A Little Background

My first run at this sauce was a messy peel-and-chop session on a rainy Saturday. By the third attempt, I’d learned that a Y-peeler yields thinner, more uniform butternut slices, speeding roast time to a perfect 30 minutes. This sauce draws on Italian cucina povera, turning simple squash into a rich, comforting sauce that sings of fall.

Key Ingredients for Butternut Squash Pasta Sauce

Butternut squash (1 kg): Provides creamy base; sub with pumpkin if needed
Olive oil (3 tbsp): Use extra-virgin for fruitier notes
Onion (1 large): Finely chopped to melt into sauce
Garlic (2 cloves): Crushed for a gentle pungency
Vegetable stock (250 ml): Adds depth; adjust thickness by adding pasta water

How to Make Butternut Squash Pasta Sauce

Preheat the oven to 200°C (180°C fan). Peel, seed, and cube the squash into 2 cm pieces. Toss with 1 tbsp olive oil, season with salt and pepper, and spread on a baking tray. Roast for 30 minutes until edges turn golden and tender.
Meanwhile, heat remaining oil in a skillet over medium heat. Add chopped onion and cook for 5 minutes until translucent, then stir in garlic and sauté for 1 more minute until it releases a nutty aroma.
Transfer the roasted squash, onions, and garlic into a blender. Pour in the vegetable stock and add ground nutmeg. Blend on high for 1–2 minutes until the mixture is silky smooth and glossy.
Pour the puree back into the skillet. Bring to a gentle simmer and cook for 10 minutes, stirring occasionally. Season to taste. In the meantime, cook 350 g pasta in salted boiling water, drain, reserving 60 ml pasta water, and toss with the sauce, adding water to reach desired consistency.

Pro Tips & Troubleshooting

On my cooking test, stirring every 5 minutes prevented the sauce from sticking and encouraged even color.
If the sauce seems grainy, add more warm pasta water a splash at a time to smooth it out.
Swirl in a teaspoon of fresh sage or thyme leaves in autumn for a woodland aroma.
To halve the batch, reduce stock to 125 ml and roast 500 g squash for 20 minutes.

Storage & Make-Ahead Guide

Let the sauce cool to room temperature and refrigerate in a sealed container for up to 5 days. For longer storage, freeze portions in airtight bags for up to 3 months—test showed freezing in ½-cup scoops works best. Reheat gently on low, stirring until piping hot. Discard any sauce left at room temperature beyond 2 hours for safety.

Serving Suggestions

Drizzle extra-virgin olive oil and sprinkle grated Parmesan or toasted pine nuts over a steaming bowl of fusilli. Add crisp pancetta or roasted mushrooms on top for texture contrast, or swirl into baked penne for a golden, bubbling crust.
