More Winter Squash Recipes

Among the rich produce of winter, I take a liking to winter squash. These are very durable and versatile vegetables, which have a hard and thick skin and tender texture inside. You can get a variety ranging from sweet to savory tasting.

And there’s no one way to make them. You can puree it and pair it with other fall produce like sweet potatoes into soups like in this Sweet Potato Pumpkin Soup done in an Instant Pot. Enjoy the sweetness of a simple Pumpkin Soup.

Make classic Italian comfort food like risotto with butternut squash or use sweet chunks of it with a Thai curry base and make this Thai Butternut Squash Curry.

Cutting Butternut Squash

Butternut squash is a hard variety of winter squash. Probably the only time-consuming part of this recipe is peeling and cutting the squash. But a sharp knife, a vegetable peeler, and a sturdy chopping board should do the job.

Start by trimming off both ends. This will make peeling and cutting easy. Peel the squash whole, then cut it into half lengthwise. Using a spoon, scrape out the seeds.

Cut into 1–1.5-inch cubes. Smaller chunks take less time to cook.

Peel and cut butternut Squash to half. Remove the seeds and pulp.
Chop butternut squash to 1 inch cubes.

One more reason to love this pasta is that you can easily sneak in the veggies, and any fussy eater would devour it.

If the number of steps and time taken to make this worries you, the good news is, that you can plan this cook over 2–3 days. Few of the steps are make-ahead. You can roast the squash and veggies a day or two before. Then, while you cook the pasta, blend the sauce and make the breadcrumb topping.

To make clean-up easy, line the baking tray with parchment paper.

Steps to Make Butternut Squash Pasta

Cut the veggies: Cut butternut squash into 1-1.5 inch cubes. Roughly chop onions and peel garlic.

Roast: Toss chopped squash, onion, garlic, rosemary springs, salt, and pepper along with olive oil. Roast until the squash is fork-tender and caramelized.

Parmesan Breadcrumb Toppings :

Melt butter and sauté garlic until aromatic. Add breadcrumbs and finely chopped rosemary. Saute until the bread crumbs are crunchy and golden brown in color.

Let the breadcrumb come to room temperature, then add shredded parmesan cheese. Mix everything and keep it aside.

Cook Pasta: While the veggies are in the oven, bring a pot of water to boil. Salt it well and cook pasta al dente. Reserve 1 cup of pasta water, to use later if required.

Blend: Scrap the veggies from the baking tray. Blend it along with chicken stock and heavy cream, to a smooth sauce.

Add the butternut squash puree to cooked pasta and a small pinch of nutmeg. Mix gently using a spatula. Add reserved cooked pasta water to adjust the consistency.

I prefer using tubular pasta like penne or rigatoni. Fussili also holds the sauce well. But you can use any pasta you prefer.

Rosemary, thyme, or sage all of these herbs work really well and have fall flavors.

What can I use instead of butternut squash?  

Any winter squash will do. The most common winter squashes are acorns or pumpkins. It needs to be ripe and sweet

Make Ahead and Storing Leftovers

If making ahead you can roast the veggies 2 days prior and refrigerate. On the day of serving while you cook pasta, blend roasted veggies to make the sauce.

You can also make the pasta sauce 2 days in advance and refrigerate.

Leftovers can be stored in the refrigerator for up to 2 days. The pasta might soak up the sauce, so you can add some warm chicken stock or water to loosen it.

    Loved it! Roasting the squash & garlic makes a huge difference in the flavor as opposed to boiling it.
