Winter Squash Basics

Most often, winter squash is associated with the fall as that is their best growing season, but of course now in the United States it is available all year.   Winter squash includes all varieties of squash that grow during the cooler seasons of the year.  Butternut squash, acorn squash, buttercup squash, delicata, pumpkin and many more!

One thing they all have in common is that they generally have a tough outer skin and are quite firm before cooked making them hard to peel and cut.  But, did you know that you can actually cook it whole and completely intact?  Cooking first actually makes it easier to peel, cut and deseed.

The ingredients

Pasta

You can use regular lasagna noodles or take a short cut and use the noodles that you can cook in the oven thus eliminating the step of boiling them first.  I found that the size of the oven-ready lasagna noodles ended up working really well as they fit lengthwise perfectly in the 1 1/2 liter square pyrex baking dish I used (6.5″ x 8.5″).  I used 2 noodles in each layer of the dish, so in total I used 6 of these lasagna sheets.  Depending on the size of your noodles and the dimensions of your baking dish, you may need more or less.

Spinach

In the recipe for this winter squash lasagna, I used fresh spinach.  I started with about a half pound of fresh spinach and boiled it in down in a couple tablespoons of water.  It doesn’t take long, only 1-2 minutes.  Another option is to use frozen spinach that you’ve allowed to thaw out.

For me, I personally enjoy fresh spinach, and the other factor for me is that frozen vegetables are not readily available here in Peru. Whichever you choose to use, just make sure you squeeze as much of liquid as you possibly can before adding it to the ricotta cheese.  Too much liquid will result in a watery lasagna.

 

Different varieties of winter squash work in this dish. Pictured here is zapallo loche a squash in Peru which the flesh is similar to butternut squash.Squash

My top pick for the winter squash in this dish is butternut squash, but at the time I first made this dish, it was the start of spring in Peru and butternut squash wasn’t available.  Instead, I used a type of squash found here in Peru called Zapallo Loche that is very similar to butternut squash in flavor and consistency.

Other varieties that would work well in this recipe are buttercup squash or kabocha squash.  Depending on the consistency of the puree of the type of squash you use, may require you to adjust the amount of stock you add to create the butternut squash sauce.  You want it to be a consistency to be similar to marinara sauce as this will add some moisture to the lasagna and help cook the lasagna noodles.

Making squash puree

If you are lucky and can locate a frozen or prepared squash puree that is fantastic but if not, you can easily make your own squash puree, by roasting it in the oven.

Just poke some holes in the outside and put it in the oven intact.  Most squash will cook in about 45 minutes or so. You know the squash is cooked when you can easily slide a fork into the flesh.  Let it cool and then peel and deseed the squash. Next, place the flesh into a food processor or blender to create the puree.  I will generally do this step on a weekend and then freeze the puree in one cup amounts so when I need it, I can just defrost and use.

The nutrition

This winter squash lasagna recipe is a vitamin A powerhouse and one serving provides 137% of the RDA for this nutrient.  The vitamin A comes from the carotenoid in the squash and the spinach, which is also what gives the squash its yellowish-orange color and contributes to making the green color in the spinach. Vitamin A is mostly found in plant-based foods and in the form of beta carotene, which is converted into vitamin A by the liver.  Sweet potatoes, carrots, kale and spinach are other vegetables with higher amounts of vitamin A.

Vitamin A is of most importance to our eyes and without proper levels it can cause blindness.  However, it also has functions related to our immune system, overall growth and development, the maintenance of our epithelial cells and bone growth and maintenance.

Notes

Use regular noodles in place of the oven-ready lasagna sheets. You will need to boil these first following the instructions on package. Be sure to not overcook the noodles, they should be al dente as they will cook more once in the oven. When they are ready, remove and layout flat to dry out.
