Jacket potatoes are a cherished midweek favourite across the UK, loved for their versatility and ease. Whether topped with classic baked beans and cheese or more modern options like barbecue pulled pork or truffle mac n cheese, a well-cooked jacket potato is comfort food at its finest. However, achieving that perfect balance of a crispy, golden skin with a soft, fluffy interior can be surprisingly tricky.
Many home cooks shortcut the process by microwaving before finishing in an air fryer, but chefs caution this method can lead to disappointing results. The key to a great jacket potato lies in patient oven-baking and one crucial step: piercing the skin before cooking. This simple action allows steam to escape, preventing sogginess and helping the skin crisp beautifully.
Mark Hartstone, chef proprietor of La Fosse in Dorset, advises washing the potato, piercing it with a metal skewer, then seasoning with coarse sea salt before roasting at 180°C until tender and golden. Similarly, Henry Firth and Ian Theasby of BOSH! stress thoroughly pricking the skin with a fork, massaging in olive oil, coating with fine sea salt, and baking directly on the oven rack at 200°C fan for 60-75 minutes.

George Ryle, formerly a London restaurant chef, highlights the importance of time and method. Skipping microwaves, he scores washed, dried potatoes with a sharp knife, oils, seasons with flaky salt and cracked black pepper, and bakes them on a rack at 180°C fan for up to 1.5 hours. This technique creates a subtle Hasselback effect, enhancing crispness and flavour.
Christine Pittman, founder of COOKtheStory, recommends scoring a cross on the potato’s side without adding oil or salt before placing it directly on the oven rack at 200°C. She emphasizes the importance of using floury varieties like Maris Piper or King Edward for a fluffy inside, warning that waxy potatoes retain too much moisture.
Jamie Newman from Croeso Pubs endorses pricking the skin with a fork, rubbing olive oil and salt over it, and baking for around an hour until tender. He suggests microwaving as a time-saver if needed but insists true crispness comes from thorough oven baking. Classic fillings like beans and cheese remain favourites, but new combinations elevate the humble spud.
Chef Simon Ball recommends a criss-cross cut on the potato’s surface, followed by olive oil, salt, and pepper before baking for up to 1 hour 45 minutes at 180°C. He praises Albert Bartlett Rooster potatoes for their excellent texture.
James Cotton of Brakes Foodservice echoes the advice to wash, dry, and prick the potato skin multiple times to release steam. He advises avoiding foil and baking on an oven rack at 200°C for about 1 hour 15 minutes. For an extra fluffy centre, James suggests gently squeezing the potato with oven mitts about 15 minutes before it’s done, then returning it to the oven to finish.
In summary, while techniques vary, top chefs agree on the essentials: use a floury potato, pierce or score the skin to vent steam, bake on an oven rack at a steady high temperature, and resist shortcuts like microwaving. Follow these tips, and you’ll enjoy jacket potatoes with irresistibly crispy skins and beautifully fluffy interiors every time.
