This is a great meatless meal idea too.

I love spaghetti squash and I have found a ton of yummy ways to enjoy it. I love using squash instead of noodles because I don’t really like pasta. But it’s also a great healthy alternative for pasta if you are eating gluten-free or grain-free meals.

It’s easy to cook, and will take on the flavor of anything you put in it just like pasta. But it’s also stuffed full of antioxidants and vitamins and minerals as well as fiber. It’s just an all around great thing to cook. It has a little firmness when you chew it so it’s not soggy and mushy like pasta can be if you cook it too long.

This flavor profile of spaghetti squash lasagna is going to blow you away and you won’t miss the meat or the pasta in it. It’s rich, savory, and really satisfying.

Spaghetti squash is a hard, yellow winter squash that will store on the counter for months so it’s a great storage food. When you cook spaghetti squash, the meat of the squash will flake out with a fork into spaghetti-like strips that can be used in many recipes.

When we stuff them, we mix it with seasonings and other vegetables, meats, and cheeses, and put it all back in the squash skin and bake it a second time to marry all the flavors together. It’s a real treat.

Cut a spaghetti squash

The first concern about preparing a spaghetti squash lasagna is cooking it. Spaghetti squashes are rock hard. A trick I’ve learned about it is to toss it in the oven whole. Bake it at 350 for about 20 minutes. Take it out of the oven, slice off the stem end and easily slice it in half.

Even if you don’t want to precook the squash before you try to cut it, do cut off the stem end before you try. You don’t have to try to cut through that woody stem.

Baked spaghetti squash whole

Now that you’ve baked the spaghetti squash whole, it’s easy to scrape out the seeds. Turn up your oven to 400. Season the squash and place it cut side down on a baking sheet and follow the directions in the recipe from there. All those times I nearly lost a limb cutting my squash raw, who knew this would work so well.

Can you freeze spaghetti squash

Spaghetti squash freezes great. Much better than pasta would. You can bake a bunch of them and scrape the “noodles” out into a freezer bag once they are cooled. Store them in serving sizes for quick “pasta” type meals later. It will last in the freezer for several months.

You can also make this stuffed spaghetti squash lasagna, let it cool, wrap it in plastic wrap or put it in a container and freeze it that way. Then you’ll have your own homemade tv dinner to use when you need another meal.

For even more make-ahead freezer meals that you can prepare ahead, check out this post.

You can make homemade roasted tomato sauce from fresh tomatoes, use spaghetti sauce with meat, make homemade Italian seasoning, and even make your own homemade mozzarella for this recipe. Doing this will make it taste even more amazing.

Growing spaghetti squash

Growing spaghetti squash is similar to growing other types of squash. The seeds are large, so it’s a good project for kids too. It’s a slow-growing squash that grows on a big vine, so it needs plenty of room. It’s a winter squash, meaning it will store well for eating all winter. Check out the highlighted link above for details on how to grow your own spaghetti squash.
