Buffalo Chicken Casserole Whole30

Buffalo Chicken Casserole (Whole30 Paleo) – this spaghetti squash casserole will have everyone going back for seconds.  Huge chicken wing flavor, packed with protein and veggies, and gluten/carb free!

Classic buffalo chicken wing flavor in a comforting casserole with absolutely zero carbs, gluten, or dairy!  It may not be the prettiest, and I know I say this a lot, but I’m calling this my new favorite recipe!  Whether you stick to a Whole30/Paleo diet or not, this Buffalo Chicken Spaghetti Squash Casserole is a must make.

Made with spaghetti squash, shredded chicken, veggies, eggs, and buffalo sauce, this recipe does involve a few steps in the prep stage.  I always prefer simple recipes that don’t require multiple steps to make, but this one is worth the extra bit of time.  I usually make this on Meal Prep Sunday, when I’m already doing lots of prep, and eat it all week for lunch.

Skeptical about spaghetti squash?  I was too but am now a spaghetti squash lover!  It has such a mild flavor that pairs well with just about anything.  It’s delicious topped with a Homemade Bolognese sauce and perfect in casseroles.  It’s also super easy to prepare by roasting in the oven or steaming in the Instant Pot.

How do you cook a Spaghetti Squash?

My favorite method is in the oven.  Preheat your oven to 400 degrees and line a baking sheet with parchment paper.  Cut the squash in half and scoop out the seeds.  Place cut side down on the baking sheet and bake for 40 minutes.  Remove from oven, let cool slightly, and using a fork, scoop out the insides.

Spaghetti squash can also be cooked in the Instant Pot.  Simply cut in half, scoop out the seeds, and cook with some water in the bottom of the pot.  This method is a little quicker, but if you have a very large squash, it may not fit.

How to Make Buffalo Chicken Spaghetti Squash Casserole

  • Prep your Whole30 Mayo or use a compliant brand (like this Primal Kitchen version.)
  • Try using the Instant Pot to prep the shredded chicken and spaghetti squash or roast the squash in the oven.  Rotisserie chicken can also be used here.
  • While the chicken and spaghetti squash are cooking, chop your veggies and whisk the eggs.
  • Throw it all together with the hot sauce and bake!
  • For Meal prep, package individual servings in these glass containers for easy grab-and-go meals.

Topped with Homemade Whole30 Ranch Dressing, this casserole is sure to become a fast favorite and a staple on your Whole30 meal plan list!  Looking for more Whole30/Paleo friendly recipes?  Check out my Whole30 Survival Guide and recipe index!

Notes

Spaghetti Squash Cooking Instructions:
Cut squash in half (use a sharp knife and be careful - spaghetti squash are very tough) and remove seeds. 
Oven: Place cut side down in a baking pan. Roast in the oven at 400 degrees for 35-40 minutes (should be very tender.)  Scoop out the flesh and separate strands with a fork.
Instant Pot: Add about 1 cup water to your Instant Pot.  Place trivet upside down and squash halves on the rack.  Set for 8 minutes using manual function.  When complete, quick release the pressure and remove squash.  Scoop out the flesh and separate strands with a fork.
Tip: I have had the best luck with the recipe when I squeeze the excess water from the squash.  Once strands are slightly cooled, place on a thin kitchen towel, gather up the ends, and wring until most of the water is removed.
