Classic Beef Wellingtons

Directions

1. 1
   Sprinkle steaks with 1/2 teaspoon salt and 1/4 teaspoon pepper. In a large skillet, brown steaks in 1 tablespoon oil for 2-3 minutes on each side. Remove from skillet and refrigerate until chilled.
2. 2
   In the same skillet, saute mushrooms and onion in remaining oil until tender. Stir in remaining salt and pepper; cool to room temperature.
3. 3
   Preheat oven to 425°. On a lightly floured surface, roll each puff pastry sheet into a 14x9-1/2-in. rectangle. Cut into two 7-in. squares (use scraps to make decorative cutouts if desired). Place a steak in the center of each square; top with mushroom mixture. Lightly brush pastry edges with water. Bring opposite corners of pastry over steak; pinch seams to seal tightly.
4. 4
   Place in a greased 15x10x1-in. baking pan. Cut four small slits in top of pastry. Arrange cutouts over top if desired. Brush with egg.
5. 5
   Bake 25-30 minutes or until pastry is golden brown and meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°).
