How to make a Butternut Squash and Spinach Lasagna
- Roasting the Butternut Squash – The first order of business in this lasagna-making adventure is tending to the butternut squash. Whether you decide to start with a whole squash and carve it into bite-sized cubes or go for the convenience of pre-cut pieces, there’s one rule: I recommend roasting it. As a result, it intensifies the flavors, giving it that beautiful browning, and a touch of caramelization.
- MAKE THE BUTTERNUT FILLING: After the roasted squash has had a chance to cool down, it joins forces with creamy ricotta cheese, a dash of milk, and a pinch of salt, pepper, and nutmeg in the food processor. Blend it until it achieves a luscious, creamy texture or leave it a little chunky. It’s up to you.
- MAKE THE SPINACH FILLING: 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:
- Begin by greasing the bottom of a 9 x 13 pan with cooking spray, then spread a thin layer of the butternut squash puree.
- Place three lasagna noodles on top and generously spread the butternut puree over them.
- Follow with a layer of the spinach and ricotta mixture.
- Finish each layer with a sprinkle of mozzarella cheese.
- Repeat this process three more times, topping with a final layer of mozzarella cheese. Don’t forget to add a dusting of Parmesan on top for extra flavor.
- Cover the lasagna and bake it for approximately 30 minutes. Then, remove the cover and broil for a few minutes to achieve a golden, bubbling cheese topping.
What to Serve with Butternut Squash Lasagna:
- Garlic Knots:New York Style Garlic Knots A classic choice that complements the flavors of the lasagna and is perfect for soaking up any extra sauce.
- Green Salad: A simple green salad with a light vinaigrette adds a refreshing contrast to the rich lasagna.
- Roasted Vegetables: Consider serving a medley of roasted vegetables like asparagus, broccoli, or Brussels sprouts for added nutrition and variety.
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.

What’s the nutritional information for this lasagna??
I updated the recipe to include the nutrition info
I made this for a group in for a wellness retreat. Everyone loved it. I made it the night before and cooked it the next day. Worked great. I actually upped the spinach a bit and added a few mushrooms. I only did three layers because I am terrible at judging how much to put in each layer. Will definitely make it again.
I love your additions Tina – I’m a huge spinach and mushroom fan too. Thanks for trying it!
This was lovely! I did not add the nutmeg, but I roasted the squash with a heathy bit of thyme. I also doubled the garlic. I’d suggest if you are using ready noodles to add a cup or two more milk in with the squash! But overall so amazing!!!!!
I have no idea how you got 4 layers with this I did the fillings as thin as I could layer them and ended up with 2 layers total.
How many does this recipe serve?
It would depend on serving size and other side dishes being served as well. But I would say this recipe will feed 8 people.
This was delicious- absolutely best vegetable lasagna I ever had.
Looks delicious
Love that you don’t have to make a bechamel sauce with this recipe. Saves me a step!!
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!
wow! thanks Abbie!
How many servings does this make? I have looked …
My whole family, including my picky kids, loved it!
This lasagna looks so good! Can’t wait to make it this weekend!
