Bring a large pot of salted water to a boil for the pasta. In a separate large pot or deep skillet, cook the ground beef over medium-high heat, breaking it up with a spoon, until browned and no longer pink. Drain off excess fat.



Reduce the heat to medium. Add the black pepper, crushed red pepper, minced garlic, diced shallots, and spicy brown mustard to the beef. Cook for 3 to 5 minutes, stirring often, until the shallots soften and the garlic is fragrant.



Pour in the beef broth and stir well, scraping up any browned bits from the bottom of the pot. Let the mixture simmer for 4 to 5 minutes so the flavors blend and the liquid reduces slightly.



Stir in the heavy cream, then lower the heat. Simmer gently for 3 to 5 minutes, stirring occasionally, until the sauce is smooth and lightly thickened. Do not let the cream boil hard.



Meanwhile, cook the pasta according to the package directions until al dente. Drain well, then add the pasta to the creamy beef sauce. Toss gently until the pasta is evenly coated.



Remove the pot from the heat and let the pasta stand for 1 to 2 minutes so the sauce can cling to the noodles. Serve warm with Parmesan cheese sprinkled over the top.
