Creating Creamy Parmesan Beef Rigatoni is straightforward. Follow these simple steps:

1. Cook the Pasta: Begin by boiling a large pot of salted water. Add rigatoni and cook according to package instructions until al dente. Drain and set aside.

2. Brown the Beef: In a large skillet over medium heat, add olive oil. Once hot, add diced onions and minced garlic. Sauté until translucent.

3. Season the Beef: Increase the heat to medium-high and add in the ground beef. Cook, breaking it apart with a spatula, until browned. Drain excess fat if necessary.

4. Add Cream: Pour in the heavy cream and stir. Allow it to simmer, making sure to scrape any bits off the bottom of the skillet to incorporate all flavors.

5. Melt the Cheese: Gradually add the grated Parmesan cheese. Stir continuously until the cheese melts and the sauce thickens slightly.

6. Combine with Pasta: Add the cooked rigatoni to the skillet. Toss gently to coat the pasta evenly with the creamy sauce.

7. Add Seasoning: Sprinkle in Italian seasoning, salt, and pepper to taste. Mix until fully combined.

8. Add Mozzarella: Stir in the shredded mozzarella cheese until melted and well distributed throughout the dish.

9. Garnish and Serve: Remove from heat and transfer to a serving platter. Top with chopped parsley for added freshness.

These steps will guide you to create a dish that is not only visually appealing but also delicious beyond measure!
