How long to cook pork tenderloin in oven at 400 ° F?
Pork tenderloin only requires a short cooking time to avoid drying out the meat. More specifically, it should be baked for 20 to 25 minutes in a 400-degree F oven. The exact cooking time depends majorly on how long you want to sear them and the weight of the tenderloins. To achieve the best results, we recommend that you use a meat thermometer. If the thermometer reads 145 degrees then the pork is ready to be removed from the oven. You can also wait until the internal temp reaches 150 °F to make sure the pork is cooked through.
If you skip the searing step, bake the pork tenderloin until the surface is crispy and browned and the center is a little pink (about 25 – 35 minutes). However, it’s important that you sear the pork as this helps lock in the juices, making the meat juicy inside.
As mentioned above, the cooking time is also up to the pork tenderloin’s weight. You can bake it uncovered in the oven for about 20 to 25 minutes per pound. Another method is to use a thermometer as we suggested before.
