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 (we’ve been watching too much Food Network) that makes each bite absolutely amazing. We’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!
We think we may have a minor addiction to buffalo sauce. We put it on just about everything. Burgers, omelets, pork chop, you name it. Without thinking about it too hard we can only think of one thing we would never put buffalo sauce in/on...our morning coffee? Ha! But nothing pairs better with buffalo sauce than chicken (and maybe spaghetti squash) especially when you add a little blue cheese (which we totally did after photographing this as we didn’t think about it beforehand). This is our ultimate meal.
We 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, roughly 10% of the RDI of Vitamin C in a single cup, and plenty of B vitamins. Best of all, spaghetti squashes are typically less than $2/lb so you get a lot of bang for your buck!
