🥔 Best Potatoes for Jacket Potatoes
The best potatoes for jacket potatoes are floury varieties, which bake up fluffy inside.
✔ Maris Piper
✔ King Edward
✔ Rooster
Avoid waxy potatoes, as they stay firm and lack that classic fluffy centre.
🌡️ Best Oven Temperature for Jacket Potatoes
For perfect results, use:
- 220°C (200°C fan)
- Gas Mark 7
This high temperature crisps the skin while allowing the inside to steam and soften.
⏱️ How Long to Cook a Jacket Potato
At 220°C (200°C fan):
✔ Medium potatoes: 60–70 minutes
✔ Large potatoes: 75–90 minutes
Turn once halfway through if cooking directly on a tray.
🧂 How to Prepare Jacket Potatoes
- Wash and scrub potatoes thoroughly
- Dry completely
- Prick skins a few times with a fork
- Rub lightly with oil
- Sprinkle with salt
Salt draws moisture to the surface, helping the skin crisp.
🔥 How to Get Extra Crispy Skin
✔ Bake directly on a wire rack
✔ Do not wrap in foil
✔ Use a hot oven from the start
✔ Finish with 5–10 minutes directly on the oven shelf
Foil traps steam and prevents crisping.
🔎 How to Tell When a Jacket Potato Is Done
A jacket potato is ready when:
✔ Skin feels crisp and dry
✔ A knife slides easily into the centre
✔ Inside feels soft and fluffy when squeezed
✔ Steam escapes when cut open
If still firm, return to the oven for 10 minutes.
⚠️ Common Jacket Potato Mistakes
❌ Wrapping in foil
❌ Cooking at too low a temperature
❌ Skipping oil and salt
❌ Not drying potatoes before baking
❌ Rushing the cooking time
Patience is key to perfect results.
❓ FAQs
Should jacket potatoes be wrapped in foil?
No — foil traps moisture and stops the skin crisping.
Can I cook jacket potatoes at 180°C?
Yes, but they’ll take longer and skins won’t be as crispy.
Do jacket potatoes need turning?
Only if cooked on a solid tray — wire racks don’t need turning.
Can I reheat jacket potatoes?
Yes — reheat in the oven, not the microwave, to keep skins crisp.
