# Preparation steps:
01 - Bring a large pot of salted water to a boil. Add rigatoni and cook according to package directions until al dente. Reserve ½ cup pasta water, then drain the pasta.
02 - While pasta cooks, heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3 to 4 minutes until soft and translucent.
03 - Stir in garlic and red pepper flakes. Cook for 1 minute until fragrant.
04 - Add tomato paste and cook, stirring constantly, for 2 minutes to deepen flavor.
05 - Pour in crushed tomatoes. Simmer for 8 to 10 minutes, stirring occasionally, until sauce thickens.
06 - Reduce heat to low. Stir in heavy cream and Parmesan cheese. Season with salt and pepper. Simmer gently for 2 to 3 minutes until creamy and smooth.
07 - Add drained rigatoni to sauce and toss to coat evenly. If sauce appears too thick, add reserved pasta water gradually until desired consistency is achieved.
08 - Transfer to serving plates immediately. Garnish with fresh basil and extra Parmesan cheese.
