Ingredients
-
1.5 pounds Boneless, skinless chicken breasts (Cubed)
-
4 cups Butternut squash (Peeled and diced into 1-inch cubes)
-
2 cups Chicken broth
-
1/2 medium Yellow onion (Finely diced)
-
2 cloves Fresh garlic (Minced)
-
1 teaspoon Dried sage
-
1/2 teaspoon Freshly grated nutmeg
-
1/2 cup Heavy cream (Or full-fat coconut milk)
-
1/2 cup Grated Parmesan cheese
-
1 pound Rigatoni pasta (Cooked al dente)
-
Salt and black pepper (To taste)
Instructions
-
Place the cubed chicken, butternut squash, diced onion, and minced garlic into a 6-quart slow cooker.
-
Pour the chicken broth over the ingredients and stir in the sage, nutmeg, salt, and pepper.
-
Cover and cook on Low for 5 to 6 hours (or on High for 3 hours) until the squash is very tender and the chicken is cooked through.
-
Using a slotted spoon, temporarily remove the chicken pieces and set them aside on a plate.
-
Use an immersion blender directly in the slow cooker to blend the squash and broth into a smooth, creamy sauce. (Alternatively, carefully transfer to a standard blender).
-
Stir the heavy cream and Parmesan cheese into the squash puree until the sauce is rich and consistent.
-
Add the cooked chicken back into the sauce, along with the cooked rigatoni pasta.
-
Toss everything together until the pasta is fully coated in the golden sauce.
-
Cover and heat on Low for an additional 10 to 15 minutes to allow the flavors to meld.
-
Serve hot, garnished with a sprinkle of extra Parmesan or a few fresh sage leaves.
Why This Recipe Works
-
The slow-cooking process allows the butternut squash to fully soften, making it easy to create a cream-based sauce without needing a traditional flour-and-butter roux.
-
Nutmeg and sage are the classic “soulmates” of squash, highlighting its natural sweetness while adding a savory, herbal depth to the chicken.
-
Rigatoni is the ideal pasta choice for this dish because its large ridges and hollow center are designed to hold onto thick, pureed sauces.
-
Using chicken breast ensures the protein stays lean, while the pureed squash provides all the richness you’d expect from a heavy pasta dish.
Tips for Best Results
Buy pre-cut butternut squash if you are short on time. Peeling and cubing a whole squash can be the most labor-intensive part of the recipe; most grocery stores offer fresh, pre-cubed squash in the produce section.
Don’t overcook the pasta. Since the rigatoni will sit in the warm sauce for a few minutes at the end, cook it for 1–2 minutes less than the package directions. This prevents the noodles from becoming mushy.
If the sauce is too thick after blending, add a splash more of chicken broth or pasta water until you reach your desired “silky” consistency.
Variations & Substitutions
For a “Spiced” version, add a pinch of red pepper flakes or a half-teaspoon of smoked paprika to the slow cooker to contrast the sweetness of the squash.
If you want to make this Vegetarian, simply omit the chicken and use vegetable broth. You can add roasted chickpeas or sautéed kale at the end for extra texture.
To make this Dairy-Free, use full-fat canned coconut milk instead of heavy cream and substitute the Parmesan for nutritional yeast or a dairy-free cheese alternative.
Frequently Asked Questions
How should I store and reheat leftovers?
Store in an airtight container in the fridge for up to four days. When reheating, add a tiny splash of water or milk to the pasta, as the squash sauce tends to thicken significantly once cooled.
Can I use frozen butternut squash?
Yes, frozen squash works perfectly in this recipe. Since it is usually pre-blanched, it may even cook a little faster than fresh squash.
Can I cook the pasta in the slow cooker?
While possible, it is not recommended for this specific sauce. Cooking pasta in the slow cooker often leads to an uneven texture; cooking it separately on the stove ensures it stays perfectly al dente.
Why is my sauce watery?
This can happen if too much broth was used or the squash had a high water content. To fix this, let the sauce simmer uncovered for 20 minutes before adding the pasta to allow some moisture to evaporate.
There is a simple, rustic elegance in a bowl of golden pasta. Slow Cooker Creamy Butternut Squash Chicken Rigatoni is a reminder that healthy ingredients can be transformed into something that feels like a true luxury. We hope this velvety, comforting meal brings a sense of warmth to your kitchen this season.
