Why this recipe works
This pasta dish features a rich, creamy butternut squash sauce and chunks of tender roasted squash, so it's perfect for the Fall and Winter. But it's really a great meatless dish any time of the year.
I'm by no means a vegetarian, but sometimes, for a meal or two, I need a little break from meat. This dish and my veggie lo mein are two of my favorites for those days.
If you roast the squash ahead of time, this dish can also be great for a quick weeknight meal that you can have on the table in around 20 minutes!
What you'll need
- Butternut squash - I used one medium-sized squash, but you can buy it pre-cut in most grocery stores to save time.
- Pasta - I used fettuccine because I like to use a wider noodle with a creamy sauce, but any will work, so choose your favorite.
- Heavy Cream
- Vegetable Broth - you can use chicken broth instead if you'd like.
- Parmesan cheese
- Seasonings - Brown sugar, dried thyme, salt and pepper
- Fresh Sage - optional for the garnish
How to cut butternut squash
Butternut squash can be difficult to cut. There are lots of different recommended methods on the web. Some use a vegetable peeler, some use a knife, and some even microwave it for a few minutes to soften it up. I like to use a knife and break it down in two pieces.
First, lay it on its side and, using a large chef's knife, cut off the top just under the stem, then cut off the very bottom. Next, cut the neck of the squash off just above the bulb leaving two pieces.
The neck section is fairly easy to handle since most of the cuts are straighter. Just stand it up vertical, then use your knife to make downward cuts to peel off the skin. Once you have it peeled, cut it into large chunks.
The bulb portion of the squash is a little more difficult since it's curved. First, stand it up vertical and make downward cuts, trying to curve around the shape of the squash. When the skin is thick, it can be very tough to turn your knife when making those cuts, so just do your best and clean it up with smaller cuts if needed.
Once you've got the bulb portion peeled, you'll need to cut it in half and scoop out the seeds. They're delicious roasted. Then, cut the squash into chunks.
Toss the chunks in olive oil until well coated the season with brown sugar and some thyme. Arrange in a single layer on a sheet pan and roast at 400 degrees F for around 25-30 minutes.
How to make the creamy butternut squash alfredo sauce
- First, add half of the cooled squash to a blender or food processor with the heavy cream and puree until smooth.
- Transfer the squash mixture to a large skillet over medium heat and stir in your broth. Bring this to a low simmer and cook it for 2-3 minutes, stirring occasionally.
- Stir in your Parmesan cheese. Simmer the sauce for another minute or two until it reaches your desired consistency. If it's too thick you can stir in a little more broth or some of the pasta water.
- Then add the pasta to the pan and toss until all of the pasta is coated.
How to serve butternut squash pasta
To serve the creamy roasted butternut squash pasta, portion out the pasta into bowls or plates. Then top the pasta with the remaining chunks of squash. Garnish each plate with some fresh chopped sage and some Parmesan cheese and serve immediately.
For side dishes, I recommend a simple fresh salad and a big batch of homemade garlic bread.
