Method
- Pat beef dry and season generously with salt and pepper.
- Heat olive oil in a skillet over high heat and sear beef on all sides 2–3 minutes. Remove and brush with Dijon mustard. Let cool.
- Melt butter in the same skillet. Add shallots and garlic, sauté 1–2 minutes.
- Add mushrooms and thyme, cook until moisture evaporates and mixture becomes paste-like. Season with salt and pepper and let cool.
- Lay prosciutto on plastic wrap, spread mushroom duxelles over it, place beef on top, and roll tightly. Chill 15 minutes.
- Roll puff pastry to a rectangle, wrap beef roll, seal edges, brush with egg, and score top. Chill 10 minutes.
- Preheat oven to 425°F (220°C). Bake Wellington 25–30 minutes until pastry is golden and beef is medium-rare.
- Rest 10 minutes before slicing and serving.
Notes
Ensure beef and mushroom mixture are cooled before wrapping in pastry to prevent sogginess. Use high-quality puff pastry for best results.
