Question: how long does it take to cook a 9 pound pork shoulder?
Answer: Preheat the oven to 350 and cook roast for 2 hours at 350 and 3 and 1/2 hours at 325 degrees F. Roast the pork for 35 minutes per pound, uncovered, until the skin is crispy-brown. In order for the skin to become crunchy you will turn the oven up to 400 degrees and cook for an additional 20 to 30 minutes.
