Question: how long to cook a 1 kg pork roast?
Answer: Turn the oven to 180°C and cook for 30-35 minutes per kg, depending on how well you like your roast cooked. Once cooked, let the roast rest for 10 minutes before slicing. One of the most important things when cooking a pork roast, is to dry off the rind as much as possible before you start cooking.
