How to make a Butternut Squash and Spinach Lasagna
- The first step to this lasagna is addressing the butternut squash. You can purchase it whole and chop it into small little cubes or buy it precut. Either way is fine but what isn’t negotiable is roasting it. Yes, I know it takes a little time, but roasting ANY vegetable intensifies the flavor, browns it and in this case even caramelizes it.
- Once the squash is cooled it gets added to the food processor along with some creamy ricotta cheese, a little milk, salt, pepper and nutmeg and pureed until it is so creamy. Can you leave it a little chunky? It’s all up to you.
- To add dimension and flavor to this lasagna, we added a layer of sauteed spinach with some finely diced onions and garlic and combining that with ricotta and mozzarella cheeses. All that’s left to do is assemble it.
HOW TO ASSEMBLE:
- Spray the bottom of a 9 x 13 pan with cooking spray and spoon in enough of the butternut squash puree to lightly coat the bottom.
- Lay down 3 noodles and spread the butternut puree on top, nice and thick.
- Next layer on the spinach and ricotta mixture.
- Finish with a little mozzarella cheese.
- Repeat this 3 more times finishing with mozzarella cheese and sprinkle some parmesan on top too.
- Cover it and bake for about 30 minutes. Then taking the cover off and broiling it for a few minutes to get the cheese nice and bubbly golden hot.
If you like butternut squash I really think you won’t be disappointed by giving this a try. The flavors in this lasagna are nothing short of magical.

I have a bumper crop of butternut squash this fall. YAY!! This recipe looks delicious and my picky hubs who isn’t really a fan of traditional lasagna (he prefers white sauces) would like this. Question: could this be made using jumbo pasta shells? He loves them and I thought I could use the filling to stuff them with.
Hi Amanda! Yes! This butternut filling would go great in shells – or you could even make your own crepes!
This was soooo good! It reminded me of butternut squash ravioli which I absolutely love!! I figured out how I could make it as ravioli but am wondering if you have any sauce suggestions for the top? I searched and found a brown butter sage sauce… do you think that would go with this recipe? Meaning, would the sage match the flavors of the filling?

Hi Heather! I just had butternut squash ravioli the other day and I used this sauce https://happilyunprocessed.com/butter-garlic-cream-sauce/. I love butternut anything, especially ravioli. Enjoy!
My whole family LOVED this recipe!!!
★★★★★
Thanks Alli – I’m so glad.
Looks great! Can we use oven ready noodles?
I don’t see why not. You might have to adjust the cooking time though.
Do you think you can freeze this? Like if you need to travel with it? If so would you bake if then freeze or just make and freeze?
Hi Dani – I personally have not frozen this lasagna, however I don’t see how it would be any different from regular lasagna. You can freeze it either way. It can be thawed in the fridge for 24 hrs prior to baking or cooked straight from the freezer. Obviously cooking from frozen can add on 30 minutes. Thanks for your question!
We really enjoyed this!! I used a bigger pan, thus less layers. Still great.

I bet any kind of noodles would be ok to use.
Looks delicious
I was wondering if anyone has tried this with oven-ready lasagna noodles since that’s what I have in my cabinet.
Loved this lasagna and so did my company!
★★★★★
I’ve made this lasagne many times and it’s our favorite so I wanted to thank you for such a delicious recipe! I add a little garlic and onion powder to the spinach mix and use the barilla oven ready noodles that I cook (not boil) for about 4 minutes.
Love the website and the pure ingredients you use!
★★★★★
thank you! That was so nice <3
I would double the amount of roasted squash and leave some chunks in I would also double spinach mix Continue with 4sets of noodles incl extra spices and u have a winner!
★★★★
Could you assemble, cover and store in fridge 24 hours prior to baking?
★★★★★
absolutely!
So delicious! My first time trying a recipe with butternut squash actually, so a bit exciting to see, but amazingly tasty, my boyfriend and I loved it! We only used about half the amout of ricotta and not mozzarella with the spinach (just on top) and it was still fabulous, thank you so much for sharing!
★★★★★
No one in my family liked this recipe. Maybe time down the spices?
Could you use goat cheese or some other nondairy cheese in place of ricotta?
I made this for my boyfriend last night and he LOVED it! We had it for lunch again this afternoon and ate the rest of the leftovers, and he requested it for dinner again tonight!
★★★★★
