Heat a large skillet over medium heat. Add ground beef, diced onion, and minced garlic. Cook until meat is browned, draining excess fat if necessary.

Stir in taco seasoning, macaroni, beef broth, and diced tomatoes. Bring the mixture to a boil.

Once boiling, reduce the heat, cover, and let it simmer for about 10-12 minutes until the macaroni is cooked and most of the liquid has been absorbed.

Remove from heat and mix in the shredded cheddar cheese until it melts into the creamy sauce.

Season with salt and pepper to taste. Plate it up and serve warm with optional toppings.
