Ingredients

• For the beef:
• 1-2 pounds beef tenderloin
• 2 tablespoons butter at room temperature
• 1 garlic clove
• 1 tablespoon whole grain or Dijon mustard
• ¼ teaspoon salt
• 1/8 teaspoon pepper
• 3 sprigs of rosemary
• For the Red Wine Mushroom Sauce:
• 2 tablespoons butter
• 8 ounces sliced Cremini mushrooms
• ¼ cup red wine (Merlot or Cabernet)
• ¼ cup beef or vegetable stock
• 1 teaspoon flour
• 2 tablespoons heavy cream
• ¼ teaspoon whole grain or Dijon mustard

Directions

• Heat oven to 250 degrees. Either finely chop the garlic or crush it with a garlic press. Place the beef in the center of a roasting pan on top of the sprigs of rosemary. Spread the butter, garlic, and mustard evenly over the beef. Sprinkle the salt and pepper over.
• Place the beef on a center rack in the oven to roast. For medium rare beef, you want to roast the beef until it reaches 125 degrees before you sear it. The cooking time will depend on the size of the beef tenderloin, but it took about 1 hour and 20 minutes for a 2-pound beef tenderloin to reach 125 degrees. The key is to keep your eye on the temperature of the meat; this is the time to use an in-oven digital thermometer if you have one.
• While the beef is cooking, sauté the mushrooms for the red wine sauce. Heat 1 tablespoon of butter in a skillet over medium heat low. Once the butter has melted, added the mushrooms and dust with a bit of salt and pepper. Stir to evenly distribute the butter, and add the red wine. Sauté the mushrooms until half of the liquid has been absorbed. Then set aside for later.
• Once the beef reaches 125 degrees, increase the temperature of the oven to broil (or high broil if you oven has multiple broil settings). Broil the beef for 2-4 minutes, keeping a close eye on the beef. You want a slight crust to form on the beef.
• Place the beef on a platter and let it rest while you prepare the sauce. It is important to let the beef rest before slicing it. This way the beef will lose less juice, resulting in more flavorful meat.
• To prepare the red wine sauce, scrape up any brown bits from the pan you used to roast the beef and pour them and any juice into a small saucepan. You can discard the rosemary. Heat the saucepan over medium heat, and add a tablespoon of butter and whisk in 1 teaspoon of flour. Once combined, pour in ¼ cup stock, 2 tablespoons cream, and ¼ teaspoon mustard. Mix and let slowly bubble for 1 minute, and then add the sautéed mushrooms and the liquid with them. Stir together until warm. Note: If the sauce is too thin, mix 1 teaspoon of melted butter with 1 teaspoon flour and add it to the sauce, let bubble and thicken for 1 minute (if the sauce is too thick add extra stock).
• Slice the beef into pieces 1 inch thick and serve with the red wine mushroom sauce.
