Method
Sear the Beef:
- Pat the tenderloin dry and season it all over with salt and pepper. Heat the olive oil in a large skillet over high heat.
- Sear the beef on all sides, about 1 minute per side, until browned. Brush with Dijon mustard and transfer to a plate to cool.
Cook the Duxelles:
- Melt the butter in the skillet over medium heat. Add the shallot and cook for 2 minutes.
- Add the mushrooms, garlic, thyme, and remaining salt. Cook, stirring often, until the mushrooms release and then lose all their moisture.
- Add the wine and cook until the pan is dry. Spread the duxelles on a plate and cool completely.
Wrap and Bake:
- Lay plastic wrap on the counter and arrange the prosciutto in a slightly overlapping rectangle. Spread the cooled duxelles over it.
- Place the beef in the center and use the plastic wrap to roll the prosciutto tightly around it. Chill for 15 minutes.
- Roll the puff pastry into a rectangle large enough to enclose the beef. Unwrap the beef, place it on the pastry, and seal the edges. Chill for 30 minutes.
- Heat the oven to 425 F (220 C). Brush the pastry with egg wash, score lightly, and bake for 35 to 45 minutes, until golden and the center reaches the desired temperature.
- Rest for 15 minutes before slicing thickly and serving.
Nutrition
Notes
- The mushrooms must be cooked dry or their moisture will soften the pastry.
- Chilling the wrapped beef helps the pastry hold its shape in the oven.
- Use the thermometer in the side of the Wellington so the temperature reading reflects the center.
