A medium jacket potato usually takes around 40–60 minutes in an air fryer, depending on size and whether you pre-cook it in the microwave first.

Quick Scoop: Basic Timing

  • For raw medium potatoes (about 250 g each):
    • 180°C: about 40–60 minutes, turn halfway, until the skin is crisp and a knife slides in easily.
  • For large potatoes:
    • Add 10–20 minutes at the same temperature and start checking after 50 minutes.
  • For part-microwaved potatoes:
    • Microwave 8–10 minutes on high, then air fry at 200°C for about 10–20 minutes to crisp the skin.

Step‑by‑step: Classic Air Fryer Jacket

  1. Scrub and dry your baking potatoes, then prick them a few times with a fork or sharp knife.
  1. Rub with a little oil and sprinkle with salt for a crisp skin.
  1. Air fry in a single layer at 180°C for about 40 minutes, turning halfway.
  1. Test with a knife or skewer; if the centre still feels firm, continue in 5–10 minute bursts until fluffy inside.

Faster “Cheat” Method

Many home cooks use a microwave‑plus‑air‑fryer combo for weeknight speed.

  • Microwave 8–10 minutes on high, turning once.
  • Brush with oil and salt, then air fry at 200°C for about 10–20 minutes, turning halfway, until the skin is crisp.

This often gives a fluffy centre with crackly skin in roughly 20–30 minutes total cooking time after prep.

What Forums Say Right Now

Recent forum and Reddit threads show people debating timing because air fryers and potato sizes vary a lot.

  • Some users report needing 50–75 minutes at around 180°C for a fully fluffy middle, especially with big potatoes.
  • Others say 35 minutes is rarely enough and prefer checking from 50 minutes onwards.

A good rule: if an online recipe says 30–35 minutes and your potato is still hard, keep going; you’re not doing anything “wrong”, it just needs longer.

Mini Tips & Toppings

  • Aim for even‑sized potatoes so they cook at the same pace.
  • Don’t overcrowd the basket; air needs to circulate for maximum crispness.
  • Great toppings right now: cheese and beans, tuna mayo, leftover chilli, or roasted veg and hummus.
