Prepare the Base:

1. Cook the Beef: Heat a large pot or Dutch oven over medium heat. Add the ground beef and cook until browned, breaking it apart with a wooden spoon.
2. Add Onion and Garlic: Stir in the diced onion and garlic, cooking until the onion is translucent and fragrant, about 2-3 minutes.

Build the Sauce:

3. Incorporate Seasonings: Sprinkle in the dried basil, oregano, and red pepper flakes (if using). Stir to combine.
4. Add Tomatoes and Broth: Pour in the crushed tomatoes and beef broth, stirring well to create the sauce base.

Cook the Pasta:

5. Add the Pasta: Stir in the uncooked pasta, ensuring it is fully submerged in the liquid.
6. Simmer: Bring the mixture to a boil, then reduce the heat to medium-low. Cover and simmer for 12-15 minutes, stirring occasionally, until the pasta is al dente and has absorbed most of the liquid.

Finish the Dish:

7. Add Cream and Cheese: Stir in the heavy cream and mozzarella cheese until melted and combined, creating a creamy, cohesive sauce.
8. Season to Taste: Adjust with salt and pepper as needed.

Serve:

9. Garnish: Sprinkle with fresh parsley or basil, if desired, and serve hot.
