HOW DO YOU MAKE BEEF WELLINGTON RECIPES

Steps:

• Using kitchen twine, tie tenderloin in 4 places. Season generously with salt and pepper.
• Over high heat, coat bottom of a heavy skillet with olive oil. Once pan is nearly smoking, sear tenderloin until well-browned on all sides, including the ends, about 2 minutes per side (12 minutes total). Transfer to a plate. When cool enough to handle, snip off twine and coat all sides with mustard. Let cool in fridge.
• Meanwhile, make duxelles: In a food processor, pulse mushrooms, shallots, and thyme until finely chopped.
• To skillet, add butter and melt over medium heat. Add mushroom mixture and cook until liquid has evaporated, about 25 minutes. Season with salt and pepper, then let cool in fridge.
• Place plastic wrap down on a work surface, overlapping so that it’s twice the length and width of the tenderloin. Shingle the prosciutto on the plastic wrap into a rectangle that’s big enough to cover the whole tenderloin. Spread the duxelles evenly and thinly over the prosciutto.
• Season tenderloin, then place it at the bottom of the prosciutto. Roll meat into prosciutto-mushroom mixture, using plastic wrap to roll tightly. Tuck ends of prosciutto as you roll, then twist ends of plastic wrap tightly into a log and transfer to fridge to chill (this helps it maintain its shape).
• Heat oven to 425°. Lightly flour your work surface, then spread out puff pastry and roll it into a rectangle that will cover the tenderloin (just a little bigger than the prosciutto rectangle you just made!). Remove tenderloin from plastic wrap and place on bottom of puff pastry. Brush the other three edges of the pastry with egg wash, then tightly roll beef into pastry.
• Once the log is fully covered in puff pastry, trim any extra pastry, then crimp edges with a fork to seal well. Wrap roll in plastic wrap to get a really tight cylinder, then chill for 20 minutes.
• Remove plastic wrap, then transfer roll to a foil-lined baking sheet. Brush with egg wash and sprinkle with flaky salt.
• Bake until pastry is golden and the center registers 120°F for medium-rare, about 40 to 45 minutes. Let rest 10 minutes before carving and serving.

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.
