I got this spaghetti squash casserole recipe from a friend a few years ago. And she got it from Betty Crocker, I think. She made it for me a few times when I had a baby but original calls for regular white pasta. It’s Betty’s recipe.:) And you know me. After trying spaghetti squash quiche I have experimented with a few casseroles using spaghetti squash instead of traditional pasta and loved the end result.
This spaghetti squash casserole was super juicy and saucy but still holding together. It was just perfect by all means and extremely delicious! I hope your whole family will enjoy this spaghetti squash casserole and maybe you could make spaghetti squash mac and cheese for them next?!
How to Cook Spaghetti Squash
I find the best way to cook spaghetti squash is to bake it for 30 minutes at 375 degrees F. When you take it out it might appear undercooked and not separating easily into strands but it will soften up while cooling down. Do not overcook spaghetti squash otherwise it will be too soggy, and we want it to be crunchy.
How to Replace Spaghetti Squash with Pasta (For Kids)
My kids do not like spaghetti squash, so I made them another one with whole wheat spaghetti. Instead of spaghetti squash use 7 oz whole wheat spaghetti cooked as per package instructions and skip the 1/2 cup breadcrumbs in the turkey squash mixture.
How to Make Spaghetti Squash Casserole
- Preheat oven to 375 F degrees. Cut squash in half lengthwise and spoon seeds out. Punch randomly with a fork, place cut side down on a baking sheet lined with silicone baking mat or unbleached parchment paper and bake for 30 minutes.
- Remove from the oven, let it cool and separate into strands with a fork. Place in a large bowl and set aside.
- While squash is baking, preheat large non-stick skillet on low heat and add avocado oil. Add garlic and onion, saute until translucent or for 4 minutes, stirring occasionally. Add turkey and cook for another 7 minutes, breaking into pieces with spatula.
- Add mushroom soup, tomato sauce and cornstarch, stir and bring to a boil by raising heat to medium. Reduce heat to low and simmer for 5 minutes or until mixture has thickened a bit. Remove from heat, add cheese, stir and transfer to the bowl with spaghetti squash. Add breadcrumbs and gently mix to combine.
- To make the topping in a small bowl, melt coconut oil or butter in a microwave. Add cheese, breadcrumbs and mix.
- Reduce oven temperature to 350 degrees F and spray 9″ x 13″ baking dish with cooking spray. Transfer squash and turkey mixture into the dish, level with spatula, sprinkle with topping and bake uncovered for 35 minutes or until the edges are bubbling. Broil on high for 5 minutes or until crust is a bit golden.
- Let cool for 15 minutes before serving. Cut into 8 slices and serve hot.

*For the whole wheat pasta version, instead of spaghetti squash use 7 oz whole wheat spaghetti cooked as per package instructions and skip the 1/2 cup breadcrumbs in the turkey squash mixture.
**If you can’t find organic cream of mushroom soup, look for a brand with no preservatives and artificial flavours.

Olena, I so appreciate all the work and effort you make to share healthy and delicious receipes. You should have your own Food Network Show and get paid. I have followed other receipes for spagetti squash and am sticking with this one going forward. My family enjoyed this caserol so much that we now have spagetti squash more often in the week.

Awe. Thank you for your wonderful review, Carmen. Maybe one day.:) Enjoy and be healthy!
I was very skeptical to make this but so glad I did! Incredible! We ate for leftovers two nights in a row and were excited for them!
★★★★★
So happy you stepped outside of your comfort zone and I didn’t disappoint.:)
This was a bit time consuming dish but so tasty!
★★★★★
This sounds yummy. Do you think I could substitute ground chicken for ground turkey?
For sure!
This looks AMAZING and I will definitely be trying it- but is it really possible to freeze a spaghetti squash bake without it turning to soggy mush later on??
I’m sorry but NO. It’s gonna be yucky. Why you want to freeze it? Make half or cook half at a time. Keep assembled refrigerated for a few days and then cook. It is a very light casserole. You can eat a lot of it.:)
Actually it freezes beautifully! Just don’t put the topping on it, do that fresh when you’re ready to cook it.
Really? Spaghetti squash doesn’t obtain this kinda separated veggie texture after thawing? You freeze it cooked? No, I think assembled since you are talking about putting topping after. Have you tried to freeze it cooked?
Made this tonight my husband is addicted to spaghetti squash but I wanted to try something new. It was so delish. I put some kale in to saute with the onion and garlic. I even found gluten free Panko. ..not as good as the real thing but what the hell. Husband I loved one 15 year old twin loved. ..The other twin tolerated..and the 18 year old doesn’t like anything. Was sooooo good. Thanks again for another great recipe ♡
Love kale anywhere! You can also use whole wheat panko (there is one) or even better Nature’s Path Smart Bran cereal – organic, clean and high in fibre. Yeah, I have a 4 year old who is hit and miss too. I keep making and serving and he is getting better but it’s a struggle. My 8 year old eats everything!
Do you think it would be safe to try drained tuna in place of the ground turkey? Just curious what you think! This recipe looks awesome
I am personally not a fan of saucy tuna casseroles so I would rather use tofu or veggies (bell peppers, mushrooms, zucchini) instead. Even chickpeas. That’s me.:)
im trying this tonight. I’m not much of a cook so wish me luck!
I hope you made it safe and sound.:)
This is wonderful!! I made it 2 days ago when I was cooking for the week. My husband put it in the oven before I got home and I walked into a house that smelled great and immediately sat down to eat. Thank you so much for creating such a simple, healthy and figure-friendly casserole with the added benefit of being able to sit in the fridge for a few days. I put it in 2 pans so we’ve now eaten one and the other is in the freezer for next week.
Just made it for dinner, and love it. It was my first time cooking with spaghetti squash, and I’m very happy with results. I did have to substitute cream of mushroom soup with some chicken broth and heavy cream, as I didn’t have any, it turned out great. I will try with mushroom soup next time. Kids liked it too. I told them that its mac’n’cheese kind of thing, the “squash” is kept a secret, for now. Thanks for the recipe.
Yay! I was thinking any can of organic creamy soup will do – butternut squash, creamy chicken soup etc. For kids it’s mental many times. If they don’t know what it is they will eat it, but if they knew – big drama!!!
Yum! I love spaghetti squash, and often use it in place of pasta. I’ve never thought of using it in a casserole- this looks perfect for a chilly fall day!
As long as you don’t overcook it before adding to a casserole, it holds really nicely – like pasta.:)
Can you sub the mushroom soup ??
I haven’t tried to sub it. Sorry can’t tell.
When you say a can of mushroom soup is the a cream of mushroom soup or more of a mushroom broth?
Cream of mushroom.:) Try to find a healthy one.:)
This looks soooo amazing 🙂 definitely trying next week 🙂 thank you for a great site!
So welcome.:)
I have made alot of your recipes and this BY FAR is one of my favourite. . . right up there with the cauliflower/egg white recipe. What a nice creamy dish and so flavourul. I would have never thought to use spaghetti squash instead. Fantastic idea! My family loved it. . . the people that we had over for dinner asked for the recipe 🙂 Thanks so much Olena!
You are welcome Sweetie Pie.:) That’s what good friends are for.:)
Hi! I’d like to give it a try but I would like to know first..can squash spaghetti get to the freezer? cooked or uncooked? I know cauliflower can but i don’t know about squash…
Congrats on the recipes and the pictures! They are wonderful!
Hi there. Yes, you can freeze cooked spaghetti squash by itself. Separate into strands and freeze in an airtight container or plastic ziplock bags.
As for this spaghetti bake, you can also freeze it no problem uncooked or cooked. I’ve frozen the whole dish assembled and then just took it out of the freezer and baked. As well as cooked cut into pieces.
Thank you for your kind words.:)
