- Finely chop mushrooms (or pulse in food processor).
- In a skillet over medium heat, add butter, shallots, and garlic.
- Cook until softened.
- Add mushrooms, thyme, salt, and pepper.
- Cook until ALL liquid evaporates — about 8–10 minutes.

Step 3: Wrap the Filets in Prosciutto & Duxelles
- Lay plastic wrap on the counter.
- Place 1 slice of prosciutto down.
- Spread a thin layer of mushroom duxelles on it.
- Place a filet on top and wrap tightly using the plastic wrap.

Step 4: Prepare the Puff Pastry
- Preheat oven to 400°F (200°C).
- Cut the puff pastry into 4 equal squares.
- Remove plastic wrap from wrapped filets.
- Place each on a pastry square.
- Fold pastry over like a present — trim excess.
- Seal edges well.
- Place seam-side down on a parchment-lined baking sheet.
- Brush with beaten egg for a golden finish.
- Score the pastry lightly with a knife for decoration.
Step 5: Bake
- Bake at 400°F (200°C) for:
- 12–14 minutes (rare–medium rare)
- 15–17 minutes (medium)
- Use a thermometer:
- 120–125°F = rare
- 130–135°F = medium rare
