Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Rub 1.5 pounds trimmed beef tenderloin with 2 tablespoons Dijon mustard and season with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
  2. Step 2: Sauté 4 ounces finely chopped mushrooms in 2 tablespoons butter with 1 tablespoon chopped thyme until reduced to a paste (about 10 minutes), then spread evenly over the mustard-coated beef.
  3. Step 3: Wrap beef tightly with 4 ounces prosciutto slices, pressing gently to adhere, then place on a sheet of puff pastry. Roll pastry around beef, sealing edges with beaten egg.
  4. Step 4: Place seam-side down on a baking sheet, brush with 1 beaten egg, and bake for 25-30 minutes until pastry is golden and beef reaches 125°F (52°C) for medium-rare.
