British Roast Potatoes are a beloved side dish made by parboiling potatoes, roughening their surfaces, and roasting them in hot fat until golden and crispy on the outside while fluffy inside. They are a staple of the traditional British Sunday roast and Christmas dinner, typically seasoned with salt, pepper, and sometimes herbs like rosemary or thyme.
This dish is high in carbohydrates and fat, with the fat content depending on the type and amount of cooking fat used (such as duck fat, beef dripping, or oil). A typical serving provides energy, some potassium and vitamin C from the potatoes, and contains roughly 200-300 calories.

The secret to achieving the perfect crispy exterior lies in the parboiling step, which creates a starchy, rough surface that crisps up dramatically in the oven. Nutritionally, while the roasting process increases calorie density, the potatoes themselves are a good source of resistant starch when cooled, which can benefit gut health.
