Beef stroganoff is a classic and comforting dish that can be made with ground beef for a quick version. Brown the ground beef in a skillet, then add diced onions and mushrooms. Cook until the vegetables are softened, then stir in beef broth, sour cream, and Dijon mustard. Simmer the mixture for a few minutes to allow the flavors to meld together. Serve the beef stroganoff over cooked egg noodles or rice, and garnish with chopped parsley. This creamy and flavorful dish is perfect for a cozy dinner.
