Question about Pork Tenderloin

egmdh2010 · March 2012

Hi all! I am going to be making a pork tenderloin for dinner this evening, and have a question about cooking time. The recipe I am using says to cook the pork at 425 for 25-35 minutes. However, that recipe is for a 2-pound pork tenderloin, and I am using a 3-pound pork tenderloin.

So, if it were you, how long would you cook the 3-pound pork? I don't want to under-cook, but at the same time, pork especially is one of those meats that just isn't as good when it's been over-cooked.

TIA for any advice you provide!!

My guess would be about 40-45 minutes, but a meat thermometer would be best. Cooking times vary so much based on the oven, the thickness of the roast, its temp when it went in, etc. A thermometer is much more accurate.

ETA: For pork, 160 is medium and 170 is well-done. Pull it out ~5 degrees before your desired temp and it'll gain those last few degrees from carry-over cooking while it rests.

use a meat theremometer. that's the best way to ensure it's cooked properly.

I agree with the previous posters. I usually use a probe thermometer so I can see the temp outside the oven. I cook it until the pork roast reads 160 degrees, then I let it sit for about 10 minutes out of the oven.

If it's 3 lbs, it's a pork loin, not a tenderloin. I would probably start with 45 minutes (I'd estimate 15-20 minutes/lb, but I would check at the lower end of that) and as others said, check the temp. I take it out when it's at 155-160 and let it rest under a foil tent, where it will go up another 10ish degree.
