This Roasted Butternut Squash and Spinach Lasagna is the perfect baked pasta for cozy November and December nights with family and friends. Beautiful layers of seasonal butternut squash, creamy buttery béchamel sauce, spinach, and lasagna noodles, all come together in this vegetable-focused lasagna. It’s vibrant, creamy, a little cheesy, and so delicious! Top the lasagna with salty prosciutto before baking for a warming dinner that’s mouth-wateringly delicious. This is a great, make-ahead lasagna for Friendsgiving, Thanksgiving, and all the upcoming holiday dinner parties.

My favorite recipes this time of year are the ones that are simple to prepare, feed a big crowd, and can be made ahead of time. With Thanksgiving so close, and Friendsgiving happening all month long, recipes like this lasagna are perfect to have in your back pocket for gatherings with family and friends.
I know that this coming weekend is the big weekend for Friendsgiving here in the US. So with that in mind, I’m sharing not only this delicious (almost vegetarian) lasagna, but all my best tips and tricks for hosting!
It’s probably no secret…because I’ve said this a million times over, but lasagna is my go-to dish for entertaining. Every year I love to come up with a new recipe to share. This butternut squash lasagna is my personal favorite. Sure I really love a classic lasagna, but my true favorites sway more towards anything with butternut squash. Add a buttercream sauce and you’ve sealed the deal.
Start off with the squash. It’s simply roasted, then mashed, and stirred together with creamy ricotta cheese. I like to use a lot of squash to get a really great flavor and color.
While the squash is roasting, make the béchamel sauce. As always, I used my Aunt Katie’s base recipe for this sauce, as I’ve yet to create a better version. It’s a delicious mix of garlic, sage, rosemary, spinach, and buttery gouda cheese.
But her real secret to a great béchamel? A generous amount of butter…the key to everything this time of year. I used Vermont Creamery Cultured Butter for especially delicious flavor, richness, and creaminess. Using high-quality ingredients are so important to me. I love knowing that they use only two simple ingredients: cream and cultures (and sea salt if you’re using the salted butter).
Unlike traditional butter, Vermont Creamery’s Cultured Butter is fermented for 20 hours then churned to 82% butterfat. This provides the butter with an incredibly rich taste and creamy texture. It has a delightful tang and notes of buttermilk and hazelnut, which pair so nicely with the warming herbs and spices I’ve used throughout this recipe.
Once the squash has been roasted and the sauce made, simply layer everything together with easy, no-boil lasagna noodles.
Now, this next ingredient is optional, but one I really do love. Prosciutto. I like to add a little salty prosciutto to the top of the lasagna before baking. As the dish bakes, the prosciutto crisps and adds a really nice salty flavor.
Of course, if you’re vegetarian you can easily omit this!
I really can’t begin to describe just how delicious this roasted butternut squash and spinach lasagna is. Something about these flavors all layered together and baked is just beyond GOOD. The squash has an amazing caramelized flavor from slow roasting. And the sauce is incredibly rich and creamy and brightens up with the addition of spinach. When everything is put together, you get a rich, creamy, and super cheesy pasta. Every last bite is DELICIOUS!
tip one: start with a cooking schedule. This is KEY. I spoke about this in more detail last year, but I have to note this tip again. Once you have your menu set, plan out when each dish needs to be going into the oven, and when it’s coming out. Writing out a game-plan is the most helpful tool for creating a laid back, stress-free night, full of delicious food.
tip two: assign guests dishes to bring to your dinner. Trust me, there’s no reason you need to be making ALL the food. Make your favorite recipes, and have friends and family bring everything else. Just be sure you assign everyone what they need to bring. That way you won’t end up with multiple sweet potato casseroles.
tip three: make/prepare as many recipes as you can ahead of time. Don’t plan any recipes that require you to hover over the stove all night long. It’s best to work with recipes you can assemble in advance, like this lasagna!
tip five: set the table the night before. I can’t stress this one enough. If you want a nicely set table, set it the night before…or even the week before. My grandma taught me this tip and it’s the only way I can guarantee a beautifully set table. If I try to do it the day of I always run out of time.
Hoping this helps you all create an amazing night with family and friends!
PS. if you’re looking for a great salad to go along with this hearty pasta, I highly recommend this. It’s always a crowd favorite.

Hello! I was wondering if I could assemble and bake this lasagna in a 12×17 inch baking sheet like your sheet pan lasagna recipe? Would I need increase the ingredients? I absolutely love the sheet pan format and want to use it on every lasagna I make in the future! Thank you 🙂
Hey Sophia,
I think that sounds like a great idea, I wouldn’t think you would need to increase anything:) I hope you love this recipe! xT
I am making this for thanksgiving! If I already bought traditional lasagna noddles (not no bake), would I adjust the recipe/pre cook the noodles? or what adjustments would you recommend?
Thank you!
Hi Melissa,
Yes, I would cook your noodles according to packages directions first:) I hope you love this dish, let me know if you give it a try! xT
This was delicious. Very VERY rich which meant our portions were small and we served a light house salad on the side. Perfect for a comfort meal in cold weather. This was good the second day as well!
Hi Melissa,
Thanks so much for making this dish and sharing your review, so glad it was delish! xx
I’ve made this several times now because my family requests it several times during the Fall & Winter holidays. It never disappoints. I rarely follow a recipe BUT not in this case. This recipe is spot on! I don’t have to tweak it at all. …& the prosciutto is a must in my Italian home! I appreciate the sharing of recipes. Thank you!
Hey Zia,
Perfect!! Thanks so much for making this recipe, I love to hear that it turned out well for you! xT
The flavors in this lasagna are delicious and the recipe easily riffable! I found the bechamél to be pretty watery, so ended up having to make and add more roux to thicken – either a bit more flour or a bit less liquid next time. Added some roasted hazelnuts and fried sage leaves on top for some extra crunch. Yum 🙂
Hey Kellia,
Happy New Year!!🎆 I love to hear that this recipe was a winner, thanks so much for giving it a try and sharing your review! xT
I’ve been a HBH fan for years, and I can say without hesitation that you are my favorite chef that I follow. I make on average one HBH recipe per week, and this recipe tonight was one of our absolute favourites! And that’s saying a lot, given how many recipes I’ve made of yours. Thank you for this absolutely incredible meal! It will be a regular for years to come. Thank you!!!!
Hey Whitney,
Happy Monday! Thanks so much for giving this recipe a try, I am so glad it turned out well for you! Thanks for your comment and super kind message! xT
