In a large pot or deep skillet, heat olive oil over medium heat. Add diced onion and ground beef. Cook until beef is browned and onions are softened. Drain any excess grease.
Stir in garlic, Worcestershire sauce, seasonings (onion powder, Meat Magic, Badia, salt, and pepper), tomato sauce, and Dijon mustard. Let everything simmer for a few minutes to blend the flavors.
Add in the beef broth and bring to a simmer. Stir in the dry pasta, cover, and cook until pasta is al dente, about 10–12 minutes, stirring occasionally.
Once pasta is tender, lower the heat and stir in the cream cheese until melted and smooth. Add the shredded cheddar cheese and mix until fully combined and creamy.
Serve hot. Top with green onions or relish if desired.
