# What You Need:
→ Beef
01 - 2 lb beef tenderloin, trimmed
02 - Salt and freshly ground black pepper to taste
03 - 2 tablespoons vegetable oil
→ Mushroom Duxelles
04 - 1 lb cremini or button mushrooms, finely chopped
05 - 2 shallots, minced
06 - 2 cloves garlic, minced
07 - 2 tablespoons unsalted butter
08 - 2 tablespoons fresh thyme leaves, chopped

→ Assembly
10 - 10 slices prosciutto
11 - 2 tablespoons Dijon mustard
12 - 1 sheet puff pastry, approximately 14 oz, thawed if frozen
13 - 1 large egg, beaten for egg wash
14 - Flour for dusting
# How to Make It:
01 - Preheat oven to 425°F
02 - Season beef tenderloin with salt and pepper. Heat vegetable oil in heavy skillet over high heat. Sear beef on all sides for approximately 2 minutes per side until browned. Remove from heat and allow to cool completely
03 - In same skillet, melt butter over medium heat. Add minced shallots and garlic, sauté for 1 minute. Add chopped mushrooms and thyme, season with salt and pepper. Cook until all moisture evaporates and mixture reaches paste-like consistency, approximately 10 minutes. Allow to cool
04 - Lay plastic wrap on work surface. Arrange prosciutto slices in slightly overlapping layer to form rectangle slightly larger than beef
05 - Spread cooled mushroom duxelles evenly over prosciutto layer
06 - Brush cooled beef with Dijon mustard. Place beef on duxelles-covered prosciutto
07 - Using plastic wrap, roll prosciutto and mushrooms around beef into tight log. Twist ends to seal and refrigerate for 20 minutes
08 - Roll out puff pastry on floured surface to rectangle large enough to fully encase beef. Unwrap beef from plastic and place in center of pastry. Fold pastry over beef, trim excess, and seal edges. Place seam-side down on parchment-lined baking sheet
09 - Brush pastry with beaten egg wash. Decorate with pastry scraps if desired. Refrigerate for 10 minutes
10 - Bake for 40 to 45 minutes until pastry is golden and instant-read thermometer inserted into beef reads 120°F for rare or 130°F for medium-rare
11 - Remove from oven and allow to rest for 10 to 15 minutes before slicing
