HOW TO MAKE BUTTERNUT SQUASH PASTA SAUCE

Bringing these ingredients to life is easier than you might think. Follow these steps to transform simple produce into a dreamy, restaurant-quality sauce that’s bound to wow your family and friends.

1. Preheat your oven to 400°F (200°C). Arrange the diced squash on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast for 25–30 minutes until tender and slightly caramelized, stirring once halfway through for even browning.

2. In a large skillet over medium heat, heat the remaining olive oil. Add the chopped onion and sauté for about 5 minutes until it turns translucent and soft, stirring occasionally to avoid browning too quickly.

3. Add the minced garlic to the skillet and cook for 1–2 minutes, just until fragrant, being careful not to let it burn.

4. Stir in the roasted butternut squash and pour in the vegetable broth. Let it simmer gently for about 5 minutes so the flavors meld and the squash absorbs some of the savory broth notes.

5. Remove the skillet from the heat. Using a blender or immersion blender, puree the mixture until completely smooth and creamy, scraping down the sides as needed.

6. Return the pureed sauce to the skillet and stir in the heavy cream and ground nutmeg. Cook over low heat for another 3–5 minutes until the sauce thickens slightly and becomes luxuriously velvety.

7. Season with additional salt and pepper to taste. Fold in the grated Parmesan cheese, stirring until it melts and incorporates fully into the sauce.

8. Serve the warm sauce over your favorite cooked pasta, tossing gently to coat every strand. Garnish with fresh basil leaves if desired, and dig in!
