BEEF STROGANOFF

Steps:

• Bring a large pot of salted water to a boil.
• Cut the beef against the grain into 1/2-inch slices, pound lightly, then cut those slices into 1-inch-wide strips.
• Add the flour, paprika, 1 1/2 teaspoons salt and 1 1/2 teaspoons pepper to a large shallow bowl and toss to combine. Dredge the strips of meat in the flour mixture, shake them to remove excess flour, then transfer them to a rimmed baking sheet.
• Place a large skillet over high heat and swirl in the oil. When the oil begins to shimmer, sauté the beef slices, in two batches, until they are well browned on both sides but rare inside, 3 to 4 minutes per batch. Transfer the seared meat to the baking sheet. Turn the heat down slightly.
• Add 1 tablespoon of the butter to the pan. When it has melted and started to foam, add the mushrooms, toss to coat them with the fat, and season with salt and pepper. Cook, stirring frequently, until the mushrooms have released their moisture and are a deep, dark brown, 12 to 15 minutes. About halfway into the process, add the sliced shallots and 1 tablespoon butter and stir to combine.
• While the mushrooms cook, add the noodles to the boiling water, and cook until just done, about 10 minutes. Drain the noodles, and toss with the remaining 2 tablespoons butter. Set aside.
• When the mushrooms and shallots are soft and caramelized, deglaze the pan with the wine, scraping at all the stuck-on bits on the pan's surface. When the wine has reduced by about half, slowly stir in the cream, followed by the Worcestershire and mustard. Add the meat, along with any accumulated juices, and stir to combine. Cook, stirring occasionally, until the dish is hot and the beef is medium-rare, 2 to 3 minutes. Taste, and adjust the seasonings.
• Serve the noodles under or alongside the stroganoff; sprinkle stroganoff with parsley.
