Fillet of Beef with Tarragon Wine Sauce

3 1/2 pounds sirloin steak
1 3/4 tablespoons olive oil
1/2 teaspoon salt
1/4 teaspoon ground black pepper
1/3 cup butter
4 tablespoons Dijon mustard
1/2 cup chopped green onion
1 2/3 cups white wine
3 tablespoons tarragon
2 tablespoons heavy cream
1/4 teaspoon salt
1/8 teaspoon ground black pepper

1. Rub sirloin steak with olive oil, then season with salt and pepper.
2. Preheat oven to 550°F (285°C).
3. Roast steak in a large roasting pan, for 25 minutes, or until a meat thermometer registers 130°F (55°C) for medium rare. Transfer to a platter and let stand, loosely covered with aluminum foil, for 15 minutes.
4. In a bowl, cream together butter and Dijon mustard.
5. In a large saucepan combine chopped green onions, white wine, and tarragon. Cook the mixture over medium-high heat until the wine is reduced to about 1 cup.
