Add the ground beef to the skillet. Season with salt and pepper, then cook until browned and thoroughly cooked, breaking it up with a spatula as it cooks, about 6-8 minutes.
Reduce the heat to low and pour in the heavy cream. Stir well to combine with the beef and then gradually sprinkle in the grated Parmesan cheese, stirring until melted and the sauce is creamy.
Add the drained fettuccine to the skillet with the sauce. Toss gently to combine, ensuring the pasta is coated with that luscious Alfredo sauce. Adjust seasoning with more salt and pepper if desired.
Serve immediately, garnishing with fresh parsley for a pop of color and flavor. Enjoy!
