Brown the Beef:

• In a large skillet or Dutch oven, heat a tablespoon of oil over medium-high heat. Add the ground beef and cook, breaking it apart with a spoon, until browned and fully cooked (about 5-7 minutes). Drain any excess grease if needed.

Sauté the Onion and Garlic:

• Add the diced onion to the skillet and cook for 2-3 minutes until softened. Add the minced garlic and cook for an additional 30 seconds until fragrant.

Make the Sauce:

• Stir in the uncooked pasta, beef broth, and milk. Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for 12-15 minutes, stirring occasionally, until the pasta is tender and most of the liquid is absorbed.

Finish the Dish:

• Stir in the shredded cheddar cheese, ketchup, and mustard (if using). Continue stirring until the cheese melts and the sauce becomes creamy. Season with salt and pepper to taste.

Serve:

• Once well combined, serve immediately. Garnish with fresh chopped parsley if desired.
