  • 2 pounds floury potaotes (Maris Piper or Yukon Golds)
  • ½ cup vegetable oil
  • 1 teaspoon rosemary
  • ½ teaspoon sea salt


  • Peel the potatoes, and dice into similar sized large chunks. Add them to a large pot of boiling water, and boil for about 5 minutes. The potatoes should be slightly softer on the surface, but not cooked yet.
  • Drain off the excess water from the pot. Cover the pot with a lid, and shake vigorously. The potatoes will be broken up on the surface, and look fluffy. This allows them to better absorb the oil, and become crispy.
  • Meanwhile, preheat the oven to 425 F / 220 C. Cover the bottom of a large roasting dish or baking sheet with a layer of vegetable oil or fat, and place this in the oven as it preheats to heat up the oil.
  • Carefully place the potatoes onto the hot oil on the roasting dish. I like to use tongs to avoid any hot oil from splattering. Turn the potatoes to coat them in oil on all sides, then place them in the oven.
  • Roast for about 40 minutes, or until the potatoes are crispy on the outside and soft on the inside. Turn them once halfway through cooking.
  • Remove the potatoes from the oven. Sprinkle some Maldon sea salt and rosemary on top, then serve.



  • Nutrition: Although the recipe calls for using ½ cup vegetable oil, please use enough oil to cover the bottom of your roasting dish. For the nutritional calculation, I have estimated how much oil is actually absorbed into the potatoes, as a portion of the oil will remain in the dish after cooking the potatoes.
  • Store leftovers in a refrigerator for up to 3 days.
