Which oil for crispy British roast potatoes?
Season : autumn, winter · Occasion : sunday roast, christmas, weekend
Cold-pressed rapeseed oil. Its smoke point sits near 230°C, well above olive oil's, so it can take the roaring oven heat that crisps a potato hard. Olive oil scorches and turns bitter at that temperature. Heat the oil in the tin first, then add par-boiled, roughed-up potatoes to the hot fat.
In detail
The best oil for crispy British roast potatoes is cold-pressed rapeseed oil, chosen for its heat tolerance. Its smoke point sits around 230 degrees Celsius, well above extra virgin olive oil's 190 or so, which means it can take the roaring oven temperature that crisps a potato hard without scorching or turning bitter. It is a British single-estate oil, cold-pressed on farms in the Yorkshire Wolds and the Cotswolds, with a grassy, nutty flavour that suits a Sunday roast better than a heavy import. The method matters as much as the oil: par-boil the potatoes until the edges go fluffy, shake them in the pan to rough up the surface, then add them to oil already heated in the tin so they sizzle on contact rather than steam. Goose fat gives more flavour, but rapeseed oil matches it on crunch. A 500ml bottle runs about £4.50 to £6.50.

Crispy roast potatoes need real oven heat, and cold-pressed rapeseed oil takes it: its smoke point is around 230 degrees Celsius, comfortably above extra virgin olive oil's 190 or so, so it crisps harder without turning bitter. It is a British single-estate oil from Yorkshire or the Cotswolds, with a grassy, nutty flavour that suits a Sunday roast. At about £4.50 to £6.50 a 500ml bottle, it beats imported olive oil at this one job.

The catch
Don't reach for olive oil on roast potatoes. It smokes around 190 degrees Celsius, below the heat you want for a hard crisp, so it scorches and turns bitter in a roaring oven. Cold-pressed rapeseed oil smokes near 230, so it takes the temperature that actually crisps a potato. Local, cheaper, and better at this one job than the import.
Chef's note
Par-boil the potatoes until the edges go fluffy, drain, then shake them hard in the dry pan to rough up the surface, that ragged edge is what crisps. Heat the rapeseed oil in the tin in the oven until it shimmers, tip the potatoes into the hot fat so they sizzle on contact, and turn them once halfway. Cold oil and cold spuds steam, not crisp.
Tasting note
grassy · toasted nut · hard crunch · golden · about £4.50 to £6.50 a 500ml bottle, and a tin's worth costs pennies. Worth it; it beats pricier olive oil at crisping.

Goose or beef dripping is the traditional rival and gives the most flavour, but rapeseed oil crisps just as hard, keeps it vegetarian, and is far cheaper per roast.

Frequently asked questions
- What is the best oil for crispy roast potatoes?
- Cold-pressed rapeseed oil, for the heat. Its smoke point near 230 degrees Celsius is well above olive oil's, so it can take the high oven temperature that crisps a potato hard without scorching or turning bitter. Goose fat or dripping give more flavour, but rapeseed oil matches them on crunch.
- Why not use olive oil for roast potatoes?
- Extra virgin olive oil smokes around 190 degrees Celsius, below the temperature you want for proper crisping, so it burns and turns bitter in a hot roasting oven. Rapeseed oil's higher smoke point lets you push the heat and get a harder crunch.
- Do you heat the oil before adding the potatoes?
- Yes. Heat the oil in the roasting tin in the oven first until it shimmers, then tip in the par-boiled, roughed-up potatoes so they sizzle on contact. Cold oil and cold potatoes steam instead of crisping.
