Edward or Russet give the fluffiest middles. Pick potatoes of similar size so they cook evenly, and give them a good scrub since you’ll be eating the skin. Medium-large potatoes, roughly the size of your fist, are ideal: tiny ones dry out and huge ones take forever.

It’s a small detail, but it’s exactly the kind of thing that separates a decent result from a great one.

Prep for maximum crispiness

Prick each potato several times with a fork so steam can escape (this also stops any dramatic exploding incidents). Rub the skins with a little oil and a generous pinch of sea salt. The oil crisps the skin; the salt seasons it and helps draw out moisture. Don’t wrap them in foil: foil steams the skin soft, which defeats the whole point.

This is the step most people skip, and it’s the one that makes the biggest difference.

Cook at 200°C for 35 to 45 minutes

Place the potatoes in the air fryer basket with space around each one for the air to circulate. Cook at 200°C for 35 to 45 minutes depending on size, turning them halfway through. They’re done when the skin is deep golden and crisp and a skewer slides through the centre with no resistance.

Get this bit right and everything that follows becomes noticeably easier.

Give them the fluffy-middle treatment

As soon as they come out, cut a cross in the top and squeeze the base gently so the middle bursts open and steams. This releases trapped steam and gives you that classic fluffy interior. Let them sit for two minutes before adding toppings so the steam escapes rather than making your fillings watery.

I learned this through trial and error so you don’t have to.

Load them properly

Butter first, always, so it melts into the fluffy potato. Then the classics: baked beans and cheese, tuna mayo, chilli con carne, coronation chicken, or cottage cheese with chives. For something a bit smarter, try smoked salmon with cream cheese and dill, or leftover curry. A jacket potato is a vehicle: the topping is the destination.

It sounds fussy, but it takes seconds and the payoff is real.

Troubleshoot the common issues

Skin not crisping? You probably crowded the basket or skipped the oil. Middle still hard? Your potatoes were too big or too different in size: give them 10 more minutes. Soggy bottom? They sat in the basket too long after cooking: get them out and cut them open straight away.

Once this becomes habit, you’ll do it without thinking and wonder why you ever did it differently.

Doing This in Britain

A quick word on the practical side of things here in the UK, because where you shop and what you buy does matter.

Baking potatoes are labelled as such in UK supermarkets and are usually Maris Piper or a similar floury variety. A 2kg bag costs around £1.50 and gives you four to six good jackets.

If you want the official word, the Food Standards Agency covers it well.

If you’re cooking for one, the air fryer wins on energy too: running a big oven for 90 minutes for a single potato is hard to justify with current energy prices.

Tips That Make a Real Difference

The main method above does most of the heavy lifting, but these little extras are what separate a decent result from a great one.

  • Don’t overcrowd the basket. Two large potatoes with air circulating beat four squashed together every time. I wish someone had told me this years ago.
  • A light spray of oil works as well as rubbing, and uses less. Any neutral oil is fine. No reason not to do this every time.
  • Parboiling for 8 minutes before air frying gives an even crispier skin, if you can be bothered. It takes seconds and saves headaches.
  • Leftover jacket potato halves reheat brilliantly in the air fryer and make great twice-baked potatoes with cheese. Obvious once you know it, easy to miss until then.

Mistakes That Trip Most People Up

Most problems people run into here come from the same handful of mistakes. Here’s what to watch for.

Wrapping in foil

Foil traps steam and gives you a soft, pale skin. For crispy skin, the potato needs direct hot air all round.

Skipping the pricking

Unpricked potatoes can burst dramatically as steam builds up inside. Ten seconds with a fork prevents it.

Cooking different sizes together

Small ones dry out while big ones stay raw in the middle. Match your potatoes or cook in batches.

Questions I Hear All the Time

Short answers to the questions I’m asked most often about this.

Do I need to parboil first?

No, it’s optional. Straight in the air fryer works perfectly. Parboiling just gives a marginally crispier skin if you want to go the extra mile.

Can I microwave first to speed it up?

Yes: 5 minutes in the microwave then 20 minutes in the air fryer gives good results. The skin won’t be quite as crisp as the full air fryer method, but it’s much faster.

The Bottom Line

Right, the short version of everything above:

Scrub, prick, oil, salt, 200°C for 35 to 45 minutes, cut open immediately. That’s the whole method, and it beats the oven on both time and crispiness. Keep a bag of baking potatoes in the cupboard and you’ve always got a proper dinner 40 minutes away.
