Ingredients

(Kept exactly as provided)

The Golden Sauce Base

• 1½ cups (360g) canned butternut squash puree (100% squash, not pie filling)
• 1½ cups (360ml) low-sodium chicken broth, gently warmed
• 1 cup (240ml) heavy cream, at room temperature
• ½ cup (50g) finely grated Parmigiano-Reggiano, plus extra for serving
• 2 tbsp extra-virgin olive oil
• 2 tsp dried rubbed sage (or 1 tbsp fresh sage)
• ¼ tsp freshly grated nutmeg
• 1 tsp garlic powder
• 1 tsp onion powder
• 1¼ tsp kosher salt, or to taste
• ½ tsp freshly ground black pepper

The Foundation

• 1 lb (450g) boneless, skinless chicken breasts (or thighs for extra juiciness)
• 12 oz (340g) dry rigatoni
• 1 small yellow onion, thinly sliced
• 2 garlic cloves, finely minced

For Finishing

• ½ cup warm water or broth (only if needed to adjust consistency)
• Fresh parsley or sage, finely chopped
• Extra Parmigiano-Reggiano for serving

Instructions / Method

1. Prepare the creamy sauce

In a large bowl or measuring jug, whisk together warmed broth, butternut squash puree, cream, olive oil, Parmesan, sage, nutmeg, garlic powder, onion powder, salt, and pepper until completely smooth and creamy. Warming the broth helps everything blend more evenly.

2. Build the layers

Lightly grease a 6-quart slow cooker. Add chicken in an even layer at the bottom. Top with sliced onion and garlic. Next, spread the dry rigatoni evenly over the top—do not press or stir.

3. Add the sauce

Slowly pour the sauce over everything, gently tilting the slow cooker so it spreads evenly. Lightly press any exposed pasta under the liquid. If needed, add up to ½ cup warm water or broth. Do not stir.

4. Slow cook to perfection

Cover and cook:

• LOW: 4 hours (best texture and flavor)
• HIGH: 2¼ hours (faster option)

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

5. Combine and finish

Once cooked, check that chicken reaches 165°F and pasta is tender. Shred the chicken directly in the pot using two forks. Gently fold everything together until combined. If the sauce is too thick, add a small splash of warm broth.

6. Rest and serve

Let the dish sit for 5 minutes to thicken. Garnish with fresh herbs, extra Parmesan, and black pepper before serving warm.
