12 Best Beef Wellington Sides Recipes

Steps:

• For the Duxelles:
• To make the Duxelles: Add mushrooms, shallots, garlic, and thyme to a food processor and pulse until finely chopped. Add butter and olive oil to a large saute pan and set over medium heat. Add the shallot and mushroom mixture and saute for 8 to 10 minutes until most of the liquid has evaporated. Season with salt and pepper and set aside to cool.
• For the Beef:
• To prepare the beef: Tie the tenderloin in 4 places so it holds its cylindrical shape while cooking. Drizzle with olive oil, then season with salt and pepper and sear all over, including the ends, in a hot, heavy-based skillet lightly coated with olive oil - about 2 to 3 minutes. Meanwhile set out your prosciutto on a sheet of plastic wrap (plastic needs to be about a foot and a half in length so you can wrap and tie the roast up in it) on top of your cutting board. Shingle the prosciutto so it forms a rectangle that is big enough to encompass the entire filet of beef. Using a rubber spatula cover evenly with a thin layer of duxelles. Season the surface of the duxelles with salt and pepper and sprinkle with fresh thyme leaves. When the beef is seared, remove from heat, cut off twine and smear lightly all over with Dijon mustard. Allow to cool slightly, then roll up in the duxelles covered prosciutto using the plastic wrap to tie it up nice and tight. Tuck in the ends of the prosciutto as you roll to completely encompass the beef. Roll it up tightly in plastic wrap and twist the ends to seal it completely and hold it in a nice log shape. Set in the refrigerator for 30 minutes to ensure it maintains its shape.
• Preheat oven to 425 degrees F.
• On a lightly floured surface, roll the puff pastry out to about a 1/4-inch thickness. Depending on the size of your sheets you may have to overlap 2 sheets and press them together. Remove beef from refrigerator and cut off plastic. Set the beef in the center of the pastry and fold over the longer sides, brushing with egg wash to seal. Trim ends if necessary then brush with egg wash and fold over to completely seal the beef - saving ends to use as a decoration on top if desired. Top with coarse sea salt. Place the beef seam side down on a baking sheet.
• Brush the top of the pastry with egg wash then make a couple of slits in the top of the pastry using the tip of a paring knife ¿ this creates vents that will allow the steam to escape when cooking. Bake for 40 to 45 minutes until pastry is golden brown and beef registers 125 degrees F on an instant-read thermometer. Remove from oven and rest before cutting into thick slices. Garnish with minced chives, and serve with Green Peppercorn Sauce, Roasted Fingerling Potatoes with Fresh Herbs and Garlic, and Warm Wilted Winter Greens.
• Add olive oil to pan after removing beef. Add shallots, garlic, and thyme; saute for 1 to 2 minutes, then, off heat, add brandy and flambe using a long kitchen match. After flame dies down, return to the heat, add stock and reduce by about half. Strain out solids, then add 2 cups cream and mustard. Reduce by half again, then shut off heat and add green peppercorns.
• Preheat oven to 500 degrees F and place a baking sheet inside to heat.
• Add potatoes, rosemary, sage, thyme, and garlic to a medium bowl. Drizzle with olive oil, and season with salt and pepper. Remove sheet pan from oven, lightly coat with olive oil, and pour potatoes onto pan. Place potatoes in oven and reduce heat to 425 degrees F. Roast for 20 minutes, or until crispy on outside and tender on inside.
• Cook honey and balsamic together over medium-high heat in a large saute pan, about 5 minutes. Toast walnuts in a small skillet; set aside to cool.
• Pile greens on a platter. Stir mustard into balsamic-honey dressing, then whisk in about 1 cup extra-virgin olive oil; pour over greens. Season greens with salt and pepper and garnish with walnuts, pomegranate seeds, shavings of Parmesan, and shallot.

Steps:

• Working in two batches, pulse the mushrooms in a food processor until finely chopped, 10 to 15 pulses. Heat 3 tablespoons butter in a large skillet over medium-high heat. Add the shallots and thyme and cook until softened, 1 to 2 minutes. Stir in the mushrooms and cook, stirring often toward the end, until dry and starting to form small crumbles, 25 to 28 minutes.
• Remove the skillet from the heat and add the cognac. Carefully return the skillet to the heat (the cognac may ignite) and continue cooking until the mushroom mixture is dry and the alcohol cooks off, 2 to 3 minutes. Stir in the remaining 1 tablespoon butter and season with kosher salt and pepper. Remove from the heat and let cool completely.
• Meanwhile, season the beef all over with kosher salt and pepper. Heat the vegetable oil in a separate large skillet over medium-high heat. Add the beef and cook, turning, until browned on all sides (including the ends), about 8 minutes. Transfer the beef to a rack and let cool.
• Overlap 2 sheets of plastic wrap on a work surface to make a large rectangle (about 22 by 30 inches) with a short side in front of you. Arrange the prosciutto slices crosswise on the plastic wrap in overlapping rows to form a rectangle slightly longer than the beef and wide enough to completely wrap it with a slight overlap. (You might not use all of the prosciutto.) Spread the mushroom mixture over the prosciutto, pressing gently. Cut the ties off the beef and brush it all over with the mustard. Place the beef on top of the prosciutto-mushroom mixture, perpendicular to the prosciutto slices. Tightly roll the prosciutto-mushroom mixture around the beef, using the plastic wrap to help you roll. Twist and tie the ends of the plastic wrap to help the roast hold an even shape. Refrigerate at least 30 minutes.
• Roll the puff pastry into a 14-by-15-inch rectangle on a lightly floured surface; if using 2 smaller sheets of pastry, press the ends together before rolling out, then trim as needed. Brush the pastry all over with the beaten egg. Remove the plastic wrap from the beef and place the beef on the pastry. Carefully roll the pastry around the beef, overlapping the ends at the seam; trim off any excess pastry, if needed, then pinch the seams together. Turn seam-side down. Fold in the pastry on the two open ends, trimming off any excess. Refrigerate until the pastry is cold and firm, about 1 hour.
• Position a rack in the lower third of the oven; preheat to 425˚ F. Line a baking sheet with parchment paper or foil. Place the beef seam-side down on the baking sheet and brush all over with the beaten egg. Score lines in the pastry with the dull side of a paring knife (don't cut through the pastry) and sprinkle with flaky salt. Bake until the pastry is crisp and dark golden brown and a thermometer inserted into the center of the beef registers 110˚ F for rare to 120˚ F for medium rare, 40 to 50 minutes. Transfer to a rack set on a baking sheet and let rest 15 minutes before slicing. Sprinkle with more flaky salt and chives.

Steps:

• Using kitchen twine, tie the tenderloin into a 12-inch log, folding the thinner end onto itself. (Use your hands to squeeze the meat into a log. You can be aggressive here.)
• Place pancetta in a cold 12-inch skillet. Cook over medium heat, stirring occasionally, until pancetta starts to brown, 6 to 8 minutes.
• Add butter, raise heat to high, and stir in mushrooms and shallot. Cook until the liquid released by the mushrooms has cooked off, 4 to 7 minutes. Reduce heat to medium and continue to cook until mushrooms are browned, stirring frequently, another 18 to 23 minutes. (Take your time here, you want a deep golden color for the best flavor.) Scrape bottom of the skillet as necessary to prevent burning.
• If the pan looks dry, drizzle in a little olive oil, then stir in garlic and thyme leaves. Cook until fragrant, another 1 to 2 minutes. Stir in sherry, scraping up the browned bits on the bottom of the pan. Scrape mixture into a medium bowl to cool. (Do not add salt at this point.)
• In the same skillet, heat 2 tablespoons olive oil over medium-high. Season beef generously with salt and pepper, then sear on all sides until browned, 1 to 2 minutes per side. Transfer to a plate, and cool slightly. Remove any twine. Brush meat all over with mustard.
• On a clean work surface, overlap long sheets of plastic wrap (about 15-by-15 inches). Place prosciutto slices on top to make about a 14-by-7-inch rectangle, arranging them in an even layer and overlapping the pieces slightly. Spread cooled mushroom mixture on top.
• Place beef along one long end of the prosciutto slices, and roll prosciutto tightly around beef. Wrap tightly with plastic wrap, twisting both ends like a candy wrapper. Chill in the refrigerator for at least 30 minutes and up to overnight.
• Meanwhile, heat oven to 400 degrees, and line a rimmed baking sheet with parchment paper. In a small bowl, whisk together egg and 1 teaspoon water. Lay puff pastry out on the prepared baking sheet, lightly draping over edges. (The pastry needs to be at least 14-inches long and 13-inches wide to cover the beef; if not, roll it out as needed.)
• Carefully unwrap and place chilled log along the edge of one long side of puff pastry. Roll beef up tightly, then place it seam-side down on the baking sheet. Tuck puff pastry over the ends of the beef to cover them, pinching to seal and folding underneath. Brush top and sides of pastry with egg wash, and use a small sharp knife to cut a few slits into the top of the pastry.
• Bake until a thermometer inserted in the center reads 115 degrees for rare, 25 to 35 minutes. (This timing will yield rare pieces at the thicker end and medium done pieces at the thinner end of the loin.) Remove from oven and let rest for 10 minutes, then slice and serve while warm.
