You will never need another recipe after making these! A polenta crust and cooking in duck fat ensures the roast potatoes are perfectly crisp on the outside and fluffy on the inside
4lbs potatoes, preferably Yukon Gold
8 tbsp duck fat
5 tbsp polenta grains
Preheat the oven to 400 F
Parboil the potatoes in salted water for about 10 minutes or until slightly tender when tested with a knife.
Drain well, return to the pan and cover with the lid.
Shake the pan fairly vigorously to roughen the outsides of the potatoes.
Spoon the duck fat into a large roasting tin and place in the oven for 5 minutes or until the fat is hot and melted.
Sprinkle the polenta over the potatoes and toss to coat (this will make them extra crispy). Carefully tip the polenta-coated potatoes into the roasting tin and turn gently to coat in the hot duck fat.
Roast for about 45 minutes, or until crisp and golden brown.
