# How To Make It:
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 3-4 minutes until soft and translucent.
03 - Stir in garlic and red pepper flakes, cooking for 1 minute until fragrant. Add tomato paste and cook, stirring, for 2 minutes to caramelize slightly.
04 - Pour in crushed tomatoes and simmer for 8-10 minutes, stirring occasionally, until the sauce thickens.
05 - Reduce heat to low. Stir in heavy cream and Parmesan cheese. Season with salt and pepper. Simmer gently for 2-3 minutes until creamy.
06 - Add drained rigatoni to the sauce and toss to coat. If sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached. Serve immediately garnished with fresh basil and extra Parmesan.
