Pork Tenderloin

  • r

A very quick question from a novice cook, but an experienced eater...I've prepared a wonderful pork tenderloin marinade, but i'm at a loss for how long to cook in the oven...It's about 1.0 lbs, and given the weather, I must cook in the oven....Any idea how long and and what temp? I don't have a meat thermometer :( Thanks

  1. I do them at 375 for about 40 minutes. I would advise folding up the small end and trussing it so that you have a cylinder of meat roughly the same diameter all along. They should be a little on the rare side.

      Thanks you so much for the reply...Is that a little long for a one pound piece? I wouldn't want to dry it out, of course...

        I do mine at 425 for 25 minutes (preheat oven first). Maybe more time for larger cuts, but a pound is relatively small. It comes out nicely roasted on the outside, but slightly pink inside. Agree with trussing the end.

        It does sound long to me - esp for rare. Check it at 25-30 minutes - check the springiness and even cut into it at a thick section to look at the middle. And for cryin' out loud - order an instant read thermometer today...


      3. I think the last time I cooked one under the broiler: about 7-10 minutes on one side, then flip and 7-10 more minutes.

        Actually, since I got my little remote thermometer, I just set the temp I want, stick it in the roast, and then it beeps when it's ready. I don't even keep track of how long it takes anymore. It's great.

          I agree that broiling is the way to go, not roasting. It's too small a piece of meat to benefit from roasting. That timing sounds about right, but there are a lot of variables in broiling so you need to keep a close eye on things.

        2. Yes, truss for even cooking if you have twine. I don't usually have twine, so found that folding the meat onto itself and spearing w/ strong toothpicks works fine.

          I highly recommend searing the meat on the stove top first to achieve a great crust and seal in juices. On high heat, using an oven-proof skillet w/ a thin layer of canola/veggie oil, rotate meat to sear on all sides til you achieve a brown/caramel-colored crust. It may smoke up a bit, so have good ventilation or unplug the nearby smoke detector for a min. if you must. Make sure that you add a good amount of salt and pepper if you don't have much in your marinade.

          I think I have baked mine at 375 for about 20 min. in the past, but honestly, you should just go pick up a meat thermometer; most basic supermarkets carry them. I usually pull mine out about 5 degrees cooler than what those things suggest, but that's me. Important to let the meat rest for at least 10 min. before slicing. Good luck.

          1. Cooks Illustrated November/December issue has a method that includes pan searing on all sides followed by 10-16 minutes at 400 degrees in the oven.

            However, this is for tenderloin that is not brined or marinated but simply sprinkled with salt and pepper, preferably half an hour before cooking. Brining or marinating may change the time in the oven or moistness of the meat.

            They recommend removing from the oven when the internal temperature is 135 to 140. After a 10 minute rest, the temperature should be 145-150. They note that USDA recommends a final temperature of 160 but that they find it overcooked and dry. I tend to agree. The health issues that resulted in high temperatures for pork are no longer the problem they once were.

            1. First of all, get yourself an instant read thermometer. It makes cooking the meat so much easier. Then, cut off the silverskin that you will see on one side. Then fold back and tie the skinny end to make a log of about even size. I tie the loose flap at the top, too. Then, in a pan that can go into the oven, I sauté the marinated whole pork tenderloin on about three sides, a few minutes each, until nicely browned. Then into a preheated 400° oven for about 10 minutes. The trachina are killed at 137°, so I take it out when the temperature is about 140° to 145°. Let it sit, loosely covered with foil, for at least 5 minutes, better yet, 10 minutes. Then slice. It will be moist and delicious.
