Perfectly seasoned, then roasted with butter and fresh herbs in a cast-iron skillet, this is the BEST Pork Tenderloin ever! Juicy, tender pork tenderloin is super simple to make for a weeknight meal, Sunday supper and is special enough for entertaining.
In a small bowl, mix together Dan-O's seasoning, salt, paprika, and pepper. Coat the pork tenderloin.
In a separate bowl, mix together the lemon zest and chopped parsley, then set aside.
Heat a cast-iron skillet over medium-high heat. Drizzle in olive oil and sear the pork tenderloin on all sides. Turn off heat, dot the tenderloin with butter, and sprinkle on lemon zest and parsley. Cover with aluminum foil and place in the oven.
Roast the pork for 20-25 minutes until the internal temperature reaches about 145. Remove the skillet from the oven and let the meat rest for 10 minutes. Slice the tenderloin and drizzle with pan juices. Sprinkle with additional parsley and serve.
