Method
Cook the pasta
- Bring the water and kosher salt to a boil in a 6-quart pot.
- Add the rigatoni and cook according to package directions until al dente.
- Reserve 1 cup of pasta water before draining the rigatoni.
Make the sauce
- While the pasta cooks, heat the olive oil in a 12-inch skillet over medium-high heat.
- Add the sausage and cook for 7 to 9 minutes, breaking it into small pieces, until browned and cooked to 160°F.
- Add the onion and cook for 4 to 5 minutes, stirring, until softened.
- Add the garlic and red pepper flakes and cook for 30 seconds.
- Stir in the tomato paste and cook for 1 to 2 minutes.
- Pour in the vodka and simmer for 2 to 3 minutes, until reduced by about half.
- Add the crushed tomatoes and bring the sauce to a simmer.
- Cook for 10 to 15 minutes, stirring occasionally.
- Reduce the heat to low and stir in the heavy cream and Parmesan.
- Cook for 1 to 2 minutes, until the cheese melts.
Combine and serve
- Add the drained rigatoni to the skillet and toss until coated, adding reserved pasta water a few tablespoons at a time as needed to loosen the sauce.
Notes
Reserve pasta water before draining; add it a few tablespoons at a time to loosen the sauce without making it watery. Refrigerate leftovers for 3 to 4 days, or freeze them; the cream sauce may separate slightly when reheated. For a gluten-free option, use gluten-free rigatoni.
