When it comes to Thanksgiving and creating a meal that my family and friends will love, I prefer to keep the menu traditional, but have some fun with a few of the sides. I’m sure I’ve said this before, but my family looks forward to this meal every November. I know that if I didn’t make my herb butter roasted turkey with white pan gravy or my mashed potatoes, my brothers would be more than a little bummed.

To me, Thanksgiving is really more about the sides anyway. And since I like to include a few really great ones on my menu, I always have some fun with one or two and try to create a side with a bit of a (delicious) twist.

Enter this squash. It’s kind of classic, but then it’s kind of not. It’s fun, it’s easy, and most importantly? It. Is. So. Good.

I’m talking every bite is roll-your-eyes-back delicious. A little dramatic, but also very true.

Here are the details.

I’m sure many of you have roasted squash before, but roasting squash Hasselback style is a complete game-changer. I know that thinly slicing the squash might look tricky, but I have an easy way to slice it.

Start by halving your butternut squash. You want to look for small to medium size butternut squash so that each half will serve around two people. Halve the squash, scoop out the seeds, then peel away the skin.

Now place the squash on a baking sheet and roast. Instead of cutting through the squash raw, I’ve found it easier to begin roasting the squash for a few minutes to soften it up first. This makes the squash much easier to cut through.

To make the herby sage maple butter.

While the squash is softening up in the oven, make the butter. I love using Land O Lakes® Extra Creamy Butter, which has a rich buttery flavor that’s perfectly salted and melts wonderfully. Since the butter is such a key ingredient in this recipe, it’s really important to use a butter with great flavor. Land O Lakes® Extra Creamy Butter is always my go-to. I keep my refrigerator stocked at all times throughout the holidays and do my best to never run out.

Mix the butter with a splash of maple syrup and warming sage. I know the maple might be throwing some of you off, but go with me on this. It’s a sweet and savory flavor combo. The maple glazes the squash, helping it to caramelize in the oven and turn sweet, buttery, and perfect.

Slice the Squash.

At this point, the squash should be ready for slicing. Simply use a very sharp knife to cut the squash into thin slices, being careful not to cut all the way through.

I always find it easiest to rest two wooden spoons on either side of the squash to help guide you. Using a spoon on either side of the squash helps to prevent you from cutting entirely through (see photo above – I just used one spoon this time).

And don’t stress if you do cut through the squash – just roast it. It’s still going to be great.

To make the breadcrumbs.

While the squash finishes roasting, make the breadcrumbs. They’re simply torn bread, fresh sage, and prosciutto all toasted together on a baking sheet.

The salty prosciutto is KEY.

It adds a savoriness to this recipe that’s mouthwateringly delicious. It also perfectly balances the sweetness from both the maple and the squash itself.

Prosciutto Breadcrumbs on baking sheet

When the squash comes out of the oven it should be tender, with the tops crisping, and the butter melting between the layers. Any butter that’s melted onto the pan should be spooned over the squash once transferred to a serving plate.

Then just top with a sprinkling of the prosciutto breadcrumbs, and that’s it.

I know the cooking time is kind of long, but the process is easy. And I have a feeling this will be the favorite side dish for many of you this Thanksgiving. Possibly even beating out sweet potatoes.

Because really, what’s not to love with buttery, herby, roasted butternut squash topped with salty prosciutto breadcrumbs?

Absolutely delicious. And pretty, too!

Nutritional information is only an estimate. The accuracy of the nutritional information for any recipe on this site is not guaranteed.


  • 2 small to medium butternut squash
  • 4 tablespoons extra virgin olive oil
  • kosher salt and black pepper
  • 1 stick (8 tablespoons) Land O Lakes® Salted Extra Creamy Butter, at room temperature
  • 3 tablespoons maple syrup
  • 2 teaspoons chopped fresh sage + 8 sage leaves
  • 1 cup finely torn ciabatta bread
  • 3 ounces prosciutto


  • 1. Preheat the oven to 425 degrees F. Halve the squash lengthwise and scoop out the seeds with a large spoon. Using a peeler, remove the skin. Rub with 2 tablespoons olive oil, season with salt and pepper. Place on a large baking sheet and roast until the squash begins to soften, 15 minutes.
    2. Meanwhile, in a small bowl, stir together the butter, maple syrup, and chopped sage until combined.
    3. Grab the squash from the oven and transfer to a cutting board. Using a sharp knife, slice through the rounded sides of squash halves, crosswise, going as deep as possible but without cutting all the way through. I find it helpful to position 2 spoons on either side of the squash to help prevent cutting all the way through (see above photo). Return the squash to the baking sheet, scored sides up. Spread half the maple butter over the squash, allowing it to drip into the slices. Season with salt and pepper.
    4. Roast the squash for 30 minutes, then spread with the remaining maple butter, spooning any melted butter in the pan over the squash. Return to the oven and roast another 15-20 minutes, until the squash is tender.
    5. At the same time, toss together the bread, 2 tablespoons olive oil, the sage leaves, and a pinch of salt and pepper on a separate baking sheet. Lay the prosciutto around the bread. Transfer to the oven and bake for 10-15 minutes or until toasted. Crumble the prosciutto into fine crumbs or pulse the mix in a food processor.
    6. Remove the squash from the oven and transfer to a serving plate. Drizzle over any maple butter left on the pan. Top with breadcrumbs and sage. Serve warm!


To Make Ahead: roast the butternut squash through step 4, but only roast 30 minutes. Remove the squash from the oven and let cool. Then keep in the fridge for 1-2 days. To finish roasting, remove the squash from the fridge while you preheat the oven to 425 degrees F. Spread the squash with butter and finish roasting, another 20 minutes or so. 
The breadcrumbs can be made fully ahead and kept in an airtight container for up to 4 days.

  1. I made this for Thanksgiving dinner but skipped the prosciutto breadcrumbs as I was the sole cook for the day due to Covid precautions. Looking forward to making as written but I would decrease the amount of butter in the glaze- the baking sheet was a pool of butter at the end. Soooooooo good and stunning, a great reward on investment.

    This dish was a huge hit for Thanksgiving dinner this year. I even made a separate batch of the breadcrumbs for my mother-in-law who is a celiac. I also roasted the squash along side more prosciutto to have extra for crumbling on top of the finished dish. Mine had to bake longer than the recommended time but it still came out amazing!!! My family may have argued a little bit over who got the last of the butternut leftovers. I will definitely be making this again….and again….and again.

    Made this as a Thanksgiving side and it absolutely killed it!! So many amazing flavors blended perfectly to give you a mix of sweet and savory. The fresh sage added a really special touch and we all loved it. Thank you for this recipe!

  6. Hi! For making it ahead of time: do you use all the maple butter before refrigerating and then add more plain butter prior to roasting the second time? Or do you use half the maple butter for the first roasting and save the other half to add when roasting the second time? I hope that question makes sense 😀

    1. Hey Anastasia,
      You can use half and half. I hope you love the recipe, please let me know if you have any other questions. Happy Thanksgiving! xTieghan

  7. I made a trial run of this for thanksgiving it is fantastic. What’s your trick for cutting the stem in half. I love the “stem on” presentation. Great recipe!

    **Delicious** My husband and I made this + your creamed spaghetti squash last week as trials for Thanksgiving and this was the winner due to the maple syrup. This dish tastes like a grown up T-giving staple (omg the prosciutto breadcrumbs!) I’m making one for us and one to drop by my in-law’s with the turkey bacon you suggested since they don’t eat pork. We love your creative recipes and the beautiful photos you produce! Happy Holidays to you and your family.

    This was amazing, Went over super well with family and i didn’t even have proscuitto, My one idea is to put it in a larger casserole dish instead of a sheet pan so the butter can seep in better. I also put foil over it for the first 20 minutes of cooking. But still – A+!

    So delicious! And not hard at all! The only reason it’s not a 5-star rating is that I’m not a fan of butternut squash in general–I tend to get them from my CSA and need to find ways to make them less bland and mushy. This recipe does that perfectly–the long bake creates lovely dark brown edges on the bottom, with some texture, plus the bread crumb & prosciutto topping adds a ton of crunch and umami goodness. The sweetness of the maple is fine–I think I’ll add a bit more sage next time–which will be for our Thanksgiving dinner. Thank you, Tieghan! My husband got me both cookbooks for my birthday, and we have been LOVING everything I’ve made from them!

    1. Hi Elizabeth! I am really glad this recipe turned out well for you! Thank you so much for trying this one!! I hope you continue to enjoy my recipes! xTieghan

    1. Hey Christina,
      Either one would be great! I hope you love the recipe, please let me know if you have any other questions! xTieghan

  12. Love the recipe but I am so confused how to get the skin off of the butternut squash. Is it removed after cooked, do you just leave it on? Help! lol otherwise so tasty!

    1. Hey Kelly,
      I slice the skin off of the squash before cooking. I hope you love the recipe, please let me know if you have any other questions! xTieghan

      1. Hello Tieghan,
        I’m wondering if you can recommend an equally great butter alternative to Land O Lakes as it’s not available in Canada? Thanks so much!
