BEST BEEF WELLINGTON RECIPE RECIPES

Steps:

• For the mushroom mixture: In the bowl of a food processor, in two batches, pulse the mushrooms and shallots, until finely chopped, 12 to 15 times, stopping occasionally to scrape the sides of the bowl.
• Heat the olive oil in a large skillet over medium heat. Add the mushroom mixture. Cook, stirring often, until tender, beginning to brown and any moisture in the skillet has evaporated, 25 to 30 minutes. Add the garlic, thyme, salt and pepper. Cook, stirring often, for 1 minute. Stir in the parsley and remove from the heat. Let cool to room temperature, at least 30 minutes.
• For the Beef Wellington: Sprinkle the beef tenderloin all over with salt and pepper. In a large skillet over medium-high, heat the oil. Cook the beef tenderloin, turning occasionally, until browned on all sides, 10 to 12 minutes total. Remove the tenderloin from the skillet and set aside to cool for 30 minutes. Remove and discard the twine.
• On a clean work surface, overlap 2-3 pieces of plastic wrap to form a 22 x 18-inch rectangle. Lay the prosciutto slices on the plastic wrap, slightly overlapping each slice to form a 13 x 10 -inch rectangle in the center of the plastic wrap. Spread the cooled mushroom mixture evenly over the prosciutto. Rub the beef tenderloin all over with mustard and arrange lengthwise along the bottom third of the prosciutto rectangle. Using the plastic wrap as a guide, roll the beef tenderloin in the mushroom covered prosciutto to form a log. Wrap tightly in plastic wrap and chill at least 1 hour or up to 4 hours.
• Preheat the oven to 425°F. On a lightly floured surface, slightly overlap the 2 sheets of puff pastry and roll into a 15x12 -inch rectangle. Lightly brush the top third of a long side of the pastry with egg. Remove the plastic wrap from the beef tenderloin log and place the log lengthwise in the center of the puff pastry. Fold to completely seal the log in pastry, brushing any folds with egg to help them stick together and seal.
• Place the pastry wrapped tenderloin, seam side down, on a parchment-lined rimmed baking sheet. Brush the log lightly with the remaining egg. Using a small knife, cut 3 (1-inch) slits in the puff pastry to allow steam to escape. 
• Bake the Beef Wellington until the puff pastry is golden brown and a meat thermometer inserted in the center registers 120°F for medium-rare, 40 to 50 minutes, tenting with foil to prevent excess browning if needed. Remove from the oven and let rest at room temperature for about 15 minutes before serving.

Steps:

• 1. Preheat a large frying pan on a high heat. Rub the beef all over with sea salt and black pepper. Pour a good lug of oil into the pan, then add the beef, 1 knob of butter and 1 sprig of rosemary.
  2. Sear the beef for 4 minutes in total, turning regularly with tongs, then remove to a plate.
  3. Wipe out the pan and return to a medium heat. Peel the onion and garlic, then very finely chop with the mushrooms and put into the pan with the remaining knob of butter and another lug of oil.
  4. Strip in the rest of the rosemary leaves and cook for 15 minutes, or until soft and starting to caramelise, stirring regularly.
  5. Toss the livers and Worcestershire sauce into the pan and cook for another few minutes, then tip the contents onto a large board and drizzle with the truffle oil (if using).
  6. Finely chop it all by hand with a big knife, to a rustic, spreadable consistency. Taste and season to perfection, then stir in the breadcrumbs (you can use pancakes to line the pastry and absorb the juices, but I prefer using breadcrumbs like this).
  7. Preheat the oven to 210°C/425°F/gas 7.
  8. On a flour-dusted surface, roll out the pastry to 30cm x 40cm. With one of the longer edges in front of you, spread the mushroom pâté over the pastry, leaving a 5cm gap at either end and at the edge furthest away from you – eggwash these edges.
  9. Sit the beef on the pâté then, starting with the edge nearest to you, snugly wrap the pastry around the beef, pinching the ends to seal.
  10. Transfer the Wellington to a large baking tray lined with greaseproof paper, with the pastry seal at the base, and brush all over with eggwash (you can prep to this stage, then refrigerate until needed – just get it out 1½ hours before cooking so it’s not fridge-cold).
  11. When you’re ready to cook, heat the tray on the hob for a couple of minutes to start crisping up the base, then transfer to the oven and cook for 40 minutes for blushing, juicy beef – the two end portions will be more cooked, but usually some people prefer that.
  12. For the gravy, peel and roughly chop the onions and put into a large pan on a medium heat with a lug of oil and the thyme leaves. Cook for 20 minutes, stirring occasionally, then stir in the jam and simmer until shiny and quite dark.
  13. Add the Madeira, flame with a match, cook away, then stir in the mustard and flour, gradually followed by the stock. Simmer to the consistency you like, then blend with a stick blender and pass through a sieve, or leave chunky.
  14. Once cooked, rest the Wellington for 5 minutes, then serve in 2cm-thick slices with the gravy and steamed greens.
