Roast Beef Tenderloin

Ingredients

• 0.33 cups dried porcini mushrooms
• 1 cup warm water
• 2.5 pounds trimmed beef tenderloin roast , tied
• salt and ground black pepper to taste
• 1 tablespoon vegetable oil
• 1 tablespoon unsalted butter
• 0.5 cups sliced shallots
• 1 pinch salt
• 0.25 cups tarragon vinegar
• 1 cup veal stock
• 0.25 cups heavy cream
• 1 tablespoon unsalted butter
• 1 tablespoon chopped fresh tarragon
• salt and ground black pepper to taste

Instructions

1. 1

   Combine porcini mushrooms and water in a bowl; soak until soft, 1 hour. Drain and reserve liquid. Dice and set mushrooms and reserved liquid aside.

2. 2

   Preheat oven to 325 degrees F (165 degrees C).

3. 3

   Season beef generously with salt and pepper. Heat vegetable oil in a large ovenproof skillet over high heat. Place beef in the skillet; cook until brown on all sides, 5 to 8 minutes per side.

4. 4

   Reduce heat to medium and stir in 1 tablespoon butter, shallots, and a pinch of salt; cook until shallots are soft and translucent, 5 to 7 minutes.

5. 5

   Pour tarragon vinegar into the skillet and bring to a boil while scraping any browned bits off of the bottom. Stir until liquid is reduced by half, 2 to 4 minutes.

6. 6

   Pour in veal stock, cream, 1/2 cup reserved mushroom liquid, mushrooms, salt, and pepper; stir to combine. Return beef to the skillet.

7. 7

   Roast in the preheated oven until meat is medium rare, about 45 minutes. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C). Transfer meat to a plate and loosely tent with foil. Set skillet over high heat and bring pan juices to a boil.

8. 8

   Stir in 1 tablespoon butter and tarragon; season with salt and pepper to taste. Return tenderloin and any accumulated juices to skillet and serve.
