What Temperature Should I Cook Pork Tenderloin

You can choose between two different cooking temperature: 325 degrees Fahrenheit (160 degrees Celsius) and 350 degrees Fahrenheit (180 degrees Celsius). Both temperatures are suitable for cooking pork tenderloin.

But, we recommend choosing 350 degrees Fahrenheit because it gives the juicy meat a nice crust without burning it.

If you prefer cooking pork tenderloin at lower temperatures, then use 300 degrees Fahrenheit (150 degrees Celsius).

Also, if you want a rich brown crust, cook your meat to an internal temperature of 160 degrees Fahrenheit for 20 minutes per pound.

You should cook your tenderloin to 350 degrees if you just want a uniformly cooked, soft, gentle meat. The result is not soggy, dry, brown, crispy, or pink. It comes out perfect.

However, if you prefer your mushrooms charred on the edges but still juicy in the middle, roast them at one of the other temperatures mentioned above. For crispy fans, 400 degrees F is the ticket.

For individuals who love the taste of meat melting in their mouths, 275 degrees is the key to achieving that, but it will take much longer

However, the baking time and cooking temperature are also determined by the meat weight. In other words, if you are grilling a tenderloin at 375 degrees Fahrenheit per pound, it should take around 25 minutes to cook.

For instance, if the weight of 3-pound pork tenderloin is to be baked in 1 hour and 15 minutes, it must first be trimmed of all fat.
