This simplified Beef Wellington wraps tender beef, savory mushroom duxelles, and prosciutto in flaky puff pastry. Elegant, make-ahead friendly, and perfect for holidays or date night.
Preheat oven to 425°F. Line a sheet pan with parchment.
Pat the beef dry. Season all over with salt and pepper.
Heat olive oil and 1 tbsp butter in a skillet until shimmering.
Sear beef on all sides until well browned, about 6–8 minutes total. Cool completely.
Brush the cooled beef with Dijon. Wrap tightly in plastic and chill 20 minutes.
Pulse mushrooms, shallot, and garlic until finely chopped, not pureed.
Melt remaining butter over medium heat. Cook mushroom mixture with thyme until very dry.
Season duxelles lightly with salt and pepper. Cool fully to room temperature.
On plastic wrap, shingle prosciutto into a rectangle slightly larger than the beef.
Spread duxelles evenly over prosciutto. Place beef along one edge and roll into a tight log.
Twist the plastic ends to compress. Chill the log 20 minutes to set the shape.
Dust the counter with flour. Roll pastry into a thin rectangle, about 1/8 inch thick.
Unwrap the beef. Set on pastry. Wrap tightly, sealing seams and tucking ends under.
Chill 15 minutes. Whisk egg with water and brush all over the pastry.
Score lightly with a knife and cut two small vents on top. Sprinkle a pinch of salt.
Bake until pastry is deep golden and center reads 125–130°F, about 35–40 minutes.
Rest 10 minutes before slicing thickly. Serve immediately.
Notes
Variation: Add a thin layer of pâté or brush the duxelles with a spoonful of Madeira for extra richness. Make-ahead: Assemble up to 24 hours in advance, keep chilled, and bake straight from the fridge, adding a few minutes. Serve with a quick pan jus or a peppercorn sauce.This recipe is an original creation inspired by classic Easy Beef Wellington Recipe flavors.
