Making the Cheesy Beef and Pasta Casserole is simple when you follow these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Pasta: In a large pot, cook the pasta according to package instructions until al dente. Drain and set aside.
3. Brown Beef: In a large skillet, heat olive oil over medium heat. Add the diced onion and minced garlic, cooking until softened.
4. Add Ground Beef: Add the ground beef to the skillet, breaking it up with a spoon. Cook until browned and no longer pink.
5. Mix in Sauces: Stir in the tomato sauce, diced tomatoes, beef broth, Italian seasoning, salt, and black pepper. Let simmer for about 5 minutes.
6. Combine Pasta: Add the cooked pasta to the beef mixture, stirring to combine thoroughly.
7. Layer with Cheese: In a greased 9×13 inch baking dish, spread half of the pasta and beef mixture. Sprinkle half of the shredded cheese on top. Repeat with the remaining mixture and cheese.
8. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
9. Cool: Once baked, let the casserole cool for a few minutes before serving.
10. Garnish: If desired, sprinkle fresh parsley on top for a pop of color.
