This creamy tomato rigatoni pasta is a rich, satisfying weeknight dinner made in minutes. Al dente rigatoni is tossed in a garlicky, buttery sauce made with tomato and cream, then finished with Parmesan for a family-friendly favorite.
Bring a large pot of salted water to boil. Add rigatoni and cook until al dente. Drain and set aside.
Melt butter in a skillet over medium heat. Add onion and cook until translucent, 3-4 minutes.
Add minced garlic and cook for another 1-2 minutes until fragrant.
Stir in salt, Italian seasoning, red pepper flakes, and black pepper. Cook for 30 seconds.
Sprinkle in flour. Stir for 1 minute to cook out raw flavor.
Gradually whisk in heavy cream. Bring to a simmer and stir until thickened, 4-5 minutes.
Add tomato sauce and stir to combine.
Return cooked rigatoni to skillet. Toss to coat well.
Simmer for 2-3 minutes more so flavors combine.
Serve hot topped with Parmesan cheese and optional fresh basil.
Notes
You can substitute half and half for heavy cream for a lighter version. Store leftovers in an airtight container for up to 3 days and reheat gently with a splash of cream or milk.
