Question: how long should pork tenderloin be cooked?
Answer: Put the pork tenderloin in a baking dish that fits it easily without needing to bend it at all. Bake for 20-27 minutes, until the internal temperature on an instant read thermometer is at 145°F. Let the tenderloin rest on a cutting board for 5 minutes and then slice it in about 1/2-inch slices and serve.
