The Best Juicy & Perfect Pork Tenderloin Recipe

A beautiful plate of homemade, sliced Pork Tenderloin with a creamy mustard sauce, served with roasted asparagus for an elegant meal.

An elegant recipe for a perfectly cooked pork tenderloin with a rich and flavorful herby mustard cream sauce. The pork tenderloin is coated in a crust of crushed peppercorns and fresh herbs, then pan-seared to create a golden-brown exterior before being finished in the oven. A creamy pan sauce is then made in the same skillet using the pan drippings, fresh herbs, garlic, heavy cream, and whole-grain mustard. The rested pork is sliced and served with the sauce.

Ingredients

  • For the Pork Tenderloin:
  • 1 tablespoon tri-color peppercorns
  • 1 tablespoon kosher salt
  • 1 teaspoon minced fresh thyme
  • 1 teaspoon minced fresh rosemary
  • 1/2 teaspoon crushed red pepper (optional)
  • 1 1/2 to 2 pounds pork tenderloin (2 tenderloins)
  • 2 tablespoons olive oil
  • For the Herby Mustard Cream Sauce:
  • 3 tablespoons salted butter
  • 2 cloves garlic, minced
  • 1 teaspoon minced fresh thyme
  • 1 teaspoon minced fresh rosemary
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups heavy cream
  • 2 tablespoons whole-grain mustard
  • 2 tablespoons chopped fresh parsley, plus more for garnish

Instructions

  1. Preheat the oven to 425°F.
  2. Crush the peppercorns coarsely. In a bowl, mix them with the salt, 1 teaspoon of thyme, 1 teaspoon of rosemary, and the optional crushed red pepper.
  3. Rub the seasoning mix all over the pork tenderloin.
  4. Heat the olive oil in a large, heavy-bottomed ovenproof skillet over medium-high heat. Add the pork and cook for about 5 minutes, turning as needed to brown all sides.
  5. Transfer the entire skillet to the preheated oven and bake for 15 to 20 minutes, until a meat thermometer inserted into the thickest part reads 145°F.
  6. Transfer the pork to a cutting board and tent it with foil to rest.
  7. Make the Sauce: Return the skillet to the stovetop over medium heat. Melt the butter, then add the garlic, 1 teaspoon of thyme, and 1 teaspoon of rosemary. Cook for one to two minutes until fragrant.
  8. Sprinkle in the flour and cook, stirring, for one additional minute to form a roux.
  9. Whisk in the heavy cream and bring the sauce to a simmer. Let it simmer for about 2 minutes until it thickens slightly.
  10. Stir in the whole-grain mustard and the chopped parsley. Taste and adjust seasoning as needed.
  11. Slice the rested pork and arrange it on a platter. Spoon some of the sauce over the top and serve the remaining sauce on the side.

Notes

  • Using an ovenproof skillet is essential for this recipe, allowing you to go from searing on the stovetop to roasting in the oven with the same pan.
  • A meat thermometer is the most reliable way to ensure the pork is cooked to the perfect temperature (145°F) without being overcooked.
  • Letting the pork rest after roasting is a crucial step that allows the juices to redistribute, ensuring a tender and moist result.
