Savory Roast Beef Tenderloin with Porcini Mushroom Sauce

Follow our step-by-step guide on how to make Savory Roast Beef Tenderloin with Porcini Mushroom Sauce.

1. Step 1

   To start, take a bowl and combine your dried porcini mushrooms with warm water.

2. Step 2

   Let them soak for about an hour until they’re nice and soft.

3. Step 3

   Once they’re ready, drain the mushrooms, making sure to keep the soaking liquid, and then chop them into small pieces.

4. Step 4

   Set both the diced mushrooms and the reserved liquid aside for later use.

5. Step 5

   Now, preheat your oven to a cozy 325°F (165°C) to get it ready for the deliciousness to come.

6. Step 6

   Next, it’s time to season your beef tenderloin generously with salt and black pepper.

7. Step 7

   In a large ovenproof skillet, heat up some vegetable oil over high heat.

8. Step 8

   When the oil is shimmering, add the beef and sear it until it’s beautifully browned on all sides, which should take about 5 to 8 minutes per side.

9. Step 9

   This step is crucial for locking in those rich flavors! Once your beef is perfectly seared, lower the heat to medium and toss in a tablespoon of butter along with the sliced shallots and a pinch of salt.

10. Step 10

    Sauté these until the shallots become soft and translucent, which should take around 5 to 7 minutes.

11. Step 11

    The aroma will be irresistible! Now, pour in the tarragon vinegar and bring it to a boil, making sure to scrape up any delicious browned bits from the bottom of the skillet.

12. Step 12

    Let this simmer until the liquid reduces by half, which will take about 2 to 4 minutes.

13. Step 13

    This reduction adds depth to your sauce, enhancing the overall flavor.

14. Step 14

    Next, stir in the veal stock, heavy cream, half a cup of the reserved mushroom liquid, the diced mushrooms, and season with additional salt and pepper to taste.

15. Step 15

    Mix everything together well, and then gently return the beef to the skillet, nestling it into that rich sauce.

16. Step 16

    Now it’s time for the oven! Transfer the skillet to your preheated oven and roast the beef until it reaches a perfect medium-rare doneness, which should take about 45 minutes.

17. Step 17

    To check, use an instant-read thermometer; it should read 130°F (54°C) when inserted into the center.

18. Step 18

    Once it’s done, carefully transfer the beef to a plate and loosely cover it with foil to let it rest.

19. Step 19

    This resting period is essential for juicy, tender meat.

20. Step 20

    While the beef is resting, place the skillet back on high heat to bring those pan juices to a boil.

21. Step 21

    Stir in the remaining tablespoon of butter and the chopped tarragon, seasoning with salt and pepper to taste.

22. Step 22

    Finally, return the tenderloin along with any juices that have accumulated back to the skillet, allowing it to soak up all that flavor.

23. Step 23

    Serve your beautifully roasted beef hot, and enjoy the delightful combination of flavors that will surely impress your family and friends!.
