Pasta with Butternut Parmesan Sauce

Pasta with Butternut Parmesan Sauce

One of the best things about fall is the abundance of pumpkins and hardy winter squash. Ever wonder why winter squash is called "winter" squash when it first makes its appearance in the fall? Perhaps because if stored in a cool place, they'll last several months, well into winter. Anyway, butternut squash is the queen of winter squashes. The taste is so good, and so consistent, that from what I understand, most "canned pumpkin" that we use to make pumpkin pie is actually made with a variety of pumpkin more akin to butternut squash than to the pumpkins we use for jack-o-lanterns. (See Canned pumpkin is it really pumpkin?)

The ever fabulous Garrett came over recently with a pint of roasted butternut squash purée and a mission to create a pasta sauce with it. We often find butternut squash inside of ravioli, why not on the outside? It just needed to be thinned a bit with cream, made savory with Parmesan, and brightened with some acid (from lemon juice) and parsley. The result was absolutely delicious; I ate the leftover sauce with a spoon straight out the fridge for days. The way we made it was chunky, with a little crunch from the shallots, but if you wanted it smooth, you could easily purée it some more or pass it through a food mill.

Pasta with Butternut Parmesan Sauce Recipe

The sauce has the consistency of chunky tomato sauce. If you would like your sauce to be smooth, you can run it through a food mill.

Ingredients

  • 1 butternut squash weighing about 2 1/2 pounds
  • 8 ounces of bow-tie pasta
  • 1 tablespoon of olive oil
  • 1/3 cup of chopped shallots
  • 1/2 cup of packed, freshly grated Parmesan cheese
  • 1/2 cup of heavy cream
  • 1/8 teaspoon of grated nutmeg
  • 1 tablespoon of chopped parsley
  • 2 teaspoons of lemon juice
  • Salt and pepper to taste
  • Water as needed to thin the sauce

Method

1 Preheat the oven to 350F. Cut the butternut squash lengthwise in half* and scoop out the guts and seeds and discard them (or save the seeds and toast them). Pour 1/4 cup of water into a pyrex or ceramic baking dish and place the butternut squash halves cut side down. Bake for 40 minutes or until a fork easily pierces the squash. Allow to cool for 10 minutes. Scoop out the squash flesh from the skins and purée with a blender (work in batches or place in a bowl and use a hand blender). Discard the skins.

2 Fill a pot with water and salt (1 tablespoon of salt for every 2 quarts of water). Set over high heat to bring to a hard boil. Add the pasta and cook at a hard boil, uncovered until al dente.

3 While the pasta is cooking, pour the olive oil into a wide skillet on medium heat. Add the shallots and sauté until soft and translucent, about 5 minutes. Add the butternut squash purée and cook for about a minute, mixing it in with the shallots. Add the cream, a tablespoon at a time, slowly stirring it in to incorporate and to avoid lumps. Stir in the Parmesan. Add the nutmeg, salt and pepper. Add water (or chicken stock) to thin to the consistency you want. Take off heat and add the parsley and lemon juice. Cover the pan to keep warm.

4 Check pasta. When ready (al dente) drain and plate. Pour the sauce over the pasta. Garnish with a little extra parsley and Parmesan. Serve immediately.

Serves 4.

*Be careful when you cut the squash, winter squash are hard! The best way to do it safely is to slice a bit off of both ends so that you can stand the squash upright without it rolling. Then cut down the middle. See how to cut and peel a butternut squash for visuals, though note for this recipe you do not want to peel the squash before roasting.

This sounds delish! I love butternut squash with cheese and pasta. It is one of those combos that really works, and makes my mouth water! I bet the lemon really makes the flavors pop.

Wow, that looks amazing.

Posted by: Lindsay on November 14, 2009 12:38 AM

I knew I froze those two containers of squash puree for a reason!

Posted by: pam on November 14, 2009 4:58 AM

I am drooling!! This looks delicious!! I've been thinking recently of making a paste dish with pumpkin. Thanks for the extra inspiration!

Posted by: Sarah on November 14, 2009 5:21 AM

Wow, must try this. I normally oven roast chunks of butternut squash and mix with pasta topped with a boursin cheese and sage sauce. I'll have to try this, but will add sage since they go together so well. Thanks..

Posted by: KissTheChef on November 14, 2009 6:21 AM

This looks amazing! I'm really excited to try it.

Do you think I could replace the cream with some broth to help thin it out? Or would it not get the same texture?

You could try it. Let us know in the comments how it turns out if you do. ~Elise

Posted by: Andrea on November 14, 2009 6:24 AM

What type of meat topping would go well with it?

Your guess is as good as mine. I wouldn't add meat to this. ~Elise

Posted by: Sketchy on November 14, 2009 6:42 AM

I like to mix it with some ricotta cheese as well for a nice smooth and creamy sauce for pasta. I've been waiting to get butternut squash from my CSA but might actually have to go buy one to make this as you have me salivating!

Posted by: Cooking with Michele on November 14, 2009 7:10 AM

I've never tried canned pumpkin...do you think it might be a good substitute if you're trying to create the meal a bit more quickly (with lower risk of chopping off fingers as well)?

I'm guessing that you could use canned pumpkin, as long as it was just canned pumpkin, not the already seasoned kind (with cinnamon, nutmeg, etc.) If you try it with canned pumpkin, please let us know in the comments how it turns out. ~Elise

Posted by: Yana on November 14, 2009 7:14 AM

I make something similar to this but use a good Gruyere and add sage. It's incredible over gnocci! Also, I use a thicker version, sans the sage and Gruyere, as a lasagna stuffing and cover the whole thing with a Gruyere and sage mornay sauce. Heaven on a cold winter's night with a good crusty bread and a great red wine!

Posted by: Lee on November 14, 2009 7:34 AM

Recipe sounds delightful! I will try this tomorrow night.

One easy (and safer) way to cut butternut squash is to soften it in the microwave first. prick the squash with a fork several times, stick the squash in a microwave for 7 minutes, and then cut in half. Scoop out the seeds, and then roast the halves in the oven. The microwaving also cuts down the roasting time by about 25%.

Posted by: dcirene on November 14, 2009 8:09 AM

Hey, I have a quick question: if you wanted to make this with frozen butternut squash, how much would you use? Yes, yes, I know, it's better to make your own puree, but if one is in a hurry?

I would guess a couple of pounds. ~Elise

Posted by: GoneVeg on November 14, 2009 8:24 AM

This looks delicious! I've been on a mission to make as many possible recipes with butternut squash this season - it's so versatile. I love this idea, thanks!

Posted by: arugulove on November 14, 2009 8:40 AM

I have a tiny butternut squash that I've been wondering what to do with... this recipe (halved) looks like it will be perfect (and delicious!).

Posted by: Sara on November 14, 2009 8:56 AM

Is the pasta amount correct? 4 ounces seems like a small amount for the amount of sauce!

You're right! When Garrett and I made it, we only made enough pasta for two people (though enough sauce for 4). I've doubled it now in the ingredient list to where it should be for 4 people, which is 8 ounces. ~Elise

Posted by: suzette seagoe on November 14, 2009 9:14 AM

This is delicious. You actually don't have to skin the butternut at all before pureeing it. You can roast it in olive oil at 425 for about 25 minutes and the skin softens up deliciously. Also, goat cheese adds a nice flavor instead of parmesan, and use nonfat greek yogurt instead of the heavy cream to keep it healthy and still creamy!

Yes, there is no need to peel the butternut squash for this recipe. After roasting you can easily scoop out the flesh. Thank you for the suggestions of goat cheese and greek yogurt, they would work well. ~Elise

Posted by: Jerrod on November 14, 2009 9:25 AM

What a great way to enjoy some winter squash!

Posted by: Kevin on November 14, 2009 9:55 AM

This looks DELISH and I'm gonna try it this week - someone asked about replacing the cream with broth - do you think a rice or soy milk would do fine as a replacement also? Is the cream just a thickener? Trying to avoid milk products here....

I would use broth over rice milk or soy milk. But it is going to be hard to avoid milk products if you keep in the Parmesan. If you skip the cheese too, then the recipe is more challenging. You might try starting out with a base of shallots and anchovies, sort of a riff off the pasta with cauliflower recipe we posted recently. ~Elise

Posted by: Ericka on November 14, 2009 10:09 AM

I am always looking for more recipes for Butternut squash beyond my usual Butternut Squash soup.. so this recipe is a great add on. I might just fill in canelloni with the sauce...I am sure my family will love it. Merci!

Posted by: Gaelle@whatareyoufeedingyourkidsthesedays.com on November 14, 2009 11:08 AM

How can I make this low-fat? I like to avoid using heavy cream. Is there a good substitute?

You might try substituting the cream with chicken stock as another commenter suggested. ~Elise

Posted by: arielle on November 14, 2009 11:39 AM

As soon as I saw this, I immediately thought "Oh, yeah, baby!" I love winter squash - especially butternut. Yum!

Posted by: Alta on November 14, 2009 11:49 AM

To cut the squash: If my husband doesn't do it, I use a chef cleaver and hit it with a rubber mallet(that I use for tenderizing or flattening out chicken)works every time very nicely.
I love the idea of sage. We go to this restaurant in Naples,FL. called Naples Tomato and they serve a butternut squash ravioli with sage and butter....YUM
Going to try this one. Thanks for this recipe.

A rubber mallet is a useful tool for cutting butternut squash. ~Elise

Posted by: Sunny on November 14, 2009 12:30 PM

You have such a nice way of working in that little touch of sweet spices -- the nutmeg is perfect. Tried this with the thick greek yogurt (regular, not nonfat, but still lighter than cream); it was delicious, and since I already had some fresh butternut roasted and ready in the freezer, it made up real quick and simple. What I had in the house was small pasta shells, and they caught up the sauce beautifully. I didn't think of it until later, but what do you think of incorporating the squash seeds, lightly toasted in a little olive oil? scattered over the top, or folded into the pasta?

I think roasted shelled pumpkin or squash seeds would be lovely over the top. The seeds with the shells still on would be a little too tough for this dish. ~Elise

Posted by: mantha on November 14, 2009 1:08 PM

Okay... we're headed to the store right now to get some of the ingredients - the rest we have. How silly excited can a mom and daughter be about some squash, cheese and pasta?!

Posted by: Simone on November 14, 2009 3:09 PM

I just made this with Fage Total Greek Yogurt and it worked fabulously.

Posted by: Nana on November 14, 2009 4:08 PM

This sauce would make a yummy soup, served with crusty bread. What do you think?

I think it's a bit too rich for a soup, but if you make it into one, please let us know in the comments how it turns out. ~Elise

Posted by: Elizabeth (Australia) on November 14, 2009 4:37 PM

Sounds great. I love butternut squash. FYI, I have found the absolute best way to cut winter squash is to heat it whole in the microwave for 3 minutes. Then it's easy to slice in half before roasting. Try it, it really works!

Posted by: Regina on November 14, 2009 6:14 PM

Oh my goodness...the 4 recipes today look like you and I were chatting together and you posted them just for me. I am so excited! Love butternut squash...with pasta, what could be better? B. sprouts are one of my favorite veggies and I drool for black bean sauce. Loved you story of your nephew and kids not liking components of a recipe. It has always made me shake my head when someone likes all the parts of a recipe but they don't want them together...eh, what? Last, but not least was your cauliflower with anchovies. Love roasted veggies (broccoli is my new fav) and have had to deal with comments from others when I would order pizza with anchovies. (Smells like cat food? At least I didn't have to share.) I too have outgrown my younger dislike of country music too...were we separated at birth? Happy dining!!!

Posted by: sue on November 14, 2009 6:31 PM

Nice combination of ingredients. I was just thinking about it, if you replace the cheese in here with butter instead, add some saffron and a few other Indian spices and cook it with chicken pieces this can come pretty close to Butter Chicken. Thanks, this has now inspired me to try this with chicken. I will post as to how it turns out.

Posted by: Sriram on November 14, 2009 7:04 PM

I bought 2 big butternut squash today, they were on sale for $0.50
a lb. They are so good with rice. Olive oil. garlic, onions bite size
butternut squash, green beans. 1can of cocunut milk then shrimp.
salt to taste. (cook in that order) Amazing!

Posted by: mareza on November 14, 2009 7:46 PM

Pre-roast butternut squash is just the handiest thing to have about at this time of year. Add chunks to salads, turn it into soup or pie filling, or if it's really sweet I love to puree it, put it in a little pudding bowl and top with maple syrup and a dash of cinnimon as a snack. Thanks for another inventive recipe idea here.

Posted by: Heather (The Momshell Diet) on November 14, 2009 8:45 PM

Ooh, this I will have to try - thanks Elise! I make a very similar recipe that I got from Rachel Ray - it uses 1 cup of canned pumpkin (which is a great substitute, as one commenter asked), fresh sage (plays great with nutmeg!), and sliced chicken sausage. The meat is optional, of course, but it helps make a hearty dinner.

I really, really love this version, though - I like the great amount of shallots and chunky texture. I would use half-and-half cream instead of heavy cream; that would help cut down on fat (although nonfat Greek yogurt would probably work, too).

Posted by: Katherine @ NightOwlChef on November 15, 2009 7:21 AM

Living in Illinois, where the majority of pumpkins (and canned pumpkin) in America are grown and canned, I can tell you that most canned pumpkin is... Pumpkin.

Check the label. Yes American labeling are the among the world's weakest, but even in America they couldn't say pumpkin if it isn't. I've never seen one where butternut squash is among the ingredients.

That said, the recipe is WONDERFUL. And we used frozen butternut squash as that was in the freezer and we had no fresh squash laying around.

Most pumpkins that we buy aren't even true sugar pumpkins, but some hardier variety of winter squash. I don't think the label is an indication, it would be like distinguishing between patty pan and gooseneck summer squash, when it's all summer squash, and the label could read zucchini and would still be accepted. That said, if someone from Libby can tell us the actual varieties of winter squash used in making canned pumpkin, please speak up. ~Elise

Posted by: Leo Cironis on November 15, 2009 8:10 AM

Looks absolutely delicious! I wonder if it would taste good with a little roasted red pepper?

Posted by: Kelly on November 15, 2009 8:46 AM

I made this last night, as written and it was delicious! I'm going to try it with Greek yogurt and Gruyere as noted by Lee. Thanks for all of your wonderful recipes, Elise..

Posted by: Dorothy on November 15, 2009 1:47 PM

I think butternut squash may be my favorite veggie and I love it pared with pasta. This looks like a wondeful, creamy sauce, perfect for fall and winter meals. We used to store this squash in our basement away from any heat for a large part of the winter.You have to check them every few days for any sign of spoilage, but most of them keep well.

Posted by: Lynda on November 15, 2009 1:59 PM

What a great way to use all the squash that's in season! Can't wait to try it.

I just discovered this website today, but I'm pretty sure I'll be coming back here often - the gorgeous picture of the sloppy joe's literally made my mouth water, and this recipe looks equally appetizing. Plus, the recipes are easy to follow. Yay!

Posted by: Ashley Fahr on November 15, 2009 5:16 PM

Can't get enough of savory pumpkin and squash, thanks for this! Another combination in the same family is sweet potato and feta or goat cheese. You could make a sauce, or you could simply slice the sweet potato into rounds (keep skin) and top with goat cheese and herbs. A surprisingly healthy appetizer for the wow factor.

Posted by: Porter on November 15, 2009 5:54 PM

I make a similar sauce out of blended cottage cheese and canned pumpkin (yes, really butternut, you're right!) seasoned with sage and nutmeg. I serve it over pasta with caramelized onions, spinach and chicken sausage. It's one of my favorite things! I have had many a moment explaining to people that canned pumpkin is not actually the jack-o-lantern variety, or even the sugar pumpkin. I use butternut and buttercup pretty much interchangebly with pumpkin!

Posted by: Cara on November 15, 2009 6:02 PM

I couldn't wait to try this recipe and made a half recipe for dinner tonight. It was delicious, but even after adding a few more tablespoons of cream, it still had the consistency of mashed potatoes. I didn't have time to work out any modifications at the time, but I think next time I'll add some broth to make it more of a sauce consistency.

Posted by: Paige on November 15, 2009 7:36 PM

I too make a similar sauce with canned pumpkin. One reader asked about meat - I have used sweet Italian sausage (sometimes turkey sausage), and the savory aspect compliments the great fall flavors.

Sometimes I also throw in other things: mushrooms, tomatoes, or even black beans. My 2-year-old daughter LOVES it!

Also, instead of cream I often use plain yogurt. You just need to make sure to slowly warm it with a small amount of sauce to prevent it from curdling.

Posted by: Sara on November 15, 2009 7:52 PM

Thanks for a great recipe - I just made it today and it was DELICIOUS. I'm completely in agreement on eating it with a spoon straight out of the fridge. The leftovers won't last long!

What a wonderful colour, it looks and sounds delicious. Perfect for autumn

Posted by: Snack-Girl on November 16, 2009 7:43 AM

I'm so excited to make this! Thank you for posting this recipe, i'm always looking for new ways to eat squash.

I love your site, Elise! :) Keep up the wonderful work that we all aspire to!

Posted by: Sunny P on November 16, 2009 2:18 PM

Ack! Let TWO pots boil over on the stove, I was so distracted by this recipe! No shallots on hand... is there an acceptable substitute?

Sure, onions. ~Elise

Posted by: Kathryn on November 16, 2009 5:32 PM

What an original idea! I adore butternut squash ravioli, but have never considered using the squash in this way. Much less time-consuming!

Posted by: Dara on November 16, 2009 7:55 PM

I made this for my parents last night, and while it was very tasty (I substituted plain Greek yogurt for the heavy cream as well), it was very dense. I think next time I will use some chicken stock to thin it out a bit so it's more like a sauce consistency and less like a mac and cheese consistency. Very good though - very very sweet! I'm wondering if the smaller the squash, the sweeter the flavor? It was a 2lb squash...

Also - I added toasted pine nuts on top, and it gave it the little bit of extra flavor it needed :)

Posted by: Toni on November 17, 2009 5:51 AM

Can't wait to try this. Love the cream and cheese in there! Sounds super, and it's just the thing for this time of year, when I always look for new ways of using the abundant squashes at farmers' market.

Posted by: Lisa on November 17, 2009 8:34 AM

I just made the recipe last night for my husband and we both loved it. As a time saver, I went to Trader Joe's and purchased the pre-cut butter nut squash cubes and steamed them. I will use the whole squash when I make this for my vegeterian friends for Thanksgiving! Thanks for this wonderful dish.

Posted by: Kate on November 17, 2009 9:01 AM

My new favorite pizza place has pizza made with butternut squash sauce, carmelized onions, spinach and gorganzola cheese. I had been looking for recipe for a similar sauce to make it at home. This dish will be an easy alternate for my autumnal cravings!

Posted by: Beth on November 17, 2009 10:40 AM

I made a version of this last weekend. I bought a box of frozen Birdseye Butternut Squash and defrosted it in the fridge.

I sauteed up a big pan of chopped sweet onion, sliced mushrooms and red bell pepper seasoned with salt, pepper, garlic, sage and oregano and deglazed the pan a bit with balsamic vinegar.

When the veggies were soft, I added a few chunks of frozen spinach to the pan and let that sit in the hot pan to defrost. When the spinach was soft enough I mixed it in and then sprinkled the whole pan with a bit of granulated chicken bouillon. Then, I mixed in the squash puree and finally finished it off with a small can of evaporated milk. The tiny can was the perfect amount of milk to make the sauce a smooth consistency. I used the sauce on whole wheat pasta topped with parmesan and really LOVED IT!!!!!!

Posted by: Jen A on November 17, 2009 3:26 PM

I just made this for dinner tonight. Maybe my Parmesan cheese is particularly strong, but 1/2 cup of cheese was just too much. It totally overpowered the squash flavor. I also think I will thin it out with some broth next time. Thanks for the recipe!

Posted by: Jill on November 17, 2009 5:00 PM

This was really YUMMY! I didn't have bowtie pasta; I used whole wheat spaghetti, instead and it was wonderful. The next day I had plenty of the sauce left over (I guess my butternut squash was a little bigger than I needed). I cut it with chicken broth and had wonderful squash soup with crusty bread. This recipe is a keeper!

Posted by: Sue Renault on November 17, 2009 5:29 PM

Could you make this with acorn squash?

I think the acorn squash might be a little fibrous for this dish. But if you try it, please let us know in the comments how it turns out. ~Elise

Posted by: Kezza on November 18, 2009 8:12 AM

Oh Elise....! Roasted butternut and pasta were made for each other. I made a butternut, feta and chicken lasagna the other day which was just marvellous - this recipe of yours is alreay bookmarked to try :)

Posted by: Jeanne on November 18, 2009 8:21 AM

I made this Sunday night with a squash that was still out in the garden. Although I usually roast butternut with cut side up, the comments about thick sauce encouraged me to roast this one skin-side up, in water, as suggested. Used half-and-half plus a little butter, as it was what I had. I had no trouble with sauce consistency, and it was great!

I agree with one of the posters above: it's not necessary to remove the skin before pureeing, unless it's charred. I often cube my squash skin-on, for use in dishes. YMMV.

Posted by: Mac on November 18, 2009 4:29 PM

I wanted to like this. I really did. It didn't really have any taste to it. I made it to the T. used really good parmi and still, didn't care for it. It needed some other texture, something crunchy maybe.

Sorry Elise...but I did love other recipes that I've tried.

Sounds like it was underseasoned. I would add more salt and pepper. ~Elise

Posted by: Mary on November 18, 2009 6:57 PM

This is amazing. Even after I burnt the onions it was still delicious. Mine was very creamy though, it tasted just like butternut squash raviolis except 100x easier to make.

Posted by: Adam on November 19, 2009 6:55 AM

I made this last night, and the taste was phenomenal. Great combination of ingredients. Mine was way too thick, though...is chicken broth the answer to make it a little more thin?

So glad you liked it! BTW I've added a note to use water or stock to thin to desired consistency. ~Elise

Posted by: Amanda on November 19, 2009 8:39 AM

I made this last night and it was delicious. I pureed my squash until it was really smooth so my sauce was really silky. Instead of serving it with the sauce on top, I mixed the sauce in with the pasta. It looked just like packaged macaroni and cheese (which I never make) so I had to warn my husband that the orange wasn't cheese, despite appearances. He still liked it though! I served it with a simple salad with romaine, gorgonzola, thin gala apple slices and toasted walnuts with balsamic vinaigrette. YUM!

Posted by: Katrina on November 19, 2009 10:44 AM

I made this last night and it was delish! I am not a squash fan, but have lately discovered some wonderful recipes using butternut, kabocha and delicata, and am becoming a convert. This will definitely go into my repertoire of fall recipes. Thanks for a truly lovely dish!

Posted by: Karen on November 19, 2009 1:26 PM

This turned out great and was absolutely delicious. After nearly every bite I said, "Mmmmmm." I will definitely be making this again and sharing the recipe with friends. Kudos to you and Garrett for this awesome recipe.
