Instructions

  1. Put the tenderloin in a large food storage bag with 1/4 cup red wine, the 4 cloves of garlic (minced), Cajun seasoning, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Seal the bag and refrigerate for about 2 hours.
  2. Preheat the oven to 425 F.
  3. Lightly oil a large, shallow roasting pan.
  4. Put the potatoes, carrots, and onion in a bowl and toss with the minced garlic, 1/2 teaspoon salt, 1/8 teaspoon pepper, and 3 tablespoons olive oil.
  5. Arrange the vegetables in the prepared pan and cover with foil.
  6. Roast for 20 minutes.
  7. Meanwhile, heat 1 tablespoon olive oil and 1 tablespoon butter in a medium saucepan over low heat; add the sliced shallots and cook until lightly browned., stirring frequently. Add the beef stock and red wine; bring to a boil. Reduce heat to medium-low and simmer for about 15 minutes, or until reduced by about one-third to one-half.
  8. Pour the marinade off the beef and add it to the sauce. Simmer for 2 minutes longer. Set aside and keep warm.
  9. Remove the foil from the vegetables; place the beef tenderloin on top. Roast uncovered for about 1 hour to 1 hour and 15 minutes, until the beef registers about 145 F on a meat thermometer for medium, or to about 135 F for medium rare.
  10. Place the beef on a cutting board and tent loosely with foil. Let the tenderloin stand for about 10 minutes.
  11. Slice tenderloin and serve with the red wine sauce and vegetables.
