Equipment
Method
Cook pasta
- Bring a large pot of salted water to a boil, then cook rigatoni or penne until al dente. Before draining, reserve 1/2 cup pasta cooking water.
Brown sausage and build the sauce base
- Brown the Italian sausage in a large cast iron skillet over medium-high heat until cooked through, then drain excess fat and set the sausage aside.
- Sauté the onion in the same skillet for 4 minutes until softened, stirring as needed.
- Add the garlic, Italian seasoning, and cook for 2 minutes until fragrant.
- Stir in butternut squash puree and heavy cream, then add nutmeg and red pepper flakes.
Simmer and combine
- Simmer the sauce for 5 minutes, then add parmesan and stir until completely smooth and melted.
- Toss the cooked pasta with the sauce and drizzle in reserved pasta cooking water until glossy and evenly coated.
- Add the baby spinach and toss until wilted, about 1 to 2 minutes.
- Return the sausage to the pan, season with salt and pepper to taste, and toss to heat through.
Notes
For the silkiest texture, simmer the squash-cream sauce gently and add parmesan off any harsh boiling to prevent graininess. Store leftovers in the fridge up to 3 days; reheat with a splash of milk or water to loosen the sauce. Freeze is not recommended because cream sauce can separate after thawing. If you want a lower-fat option, swap heavy cream for half-and-half (the sauce will be a bit lighter).
