Step 1

Preheat oven to 375 degrees.

Step 2

Start browning your ground beef in a large pot over medium heat.  After 2-3 minutes add the onion and continue cooking until the beef is browned and the onions are soft.  Add the garlic, cayenne, and crushed red pepper.  Cook for 1 minute stirring continuously.

Step 3

Add the ketchup, tomato paste, Worcestershire sauce, mustard, and beef broth.  Bring it to a low boil.  Add the pasta and cover the pot cooking the pasta until it is tender.  Remove from the heat and stir in half of the cheese.

Step 4

Meanwhile in a small bowl whisk together the olive oil, marjoram, parsley, garlic powder, onion powder, salt, and pepper.  Toss in the bun cubes and stir gently to coat.  Place the croutons on a parchment covered baking sheet.  Bake for 15-20 minutes or until crispy.

Step 5

Spoon the pasta into a large deep 9x13 baking dish sprayed with nonstick cooking spray, top with the remaining cheese, and sprinkle with the croutons.  Bake for 15-20 minutes or until the cheese is melted and the casserole is heated through.
