Spaghetti Squash Casserole

This post was written last November, and I thought I would repost it since the recipe was so good, and it fits well with the Squash Fest.  Unfortunately, it does contain cheese and is not dairy free unless you use a substitute.

Spaghetti Squash Casserole | The Gluten-Free Homemaker

My only experience with squash that I remember from childhood was when my mom would slice, batter, and fry yellow squash.  I hated it.  I hated the flavor and texture.  That experience led me to believe that I didn’t like any squash.  Somewhere down the road I learned to like zucchini, and it has been a staple vegetable in our house for a while.

Other than that, I stayed away from squash until last fall when I made butternut squash soup.  My family wasn’t too thrilled with it, but I enjoyed it.  I made that soup again last week and their tastes had improved to tolerating it.

The second time I bought a smaller squash and cooked it in my pressure cooker.  It turned out a little bit too done and the strands were not as distinguishable.  That was okay because I decided to use it in a casserole.  I didn’t have any ricotta cheese to make a lasagna type dish, so I decided on a variation of my pizza casserole.  It turned out great, and everyone liked it!  My oldest said he didn’t mind the squash as long as there was plenty of meat and cheese, which there was.

spaghetti squash in pressure cooker If you’ve never cooked a spaghetti squash before, there are several ways you can do it.  You can bake it whole by putting some holes in it with a sharp knife or a skewer and placing it in a pan.  Bake it at 375 degrees about 1 hour.  You can also cut it in half, clean out the inside and bake it cut side down in a pan with some water for 30 –40 minutes.  I cut it in half and placed it in my pressure cooker.  I cooked it under high pressure for 10 minutes, but 8 might have been better.

When it is done cooking, use a fork or large spoon to pull out the flesh and scrape it away from the outer rind.  It will look something like this.  For this recipe you should cook the spaghetti squash first and have it ready to go into the casserole.

Spaghetti squash is a great alternative to pasta, especially this time of year when they are in season and inexpensive.  It’s an easy way to make a gluten free dish, but this recipe is worth making whether you have to eat gluten free or not.

    Yum,, this looks really good. I get a lot of push back from using this squash. What a great way to hide it from my hubby. I'll be using this next time I get a spaghetti squash. Thank you for sharing it on Friday Foodie Fix.

    I just bought a spaghetti squash for the first time. I may have to try out this recipe. Thanks.

    Spaghetti squash was never a favorite of mine but, I think it's because it's never been done right everytime it was served to me. This recipe looks good. If I can get my hands on one, will have to try this.

    I love spaghetti squash. My hubby, not so much. You can also prepare it in the microwave – poke holes in it and cook until tender, like 8 minutes or so!

    Thank you for showing how to cook it and how to make it look like spaghetti. I thought I was the only one to never eat or cook squash. My reason is the same as yours. So far this Fall I have cooked pumpkin and found it far superior to canned, made Butternut Squash Bisque and it was not only fun to make but good to eat. I looked at a spaghetti squash at the grocery store this week, now I can buy one and actually know what to do with it. I am enjoying branching out very much. My family is more reluctant but maybe slowly but surely. Thanks.

    Thanks for sharing this again – I missed it last time around. This is going on my menu this week!

    Looks really good! I'm glad you posted it again since I missed it last year :-)

    These look really good, Linda! Yep, same requirements for squash dishes in my house–meat and cheese. I might have to start buying the Daiya (sp?) to keep both of us happy. Well, unless I make pureed and sweet squash recipes, which I do, but that wouldn't work with spaghetti squash I don't think. 😉

    This has to be the BEST spaghetti squash casserole I’ve ever made! I’ve always liked spaghetti squash, but my boys and hubby have always turned their noses up at it. I do make mine with Italian sausage. The little one just calls it spaghetti… score! To add more flavor to the squash, I dizzle olive oil and sprinkle with salt and pepper and roast in a 425 oven for 45 minutes. I don’t drain off the olive oil but mix it in as I’m scraping out the flesh. OH MY… it adds so much flavor. Thanks again!!!

    Hi, Just made this with a few changes..I used turkey, tossed in some mushrooms into the pan to cook up with the turkey. When I did my layers, I added some sliced zucchini and sprinkled some hot pepper flakes and Italian herbs. I cooked longer to 45 min, and boy was this delicious…very very filling.
