Cook the egg noodles according to package directions for al dente and drain well.
Meanwhile, in a large skillet, heat the oil over MEDIUM-HIGH heat. Brown the meatballs, then transfer to a plate and set aside.
Melt the butter in the empty skillet over MEDIUM heat and add the mushrooms. Cook, stirring occasionally until they are tender and nicely browned, about 5 to 6 minutes, then transfer them to the plate with the meatballs.
Return the empty skillet to MEDIUM heat, add the wine and bring it to a low boil, stirring to deglaze the pan. Cook at a low boil for about 2 minutes to reduce just slightly.
Add the beef broth and whisk in the Dijon and worcestershire sauce, Italian seasoning, paprika, garlic powder, and salt and pepper, to taste. Increase the heat as needed to bring the liquid to a boil and cook for about 6 to 7 minutes, to reduce just slightly and intensify the flavors.
Reduce heat to MEDIUM-LOW and add the cream, browned meatballs, mushrooms, and the cooked and drained noodles. Bring to a simmer and allow the sauce to cook for several minutes, just until slightly thickened. Reduce the heat to LOW and stir in the sour cream and stir until everything is well coated in sauce. Stir in the parsley and serve immediately.
