Semolina, a cheap pantry staple, outperforms expensive goose or duck fat in creating the crispiest roast potatoes, according to a recent test by lifestyle reporter Angela Patrone. Dusting parboiled potatoes with semolina before roasting absorbs excess moisture and forms a delicate, golden crust that remains crunchy and firm.
Why Semolina Works Best
Patrone explains that semolina strikes a perfect balance between grind fineness and natural flavour for roasted potatoes. Its high protein content creates a firm shell that withstands high temperatures without falling apart. Unlike flour, semolina does not become soggy and enhances the texture significantly.
“Much like flour crisps up the skin of fried chicken, a dusting of semolina removes excess moisture and hardens into a delicate crust after cooking in fat,” Patrone writes. She notes that vegetable oil, not goose or duck fat, produces incredible results when used as the cooking fat.
Step-by-Step Method for Crispier Roast Potatoes
To achieve the perfect roast potato—thick, golden, super crunchy on the outside and fluffy on the inside—follow these steps:
- Peel 1kg of potatoes and chop into equal quarters.
- Rinse potatoes to remove starch, then place in a pan of cold salted water. Starting with cold water ensures even cooking from the inside out.
- Bring to a boil and cook for 10 minutes. Drain and leave to cool covered with a clean towel for 10–15 minutes to absorb steam and dry the potatoes.
- Meanwhile, preheat the oven to 200°C Fan with a roasting tray inside. Once hot, add enough vegetable oil to cover the bottom of the tray and return to the oven for eight minutes.
- Once potatoes are dry, return them to the pan, put on the lid, and shake to increase surface area for semolina to stick.
- Add three tablespoons of semolina and sea salt to taste, then shake again to coat evenly.
- Transfer potatoes to the hot oiled tray, ensuring all sides are coated. Roast for 30 minutes, then turn them over.
- Reduce oven temperature to 180°C and roast for a further 25 minutes.
Patrone reports that the potatoes came out “incredibly golden, crispy and fluffy” with a perfect crunch.
Cost-Effective Alternative to Goose or Duck Fat
While many recipes call for goose or duck fat costing £3 to £5, semolina is a fraction of the price and readily available in most supermarkets. Patrone’s method proves that a simple ingredient can deliver superior results without the expense.
“You don’t need to be spending £3 to £5 on fancy goose or duck fat to get the crispiest roast potatoes when a cheaper ingredient gets the job done – and it works better,” she concludes.
