Ingredients
Method
Preparation
- Season the beef filet generously with salt and pepper.
- Heat the olive oil in a hot pan over medium-high heat and sear the filet for 1 to 2 minutes on each side until a rich brown crust forms.
- Remove the filet from heat and brush with Dijon mustard while still warm.
- Finely chop the mushrooms and set them aside.
- In the same pan, melt butter and sauté garlic and thyme until fragrant.
- Add the mushrooms and cook until moisture is released and they become dry.
- Allow the mushroom mixture to cool completely.
Assembly
- Lay out prosciutto slices on a sheet of plastic wrap, overlapping slightly.
- Spread cooled mushroom mixture evenly over the prosciutto.
- Place the beef filet in the center and roll tightly using the plastic wrap.
- Chill in the refrigerator for 15 minutes to set the shape.
Baking
- Preheat your oven to 400°F (200°C).
- Roll out the puff pastry to encase the beef.
- Remove plastic wrap from the beef and place it in the center of the pastry.
- Wrap the pastry around the beef, sealing edges with egg wash and brush the top with more egg wash.
- Bake for 15 to 20 minutes until the pastry is golden brown.
- Let rest for 5 minutes before slicing.
Notes
Use a meat thermometer to check if the beef is cooked to your preferred doneness, aiming for 125°F (52°C) for medium-rare. Consider preparing the dish a day ahead and refrigerating until ready to bake.
