How to Make It

1. Prepare the Creamy Sauce
In a large bowl or measuring cup, whisk together the warm broth, butternut squash purée, cream, olive oil, Parmesan, sage, nutmeg, garlic powder, onion powder, salt, and pepper until completely smooth.

2. Layer the Slow Cooker
Lightly grease a 6-quart slow cooker. Place chicken in a single layer at the bottom, then add sliced onion and minced garlic on top. Do not stir.

3. Add the Pasta
Spread the dry rigatoni evenly over the chicken and vegetables. Avoid pressing it down.

4. Pour the Sauce
Slowly pour the sauce mixture over everything, allowing it to seep through. Gently press any exposed pasta under the liquid. If needed, add a small amount of warm broth so most of the pasta is covered.

5. Slow Cook
Cover and cook:

  • LOW for 4 hours, or
  • HIGH for about 2–2½ hours

Avoid lifting the lid too early, as the steam is essential for cooking the pasta properly.

6. Finish and Combine
Once the chicken is cooked through and pasta is tender, shred the chicken directly in the slow cooker. Gently stir everything together until evenly coated. Add a splash of warm broth if the sauce is too thick.

7. Rest and Serve
Let the dish sit for 5 minutes before serving. Garnish with fresh herbs and extra Parmesan.
