Ingredients

(Kept exactly as provided)

The Golden Sauce Base:

• 1½ cups (360g) canned butternut squash puree (not pumpkin pie mix—check label for “100% squash”)

• 1½ cups (360ml) low-sodium chicken broth, warmed 1 minute

• 1 cup (240ml) heavy cream, 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—dried intensifies during cooking)

• ¼ tsp freshly grated nutmeg (not powdered—grate whole for floral warmth)

• 1 tsp garlic powder

• 1 tsp onion powder

• 1¼ tsp kosher salt (plus more to taste)

• ½ tsp freshly cracked black pepper

The Foundation:

• 1 lb (450g) boneless, skinless chicken breasts (or thighs for extra juiciness)

• 12 oz (340g) dry rigatoni (ridged tubes hold sauce better than smooth pasta)

• 1 small yellow onion, thinly sliced

• 2 garlic cloves, microplaned or finely minced

For Finishing:

• ½ cup warm water or broth (only if needed for sauce consistency)

• Fresh parsley or sage, finely chopped

• Extra Parmigiano-Reggiano

Instructions / Method

(Instructions kept exactly as provided – formatting improved)

1. Whisk the golden sauce

In a large liquid measuring cup or bowl, vigorously whisk warmed broth, squash puree, cream, olive oil, Parmesan, sage, nutmeg, garlic powder, onion powder, salt, and pepper until completely smooth (no streaks). Critical: Warm broth prevents temperature shock in slow cooker.

2. Layer with intention

Lightly grease 6-quart slow cooker insert. Place chicken in single layer on bottom. Scatter onion and garlic over chicken. Do not stir. Arrange dry rigatoni in even layer on top—do not press down.

3. Pour with purpose

Slowly drizzle sauce over pasta, tilting slow cooker gently to help liquid seep beneath pasta. Gently press only exposed pasta tips below liquid surface with spoon. If liquid doesn’t cover ¾ of pasta: add up to ½ cup warm water. Do not stir—this prevents pasta from sinking and becoming gummy.

4. Cook without peeking

Cover and cook:

→ LOW 4 hours (ideal for tender pasta and shreddable chicken)

→ HIGH 2¼ hours (if short on time—check at 2 hours)

Do not lift lid before 3 hours (LOW) or 1.5 hours (HIGH)—steam is essential for cooking pasta.

5. Unite gently

Chicken is done at 165°F internally; pasta should be tender but firm. Shred chicken directly in pot with two forks. Gently fold sauce, chicken, and pasta together 2–3 times—do not overmix. If sauce is too thick, stir in warm water/broth 2 tbsp at a time. Taste; adjust salt/pepper.

6. Rest and serve

Cover and let rest 5 minutes so the sauce thickens. Garnish with parsley, extra Parmigiano, and black pepper. Serve immediately.
