- Using kitchen twine, tie tenderloin in 4 places. Season generously with salt and pepper.
- Heat skillet and grease with olive oil. Once the pan is nearly smoking, sear tenderloin until well-browned on all sides, including the ends, about 1 1/2 minutes per side (9 minutes total). When cool enough to handle, snip off twine and coat all sides with mustard. Let cool in the fridge.
- Meanwhile, make duxelles: In a food processor, pulse mushrooms, shallots, and thyme until finely chopped.
- To skillet, add butter and melt over medium heat. Add mushroom mixture and cook until liquid has evaporated about 25 minutes. Season with salt and pepper, then let cool in the fridge.
- Place plastic wrap down on a work surface, overlapping so that it’s twice the length and width of the tenderloin. Shingle the prosciutto on the plastic wrap into a rectangle that’s big enough to cover the whole tenderloin. Spread the duxelles evenly and thinly over the prosciutto.
- place it at the bottom of the prosciutto. Roll meat into prosciutto-mushroom mixture, using plastic wrap to roll tightly. Tuck ends of prosciutto as you roll, then twist ends of plastic wrap tightly into a log and transfer to fridge to chill (this helps it maintain its shape).
- Heat oven to 425°. Lightly flour your work surface, then spread out puff pastry and roll it into a rectangle that will cover the tenderloin (just a little bigger than the prosciutto rectangle you just made!). Remove tenderloin from plastic wrap and place on the bottom of puff pastry. Brush the other three edges of the pastry with egg wash, then tightly roll beef into pastry.
- Once the log is fully covered in puff pastry, trim any extra pastry, then crimp edges with a fork to seal well. Wrap roll in plastic wrap to get a really tight cylinder, then chill for 20 minutes.
- Remove plastic wrap, then transfer roll to a foil-lined baking sheet. Brush with egg wash and sprinkle with flaky salt.
- Bake until pastry is golden and the center registers 120°F for medium-rare, about 40 to 45 minutes. Let rest 10 minutes before carving and serving.
