Nobody knows exactly who invented this dish but today, it’s a culinary classic that combines tender beef with a pastry jacket.

Prep Time: 45mins / Cook Time: 1hr

Serves 4


  • Beef fillet (tenderloin) of around 1kg/2lb 4oz
  • 3 tbsp olive oil
  • 250g/ 9oz white button mushrooms, include some wild ones if you like.
  • 50g/ 2oz butter
  • 1 large sprig fresh thyme
  • 100ml/ 3½ fl oz dry white wine
  • 12 slices San Nicola Prosciutto
  • 500g/1lb 2oz pack puff pastry, thawed if frozen 
  • a little flour, for dusting
  • 2 egg yolks beaten with 1 tsp water


  • Heat oven to 220C (430°F). Sit the 1kg beef fillet on a roasting tray, brush with 1 tbsp olive oil and season with pepper, then roast for 15 minutes for medium rare or 20 minutes for medium. When the beef is cooked to your liking, remove from the oven to cool, then chill in the fridge for about 20 minutes.

  • While the beef is cooling, chop 250g mushrooms (and wild, if you like) as finely as possible so they have the texture of coarse breadcrumbs. You can use a food processor to do this, but make sure you pulse-chop the mushrooms so they don’t become a paste.

  • Heat 2 tablespoons of olive oil and 50g butter in a large pan and fry the mushrooms on a medium heat, with 1 large sprig fresh thyme or ½ tsp dry, for about 10 minutes stirring often, until you have a softened mixture. Season the mushroom mixture, pour over 100ml dry white wine and cook for about 10 minutes until all the wine has been absorbed. The mixture should hold its shape when stirred. Remove the mushroom duxelle from the pan to cool and discard the thyme.

  • Overlap two pieces of cling film over a large chopping board. Lay 12 slices prosciutto on the cling film, slightly overlapping, in a double row. Spread half the duxelles over the prosciutto, then sit the fillet on it and spread the remaining duxelle over. Use the cling film’s edges to draw the prosciutto around the fillet, and then roll it into a sausage shape, twisting the ends of cling film to tighten it as you go.

  • Chill the fillet while you roll out the pastry.

  • Dust your work surface with a little flour. Roll out a third of the 500g pack of puff pastry to an 18-x 30cm strip and place on a non-stick baking sheet. Roll out the remainder of the 500g pack of puff pastry to about 28 x 36cm. Unravel the fillet from the cling film and sit it in the centre of the smaller strip of pastry. Beat the 2 egg yolks with 1 tsp water and brush the pastry’s edges, and the top and sides of the wrapped fillet. Using a rolling pin, carefully lift and drape the larger piece of pastry over the fillet, pressing well into the sides. Trim the joins to about a 4cm rim. Seal the rim with the edge of a fork or spoon handle. Glaze all over with more egg yolk and, using the back of a knife, mark the beef Wellington with long diagonal lines taking care not to cut into the pastry. Chill for at least 30 minutes and up to 24 hrs.

  • Heat oven to 200°C (400°F). Brush the Wellington with a little more egg yolk and cook until golden and crisp – 20-25 minutes for medium-rare beef, 30 minutes for medium. Allow to rest for 10 minutes before slicing. Serve in thick slices.
