Buffalo Chicken Casserole

Buffalo Chicken Casserole


Here's a fairy tale scenario for you: combine all of the most delicious, clean ingredients you can think of in a casserole pan, bake it, and everyone lives happily ever after, the end. Well, you're in luck. Your fairy tale is now reality. Enter: this casserole. Spaghetti squash, buffalo sauce, chicken breast, carrots, onions, garlic. INTO IT.

The Perfect Make-Ahead Meal

This casserole is a perfect "make ahead" meal that can be taken to work for lunch or eaten throughout the week for dinner. Ryan and I love to pre-make it on Sunday and eat it for dinner during the week with a dollop of Primal Kitchen Mayo on top. So tasty!

Easily Customizable

As a note, feel free to play around with the proportions of spaghetti squash, chicken, and buffalo sauce. The recipe below is my personal preference, but the primary ingredients can be altered a bit and the result will still be a yummy casserole! If you like spicy food or are a big fan of buffalo sauce, I'd suggest increasing the buffalo sauce to 1 cup.
