Preheat the oven to 200°C / 400°F
Place the jacket potato directly on the oven rack or on a baking tray
Heat for 15–20 minutes, or until hot through
For a crispier skin, rub the potato with a little oil before reheating
Microwave on a microwave-safe plate for 2–4 minutes if you need a faster option
Turn the potato halfway through microwaving for even heating
Check the center is steaming hot before serving
Reheat only once
Store leftover jacket potatoes in the refrigerator within 2 hours of cooking
