Classic Beef Wellington
A showstopper British roast: seared centre-cut beef fillet wrapped in mushroom duxelles and prosciutto, all encased in golden puff pastry. Crisp outside, juicy pink centre — perfect for special occasions.
Beef Wellington is the culinary equivalent of putting on your best suit: impressive, a little fussy, and absolutely worth it. This classic British centrepiece wraps a tender fillet in a savoury mushroom duxelles and salty prosciutto, all hugged by crisp puff pastry.
Make this for a dinner party or a holiday roast when you want a dramatic main that still tastes of proper beef. Follow the critical steps — especially drying the mushrooms and using a thermometer — and you’ll be rewarded with a perfect pink centre and golden pastry every time.

Instructions
Bring the beef to room temperature: pat dry with kitchen paper, season all over with 1½ tsp sea salt and plenty of black pepper.
Heat a heavy frying pan over high heat. Add 1 tbsp olive oil and 1 tbsp butter. When smoking hot, sear the fillet on all sides (including ends) until well browned — about 2 minutes per side. Transfer to a plate to cool, then brush all over with English mustard.
Make the duxelles: finely chop the mushrooms (food processor pulse or very sharp knife). In the same pan, add remaining 1 tbsp olive oil and 1 tbsp butter over medium heat. Add shallots and cook 2–3 minutes until soft, add garlic and cook 30 seconds. Add mushrooms and thyme, then sauté until all moisture has evaporated and mixture is paste-like — about 10–12 minutes. Stir in wine/brandy if using and cook until evaporated. Season lightly.
Cool the duxelles quickly on a plate or tray (spread thin) so it stops cooking, then mix in pâté if using. Chill for 10 minutes until just cool.
Lay a large sheet of clingfilm on the worktop. Arrange the prosciutto slices slightly overlapping in a rectangle (large enough to wrap the fillet). Spread the cooled duxelles in an even layer over the prosciutto (leave a little edge). Place the mustard-coated fillet at one end and, using the clingfilm, roll the prosciutto around the fillet into a tight sausage. Twist the ends of the clingfilm and chill on a tray for 30 minutes to firm up.
Preheat the oven to 200°C / 180°C fan / 400°F / gas 6. Lightly flour your work surface and roll the puff pastry to give a rectangle large enough to encase the beef (about 30x35cm). Beat the egg with cold water to make the egg wash.
Unwrap the prosciutto-wrapped fillet and place it in the centre of the pastry. Brush the pastry edges with egg wash. Fold the pastry around the fillet, sealing the seams and trimming any excess. Place the seam-side down on a baking sheet lined with parchment. Trim ends neatly, brush with more egg wash, and chill for 15 minutes.
Lightly score the pastry for decoration (don’t cut through). Brush again with egg wash. Make a few small steam slits if desired. Place in the preheated oven and bake for 30–40 minutes (depending on oven and thickness). Start checking internal temp after 25 minutes.
When the pastry is golden and the internal temp is 50–54°C, remove from oven and rest on a board for 10–15 minutes before slicing. Resting lets juices redistribute and finish cooking gently.
Slice into 3–4 thick slices and serve garnished with parsley or microgreens. Finish with extra black pepper if you like.
Tips
- Dry the duxelles thoroughly — cook the mushrooms until the pan is almost dry. Any excess moisture will steam the pastry and make it soggy.
- Chill between key stages: after searing and after wrapping in prosciutto, then again once in pastry. Chilled, firm layers are much easier to handle and bake evenly.
- Use an instant-read thermometer to check doneness. Aim for 50–54°C for medium-rare; the carry-over resting time will raise it a few degrees.
- If you don’t have a food processor, finely chop mushrooms and spread them thinly in the pan so they release and then lose moisture quickly.
- Make-ahead: complete through step 5 (prosciutto-wrapped fillet), clingfilm-wrap and chill up to 24 hours. Roll in pastry and bake on the day.

FAQ
Can I make Beef Wellington ahead of time?
Yes — you can prepare up to and including the prosciutto-wrapped fillet (step 5), clingfilm and refrigerate up to 24 hours. Roll in pastry and bake on the day for best results.
What internal temperature should I aim for?
Pull from the oven at 50–54°C (122–129°F) for medium-rare. It will rise a few degrees while resting. For medium aim for 55–58°C.
Why did my pastry go soggy?
Usually because the duxelles was too wet or the beef wasn’t properly chilled before wrapping. Cook the mushrooms until dry, and chill wrapped components so they’re firm before enclosing in pastry.
Can I freeze Beef Wellington?
You can freeze the assembled, unbaked Wellington (wrapped) for up to 1 month. Bake from frozen adding ~15–25 minutes, but results are marginally less crisp than baking from chilled.
