Herbed Beef Tenderloin

HERBED BEEF TENDERLOIN
Longhorn Steakhouse Recipe

Serves 10-12

1 whole beef tenderloin, 4-6 pounds
olive oil

Portabella Cream Sauce
1 tablespoon butter
2 cups sliced baby portabella mushrooms
1/2 cup chives
1/4 cup white wine
1 cup heavy cream
1 teaspoon garlic powder
2 teaspoons soy sauce
pinch of cayenne pepper
1/4 teaspoon each kosher salt & black pepper

Herb Rub
2 tablespoons fresh rosemary, finely chopped
2 tablespoons fresh thyme, finely chopped
1 tablespoon kosher salt
2 teaspoons ground black pepper
1 teaspoon onion powder
1 teaspoon garlic powder

To make the rub: In a small bowl mix the rub ingredients.

To cook the meat:  Have your butcher trim and discard the excess fat and silver skin from the tenderloin. Lay the tenderloin out with the smoothest side up. To ensure a consistent thickness on the grill, fold the tail end of the tenderloin under itself to form an even thickness. Tie the tenderloin snugly with butcher’s twine at 2-inch intervals and secure the folded end with two strings. Lightly coat the roast with oil. Season the roast all over with the herb rub.

Prepare the grill for direct and indirect cooking (450 degrees hot side; 250 degrees warm side)

Brush the cooking grates clean. Sear the tenderloin over the hot side for about 20 minutes, turning a quarter turn once every 4-5 minutes. Then slide the roast over to the warm side, loosely cover it with foil and cook until it reaches your desired doneness, 20 to 30 minutes for medium rare (125 to 130 degrees), turning once. Remove from the grill, loosely tent with foil, and let rest for 10 minutes. The temperature will rise 5 to 10 degrees during this time.

Snip and remove all the twine from the roast. Cut the meat crosswise into 1/2- to 1-inch slices and arrange onto a serving platter. Garnish with fresh rosemary sprigs and serve warm with the sauce.

To prepare the cream sauce, melt the butter in a saute pan.  Add the portabella mushrooms and saute for 3 minutes.  Add the white wine, soy sauce, salt, pepper, garlic powder and cayenne pepper.  Add heavy cream and stir to combine.  After 2 minutes add the chives.
