Préparation

1. 1

   --- BEEF TENDERLOIN ---

2. 2

   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.

3. 3

   Chill in the refrigerator, uncovered, for 12 hours (if time allows).

4. 4

   Let beef stand at room temperature for 1-2 hours before roasting.

5. 5

   Arrange oven rack to the middle of your oven and preheat to 430°F (220°C).

6. 6

   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.

7. 7

   Sear roasts on all four sides for about 3 minutes each side (about 12 minutes total), turning with tongs until well browned.

8. 8

   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.

9. 9

   Slather remaining garlic butter over each roast (about 2 tablespoons each).

10. 10

    Transfer skillet into the hot oven. (Alternatively: Transfer roast to a lightly greased roasting pan or baking dish.)

11. 11

    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 rare130-135°F for medium(Temperature will continue to rise about 5 degrees while the meat rests.)

12. 12

    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).

13. 13

    Carve the beef tenderloin into 1/2-inch-thick slices and serve the beef tenderloin with the optional red wine sauce.

14. 14

    --- RED WINE SAUCE ---

15. 15

    Skim fat off the remaining juices in the pan (if any).

16. 16

    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.

17. 17

    Add thyme/rosemary and season with pepper. Continue cooking for a further minute or so while stirring often.

18. 18

    Pour in red wine and cook until reduced by half.

19. 19

    Add in beef stock and bring to a boil. Reduce heat and simmer until reduced by half. Remove the sprig of thyme or rosemary.
