You can effortlessly create the Best-Ever Pork Tenderloin with Creamy Dijon Sauce by following these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C). This ensures even cooking for the pork tenderloin.
2. Season the Pork: In a small bowl, combine garlic powder, onion powder, salt, black pepper, and smoked paprika. Rub this mixture all over the pork tenderloin to season it well.
3. Heat the Oil: In a large oven-safe skillet, heat the olive oil over medium-high heat until hot but not smoking.
4. Sear the Pork: Place the seasoned pork tenderloin in the skillet and sear on all sides until golden brown, about 3-4 minutes per side. This adds depth of flavor to the meat.
5. Roast in the Oven: Transfer the skillet to the preheated oven and roast for 20-25 minutes or until the internal temperature reaches 145°F (63°C). Remove from oven and let rest for 5-10 minutes.
6. Prepare the Sauce: While the pork rests, add heavy cream and Dijon mustard to the skillet, scraping any flavorful bits from the bottom. Stir over medium heat until the sauce thickens, about 5 minutes.
7. Slice and Serve: Slice the pork tenderloin into medallions and drizzle the creamy Dijon sauce over the top. Garnish with chopped fresh parsley.

These steps will help you achieve a delightful pork tenderloin that’s tender, juicy, and packed with flavor.
