- 2 cups low-sodium vegetable broth (chicken broth adds extra richness)
- 1/2 cup heavy cream (coconut cream for dairy-free option)

- 1 teaspoon fresh sage, chopped (or 1/2 teaspoon dried sage)
- 1/2 teaspoon ground nutmeg

Step-by-Step Instructions
Step 1: Prepare Your Butternut Squash Foundation
Heat olive oil in a large, heavy-bottomed pot over medium heat. Add the cubed butternut squash and cook for 8-10 minutes, stirring occasionally until edges begin to caramelize. This crucial step develops the deep, nutty flavors that make restaurant-quality butternut squash pasta sauce so memorable. The squash should develop golden-brown edges while remaining firm in the center.
Step 2: Build Your Aromatic Base
Add diced onion to the pot with the squash, cooking for 5 minutes until translucent and fragrant. Stir in minced garlic and cook for an additional 30 seconds until aromatic. This foundation creates the flavor complexity that distinguishes homemade sauce from store-bought alternatives. Season with salt and pepper to enhance natural sweetness.
Step 3: Create the Simmering Magic
Pour vegetable broth over the squash mixture, ensuring liquid covers the vegetables by about 1 inch. Add sage and nutmeg, then bring to a gentle boil. Reduce heat to medium-low and simmer covered for 20-25 minutes, until squash pieces pierce easily with a fork. The gentle simmer prevents bitter flavors while concentrating the natural sweetness.
Step 4: Transform to Silky Perfection
Using an immersion blender, carefully puree the mixture until completely smooth and velvety. Alternatively, transfer in batches to a regular blender (allow cooling first for safety). The sauce should coat the back of a spoon without being too thick. This technique creates the signature creamy texture that makes butternut squash pasta sauce so luxurious.
Step 5: Final Flavor Enhancement
Stir in heavy cream and any optional ingredients like Parmesan cheese or maple syrup. Simmer for 3-5 minutes to meld flavors. Taste and adjust seasoning with salt, pepper, and additional nutmeg as needed. The sauce should be rich, creamy, and balanced between sweet and savory notes.

Blending hot liquids unsafely: Always allow slight cooling or use an immersion blender to prevent dangerous splattering.
Wrong consistency: The sauce should coat pasta without being too thick or watery. Adjust with additional broth or cream as needed.
