Spaghetti Squash Lasagna
Are you a big fan of spaghetti squash like me? We just love it in our home! So I thought I’d take my Stuffed Lasagna Spaghetti Squash recipe and make a more traditional meal. This Spaghetti Squash Lasagna has layers of spaghetti squash noodles, cheese, and a meat sauce to make it just like real lasagna without all the carbs! You guys have asked for healthy meals, so here it is. It was even approved by my meat and potatoes kind of husband!
One that even the kids won’t turn their noses up at! Seriously, they LOVED it. A meal that’s healthy and both the kids and husband enjoy is a win in my book!
And shhhh! Whatever you do, don’t tell them it’s healthy!
Oh yes, this is a thing! Tender squash, topped with a meaty sauce and cheesy goodness. It’s baked until golden brown and bubbly; served up just like your favorite lasagna that uses pasta – only healthier!
We actually love spaghetti squash around here and it’s one of our go to side dishes. Usually I just roast it, shred it and throw it in a skillet with some garlic and then serve it as a side dish. But today I decided to make it a meal for you since you guys seem to struggle with healthy meals that will please your family like I do! The keys for healthy meals around here are that they have to be ate by the entire family because I’m not a short order cook and that we truly do enjoy them and don’t think of them as “weird”!

Can i freeze left overs?
Courtney says
I am not sure how this would turn out. Please let me know if you try it. I am concerned about the water content of the spaghetti squash.
Deborah Findley says
Yummy. I used Italian ground chicken sausage, what was on hand. Used my home made spaghetti sauce. It was something my husband loved. Eager to try other recipes. I prefer meatless but finding something he likes is major. Thank you. D
Courtney says
Yum! That sounds great!! Thank you for giving this a try!
Ashley says
This hit all the flavors I want from a lasagna and gave me a great alternative that I’ll likely make more often than regular lasagna now!
Julie Evink says

Bethany says
Hi, this looks delicious! Does this freeze well?
Julie says
It should freeze pretty well! Freeze before baking and leave the shredded cheese off until you are ready to bake it.
Tammy says
Thank you for getting back to me. But what exactly is the serving size as it is not on the nutritional label.
Julie says
It would be 1/6 of the entire dish.
Tammy Rokosh says
Hello, I’m just curious about the nutrition label. Are these amounts pet serving? If so, what measurements of serving or does the whole lasgna consist of the measurements of eating it all. I hope you understand stand my question. Lol.
For example…I believe this lasagna gas 378kcal. So is that pet 100g serving or different serving size?
Thanks in advance!
PS..I’m just waiting for it to come out of the oven. Looks amazing and I can’t wait to try it. ☺️
Julie says
The 378kcal is per serving but those numbers are approximate – it really depends on the brands of ingredients you use. I hope you enjoy it!
Peggy says
Delicious lasagne! Not the typical lasagne taste, but a nice variation. Will definitely make this again! Adding sausage would be a nice addition as well.
Julie says
Thanks for the review! I’m so happy you enjoyed it, sausage would be a delicious addition!
Sherri says
I plan on making this tonight for dinner, but I’m going to add sweet peppers, mushrooms and I think some spinach. I might use Italian sausage in place of hamburger.
Julie Evink says
Hope you enjoy it!
Danielle Green says
This looks absolutely phenomenal!
Julie Evink says
It’s a win for a light and healthy meal in my family!
Malinda says

Julie Evink says
Yes they will!
Melissa Howell says
This is such a perfect idea for a low-carb meal! Super yummy!
Julie Evink says
Low carb and not lacking at all in flavor!
LaTrina says
Looks great but I have a quick question..I also saw your recipe for the lasagna boats using the spaghetti squash and does the moisture that you warn about affect the texture of the boats as well? If so can that be alleviated? Thanks!
Julie Evink says
I find the best way to make the spaghetti squash with the least amount of water in it is to cut them in half, season it with salt and pepper and then bake it. Spaghetti squash will always have a little bit of water.
Kate says
I make the spaghetti boats, when we have the Missionaries over for supper. Lots of fresh made bread with butter fills them up. The lad who was here last week took a picture an sent it home to his family in Utah. I scrape it out of the shells put it back in an put the spaghetti sauce on top with melted mortadella
