Step-by-Step Instructions
1. Layer the Base
Place cubed butternut squash, chopped onion, and minced garlic into the slow cooker. Lay the chicken on top. Sprinkle with thyme, Italian seasoning, salt, and pepper. Pour in the chicken broth.
2. Slow Cook to Perfection
Cover and cook:
Low: 6–7 hours
High: 3–4 hours
The chicken should be tender and easily shreddable, and the squash should be very soft.
3. Shred and Blend
Remove the chicken and shred it with two forks. Using an immersion blender, blend the squash mixture directly in the slow cooker until smooth and creamy. (If you don’t have an immersion blender, carefully transfer the mixture to a blender in batches.)
Return the shredded chicken to the slow cooker and stir to combine.
4. Add Creaminess
Stir in the heavy cream and grated Parmesan cheese. Allow the mixture to cook for another 15–20 minutes to thicken slightly.
5. Cook the Rigatoni
While the sauce finishes, cook rigatoni according to package instructions until al dente. Drain well.
6. Combine and Finish
Add the cooked rigatoni to the slow cooker and gently fold it into the creamy butternut squash chicken sauce. If desired, stir in fresh spinach and let it wilt for a few minutes before serving.
Serving Suggestions
Serve hot with:
Extra Parmesan on top
Fresh chopped parsley
A pinch of red pepper flakes for gentle heat
A side of garlic bread or a crisp green salad
Tips for Success
Roast the squash first for deeper flavor. If you have extra time, roasting the squash at 400°F for 20 minutes before adding it enhances sweetness and caramelization.
Don’t overcook the pasta. Since it will sit in hot sauce briefly, slightly undercook it for best texture.
Adjust consistency. If the sauce is too thick, add a splash of broth. If too thin, let it cook uncovered for a few extra minutes.
Make it lighter. Substitute half-and-half or evaporated milk for heavy cream.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave, adding a small splash of broth or milk to loosen the sauce if needed.
This dish can also be frozen for up to 2 months, though the pasta texture may soften slightly upon reheating.
Final Thoughts
Slow Cooker Creamy Butternut Squash Chicken Rigatoni brings together convenience and comfort in one satisfying dish. The slow cooking process coaxes natural sweetness from the squash, creating a silky sauce that clings beautifully to rigatoni and tender shredded chicken. It’s cozy, nourishing, and guaranteed to become a seasonal favorite — especially on chilly evenings when only a warm bowl of creamy pasta will do.
