And to balance the sweetness there is crunchy garliky parmesan breadcrumb topping. This bowl of butternut squash pasta is like a bowl of mac and cheese but with fall/winter vibe.
Cutting Butternut Squash
Butternut squash are the hard variety of winter squash. Probably the only time consuming part of this recipe is to peel and cut the squash. But a sharp knife, vegetable peeler and a strudy chopping board should do the job.
Start by trimming off both the ends. This will make peeling and cutting easy. Peel the squash whole then cut into half lenght wise. Using a spoon scrap out the seeds.
Cut into 1 - 1.5 inch cubes. Smaller chunks takes less time to cook.


One more reason to love this pasta is, you can easily sneak in the veggie and any fussy eater would devour on it.
The steps and time might put you off. You can plan this recipe over 2-3 days. 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 a parchement 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 saute garlic until aromatic. Add breadcrumbs and finely chopped rosemary. Saute until the bread crumbs are crunhy and golden brown in colour.
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 sacue.
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.

Substitutes
I prefer using tubular pasta like penne or rigatonni. 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 has fall flavours.
What can I use instead of butternut squash?
Any winter squash will do. The most common winter squashes are acorn or pumpkin. It needs to be ripe and sweet.

Make Ahead & Storing Leftover
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 refrigirate.
Leftovers can be stored in the refregirator upto 2 days. The pasta might soak up the sacue , so you can add some warm chicken stock or water to loosen up.

Serving Suggestion
Along with breadcrumb topping, crispy bacon bits pairs well. A good green salad can be served as side. Add some protein like Parmesan Crusted Chicken, Italian Chicken Cutlets or Air fryer crispy Chicken Breast to make it a complete meal.
