• 1 - Sear the Beef:
  Preheat oven to 200°C (390°F). Sear the beef tenderloin in a hot pan for 2-3 minutes per side until browned. Season with salt and pepper.
• 2 - Prepare Mushroom Duxelles:
  In the same pan, melt butter and add finely chopped mushrooms. Cook until moisture evaporates. Stir in thyme, salt, and pepper.
• 3 - Assemble the Wellington:
  Lay out prosciutto slices on a sheet of cling film. Spread mushroom mixture on top, place the beef in the center, and roll tightly.
• 4 - Wrap in Pastry:
  Roll out puff pastry and place the beef roll at one end. Wrap tightly and seal edges. Brush with egg yolk for shine.
• 5 - Bake the Wellington:
  Place on a baking sheet and bake in preheated oven for 25-30 minutes until golden brown. Let rest before slicing.
