A full printable version of this recipe with ingredient measurements is available at the bottom of this post.
STEP ONE: Preheat the oven to 425 degrees F and place a large cast iron skillet over medium-high heat.
STEP TWO: In a small bowl, combine salt, rosemary, paprika, and garlic powder. Mix them thoroughly, then rub the mixture onto all sides of the pork tenderloins, ensuring they are evenly coated.
STEP THREE: Once the skillet is hot, add olive oil and swirl it around to coat the entire pan. Carefully place the seasoned pork tenderloin on the stove and sear them on all sides until they develop a beautiful brown crust. Add some butter and garlic to the skillet, then spoon the mixture over the meat as you pan fry pork tenderloin.
STEP FOUR: Transfer the skillet to the preheated oven. Bake cast iron pork tenderloin for about 20 minutes, or until the internal temperature reaches 145 degrees F.
STEP FIVE: Once the pan seared pork tenderloin is cooked, remove them from the oven and let them rest for 5 minutes. This allows the juices to redistribute and ensures a moist and flavorful result.
STEP SIX: Sprinkle cast iron pork tenderloin with freshly chopped parsley before serving.

What is the Difference Between Pork Tenderloin and Pork Loin?
Pork loin is a larger cut often covered with a thick fat cap that does really well with slow cooking methods. Bone-in cuts are often cooked as a rack, while boneless cuts are used as roasts or sliced into chops.
Instead, pork tenderloin is a smaller, leaner cut of meat that comes from the muscle beneath the backbone. It does best with quick cooking methods, like our pork tenderloin cast iron recipe! Tenderloin also has a more delicate flavor, making it a great candidate for rubs and marinades.
Should I Sear Pork Tenderloin Before Baking It?
Yes, and that’s exactly what we do in this pork tenderloin cast iron recipe! Not only does searing meat create a delicious crust on the outside, but it helps to lock in all of the juices for perfectly tender and moist results.
Cast iron is the best option for pan seared pork tenderloin — it heats hotter and more evenly than other types of pan and can straight from the stovetop to the oven!
Can Pork Tenderloin be 145 and Still Pink?
The safe minimum internal temperature for seared pork tenderloin is 145 degrees F, regardless of the color. Use a digital meat thermometer inserted into the very center for the most accurate results.
If the color bothers you, pan fry pork tenderloin a little bit longer before it goes in the oven. It can go up to 155 degrees F before it starts to dry out.
