Prepare the Pork – Pierce the pork all over with a fork to help the flavors absorb, then rub it with 1 tablespoon of olive oil. Coat the tenderloin liberally with the Italian dressing seasoning and set aside.

Sear for Maximum Flavor – Preheat the oven to 380°F. In an oven-proof skillet, on the stove top over medium high heat, heat the remaining oil until it’s shimmery. Sear the pork on all sides until it develops a deep golden crust. This locks in the juices!

Deglaze the Pan – Remove the pork from the skillet and with the stove top still on, pour in the orange juice. Use a wooden spoon to scrape up all the flavorful brown bits, and cook 1-2 minutes until the orange juice is boiling. Remove from heat.

Bake Until Perfectly Juicy – Return the pork to the skillet, with the orange juice, and sprinkle the top with Italian seasoning blend, then top with butter pats by placing them directly on the pork in even intervals. Cover with foil and put the whole skillet in the oven to bake until the internal temperature reaches 145°F. This usually takes about 30 minutes, but check at 25 minutes with an instant-read thermometer for accuracy.

Rest & Serve – Once pork reaches the internal temperature (measured at the thickest part of the tenderloin), it is done.  Remove from the oven and let the pork rest for 5 minutes, tented with foil. This step is crucial for keeping it juicy! Slice against the grain and serve immediately.
