Cooking Time For a 3-Lb Pork Tenderloin

By Wendy Hector

A pork tenderloin roast can be prepared in a multitude of ways. Brined or marinated, roasted or grilled, stuffed or glazed, you really can't go wrong with this cut of meat -- unless you cook it too long and it becomes dried out and flavorless. If you don't have a meat thermometer, keeping accurate track of cooking times is a necessity when preparing this meat.

Prepare the Roast

Step 1

Flavor your pork tenderloin with a dry rub, brine or marinade. Let sit to absorb flavors according to the recipe's directions.

Step 2

Once your pork is flavored and ready to go, remove it from its liquid -- if using a brine or marinade -- and set it out at room temperature for around 30 minutes.

Step 3

When the pork is ready, preset your oven temperature to 350.

Cook the Roast

Step 1

Heat oil in a large pan, preferably cast iron, over high heat.

Step 2

Sear the tenderloin on all sides until well-browned.

Step 3

In the same pan, or transferred to a roasting rack, insert the tenderloin into the oven.

Step 4

Cook 15 minutes per 1 lb., or about 45 minutes total for a 3-lb. roast.

Step 5

Remove the roast from the oven and let rest for 10 minutes before serving.
