Luxurious beef fillet wrapped in mushroom duxelles and puff pastry, baked golden brown for an elegant main dish.

# What you need:

→ Beef

01 - 1 (2.5-3 lb) center-cut beef tenderloin, trimmed
02 - 2 tablespoons olive oil
03 - Salt and freshly ground black pepper

→ Mushroom Duxelles

04 - 1 lb cremini or button mushrooms, finely chopped
05 - 2 shallots, finely chopped
06 - 2 garlic cloves, minced
07 - 2 tablespoons unsalted butter
08 - 2 tablespoons fresh thyme leaves, chopped
09 - Salt and pepper, to taste

→ Prosciutto Layer

10 - 10-12 thin slices prosciutto

→ Assembly

11 - 1 lb puff pastry, thawed if frozen
12 - 1 egg, beaten for egg wash
13 - Flour, for dusting

→ Optional

14 - 2 tablespoons Dijon mustard

# Directions:

01 - Preheat oven to 425°F. Pat beef tenderloin dry and season generously with salt and pepper.
02 - Heat olive oil in large skillet over high heat. Sear beef on all sides until browned, about 2-3 minutes per side. Transfer to plate and let cool completely.
03 - In same skillet, melt butter over medium heat. Add shallots and garlic, cook until softened. Add mushrooms and thyme, season with salt and pepper, and cook until all moisture evaporates and mixture is dry, about 10-15 minutes. Cool completely.
04 - Lay large piece of plastic wrap on work surface. Arrange prosciutto slices, slightly overlapping, in rectangle large enough to wrap beef. Spread cooled mushroom duxelles evenly over prosciutto.
05 - Brush cooled beef tenderloin with Dijon mustard, if desired.
06 - Place beef on mushroom-covered prosciutto. Using plastic wrap, roll tightly into log, encasing beef in mushroom and prosciutto layer. Twist ends to seal and refrigerate for 20-30 minutes.
07 - On lightly floured surface, roll puff pastry into rectangle large enough to wrap beef. Unwrap beef log and place in center of pastry. Brush edges with egg wash.
08 - Fold pastry over beef, trimming excess and sealing seams. Place seam-side down on baking sheet lined with parchment paper. Brush pastry with egg wash and decorate with pastry scraps if desired.
09 - Chill wrapped Wellington for 15 minutes.
10 - Bake in preheated oven for 40-45 minutes, or until pastry is golden brown and instant-read thermometer inserted into center reads 122°F for rare, 129°F for medium-rare.
11 - Rest for 10-15 minutes before slicing and serving.

# Expert advice:

01 -
  • The contrast of textures, crispy pastry giving way to buttery soft beef, keeps every bite interesting
  • Making Wellington at home transforms a restaurant dish into something personal and deeply satisfying
02 -
  • Cold pastry and beef are essential, or the layers will slide apart while baking
  • The duxelles must be completely dry, or moisture will make the pastry soggy
03 -
  • Pat the beef extremely dry before searing for better browning
  • Chill the wrapped beef for at least 30 minutes for easier handling
