Spaghetti Squash Lasagna Casserole

If you come from an Italian family or know an Italian family, you are clearly aware of the fact they all love a good pasta dish.

Pasta is the Italian staple, especially on a holiday or actually every.single.Sunday.

At least in my childhood that’s how I grew up. I woke to the amazing aromas of an freshly made marinara sauce cooking on the stove, simmering all morning until Sunday dinner at 1pm. That was our tradition and in fact my mother still makes her sauce to this day even though all her children are grown and on their own.

I think she secretly hopes we’ll make a visit on Sunday just for that sauce and often we certainly do.

I would never complain of my childhood around the ever present pasta and bread.

But I did have an issue controlling my portions and that has stayed with me as an adult. Portion distortion is what I like to call it.

Learning to have appropriate servings was something I had to learn in my twenties and to this day I can guess on a serving of something, but then when I measure it out, it is often way more than I thought it was.

I realize there are many conflicting views on weighing and measuring food, but for me the only way I ever had control of my portions to lose weight was having to track and weigh and measure. Eyeballing never worked for me. Ever.

Just eating clean was not enough, even getting rid of sugar was not enough. My portions were out of wack and they needed to be subdued. The only way to teach myself proper portions was measuring it all out.

Not easy, not fun, but necessary. At least in my life, necessary.

So back to my Italian family and their love for pasta, especially on holidays. If you have an Italian daddy like me, ย who happened to come to this country on a boat when he was 15, you will empathize with me here.

I served this on Christmas!

GASP!

I served my Italian father this and called it a healthier lasagna without pasta.

He asked what it was. I quietly began….”Spaghetti……(I hesitated and cringed)……squash”, ย I said in a whisper.

He sighed.

He ate.

He ate some more.

He finally spoke in his still evident accent and a roll of the R in my name, “I like it Brenda”. And he had a second serving!

I felt like I made history that day.

If a stubborn Italian man who loves pasta can learn to enjoy a lower carb mock lasagna, there is hope for us all yet.

  1. About how many squashes did you use to get 3lbs? I don’t have a scale so I want to get as close as possible. Can’t wait to try this!

  2. 5 stars
    I made this last night for my family of 8. Everyone loved it! Even my grumbling teen at this new no-sugar stuff ๐Ÿ™‚ Many came back for seconds…the chef’s best compliment! I think I will make this for our next church potluck.

  3. 5 stars
    I just made this, and it was scrumptious! I’ll never use regular pasta for “lasagna” anymore.
    Really, really tasty!

  4. This recipe says to use 32 ounces of marinara sauce. The marinara sauce recipe says it makes 8 cups. Are you talking about fluid ounces and we should use 4 cups of the marainara sauce for this recipe? Thanks. Jo PS: This would make the division of the sauce be 3 cups to be added to the meat and 1 cup to be added over the cheese layers.

    1. Made this tonight and it was delicious! A hit with the whole family, including 11-year-old granddaughter and husband who has never liked regular lasagna. Portion control is still important, though, if you have diabetes. I ate two portions (it was so good!) and blood sugar went up a little too high so next time I will stick with one.

  5. Admittedly I have not tried this yet but I’d like to. I have made Spaghetti Squash before and usually I only need to bake it for maybe 30 minutes. Is there a reason for cooking it longer?

  6. Love the uses of spaghetti squash in place of pasta. I really appreciate all the work you put into your recipes and that you share them. Awesome! (Minor FYI of typo. The paragraph after the second last picture, last sentence says “emphasize” instead of “empathize”. Your writings are always done with care to detail, I thought you might appreciate the notice. Not being picky by any means, just letting you know. Feel free to delete this part, as it has nothing to do with your hard work on the recipes and willingness to generously share them.)

    1. I love that you mentioned it and caught that for me! I really appreciate knowing I made a mistake as I try to watch and double check but sometimes I do miss them so thank you!

  7. This looks fabulous! Did you have any problems with the squash turning everything into a watery mess? I often find my spaghetti squash dilutes everything else…
    Thanks in advance!

  8. So cool that your Italian dad loved this!! Not easy to please an Italian with something that isn’t typically what they would make (I’m surrounded by Italians;). Fantastic way to enjoy something rich a little lighter!!

  9. You are a very brave woman Brenda! So glad your Italian father liked your Christmas meal. It looks wonderful!

  10. I like to add ground fennel to the lasagna meat. This makes it taste like there is Italian sausage in there(fennel is the main seasoning for Italian sausage). Your taste buds will be tricked!

    1. Or just replace the ground beef with Italian sausage that’s what I’m trying right now

  11. This looks fantastic! My husband and I eat spaghetti squash 2-3 times a month, but I’ve never tried it in a casserole. I’m going to have to put this in the rotation!
    By the way, number 7 on the instructions states “7.Add the remaining sauce over the cheese payer.” Is “payer” = “layer”?
    Thanks!

  12. I have a question. I tried spaghetti squash and it was crunchy. We did not like it in the recipe I made which called for it. Is the squash suppose to be crunchy? I am wondering if I just cooked it wrong. Please respond, this will determine whether I try this recipe or not. Also, I love your website. You use simple foods to make it work. I like that. Thank you much for sharing.

    1. If your squash was crunchy, it was not cooked long enough. The sweet spot for spaghetti squash is between the crunchy and mushy stages. If it happens to you again, scrape out the strands, put them in a covered bowl, and nuke ’em till their done. There’s (almost) always a way to fix a cooking boo-boo.

    2. If your spaghetti squash was crunchy it definitely is not cooked long enough. As someone else said microwave it. I would put it in a bowl if you’ve already scraped it out of the shells cover it with plastic wrap and stick it in the microwave for a few minutes. I also try to drain mine in a cool lender for a while so that it gets some of the moisture out.
