This is not your average lasagna, Butternut Squash Lasagna recipe is a gorgeous tribute to Italy and Italian flavors! Full Video below for this recipe!

 

BUTTERNUT SQUASH LASAGNA

There are so many ways to make butternut squash lasagna. This version is a recipe I developed some 8 years ago for an Italian cooking class and has been a crowd pleaser since!

Smooth roasted sweet butternut squash flavored with Parmesan cheese and sweetened with Amaretti cookies layered between tender lasagna sheets and a sweet basil béchamel sauce. Top with more Amaretti cookies for a slightly sweet crunch! Oh and we’re not forgetting the cheeses!

This lasagna recipe is seriously a cozy Fall inspired vegetarian meal that never disappoints! The flavors blend beautifully and the creamy squash texture is melt in your mouth with a sweet crunch from the cookies!

In the TIPS section below, I’m sharing ingredient substitutions and different ways to make this heavenly lasagna! Also, can’t help but share this detailed post on How To Make Lasagna With Pierogies  if you’re looking for TIPS and another variation on lasagna!

 

For the squash lasagna, there’s a full recipe video below, and I’ll be breaking down the steps with photos.

HOW TO MAKE BUTTERNUT SQUASH LASAGNA 

First of all, we’ll start wit the squash.

Butternut Squash

A butternut squash in a plate surrounded by milk, parmesan cheese, basil, flour , butter. Ingredients for the squash lasagna

You’ll start by preheating the oven to 400 degrees and line a baking sheet with parchment paper.

For this recipe, I love cutting the squash into cubes and roasting them with salt and olive oil. Roasting the squash develops intense flavor compared to boiling or any other cooking method.

Butternut squash cut up into cubes and placed on a baking sheet, seasoned and ready for roasting

Since I will be pureeing the squash later for the lasagna, I don’t really bother cutting the squash perfectly. Only thing to pay attention to is the size of the squash chunks. For them to roast evenly, try to make them as equal in size as best as you can.

Once roasted and ready (20 minutes later or so), we’ll be processing them.

In a food processor add the squash with some butter, parmesan cheese and some crunchy sweet Amaretti cookies. Read more about the cookies in the TIPS section below.

The butternut squash will be smooth, creamy, silky and delicious!

And it’s ready at this point!

Basil Bechamel Sauce

I have to say that the beauty of this Butternut Squash Lasagna recipe, aside from the squash and Amaretti, lies in the sweet basil béchamel sauce.

The addition of fresh basil to the classic béchamel makes a huge difference and takes this lasagna to a whole new level of deliciousness! Don’t SKIMP on this sauce by all means! Read more on the TIPS section for different ways you can use this sauce!

A pot with a whisk making the bechamel sauce with milk, butter and flour

To make Béchamel sauce, you’ll need to melt the butter in a medium pot. Add the flour and whisk them together for 2 minutes until slightly toasty.

Then gradually add the milk in 3 portions while whisking to ensure the sauce is smooth.

Allow the béchamel sauce to simmer on medium-low heat for about 5-7 minutes until the sauce thickens. Remove the sauce off the heat and add the nutmeg.

A blender with some of the béchamel sauce and lots of fresh basil ready to blend

When the sauce has cooled down a little,  take a third of it and add it to a blender with lots of fresh basil.

The basil béchamel in the blender is ready and green

Blend the sauce to a delicious and beautiful green color.

Place the basil béchamel back in the pot to finish the sauce. Parmesan cheese, and amaretti cookies on top to whisk in the sauce.

Now place the basil sauce back with the original béchamel and mix them together for a sweet light green basil scented béchamel. Add the parmesan cheese and 2 tablespoons of the crushed Amaretti cookies.

Basil Béchamel sauce is ready in the pot.

Season the sauce and set aside.

Assemble the Butternut Squash Lasagna 

Now we’re ready to assemble and bake the butternut squash lasagna. Y.U.M.!

Use an oven safe 9”X13” pan and ladle ¾ cup of the basil sauce at the bottom.

Top that with 2 or 3 sheets of cooked lasagna sheets (depending on the size—but make sure the entire surface is covered), and spread half of the squash puree over the pasta.

Add another layer of sauce,a sprinkle of parmesan, a sprinkle of mozzarella cheese and Amaretti cookies.

Then repeat the layering process two more times.

SQUASH LASAGNA TIPS

  • The butternut squash is roasted here for maximum flavor! However if you have ready cooked squash, you can always use it.
  • The texture of squash I prefer for the recipe is to be pureed. Likewise you can use a chunky mashed texture if you prefer, or chunks of squash, squash rings, however you prefer.
  • I haven’t tried other types of squash here–but I think they would do well to replace butternut squash!
  • Amaretti cookies are Italian almond cookies. They have a delicate crunch and slight sweetness. If you can’t find them use any almond cookies you have.
  • On a side note, I love making amaretti cookies (hello espresso amaretti cookies!! ), but for the lasagna, I would make them without  the espresso 😉
  • Bechamel sauce is not tricky if you follow the recipe. Stick to equal parts of butter and flour and add the milk in three different additions. Always whisk during the sauce preparation.
  • Adding the basil flavors the sauce tremendously but remember to blend it with just a third of the bechamel first. This will ensure that your sauce doesn’t become runny.
  • The basil bechamel sauce is so delicious for pastas, chicken, salmon and veggies! Make extra and keep it in the fridge, and simply warm it before use.
  • The lasagna sheets I used here were pre-cooked al dente, however you can use the oven ready lasagna and skip the extra step.
  • Add in as little or as much cheese as you want!
  • Enjoy the lasagna on the day you bake it or store it in the fridge for up to a week.
  • To freeze the lasagna: freeze the uncooked but fully assembled butternut lasagna covered in foil for up to 6 months. To bake, simply increase baking time by 15-20 minutes.
  • Freezing the cooked lasagna: cover the fully cooked lasagna with foil and freeze it for 6 months. To serve it simply warm it in the oven  (frozen) for 25 minutes, or defrost first and warm it for 10 minutes.
  • Make ahead of time:  prepare the squash as well as the bechamel sauce a day or two in advance. So the day of, all you really need to do is just assemble and layer your lovely lasagna and bake it.
  • ENJOY every bite of this heavenly lasagna!!

    I’m smelling that lovely bechamel right now. I would wear basil as perfume if I could. I love the scent — so clean and fresh. The lasagna dish looks so good and the crunchy addition of the cookies is perfect. What a wonderful alternative to the regular lasagna.
