This creamy rigatoni with butternut squash and spicy sausage is the kind of dish that makes cold evenings feel warmer. The sweetness of the squash balances the heat of the sausage while creme fraiche and parmesan bring everything together in a silky finish. It is hearty enough to be the star of dinner yet simple enough for a weeknight.
I made this the first time on a snowy night and it quickly became one of my family’s most requested winter dinners.

Step-by-Step Instructions
- Cook the Squash:
- Heat olive oil in a large skillet over medium heat. Add diced butternut squash and cook until lightly browned and just starting to soften. Do not cook it completely at this stage as it will finish later.
- Add Onion and Sausage:
- Stir in the diced red onion and cook until tender and translucent. Add the crumbled sausage and cook thoroughly breaking it into small pieces with a spoon. The goal is a deep golden brown for maximum flavor.
- Add Greens and Garlic:
- Stir in chopped Swiss chard, minced garlic, and chili flakes. Cook until the chard wilts and the sausage mixture is well combined with the aromatics.
- Cook Pasta:
- Meanwhile bring a large pot of salted water to a boil. Cook rigatoni until al dente according to package directions. Reserve half a cup of cooking water then drain the pasta.
- Combine and Finish:
- Add rigatoni to the skillet with sausage and vegetables. Stir in creme fraiche and parmesan along with a splash of reserved pasta water. Toss until creamy and well coated. Taste and adjust seasoning with salt and pepper. Serve hot with extra parmesan on top.

My favorite part of this dish is how the squash melts slightly into the sauce. It reminds me of the meals I enjoyed at home growing up when hearty and creamy pasta dishes brought everyone to the table.
