Transform one pound of beef into a mouthwatering meal that tastes like cheeseburger pasta.
Heat a large skillet over medium-high heat. Add the lean ground beef and chopped onion. Cook, stirring and breaking up the meat, until the beef is browned and the onion is soft, about 7-10 minutes.
Stir in the tomato paste, garlic powder, and chili powder. Season with salt and pepper.
Pour in the beef broth and Worcestershire sauce; bring the mixture to a boil. Add the uncooked elbow macaroni and heavy cream, simmer.
