Tender pork tenderloin is a flavorful dinner that you can have on the table in less than an hour. This easy-to-make dinner will soon be a family favorite.
Preheat the oven to 400 degrees and line a baking sheet with aluminum foil. Set aside.
In a medium bowl combine garlic powder, salt, pepper, dried parsley, and onion powder. Whisk to combine.
Pat pork tenderloin dry with paper towels. Sprinkle seasoning mixture on all sides, and on the ends of the pork too. Rub into pork with your fingers to evenly distribute seasonings.
In a large skillet over medium heat add olive oil. Once olive oil is hot and shimmering add the pork tenderloin and sear pork until browned on all sides. Once browned on all sides and ends, remove from the skillet and place on aluminum foil.
Place 3 squares of butter evenly spaced on top of the pork tenderloin and wrap aluminum foil tightly around the sides, top, and edges.
Place in the oven and let roast 20-30 minutes, or until the internal temperature reaches between 145 - 160 degrees in the middle of the tenderloin when tested with a meat thermometer.
