# Step-by-Step Guide:
01 - Bring a large pot of salted water to a boil. Add rigatoni and cook until al dente according to package instructions. Reserve ½ cup pasta water, then drain the rigatoni.
02 - 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 minced garlic and crushed red pepper flakes. Cook for 1 minute until fragrant.
04 - Add tomato paste and cook, stirring constantly, for 2 minutes to caramelize slightly.
05 - Pour in crushed tomatoes. Simmer for 8 to 10 minutes, stirring occasionally, until the sauce thickens.
06 - Reduce heat to low. Stir in heavy cream and Parmesan cheese. Season with salt and black pepper. Let the sauce simmer gently for 2 to 3 minutes until creamy.
07 - Add drained rigatoni to the sauce and toss to coat evenly. If sauce is too thick, add reserved pasta water gradually to reach the desired consistency.
08 - Serve immediately, topped with chopped fresh basil and extra Parmesan cheese.
