A good jacket potato needs two contrasting textures: a dry, crisp shell and a soft, steamy centre. The air fryer can produce both, but potato weight matters far more than most one-line recipes admit. Use the ranges below as starting points, then judge tenderness rather than trusting the timer alone.
For a medium 250 g baking potato, rub the clean, dry skin with a little oil and salt, then air fry at 190°C / 375°F for 40–50 minutes, turning halfway. It is ready when a thin knife slides easily through the centre. For a faster version, microwave until nearly tender, then air fry at 200°C / 400°F for 8–12 minutes to crisp the skin.
What you need
Choose a floury baking potato such as Maris Piper, King Edward or a potato sold specifically for baking. Floury varieties give a drier, fluffier middle than small waxy potatoes. Select potatoes of similar weight when cooking more than one so they finish together.
Scrub the skin, remove any damaged or green areas and dry it thoroughly. For each potato, use about half a teaspoon of neutral oil or olive oil plus a small pinch of salt. The oil is not essential for cooking, but it helps the salt adhere and makes the skin more appetisingly crisp.
- 1 baking potato per person, ideally 200–300 g
- 1/2 teaspoon oil per potato
- A small pinch of fine salt
- Butter and your preferred filling, to serve
How to cook a jacket potato in the air fryer
Prick the potato a few times with a fork or the tip of a small knife. Rub the dry skin all over with the oil and salt, then place it directly in the basket with space around it. Preheat only if your appliance manual recommends it.
Air fry at 190°C / 375°F, turning with tongs halfway through. Start checking at the lower end of the time range for its weight. Insert a thin knife or skewer through the thickest part: it should meet almost no resistance, and the potato should yield when gently squeezed with tongs.
Split the potato as soon as it is safe to handle so trapped steam does not soften the skin. Fluff the centre with a fork, season it and add butter before the filling.
Smart tipWeigh the potato before cooking. Two potatoes that look similar can differ enough to need another ten minutes, and adding several potatoes to the basket can extend the range further.
Jacket potato timings by weight
These timings are practical starting ranges for one potato. Air fryer power, basket shape, potato variety and the number being cooked all change the result. Two to four potatoes need a loose single layer; begin with the same range but expect the fuller basket to need five to ten minutes more.
Do not use colour alone as a doneness test. A crisp brown skin can surround a firm centre, particularly with a large potato or an air fryer whose heating element sits close to the basket.
The faster microwave-first method
Microwaving cooks the centre quickly, while a short air-fryer finish restores the crisp skin that a microwave cannot create. Prick the potato and microwave it on a microwave-safe plate until it is almost tender, turning once. An approximately 250 g potato commonly takes around eight to ten minutes in an 800 W microwave, but power and weight make a substantial difference.
Dry away surface moisture, rub with oil and salt, then air fry at 200°C / 400°F for 8–12 minutes. This method is ideal for a quick lunch. The slower all-air-fryer version normally gives a slightly drier, more evenly crisp shell.
How to get properly crisp skin
Drying matters: water left from washing must evaporate before the skin can crisp. Leave space around every potato, turn it once and avoid enclosing it in foil. Foil traps moisture against the skin and changes a baked texture into a steamed one.
If the middle is tender but the skin is still pale, raise the temperature to 200°C / 400°F for the final three to five minutes. Watch closely because small potatoes and protruding edges can darken quickly near the element.
Why the centre is hard or the skin is leathery
A hard centre simply needs more time. Reduce the temperature by 10°C if the outside is already dark, then continue in five-minute increments. Very large potatoes cook more evenly with the microwave-first method than with ever-higher air-fryer heat.
Leathery skin usually points to a damp potato, overcrowding or leaving the cooked potato intact while steam condenses beneath the skin. Dry it well before cooking, allow airflow and split it promptly after cooking.
Storing and reheating a cooked jacket potato
If you have a leftover potato, cool it and refrigerate it within two hours. The Food Standards Agency advises eating properly chilled leftovers within 48 hours or freezing them, and reheating leftovers only once.
Reheat an unfilled potato at 180°C / 350°F until it is steaming hot throughout; the exact time depends on its size and refrigerator temperature. Check the middle rather than relying on a fixed number. Keep fillings separate where possible, especially tuna mayonnaise or dairy-based toppings.
Air fryers vary in power and basket design. Use these timings as a starting point and follow your manufacturer’s instructions where they differ.
Frequently asked questions
How long does a jacket potato take in an air fryer?
A medium 250 g potato usually takes 40–50 minutes at 190°C / 375°F. Smaller potatoes may be ready in 30–40 minutes, while a 350 g potato can need close to an hour.
Do you need to microwave a jacket potato first?
No. Cooking it entirely in the air fryer normally gives excellent skin, but microwaving first can reduce the air-fryer stage to roughly 8–12 minutes.
Should you wrap a jacket potato in foil?
No if crisp skin is the goal. Foil traps steam and softens the skin. It can also interfere with airflow, so follow your appliance manual whenever foil is involved.
Do you have to pierce potatoes before air frying?
Pricking is a simple precaution that gives steam an escape route. A few shallow holes are enough; there is no need to stab deeply all over the potato.
Can you cook several jacket potatoes together?
Yes, provided they fit in one loose layer with air around them. Choose similar weights and allow extra time for a fuller basket.
