A porketta roast bakes in an oven at 350 degrees Fahrenheit until the internal roast temperature reaches between 160 and 170 degrees Fahrenheit. The baking time is between 30 to 45 minutes per pound of thawed roast.
After the roast temperature reaches 160 degrees Fahrenheit, remove the roast from the oven, and let it sit at room temperature for approximately ten minutes. The meat juices from the roast are clear when the porketta has finished cooking. A porketta roast comes from a pork shoulder cut that is deboned, spice-rubbed and tied back together with netting. You may keep the netting in place while baking.
