Creating Beef Lombardi Casserole is simple when you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Beef: In a large skillet over medium heat, brown the ground beef. Add the chopped onion and minced garlic, cooking until the onion is translucent.
3. Add Tomatoes: Stir in the crushed tomatoes, tomato paste, Italian seasoning, salt, and pepper. Simmer for 10 minutes to blend the flavors.
4. Combine Noodles and Cheese: In a large bowl, combine the cooked egg noodles, mozzarella cheese, cottage cheese, and half of the Parmesan cheese.
5. Mix Ingredients: Pour the beef mixture over the noodle and cheese mixture, stirring until well combined.
6. Transfer to Baking Dish: Spoon the combined ingredients into a greased baking dish, spreading it evenly.
7. Top with Remaining Cheese: Sprinkle the remaining Parmesan cheese over the top of the casserole.
8. Bake: Cover the dish with aluminum foil and bake for 30 minutes. Then remove the foil and bake for an additional 15 minutes, or until the cheese is bubbling and golden brown.
9. Let it Rest: Remove from the oven and let the casserole sit for about 10 minutes before serving.
10. Garnish: If desired, sprinkle fresh parsley on top for a pop of color.
