For a comforting Southern beef macaroni skillet, start by browning one pound of ground beef in a large skillet over medium heat. Once the beef is cooked, drain any excess fat and add a chopped onion and a minced garlic clove, cooking until softened. Stir in a can of diced tomatoes, a cup of beef broth, and a tablespoon of Worcestershire sauce. Then, add two cups of elbow macaroni and bring the mixture to a boil. Reduce the heat, cover, and simmer for about 15 minutes until the pasta is tender. Finally, stir in a cup of shredded cheddar cheese until melted, and season with salt and pepper to taste. Serve hot for a delicious, one-pan meal that captures the essence of Southern comfort food.
