Ingredients

Scale
  • 2 to 3 pounds beef tenderloin
  • 2 tablespoons olive oil
  • 1 tablespoon salt
  • 1 tablespoon freshly ground black pepper
  • 2 tablespoons fresh rosemary (chopped) or 1 tablespoon dried
  • 2 tablespoons Dijon mustard
  • 2 tablespoons prepared horseradish
  • ½ cup sour cream
  • 1 tablespoon lemon juice
  • Fresh herbs for garnish (optional)

Instructions

  1. Preheat your oven to 425°F (220°C) to prepare for roasting the beef tenderloin.
  2. Remove the beef tenderloin from the refrigerator about 30 minutes before cooking. This helps ensure even cooking. Pat the beef dry with paper towels.
  3. Rub the beef tenderloin with olive oil, salt, and pepper. Then sprinkle the chopped rosemary evenly over the surface of the beef.
  4. In a hot skillet, sear the beef tenderloin on all sides for about 2-3 minutes per side until browned. This step helps lock in the flavor of your oven roast.
  5. Place the seared beef tenderloin on a roasting pan or baking sheet.
  6. Roast the beef in the preheated oven for about 25-30 minutes or until the internal temperature reaches 135°F (57°C) for medium-rare doneness. This is key for a perfect oven roast beef tenderloin.
  7. While the beef is roasting, prepare the horseradish-mustard sauce. Mix together the Dijon mustard, horseradish, sour cream, and lemon juice in a small bowl. Adjust seasoning with salt and pepper to taste.
  8. Once the beef reaches the desired temperature, remove it from the oven and let it rest for 10-15 minutes. This allows the juices to redistribute, resulting in a more tender beef tenderloin.
  9. After resting, slice the beef tenderloin into 1-inch thick slices. Arrange on a serving platter.
  10. Serve the beef slices with a generous spoonful of horseradish-mustard sauce over the top. Garnish with fresh herbs if desired for an elegant oven roasted beef tenderloin presentation.

Notes

  • Allow the beef tenderloin to come to room temperature before cooking for even results.
  • Experiment with different herbs like thyme or parsley for varied flavor in your oven roast beef tenderloin.
  • Use a meat thermometer to monitor the internal temperature for perfect doneness. The meat will continue to cook slightly after removal from the oven.
  • Do not skip the resting time; it’s crucial for juicy meat.
  • For added flavor, marinate the beef tenderloin in herbs and spices for 2-4 hours before cooking.
  • Leftover oven roast beef tenderloin can be stored in an airtight container in the refrigerator for 3-4 days.
  • Freeze slices of beef tenderloin for up to 3 months, wrapped tightly to prevent freezer burn.
  • Reheat thawed beef tenderloin in a low oven (around 300°F) to maintain tenderness.
