Step 5: Blend the Butternut Squash Sauce

Using a spoon or potato masher, mash the softened butternut squash directly inside the slow cooker until it blends into the broth.

For an even smoother texture, you may use an immersion blender carefully inside the slow cooker.

The squash transforms into a naturally creamy sauce that becomes rich, silky, and flavorful.

Step 6: Cook the Rigatoni

While the sauce finishes developing, cook the rigatoni according to package instructions until al dente.

Drain the pasta but avoid overcooking it because it will continue absorbing sauce after being added to the slow cooker.

Rigatoni works especially well because the large pasta tubes hold the creamy sauce beautifully.

Step 7: Add Cream and Cheese

Stir the heavy cream and parmesan cheese into the slow cooker.

Mix slowly until the cheese melts completely into the sauce.

The sauce should become smooth, creamy, and rich without feeling too heavy.

Taste and adjust seasoning if necessary.

Step 8: Add Pasta and Spinach

Add the cooked rigatoni and fresh spinach to the slow cooker.

Gently stir until:

• The pasta becomes fully coated in sauce
• The spinach wilts
• All ingredients are evenly combined

Allow everything to sit for about 5 minutes so the flavors blend together.

Step 9: Serve and Garnish

Spoon the creamy rigatoni into serving bowls while hot.

Top with:

• Extra parmesan cheese
• Fresh parsley
• Cracked black pepper

The final dish should be creamy, hearty, comforting, and packed with rich autumn-inspired flavors.

Tips for the Best Creamy Rigatoni

Use Chicken Thighs for Extra Flavor

Chicken thighs remain especially juicy and tender during slow cooking.

Cut Squash into Small Pieces

Smaller cubes soften more evenly and blend more smoothly into the sauce.

Do Not Overcook the Pasta

Al dente pasta holds its texture better after mixing with the hot sauce.

Add Cheese Gradually

Slowly adding parmesan prevents clumping and helps create a silky texture.
