A fun and easy Cheeseburger Casserole with ground beef, onion, garlic and pasta in a cheesy sauce topped with more cheese and fresh homemade bun croutons. The end result is so tasty that you will want to make this over and over again.
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.
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.
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.
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.
Notes
If you use a Dutch oven for the pasta portion of the recipe, you do not need to transfer it to a casserole dish because they are oven safe.
The croutons can be made up to a day in advance and stored in an airtight container.
Cheddar, Pepper Jack, Colby Jack, White Cheddar, or Gouda can be substituted for Colby.
Customize with toppings like dill pickles, diced tomatoes, and shredded lettuce.
Pasta substitutions include elbow macaroni, penne, rotini, ziti, rigatoni, and medium-shell pasta.
Add a little ground sausage to the hamburger mix for an over-the-top taste sensation.
Store leftovers in an airtight container in the fridge for up to 3 days or freeze for up to 3 months.
