The longest parts are baking spaghetti squash and cooking shredded chicken, 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.

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.

Top with extra blue cheese dressing, or even some diced avocado, to add more calories without additional carbs.

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!
