Oven Roasted Beef Tenderloin With Sour Cream Sauce Recipes

Steps:

• Preheat the oven to 275 degrees F. Line a sheet pan with aluminum foil.
• Pat the entire tenderloin dry with paper towels and brush it all over (top and bottom) with the butter. Sprinkle the tenderloin all over with 4 teaspoons salt and 2 teaspoons pepper. It will seem like a lot but trust me, it's important.
• Place the tenderloin on the prepared sheet pan and roast it for 1 to 1 1/4 hours, until an instant-read thermometer inserted into the end of the filet registers 130 degrees F for medium rare. Remove from the oven, cover tightly with aluminum foil, and allow to rest at room temperature for 15 minutes. Discard the foil and allow to sit at room temperature.
• Meanwhile, for the sauce, whisk together the mayonnaise, sour cream, mustards, horseradish, and 1/4 teaspoon salt in a small bowl. Refrigerate until ready to serve.
• Remove the strings and slice the filet between 1/4 and 1/2 inch thick, sprinkle with salt, and place on a platter with a garnish of parsley. Serve warm, at room temperature, or cold with the sauce on the side.

Steps:

• Preheat oven to 325°F.
• In a small bowl mix together parsley, rosemary, thyme, garlic, oil, pepper, and 2 tbsp of Dijon mustard.
• Rub mixture all over tenderloin and place in a shallow roasting pan (9x13 or larger). Insert meat thermometer into center of meat, if desired.
• Roast uncovered for 30-45 minutes or until thermometer reads 140°F for medium rare-medium doneness. Remember meat will continue to cook while standing.
• Remove meat, cover with foil, and let stand 15 minutes to let juices redistribute.
• While meat is standing, in another small bowl, stir together the sour cream and 2 tsp Dijon mustard.
• Slice tenderloin. Serve warm with sour cream mustard sauce drizzled atop.
• NOTE: can prepare tenderloin ahead, slice thinly and serve atop a toasted baguette with sour cream mustard sauce and horseradish sauce as an appetizer for dinner party. Also great thinly sliced over a hearty salad.

Steps:

• Mix parsley, butter, and 3 tablespoons Dijon together in a small bowl. Combine green and pink peppercorns with salt in a small bowl.
• Place beef tenderloin on a rack set on top of a heavy, rimmed baking sheet. Rub butter mixture over the tenderloin, coating well. Pat peppercorn mixture into the butter. Cover and refrigerate for 3 to 24 hours.
• Mix sour cream, remaining 3 tablespoons Dijon, and horseradish together in a small container. Cover and chill for 3 hours.
• When ready to cook, preheat the oven to 350 degrees F (175 degrees C).
• Uncover tenderloin and bake in the preheated oven until firm and reddish-pink and juicy in the center, about 1 hour. An instant-read thermometer inserted into the center should read between 135 and 140 degrees F (57 and 60 degrees C) for medium-rare/medium.
• Transfer to a serving platter and loosely cover with foil. Let rest 10 minutes before slicing.
• Serve with the sour cream-horseradish sauce.
