A new take on the classic English dish!
- 1 beef tenderloin (2 to 2 1/2 pounds)
- ground black pepper (optional)
- 1 Pepperidge Farm® Puff Pastry Sheet, thawed
- 1 egg
- 1 Tbsp water
- 1 Tbsp butter
- 2 cup finely chopped mushroom
- ½ cup medium onion, finely chopped
- Heat the oven to 425°F. Place the beef into a lightly greased roasting pan. Season with the black pepper, if desired. Roast for 30 minutes or until a meat thermometer reads 130°F. Cover the pan and refrigerate for 1 hour.
- Reheat the oven to 425°F. Beat the egg and water in a small bowl with a fork or whisk.
- Heat the butter in a 10-inch skillet over medium-high heat. Add the mushrooms and onion and cook until the mushrooms are tender and all the liquid is evaporated, stirring often.
- Unfold the pastry sheet on a lightly floured surface. Roll the pastry sheet into a rectangle 4 inches longer and 6 inches wider than the beef. Brush the pastry sheet with the egg mixture. Spoon the mushroom mixture onto the pastry sheet to within 1-inch of the edges. Place the beef in the center of the mushroom mixture. Fold the pastry over the beef and press to seal. Place seam-side down onto a baking sheet. Tuck the ends under to seal. Brush the pastry with the egg mixture.
- Bake for 25 minutes or until the pastry is golden brown and a meat thermometer reads 140°F.
