What temp and how long do you cook pork tenderloin in a gas oven

Yes, use a thermometer and pull out at 140. Consider wrapping it in prosciutto or bacon. Is it stuffed?

I also cook at 425 degrees until it reaches a internal temp of 150 then let it sit tented with foil final temp for me is 150-160 after resting I also pan sear first then finish in the oven. It takes about 20 minutes as said above.

I like to cook mine on 425 for about 20 minutes, or until the internal temperature reaches about 140 degrees.
