Keto Buffalo Chicken Casserole

This Keto Buffalo Chicken Casserole is a great classic low-carb recipe. You’re going to love this buffalo wing inspired recipe!

To be completely honest this Keto Buffalo Chicken Casserole really shouldn’t really be called a casserole. It should be called a Kick-Ass-Erole.  It’s just so good! The spaghetti squash adds a textural element to the dish (I’ve been watching too much Food Network) that makes each bite absolutely amazing.  I’ve tried versions of this dish that call for just chicken and cheese(s), and it’s less casserole and more of a dip or spread and is far too rich to eat more than a bite or two. This casserole is definitely substantial and filling!

I think I may have a minor addiction to buffalo sauce.  I put it on just about everything. Burgers, omelets, pork chop, you name it. Without thinking about it too hard I can only think of one thing I would never put buffalo sauce in…my morning coffee? But nothing pairs better with buffalo sauce than chicken (and maybe spaghetti squash) especially when you add a little blue cheese (which I totally did after photographing this as I didn’t think about it beforehand).  This is my ultimate meal.

I love making and sharing recipes that have hidden veggies like this one, especially when it’s as nutrient-dense as spaghetti squash.  The “Squaghetti” contains a surprising amount of omega-3’s which aids in reducing inflammation, roughly 10% of the RDI of Vitamin C in a single cup, and plenty of B vitamins which promote optimal cellular function.  Best of all, spaghetti squashes are typically less than a $2/lb so you get a lot of bang for your buck!

Do I have to use a skillet?

No, you can totally use a baking dish!

Can I use rotisserie chicken?

Yes! If you are short on time you can use shredded chicken from a rotisserie chicken. Just skip the step where you cook the chicken.

You can store this casserole covered in the refrigerator for up to 5 days.

Can you freeze this keto low-carb casserole?

Yes, you can! Simply freeze portions of the casserole in freezer-safe containers. To reheat simply microwave or place in the skillet on the stovetop until the cheese is melty and the casserole is heated through.
