By September 5, 20267 min read

You know that moment when the first crisp autumn breeze hits your face, and you suddenly crave something warm, comforting, and a little bit decadent? That's exactly how this fall pasta came to be. Last weekend, I found myself staring at a lonely butternut squash in my kitchen, dreaming of a dish that would wrap me in a cozy blanket of flavor.

This isn't your average pasta. We roast the squash until it's caramelized and sweet, then blend it into a silky, golden sauce that clings to every noodle. Add crispy sage leaves, toasted walnuts, and a shower of parmesan, and you've got a bowl of pure autumn happiness. It's the kind of meal that makes you want to light a candle and pour a glass of wine, even on a Tuesday.

And the best part? It's surprisingly simple to pull together. You can even roast the squash ahead of time. So grab your favorite pot, and let's make some magic happen.

About the Ingredients

1 medium butternut squash (about 2 lbs / 900g), peeled, seeded, and cut into 1-inch cubes

Look for a squash with a long neck for easier peeling. You can substitute 3 cups of pre-cut butternut squash to save time.

3 tablespoons olive oil, divided

Use a good extra-virgin olive oil for roasting and sautéing. Avocado oil works too.

1 teaspoon salt, plus more for pasta water

Kosher salt is best for seasoning. Adjust to taste.

1/2 teaspoon black pepper, freshly ground

Freshly ground pepper adds a nice kick. Pre-ground works in a pinch.

12 oz (340g) fettuccine or your favorite long pasta

I love fettuccine, but any shape works. Gluten-free pasta is fine too.

1 cup (240ml) heavy cream

For a lighter option, use half-and-half or whole milk mixed with a tablespoon of flour.

1/2 cup (50g) grated Parmesan cheese, plus more for serving

Freshly grated parmesan melts best. Pecorino Romano adds a sharper flavor.

1/4 cup (30g) walnuts, toasted and roughly chopped

Pine nuts or pecans are lovely substitutes. Toast them in a dry pan until fragrant.

8 fresh sage leaves

If you don't have fresh sage, use 1 teaspoon dried. But fresh is truly best.

Pinch of nutmeg (optional)

A little nutmeg enhances the squash's sweetness. Skip if you don't have it.

Tips & Tricks

  • To peel butternut squash easily, microwave it for 2-3 minutes to soften the skin, then use a vegetable peeler.
  • Don't overcrowd the baking sheet when roasting; otherwise, the squash steams instead of caramelizing.
  • Reserve a cup of pasta water before draining – the starchy water is gold for adjusting sauce consistency.

Pro Tips

1

Roast for deeper flavor: Toss the squash with olive oil, salt, and pepper, and roast at 425°F (220°C) until fork-tender and caramelized, about 25-30 minutes.
2

Sage crispiness: Fry the sage leaves in a little butter or oil until they turn dark green and crispy – they'll shatter like chips.
3

Sauce smoothness: Blend the roasted squash with a splash of cream until completely smooth for a velvety sauce.
4

Pasta water is your friend: Add a splash of reserved pasta water to the sauce to loosen it and help it cling to the noodles.

Step-by-Step Instructions

1. Roast the Squash

Preheat your oven to 425°F (220°C). On a baking sheet, toss the cubed squash with 2 tablespoons of olive oil, salt, and pepper. Spread in a single layer and roast for 25-30 minutes, until golden brown and easily pierced with a fork. Set aside to cool slightly.

2. Cook the Pasta

Bring a large pot of salted water to a boil. Cook the fettuccine according to package directions until al dente. Reserve 1 cup of pasta water, then drain.

3. Blend the Sauce

In a blender, combine the roasted squash (reserve a few cubes for garnish), remaining 1 tablespoon olive oil, heavy cream, and nutmeg if using. Blend until completely smooth and velvety. Season with extra salt and pepper if needed.

4. Crisp the Sage

In a small skillet, heat a drizzle of olive oil over medium heat. Add the sage leaves and cook for 30-60 seconds per side, until they turn dark green and crispy. Transfer to a paper towel-lined plate.

5. Combine Pasta and Sauce

Return the drained pasta to the pot. Pour the squash sauce over the pasta and toss to coat evenly. If the sauce is too thick, add reserved pasta water a few tablespoons at a time until it reaches your desired consistency.

6. Finish and Serve

Stir in the grated Parmesan and toasted walnuts. Serve immediately, topping each bowl with the crispy sage leaves and extra Parmesan. Enjoy the cozy goodness!

Delicious Variations

Add protein

Sauté some sliced chicken sausage or crispy pancetta and toss it in.

Make it vegan

Use coconut cream instead of heavy cream and nutritional yeast instead of Parmesan.

Switch the squash

Use roasted pumpkin or sweet potato for a different flavor twist.

How to Store Creamy Fall Pasta with Roasted Butternut Squash & Sage

Reheating
