Method

  1. 01

    Make puff pastry dough, chill overnight

    20 min

    Can use store-bought frozen puff pastry to skip this and the laminating steps.

  2. 02

    Season and smoke tenderloin at 160°F for 90 min

    90 min

    Internal temp must not exceed 90°F. Refrigerate uncovered overnight after smoking.

  3. 03

    Laminate butter into dough (2 turns), chill 2 hours

    30 min

    Roll, fold butter into dough, do 2 turns, wrap and refrigerate.

  4. 04

    Sauté mushrooms and shallots until liquid evaporates

    18 min

    You're cooking out moisture here, not just softening — the filling needs to be completely dry or your pastry won't crisp up. When the pan looks almost wet at the start but totally dry at the finish, you're done.

  5. 05

    Deglaze with cognac, add cream, reduce until thick

    12 min

    Season with spices, cool completely in refrigerator before using.

  6. 06

    Do 2 more turns on puff pastry, roll out large rectangle

    20 min

    Roll to extend 3 inches beyond filet ends. Work quickly to keep pastry cold.

  7. 07

    Layer fillo, prosciutto, mushroom filling on film

    8 min

    Work methodically and keep your layers tight with no air pockets, or steam will blow through your pastry when it bakes. Film underneath keeps everything from sticking, and even overlap on the fillo so nothing unravels.

  8. 08

    Coat tenderloin with horseradish mixture, roll in fillo layer

    10 min

    Wrap tightly in film and refrigerate while rolling puff pastry.

  9. 09

    Preheat oven to 425°F

    15 min

    Use 400°F if convection.

  10. 10

    Wrap tenderloin in puff pastry, trim and seal ends

    8 min

    Place seam-side down on parchment-lined sheet pan.

  11. 11

    Egg wash, score top, sprinkle salt

    4 min

    One thin, even coat of egg wash gives you that mahogany color — don't puddle it or you'll get dark spots. Score shallow lines across the top for both looks and to help the heat penetrate, then a pinch of fleur de sel brings out the crust.

  12. 12

    Bake until golden and center reaches 115-125°F

    35 min

    Tent with foil if pastry browns too quickly. Internal temp will rise 8-10°F during rest.

  13. 13

    Rest Wellington for 10-15 minutes

    12 min

    This isn't just about temperature — it lets the pastry relax so it won't crack when you cut, and the meat stays hot enough to serve. You should feel the Wellington still warm to the touch but not piping hot.

  14. 14

    Slice ends, carve and plate

    5 min

    A sharp knife and one smooth motion per slice keeps the pastry from shattering and the layers from separating. Plate it cut-side up so people see that perfect pink beef and those golden, crispy layers.

From Mike's Notebook

01

Smoke the tenderloin to exactly 90°F internal—it'll coast to medium-rare when the pastry hits the oven.

02

Cool the mushroom dough completely in the fridge or it'll turn your puff pastry into soup.

03

Keep puff pastry cold between turns and rolling—warm dough won't laminate, just spreads into a greasy mess.
