Mushroom Duxelles Beef Wellington

Mushroom Duxelles Beef Wellington

This Beef Wellington combines crisp buttery pastry, savoury mushroom duxelles and tender beef fillet for a true centrepiece dish. With proper chilling between stages and a good rest after baking, you get clean slices and a beautifully cooked middle.

Method

40m45m1h 25m
  1. Season the beef fillet with salt and pepper. Sear in hot oil on all sides for 1 to 2 minutes per side until browned, then remove and brush all over with Dijon mustard while warm. Chill.
  2. For the duxelles, cook mushrooms, shallots, garlic, thyme and butter in a wide hob pan over medium-high heat for 12 to 15 minutes until all moisture evaporates and mixture becomes paste-like. Cool completely.
  3. Lay cling film on the counter and overlap prosciutto into a rectangle. Spread cooled duxelles evenly over it.
  4. Place beef on top and use cling film to roll tightly into a cylinder. Chill for 20 minutes to firm up.
  5. Roll pastry large enough to wrap beef. Remove cling film from beef roll, place on pastry seam-side down, and wrap tightly. Trim excess, seal edges, and chill 15 minutes.
  6. Brush with egg glaze, score lightly for decoration, and chill again while oven heats.
  7. Bake at 200°C (180°C fan) for 35 to 45 minutes until pastry is deep golden and internal temperature reaches your preferred doneness (about 48–52°C for medium-rare).
  8. Rest for 10 to 15 minutes before slicing to keep juices in and pastry crisp.

  • 10 slices Prosciutto thinly sliced

  • 2 Shallots finely chopped
  • 900 g Beef Fillet centre-cut piece
  • 25 g Unsalted butter

Notes

Cook the duxelles until very dry to avoid soggy pastry.
Chilling at each stage helps hold shape and improves pastry lift.
Use a thermometer for consistent doneness in the beef centre.
