Ingredients

TENDERLOIN:

  • 5-6 pounds (2.5-3 kg) beef tenderloin, trimmed
  • 3 teaspoons coarse salt
  • 1 1/2 teaspoons fresh cracked black pepper
  • 2 tablespoons canola or vegetable oil
  • 1/2 cup unsalted butter, divided
  • 4 large cloves garlic, minced
  • 1/2 teaspoon Dijon mustard (optional)

RED WINE SAUCE:

  • 2 tablespoons vegetable or canola oil
  • 1 onion (or brown shallots) finely chopped
  • 1 1/2 cups (375 ml) dry red wine (Merlot or Pinot Noir)
  • 2 cups (500 ml) beef stock or broth
  • 1 sprig fresh thyme or rosemary
  • 1/8 teaspoon ground black pepper
  • 1/4 teaspoon salt

Instructions

BEEF TENDERLOIN

  • Slice tenderloin in half crosswise to create 2 smaller roasts. If roast is untied, fold ends up against the centre/thicker part of each roast and tie with kitchen twine spaced about 1-inch apart. Make sure each halve is even in thickness.
  • Chill in the refrigerator, uncovered, for 12 hours (if time allows).
  • Let beef stand at room temperature for 1-2 hours before roasting.
  • Arrange oven rack to the middle of your oven and preheat to 430°F (220°C).
  • Season each beef tenderloin roast all over with salt and pepper. Heat the oil in an oven-proof skillet over medium-high heat until hot.
  • Sear roasts on all four sides for about 3 minutes each side (about 12 minutes total), turning with tongs until well browned.
  • Combine butter, garlic and Dijon (if using) together in a small bowl while roasts are searing. Set one half of the butter mixture aside to use later for the sauce.
  • Slather remaining garlic butter over each roast (about 2 tablespoons each).
  • Transfer skillet into the hot oven. (Alternatively: Transfer roast to a lightly greased roasting pan or baking dish.)
  • Roast until an instant-read thermometer inserted into the thickest part registers 120-125°F for medium rare (about 20-25 minutes). *Or cook to your liking: 
    115-120°F for rare
    130-135°F for medium
    (Temperature will continue to rise about 5 degrees while the meat rests.)
  • Transfer the roast to a carving board and let rest for 15 minutes. Keep the juices in the pan to make the sauce (see below).
  • Carve the beef tenderloin into 1/2-inch-thick slices and serve the beef tenderloin with the optional red wine sauce.

RED WINE SAUCE

  • Skim fat off the remaining juices in the pan (if any).
  • Heat oil in the same pan with remaining pan juices over medium-high heat. Sauté onion for about 3 minutes until lightly browned and softened, scraping up any browned bits left from the beef.
  • Add thyme/rosemary and season with pepper. Continue cooking for a further minute or so while stirring often.
  • Pour in red wine and cook until reduced by half.
  • Add in beef stock and bring to a boil. Reduce heat and simmer until reduced by half. Remove the sprig of thyme or rosemary.
  • Season with salt to taste and whisk in reserved garlic butter. Pour in any juices left over from the resting steaks just before serving.
    OPTIONAL FOR A SMOOTH AND SILKY SAUCE: strain sauce through a sieve and discard the onion before serving.
