How To Make Keto Spaghetti Squash Casserole
This keto baked spaghetti squash casserole is incredibly easy to pull together.
The longest parts are baking spaghetti squash and cooking shredded chicken (or air fryer chicken breast, if you’d rather cook it that way!), but these are almost entirely hands-off.
I’ll show you how to make buffalo chicken casserole with spaghetti squash. Come make it with me, so you can see for yourself how easy it is:
- Bake spaghetti squash. When it’s nice and soft, set it aside to cool until you’re able to handle it.
- Make the keto buffalo chicken casserole sauce. In a large bowl, stir together blue cheese dressing, buffalo sauce, and cream cheese. Stir in shredded chicken.
TIP: If you want your cheesy spaghetti squash casserole to have more kick, add 2 additional tablespoons of buffalo sauce to the chicken mixture.
- Prep spaghetti squash. Cut spaghetti squash in half and use a spoon to scoop out seeds. Use a fork to release the strands.
- Assemble the casserole. Stir the spaghetti squash into the chicken mixture, then transfer it to a baking dish.
- Top with cheese. A must, right?! 😉
- Bake buffalo chicken spaghetti squash casserole. Since everything is already cooked, this is pretty quick – just to heat it and melt the cheese.
- Garnish. Drizzle with additional blue cheese and sprinkle with green onions.
TIP: If you want more spice after it’s already done, drizzle more buffalo sauce on top.
Is Buffalo Chicken Casserole Keto?
This one is! It’s 12 grams net carbs for a generous 1 1/3 cup serving, which is reasonable for being a full dinner.
If you need to restrict carbs further, you can reduce the serving size to 1 cup by dividing it into 8 servings instead of 6. This would reduce net carbs per serving to 9 grams.
Top with extra blue cheese dressing, or even some diced avocado, to add more calories without additional carbs.
Can You Make Cheesy Spaghetti Squash Casserole Ahead?
Yes, it’s the beauty of spaghetti squash casserole recipes! You have a few options to prep this make ahead spaghetti squash casserole.

Delicious! I used 1/2 C. of Buffalo sauce and didn’t use any extra sauce to garnish. I might mix my cheese in before I bake it next time. Green onions are a nice garnish and add a bit of color.
Cathy
Haven’t tried yet but it looks like it will tick all the boxes!!!
Ariele
just made the buffalo chicken spaghetti squash casserole OMG!!! so good ❤I sauteed some onion, garlic & bell pepper in coconut oil before stirring in the cream cheese, buffalo sauce & bc dressing. turned off the heat, added the chicken & extra blue cheese crumbles before mixing it all together with the squash #ketodeliciousness
dodie
Is it possible to use non-dairy where applicable as I am extremely sensitive to dairy.
Thank you for your response.
Dodie
Wholesome Yum M
Hi Dodie, Yes! There are dairy-free cream cheeses and dairy-free shredded cheese that could be used in this recipe. The blue cheese crumbles contain dairy and I’m not sure if there is a dairy-free alternative for those. They do provide a lot of flavor, so if you can tolerate them I recommend using them in the recipe! Enjoy!
Sharon
oh my goodness, this is delicious. I was afraid of the hot sauce (since I don’t like “hot” food) but it’s a perfect combination and taste. This is definitely a keeper!!
Amanda
Easy and yum!
I only did on thing different. I used half regular cream cheese, half jalapeno cream cheese and also added some diced pickled jalapenos (because we’re crazy). Yes it was spicy but awesome flavor.
I cooked the spaghetti squash and chicken in the oven. So easy. I do wish there were less pop ups and ads on here because it made it difficult to find the recipe and tips each time I reopened it but it is what it is. Next time I’ll screenshot
Thanks!
Sarah
This looks so great! Could you swap the spaghetti squash for zucchini noodles or would that change the flavor too much?
Wholesome Yum M
Hi Sarah, Yes, you can use zucchini noodles! Please follow the tutorial here for The Best Zucchini Noodles. This method will give you the best texture and flavor for your dish. Enjoy!
Sarah
Awesome! Thank you! Would you cook the zucchini noodles in the oven before adding to the casserole or no?
Wholesome Yum M
Hi Sarah, Yes, that way you will work out some of the water from the zucchini noodles before adding them to the casserole.
Christy
I substituted cauliflower for spaghetti squash and it is amazing!!!! Roast the cauliflower first and then incorporate! I make it once a week!!!! ❤️
Christy
This dish is amazing!!!! I made it with ranch instead of blue cheese dressing and everyone who ate it LOVED it. It has so much flavor and is even delicious cold.
Jennifer
This was so delicious – we loved it! When I was mixing the ingredients, I worried that it might be too spicy because the smell is obviously strong – but that was not the case! All the flavors mixed together and it was a nice balance of great flavors! The spaghetti squash add such an interesting texture – makes it much more substantial. This will become a regular in our house!
Lynda Luna
Since I don’t like blue cheese dressing, can I substitute another dressing like ranch dressing?
Wholesome Yum M
Hi Lynda, Yes, that should work just fine. Enjoy!
Katharine
The link to “buffalo sauce” takes you to Frank’s RedHot Sauce in Amazon. I’m assuming this is not correct??
Wholesome Yum M
Hi Katharine, This is correct. Hope you enjoy!
Katie
Made this for the family and it was a hit!

It was good. My son loved it, even though I read the instructions incorrectly and added the cheese to the chicken mixture. It was good and easy. I love EASY!
