You can use a cast-iron skillet or any skillet that's safe to put into the oven. Then, preheat the oven while you prepare the tenderloin. Heating the skillet will help your tenderloin brown when you put it into the pan. Put on oven mitts and remove the hot skillet from the preheated oven. Set it on the stove and pour in 1 teaspoon (4.9 ml) of vegetable oil. Then, carefully swirl the pan a little so the oil spreads across the skillet. The oil will prevent the tenderloin from sticking to the hot skillet. Insert an instant-read meat thermometer into the thickest part of the tenderloin. Once it's reached at least 145 °F (63 °C), take the tenderloin out of the oven.
