🥔 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

1. Wash and scrub potatoes thoroughly
2. Dry completely
3. Prick skins a few times with a fork
4. Rub lightly with oil
5. 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.

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.
