K&W Cafeteria Baked Spaghetti

Preheat the oven to 350 degrees F.

Cook spaghetti according to package directions; drain and set aside.

Heat a large skillet over medium-high heat. Add the ground beef and onions and cook, stirring, until the beef is browned and broken up. Drain off any excess grease.

Add the salt, pepper, chili powder, 1/4 cup of the Cheddar cheese, the Worcestershire sauce, ketchup, and mustard to the ground beef. Mix well and simmer the beef mixture for 5 minutes.

Stir in the beef stock and the cooked pasta. Mix well.

Spoon the mixture into a 2-quart baking dish. Top the pasta with the remaining Cheddar cheese and the shredded Mozzarella.

Place the baking dish in the oven and bake at 350 degrees F for 20-30 minutes or until the cheese is browned and bubbly. Serve the K&W style baked spaghetti hot.
